Excessive RTV that seeps into the contact area with the coolant will eventually break off and clog radiator and heater core passages, reducing engine cooling and heater operation. Water pump manufacturers do NOT recommend applying RTV or any gasket sealer unless specifically specified Usually sealer is used to hold the gasket on the water pump. If it is not used the gasket will become wrinkled or possibly fall off during install. It can be applied randomly and not really needed.. Don't apply sealant to an O-ring or a dry seal When changing a water pump, replace all old gaskets and seals with new ones. If your new pump comes with a seal, make sure it's in impeccable condition before installing it. (Some seals are so thin you could easily damage them when you rip off the packaging. If it is really goofy, get some carburetor cleaner and spray it on and then rub all the stuff off so it's bare metal. You can do it that way. You don't need sealer on the pump gasket if you already put the sealer onto the pump. The gasket is good enough on the engine, you don't need to put sealer on that For water pumps, oil pans and timing covers I use Aviation Form a Gasket, a light coat on each side of the gasket and I've never had a leak. The Permatex sealer Brian shows would be an excellent choice because it is non-acidic, although I've never personally used it, I would certainly consider it. 6 67FREA
Sealants can add thickness, which creates uneven clamping force since the gasket will not be able to seat properly. Also, sealant can extrude out when the gasket is compressed, and it could end up in an oil or coolant passage and restrict or block flow. Surface Finish: The sealing surface should be clean and dry Use and Misuse of Sealers Fel-Pro, ASE Certified Master Technician, John Gurnig provides examples why most Fel-Pro gaskets do not require the use of sealant. In certain cases, however, it is required when mating gaskets or filling gaps. He shows where sealant should be applied on certain gaskets and in what amount No. If the gaskets are metal (most likely copper) they're high-torque gaskets. They are meant to be tightened so much that the metal actually forms to the block and water pump. Make sure to follow.. Putting on a new water pump kit and just need some clarification. The manual says apply some gasket sealer to the impeller plate gaskets. FYI, j25hp '81 and the kit comes with 2 gaskets, wp housing, etc. Do I have to apply sealer between the water pump housing and gasket as well Anaerobic gasket makers and flange sealants are designed for sealing assemblies where two close fitting machined metal surfaces come together. They're generally recommended for gaps of up to 15 to 20 thousandths of an inch only. If you've got larger gaps - such as sealing a stamped steel oil pan, you should be using an RTV gasket maker
John, a Prestolite Performance engineer, uses Mr. Gasket's Ultra Seal Water Pump Gaskets to install an electric water pump on a small block Chevrolet engine... Preparing to replace the water pump in my '99 3800 Series II NA with 152K in an Olds Intrigue. Am I silly considering buying a Felpro gasket for $5 when a thin paper gasket comes w/ the water pump (Autozone Duralast)? What sealant do you folks use on the gasket? Both sides So no way would you ever need to use a gasket and sealer at the same time. Just a thin material to seal the scratches is all that is necessary. Too much sealer and you could get a leak. Just use a gasket and you will be good to go . When I pulled it all apart I found my truck had the same metal/rubber gasket as the one I got with the replacement in the pic above. There wasn't any RTV on in there so I decided to just put it back the way it was without any RTV. I held a couple of bolts through the water pump as I put it on to hold the gasket in place
That gasket failed after 21 years and 70,000 miles. The new OEM water pump came with a steel gasket that uses I rubber seal around the pump to block contact surface. It looks like there was a design change at some point to go with the steel and rubber gasket over the PTFE liquid type So I went out this morning and put on the water pump with the old metal gasket without any rtv. I couldn't get the surface completely dry, since every time I would start tightening down a bolt ( star pattern, first by hand, then to 10 ft-lb, then to 15 ft-lbs ) a little water would dribble out from inside the engine My car has a paper gasket in there; if your replacement gasket has no plastic coating and your sealing surfaces are having scratches/pits apply 1/8 inch (3 mm) wide bead of ultra-blue Permatex gasket sealant to the both sides of this gasket. Plain piece of metal is only good on the new parts If excess sealant is applied to the gasket and it flows into the coolant system and the pump's shaft seal, it can cause seal failure in a matter of miles. 2. Dry Rotation of the Pump Marprox Sealer 1000 or OMC Adhesive or Boat Armor Sealer 1000 (same substance) [See Below Note] should be used on any metal to metal (Unless GelSeal Is Called For) or metal to plastic surface (such as impeller hsg to plate, and plate to lower unit surface) to eliminate air leaks
Water pump outlet/inlets, thermostat housing, fuel pump, anything else? Should I just use the gasket, just use a sealant (Permatex or other), or use gasket AND sealant (both sides of the gasket?) when I'm putting the water pump, thermostat neck, etc. back on an FE assembly NOTE: I have a big block and the water pump holes are blind. I believe the small block has holes that go all the way into the coolant passages, so a sealer is needed, instead of Locktite. Also Felpro gaskets probably weren't necessary, but they were only a few dollars. I didn't want to run the risk of having to do the job twice due to cheap. The metal gasket has a self-adhesive coating that would self seal when heated up so it is not necessary to add any sealant, unless the block surface is not level or pitted I'm in the process of replacing the impeller and associated gaskets on my Nissan 6hp 4-stroke. I separated the lower pump case from the gear case. Do I need to put some gasket sealant on the paper gasket when I reassemble, or will the paper gasket alone do the trick. (This gasket keeps lower unit oil in and water out. The spiral wound gaskets combine soft plastics or rubber with some kind of metal. Often, these types have layers of material, which increases their strength. Spiral wound gaskets have exceptional stress and thermal resistance characteristics but are also flexible and, with the right adhesive, seal well
Hi there - no, gasket sealer should not be required. the thermostat should come with an o-ring, and the water pump should come with a paper-like gasket. Neither should require gasket sealant as long as the o-ring and gasket are supplied and used as instructed. For assistance, I recommend a [water pump replacement](Hi there - no, gasket sealer.

NICE ! Was easy to clean the sealant off. New gaskets and more 22071. A thin layer that completely covers gasket, is all it takes. New water pump and back in business. Lays out real nice, does not dry up, roll into balls or stick to nitryl glove. Is not silicone. Is more a super smooth paste in a tube. I still like the Permatex Aviation 3. i used a little on both sides. i did one side and put it on the water pump for a few minutes for it to tack on. then just enough to line around the gasket on the other side. Dec 16, 2010 #3 Yep I agree that you should put sealant on both sides of the gasket . It fills the gap between the engine and the water pump in your vehicle. Preventative Functions. Without the gasket, the coolant flowing between the water pump and the engine block would undoubtedly leak out
I had posted a thread this morning looking for recommendations on gasket sealer since I had discovered a leak in my water pump after about 15 minutes of running my new engine. Had my friend at NAPA order what I thought was the right gaskets for a pre 1994 Ford 5.8L engine (mine is a 351W based 410) and using the Ford M-8501-G351 water pump. Haven't been able to find details on water pump repacement with regards to using a sealant / RTV on the gasket or not. It's a rubber coated metal gasket so that's why I'm questioning the need for sealant. Never delt with this kind of gasket on a water pump before Actually, it's a good idea to use thread sealer on all the water pump bolts. Aluminum pump housing, steel bolts, cast iron block, aluminum front cover --- AND the possibility of coolant in contact with the some of the bolts. All potential for multiple types of corrosion Never use sealant here, and when it comes time to change the water pump, the gasket usually sticks to the old pump and what does remain on the block comes off with very little work (most cases it picks right off with a finger nail). Then a light buffing with 600 grit sand paper to clean the surface. ____
A decision to change the belt now, but not to replace the water pump at the same time, assumes that the water pump will last for another complete duty cycle of the belt. Do the job once! Gates recommends changing water pumps whenever belt kits are fitted and recommends the replacement of old gaskets and seals with new ones I always put on a pump straight out of the box with felpro gasket between the pump and plate, felpro gasket between the plate and timing cover with a thin layer of Ultra Black RTV on both sides of gasket and make sure you put sealer on the threads of the 4 long bolts that are next to the water ports. Never had one leak, ever
The thinner the Gasket the STRONGER the SEAL, with a thick paper gasket, the water pressure from the pump turbine is flowing against PAPER not METAL if you take most of the paper out of the equasion then you are forcing water pressure on more metal than on paper and there will be less bowing of the metal between the bolts holding the back plate. . you may want to use a feeler guage and check the tolerances of.
While water pump and water outlet gaskets are trending toward molded rubber designs, some of these gaskets are paper. Paper is still a reliable choice and Fel-Pro proprietary Blue Stripe® paper gaskets provide effective sealing solutions Without properly venting the air out of the seal chamber area, the mechanical seal seals air, not cool water. This is a dry-running condition that generates heat and quickly degrades the materials at the sealing interface. A common environmental control used in vertical applications is a recirculation line from the seal chamber to pump suction. Many gaskets today feature a metal core (usually aluminum) with a computer-printed sealing bead placed on each side. The sealing beads generally consist of an elastomer or silicone material. The metal core serves as a platform for the sealing beads, and aids in preventing over-tightening, since the metal core acts as a stopper layer
NOT a Blown Head Gasket! Thought I had a failing water pump but turns out to only be a small leak at the heater core hose.. Lot better than a $350 dollar mec.. What I was taught years ago by an old mechanic was if you do everything right you don't need gasket sealer, the pupose of the GASKET is to seal. If you need something to hold the gasket during assembly then a little bit of 3M weatherstrip glue will do the job. bigdog, Apr 22, 2007 SHARE POST # A gasket is a part that provides a mechanical seal between two surfaces. In the case of your water pump gasket, it seals the surface between the engine block and the water pump, preventing leaks from the coolant that flows through the water pump Use a new gasket and it should seal fine. If you feel the need to use sealant (I always do) use one made for the application. It is a flange so use a very thin film (no more than.010) of Loc-tite 518 on both sides of the gasket. torque the housing down evenly so you don't crack it and make sure the thermostat stays in place while you put it on U need the metal plate to seal the pump. If you take the plate off the blades are there. On the reverse rotation pumps and timing covers they don't seal on the cover except the pump to the water jackets. But the back of the pump is sealed by the plate and the gasket between it
The Edelbrock sealer comes in a re-sealable 4-ounce container and has been formulated to have oil and water resistance, making it useful on oil pans, water pumps and valve cover gaskets.

According to AA1Car, most water pumps are designed to go 100,000 miles or more, but it's not unusual to see leaks occur after 50,000 or 60,000 miles. Replacing the entire water pump is often necessary in putting a stop to the seal leak
2. On metal tapered fittings, coat the threads with paste-type pipe sealant, also called pipe dope. Brush the sealant onto the threads all the way around the fitting, then assemble the joint. 3. To increase the water-tightness of a plumbing connection apply pipe sealant and then wrap wicking (string) around the threads before assembling the. Sealants work great as temporary fixes but eventually if a gasket leaks you'll need to replace the gasket. Using sealant as a temporary fix for leaks only works with paper gaskets like on a clutch, ignition or water pump cover. It still requires disassembly but you can add sealant and keep riding until the new gasket arrives I've removed, re-doped and replaced the two long bolts on the left-hand-side of my D2's water pump twice now. Both times using Permatex thread sealant. Both times, after a while, it starts leaking. The leak isn't bad, but it's causing the bolt to start to corrode. So! What thread sealant out.. . These gaskets are slightly thicker than the embossed steel style, to help compensate for casting resurfacing. Also, these gaskets are less susceptible to liquid leaks than metal face styles There is a thin paper gasket between the block and the inner cover that provides the water seal (there's also an o-ring behind the impeller). In contrast, there is no gasket at all between the outer and inner covers that provides the oil seal for the timing chain; it's just a metal-on-metal interface that you coat with sealant
The timing cover must be flat and free of corrosion around the water inlets. Use the top bolts that go through the water pump for alignment only at this point. No need to tighten them yet. The pan is the fun part. If using the stock 4-piece gasket, the cork strip is the best bet for the rear lip Start the engine, and allow it to idle for 20 minutes. Don't rev it up to get it up to temperature faster; this will cause the water pump to force coolant through the leak in the head gasket before the metal is up to temperature, preventing the liquid glass from hardening and establishing a seal 4. Permatex High Tack Gasket Sealant. CHECK PRICE ON AMAZON → It is the best head gasket sealer for general purpose applications. With a temperature range of -65 to 500F, it can be used on cold and hot engines, and other components like fuel pumps, valve covers, manifold gaskets, composite gasket, and carburetors My 2002 has started to leak on the passenger side water pump gasket. So, I decided to replace the water pump with a new AC Delco #252845. This unit comes with new silicon lined gaskets. I don't know if these are still from the original design or not. I also noticed that AC Delco has made a change to the gasket sealing surface on their. I recently did a water pump/timing belt change on my 2uz-fe. To my horror, after starting it up and driving around I noticed I was losing a lot of coolant from what I suspect is the water pump gasket. Today, I tore it all down and I'm ready to install the new gasket but I want to be absolutely sure it wont leak this time
Inside the pump is an impeller (which might be made of either metal or plastic) with blades that push the coolant through the pump and out around the engine.

When using flexible non-metallic gaskets, the ability of the joint to hold internal pressure depends on friction. The minimum compressive stress will need to be high enough to maintain the friction needed to keep the gasket from blowing out from the internal.
I am a real mechanic and would never use grease on a water pump gasket. A very thin coat of RTV blue, let it tack up out the gasket on the pump and install. They also make a cement that is made just for paper gaskets that also works very well. Just be sure to be very sparing and let it tack up before applying the gasket and take your time RockAuto ships auto parts and body parts from over 300 manufacturers to customers' doors worldwide, all at warehouse prices.

Intentionally blank: Intentionally blank: Related Parts I've seen one machine overheat constantly because of the gasket sealer covered 90% of the water jacket ports at the exhaust flange. Another good thing to do on anything like this that vibrates is to make a sharpie mark on the side of each bolt and on the manifold and check it after the first hour of use to see if any bolts backed out
Use no sealant on any gasket which is installed between two machined surfaces. 2.) When installing a gasket for a sheet metal cover, straighten the cover as well as possible first. Thick cork or rubber gaskets should not need any sealant, but if you feel the need to glue the gasket in place for ease of assembly, glue it to the sheet metal cover. Looks very similar to the 4.7 gasket that uses no sealer. I don't think the metal one uses any. Make sure and install the two new o-rings and either soap them or use spit when you push the pump on and the water housing on. The sealant around the water inlet housing should be a 1/8 wide bead

A head gasket sealer works when you pour it into the radiator. You run the car for about 15 to 30 minutes, with the heater and fan on high. Then the special chemicals in the sealant work via heat Generally, if its two cast metal pieces going together, a sealer is not necessary, even if you are using old style cork or paper gaskets. These old style gaskets only need sealing if you are installing a stamped steel part, like an oil pan or valve cover Whether it is the automobile industry, manufacturing, or power generation, the need for high-performing and reliable gasketing sealant materials to keep processes running smoothly is essential.Leaks or unintended fluid intrusion lead to downtime, work stoppages, and increased cost. However, high-quality gasketing sealant materials prevent leakage or the intrusion of fluids or gases by.
Another sign it's time to replace your water pump is one you might see beneath your car. A coolant leak under your engine could indicate a blown water-pump gasket. That means there's damage to the thin piece of material that helps make a seal between individual metal parts of the pump. Without a good seal, the coolant can drip out BEFORE opening a pool pump to replace a seal be sure to inspect all other components of the pump for leaks. The seal is the most difficult leaking pool pump repair and should be attempted as a last resort. Leaks from manifold cracks, threaded connections and loose winterization plugs can all leak. The source of the water can be difficult to locate O-rings, gaskets, and seals protect your pool parts from water damage. This is why we always recommend replacing your pump shaft seal whenever you replace your pump motor. Whenever you need to replace your pump seal, make sure you have the make and model number of the pump handy Mechanical Seals are not all we do. Not all pumps require mechanical seals. In some cases a braided packing can prove to be less expensive to run and can solve some problems a mechanical seals just can't. While mechanical pump seals generally seal along the seal faces, braided packing seals along the shaft sleeve and the stuffing box walls It permanently repairs leaks in the head gasket, block, radiator, heater core, freeze plug and water pump casing. Trusted by professional mechanics, technicians and motorists alike, K-Seal is suitable for use with all water cooled engines including cars, motorbikes, commercial vehicles and heavy machinery Gaskets are not intended to nor do they need to swell to do their job (at least not in 450 Honda engines) Honda gaskets sometimes have a bead of some kind of sealant built right into them, the gasket between the cases and the right and left side covers are as such
