    Water pump gasket verses Rtv sealant

    What's the opinion on installing water pump with gasket only, gasket with combo of Rtv or another sealer, or just Rtv or another sealant??? I just replaced my water pump on jeep 4.0 and didn't do a good job because the gasket is leaking so I want to make sure I do this right the second time around. I only used the gasket that came with the pump, surface was cleaned but in thinking I went wrong and possibly over torqued it. Would love to hear everybody's opinion on the best route to take on the reinstall.

    It says on the can. I do it on both sides of the gasket depending on what I'm doing

    Is that pretty much the same stuff as Permatex 3, or am I missing out on something?

    Last few water pumps I have done I used the regular permatex grey gasket maker. Make sure you are not over doing it on silicone, you want a really thin coat all the way on the block as well as the water pump. Thanks for sharing the gasgacinch guys, I will give that a try. Best stuff I ever used came from the Ford dealership my Dad was working at, now I just use the regular grey stuff at Autozone and have no leaks so far.

    I 2nd ditching the gasket and just using RTV. Use it sparingly but get it completely covered on both sides. You should be good to go.

    My last one I went through 2 gaskets and after wasting a bunch of coolant, the RTV finally got things sealled up.

    damn near any silicon will do the job if prepped right, you dont wanna over do it and have ropes in your coolant, like others said a light film all the way around the surface. basically filling all the voids, pits, and low spots. i assembled my entire toyota case (6 different mating surfaces including the adapter) with a tube of victor reinz vj8 engine silicone and i dont have a drop out of them. thats about all i use at work as well

    ANY gasket sealer will work on this application as long as you use your head. If you glob the crap on there as thick as possible, you are going to have issues. A thin schmear is all that is required to dress a gasket.

    Do not ditch the gasket. It is there for a reason and it will by far outlast any rubberized goo you place between your parts. If you want to do it right the first time, here are a few tips.

    Lightly apply said goo to both sides of gasket

    install part with gasket and lightly , note lightly here...., torque the fasteners

    Go have lunch, play a few video games, or drink a few beers if your old enough to give the goo time to set. Personally, i allow it to set overnight, but that is just me. If you dont let it set, you run the risk of the gasket slipping and not sealing correctly

    after is has set, torque the fasteners to their required torque.


    As for goo of choice, coming form a dirt bike background, i've always used Hylomar non hardening anaerobic sealer. Expensive, but this stuff works and any waste will not clog crap in your engine. My second go to goo is Loktite 518, cheaper than Hylomar, but just as good in some applicaions

    Wow lots of options here My 2 cents worth.. The first thing no matter what you use you MUST have a clean surface to work on ie grease,oil,dirt,water,chemical free surface that includes the gasket as well as your fingers. I use brake cleaner (NOT Carb cleaner it leaves a chemical resadue) to clean everything including my fingers. Then I will apply a small dab on my finger and apply a thin film to the metal pice where the gasket goes, do the same to the other side. Tighten bolts or nuts to manufacture specs, DON'T OVER TORK. If you can let it sit overnight do so if not wait as log as you can before exposing it to fluids or heat. I use ULTRA BLACK for all my builds, the stuff is amazing I have stopped oil leaks on a cracked oil pan with this stuff.

    I don't use gaskets for anything unless the gasket thickness is critical for clearances. I use copper RTV for everything and call it good.

    Clean surfaces, lightly coat to both surfaces with RTV, lightly assemble parts, let set 30min+, torque to spec.

    I you have true surfaces, Stay away from silicon as much as possible. If you ever have to do it again, silicon makes for a hard clean up. If tour surfaces are all pitted or have obvious low spots you can use silicon sparingly. I like to apply it to my finger(Not the parts) then firmly slide my finger across the surface to apply just enough to fill in such voids. The pump it's self should be nice and true as it is new. DO NOT use silicon on the pump side of the gasket. If you feel it necessary apply some Gasgasinch to the pump and pump side of gasket, let dry, and then stick gasket to pump. Even this is not necessary but it does keep the gasket in place so it does not slip or bend during installation. I have been doing things this way for years and have NEVER had a comeback for a leaking gasket that I have installed. In all actuality there is no need for anything but a dry gasket if your surfaces are true and clean. The material in the gasket slightly compresses and then the side that touches liquid slightly swells as the liquid absorbs into it. This slight swelling( and I'm talking maybe 100,000th of an inch here so don't go telling me how you have never seen it) creates the seal. If you do need silicon, remember this. If you see it squish out of the side of the gasket while torquing the part down, you have used to much. The bead you see around the outside will be the same size on the inside and you do not want that bead breaking loose and traveling through your system. It can clog passages, hold the Tstat open, or even destroy your pump if it gets caught up in the impeller.
    Hard work good, Hard work fine, But first take care of head! Knowledge is everything!

    it will definatlely seal, but, we have a rule of thumb at work, "if you don't want it leaking OR COMING OFF, use right stuff".............its almost 'too good' for some things..........yes, I've used right stuff on water pumps....just not mine
