Why didnt ya just use sealant?

They make universal rolls of the blue gasket stuff too.

RTV....never cork.

 

[F 150Cobra]

i use cork and the RTV silicone stuff.. becuase i dunno if rtv silicone would work alone

 

[Truckin4life]

rtv alone works...

 

[F 150Cobra]

rtv alone works...

thanks.. now i know... hope the new waterpump comes with gaskets ottherwise im gonna use rtv

 

[Truckin4life]

new pump should, no store in town stocks them? Or they just out of stock?

If it comes w/ gaskets.....throw them away. It'll leak.
This is 15-20 water pump install history(back to the '70s).
I'm just trying to stop an issue down the road.

What I do is do sealant on each side of the gasket and Ive never had a leak.

I haven't had a problem with the gaskets that come with water pumps and I've done alot of waterpumps on many different cars.

Same here...I do a thin layer on each side of the gasket and a thin layer on the pump...never had an issue.

 

[flareside_thunder]

I do this stuff on all my paper gaskets and never had an issue!

 

[surewhynot]

Same here Jr.

 

[Truckin4life]

Never used the spray copper... Might have to try it... Always done the rtv on the mating surfaces though like some on the pump, stick on the gasket then some on the block... good to go... Only use it on paper gaskets though, i think it messes with the cork gaskets...

me 2.. but never had problems before..untill now i used Cork gaskets...

I have cork valve cover gaskets and I do it that way with em and no problem.

I have to wonder how you think the cork did not go into the water jackets or radiator if it was shredded in the pump and stuck to the timing cover.

Here's my favorite gasket goo. This stuff stays soft, always tacky, and coolant will NOT affect it. Acetone (nail polish remover) removes it quite easily. It's about the only thing I've found that will stop a VW from marking it's territory.

I had to redo the timing cover and water pump gaskets on my blue bird after a dealership totally botched a long-block install. In less than 5000 miles, coolant was coming out faster than I could put it back in. Warranty? Umm, GASKETS aren't covered, and neither is the labor to install them. Gaskets are considered a "maintenance" item.

If I need something to set a bit harder, then this is what I use:

This stuff is good on trannies where there isn't nearly as much heat variation and problems with metal expanding/contracting constantly, or at different rates (cast iron vs aluminum).

Bottom line, I NEVER EVER put a gasket on without some sort of sealer applied to it. I NEVER use silicone (RTV) on an engine. Get one little bead of RTV in the right place, and you just toasted an engine. If HyTack won't seal it, or Indian Head, it can't be sealed, or it needs the sealing surfaces machined. The HyTack can be layered on a few times to make it nice and thick too. HyTack does not make beads when it squeezes out either, like RTV. Instead, it spreads along the seam it is squeezing out of, and forms a seal from the inside out.

But, you're right, NEVER use cork on coolant systems. The cork actually absorbs the coolant, and swells. This makes it turn the rubber binder loose and fall apart. Cork gaskets are good for things like valve covers, dif covers, or anything that can't be precisely matched like the front and back edges of the intake. Use the paper ones if it's going between two machined surfaces, though. I've used playing cards to make them for small engine repairs (lawn mower, etc.) when I was in a bind, or bringing one back to life that I didn't know whether or not it was worth spending any money on. Even that got a good dose of HyTack, though. Cork gaskets are typically intended for sealing two items that cannot be torqued down tight. Your water pump can, and should be, according to spec.

This is what I use.

Its kinda hard to get back off but if ya have a good quality scraper or wire wheel either on a drill or a bench grinder it comes right off. I use it on everything and I have the one that comes with its own little caulking gun to make it easier to use. The cans always run out about halfway when all the gas escapes. They have it at any auto parts store. Ive also used that stuff alone on water pumps and it holds just as good as a gasket. Theres also no fumes like silicone has and it dries quicker. I spread it out on the part with either my finger or a pop cicle stick so it dont pooch out the sides.
