22071 Water Pump and Thermostat RTV Silicone Gasket, 0.5 oz.

Works great, no leaks. Install per instructions and you'll be worry free.

good as exprcted from permatex

Worked like a charm. You have to follow the instructions to the letter or you will have a leak on your new pump. 1 hour finger tight on the bolts and then be patient and wait the full 24 hours after torque on the bolts before refilling the system.

If your a mechanic you know that most water pump failures come from a leaking gasket and many water pump kits come with terrible paper gaskets you have to fight to get centered when putting them on (early 2000s mercury mountaineers come with like 14 bolts). Take out two birds with one stone. Small bead of this--bloop, paper gasket on--pat and bolts in. No more dreaded leaks and replacing aftermarket pumps 3 times in the span of a couple years and no dreaded headache installing a simple water pump. Get your shop to buy a tube of this every waterpump replacement, put it on parts for the customer and your doing them a service.

This tube is relatively small. Other reviews said the same thing, but you have to see it for yourself. It's enough to do one housing, maybe two.

Absolutely go to water pump or thermostat housing sealant Good stuff that works! Outlasts the parts....

Worked well for water pump gaskets

Perfect size for 1 time use

worked on replacing water pump with no leaks

Left a drop on paper to see how long it takes to vulcanize at room temperature. It has been 18 hrs and this stuff (whatever it is) is still greasy and sticks to fingers ! This is not not I wanted. Very bad product. I need the seller intervention to verify what he has given me is genuine from USA OR a rejected item.

ウォターポンプ取替えに最適です本当に良い

I have used Permatex for decades . It has never failed me .

Very good silicone for antifreeze!
