The mating surfaces of the aluminum thermostat housing on my '86 S-15 truck have become pitted and otherwise distorted. The regular gasket does not provide enough seal, but so far this stuff has. I'm very pleased and would recommend it for such situations as mine.

Replacing old thermostat, bought this gasket and silicone as well as O-ring. After removing housing, found that previous (factory) installation had only used O-ring, no gasket or silicone. I decided to follow that example in installing replacement, and used O-ring only, returning gasket and silicone to store. Seems to be working fine so far, no leaks.

    Comments about Permatex Water Pump And Thermostat RTV Silicone Gasket (.5 oz):

    I was highly doubtful this product would work. I had used rtv 30 years ago and it failed. After reading all these reviews, I thought-maybe I'll give it a try. Can't believe it worked. I used it to seal water pump and T-stat housing on my Nissan after replacing water pump. I lightly applied to both surfaces (instructions say to only do one side),assemble parts but did not torque. Waited one hour as instructed then torqued down. I waited 24 hours, as instructed, then pressure tested cooling system. IT WORKED-NO PRESSURE LOSS!! The key to using this product is make sure parts are meticulously clean and follow instructions making sure you wait 24 hrs for sealant to dry.

          I no longer use paper gaskets for waterpumps, thermostat covers, or anything that comes into contact with radiator fluids. This stuff has worked 100% of the time I have used it.

          For proper application you must make sure all old gasket material is removed and cleaned with a wire brush or other abrasive scrubber. Make sure all oil/coolant is free from the gasket surface too. I use rubbing alcohol and clean paper towels for the final surface clean. Apply a thin 1/16'' on both mating surfaces and allow to dry for at least a few hours or overnight if you can. Wear disposible gloves for application for easy cleanup.

                      I did not wait at all and filled my radiator up immediately after using this, saw that it was leaking and emptied the whole thing again. Is it worth it to let it cure overnight now? Or should I just scrape it off and start over?

                        Hi, it is always recommended to use gasket instead of using silicone gasket. I researched and I am unable to locate a pipe gasket for thermostat hose for your Ford Ranger online.

                      • A:

                        probably shouldn't. If a water pump starts to leak, there's likely something internal that's breaking down - bushing/bearing/seal of some kind. Usually, you'll notice a leak out of the bottom drain hole - don't plug that hole, it's supposed to be open.
