bigredhdt Posted December 21, 2021 Report Share Posted December 21, 2021 Anyone change a d12d water pump? Got a leak on the flange of the pipe that goes from top of the engine to the water pump housing. Cleaned both surfaces very well and used a new metal gasket that came with the pump kit. Wondering if I should have used some water pump housing silicone on the metal gasket? Quote Link to comment Share on other sites More sharing options...
bigredhdt Posted May 25, 2022 Author Report Share Posted May 25, 2022 Took it to a shop and they told me silicon is needed. Let them do the work and no more leaks. Quote Link to comment Share on other sites More sharing options...
rickeieio Posted May 25, 2022 Report Share Posted May 25, 2022 Success!! Generally, I use a very thin film of sealant on most types gaskets. Type of sealant depends on gasket material and application. I rarely use silicone. Rule of thumb, if sealant squeezes out, you used too much. Imagine how much also squeezed "in".

Parrformance Posted May 25, 2022 Report Share Posted May 25, 2022 I have had an engine run cold, never warm up, because I had a Shop do the pump. When I pulled the thermostat out there was a glob of silicone caught in the thermostat keeping it open.
