I just changed out my thermostat on my 454 I did as best I could with what I had. It was leaking slowly but the thermostat itself works I just changed it a couple of months ago. So what I did was just pull it out put more silicone on it and that's it. I didn't have any sandpaper or anything to scrape the surface so I did my best with a screwdriver. My question is if I let it dry for around 2 hours will it hold up for today? I am not gonna take it wheelin just going to an off road race then fishing. what do you think? I plan on changing everything out tomorrow.
