I’m trying to change the thermostat on the my 2003 Buick Lesabre custom. I try to put it on multiple times but it is still leaking. What can be do differently?
Answer: Well, I put them on all the time and don’t have problems with them. Make sure that you clean the housing off really well with a scraper, and be careful not to gouge the housing. Then put the gasket on and torque to specs.
