Thermostat Install DIY
Ok I did my 195 to 180 thermostat today along with the coolant flush, GMB Water pump, and Gatorback belt.
180 thermostat - Napa #530080 (needs modifying)
Coolant - Prestone Dex cool
GMB water pump - #120-4350
Good Year Gatorback Belt - #4060875
Ok so ever since I have been a member people have always wondered which way the thermostat goes, and what the heck is the notch that people are talking about. And how you need to modify the much cheaper Napa thermostat that does not have a notch. Here are the pics!
First things first. My pictures are taken from the top of the engine looking down.
To remove the thermostat cover required a 8mm socket (2 bolts)
