Engine Performance problem
2006 Chevy Colorado 4 cyl Two Wheel Drive Manual 50,000 miles

I just bought a thermostat and need some advice to how to get to it because it is deep on the engine in the left side. Should I go from the top, or the bottom or the side? Also should I disconnect the battery?

Do you
have the same problem?
