Where is the thermostat in a 1999 Pontiac Grand Prix 3.8L V6
I need to Locate the Thermostat on my 1999 Grand Prix, It is over heating suddenly & I was wondering if I could start with a possibly a cheaper fix than taking it in for diagnostics & a new water pump, which is something I couldn't do myself. Out of the blue on the 1st 80 degree day my car over heated and died after a 40-45 min. ride with an abnormal amount of idling due to wonderful construction. I have driven it to & from work twice since then, a 20-30 min. ride. It did not die but it was quite over heated by the time I got home.
