ok so my 02 Trans Am is having troubles getting to operating temps and then overheating. i installed a Prosport coolant temp gauge in the passenger side head to help monitor. the prosport gauge is staying around 140* and will only get to operating temp in city type traffic, which then it gets close to 240-250*. the factory gauge stays right about 160 never reaches 210 unless in the city. never stays at 190-210

i put new heads on a couple months ago and it has been doing it ever since then. i had one leak at the heater hose/waterpump connection which i fixed.

im thinking a possible stuck open t-stat but not sure. thoughts?

FYI its a H/C car. id like to figure this out before we get into more tuning.

thanks in advance!!

Looks like your running just fine, factory gauge might not be accurate but its showing you a normal range of temps while driving.

Looks like your Prosport is bad.

thanks LS6427 that is a good thought. ill have to call prosport and see if they have any way for me to check out the sending unit and/or guage
