January 3, 2005Hello all, well just a few days ago my brother went and bought a 1997 GMC Serria with a 6.5 Turbo, and it has 250,000km on it but it has a brand new crate motor in it about 50,000km ago, GM Goodrich Installed. Well anyways my questions are why does it not warm up very good?, we put new thermostats in it, found out the old ones were in backwards, and we also found out that the clutches in the fan are SCREWED. The fan has movement in it. Could the fan be sticking wide open and causin the truck to run cold? Please Help!
