SSAlaska Posted September 8, 2004 Report Share Posted September 8, 2004 I live in Anchorage, Alaska the temperature never gets above 75 degrees here. My truck always runs at 210 degrees whether I am in traffic at a stop or crusing at 75 on the highway. This weekend I was crusing at 75 MPH in 22 degree weather and I still was running at 210. Is this normal? I am seriously thinking about getting a 160 degree stat. Do I need one? Help me out here fellas, Please. Link to comment Share on other sites More sharing options...
dcairns Posted September 8, 2004 Report Share Posted September 8, 2004 The in dash gauge is not all that accurate. It seems to enjoy parking around 210. Looking with my puter and EFI Live, I can seem more change in the coolant temps than is reflected on the in dash gauge. But, keep in mind, the engine is designed to run at that coolant temp. Lowering the thermostat temp can have indesired side effects. Link to comment Share on other sites More sharing options...

BenKey Posted September 9, 2004 Report Share Posted September 9, 2004 If I ran 210 all the time, no matter what, I'd begin to believe my gauge wasn't working correctly. I would take it to the dealer and let them hook a tech II up to it and really see what temp it's running at. If it's way off, although not sure where the cutoff would be, it would seem like they would send off for a new gauge cluster. I have a 160 stat and run at 183 in 90+ heat - as monitored by EFI live. At idle it will come up until my fans come on, then back down. FYI, my gauge reads about 8 degrees off, but the diff is not linear. Link to comment Share on other sites More sharing options...
m396 #00-011 Posted September 9, 2004 Report Share Posted September 9, 2004 Without electric fans, pretty much regardless of thermostat, the truck is going to run the temp it wants. I don't believe there is a adj temp sensor for the clutch fan. A thermostat only effects the temp at which the coolant circulates, it's not really much of a control measure.

vette dude Posted September 9, 2004 Report Share Posted September 9, 2004 w/160* stat and electric fans i never saw below 210.. with the stock fan and 160 stat If i run the truck at 80-98 It starts to get hot like 220-230.... Link to comment Share on other sites More sharing options...
BenKey Posted September 9, 2004 Report Share Posted September 9, 2004 I never saw above 200 with stock t-stat and clutch fan - in 90+ heat. Link to comment Share on other sites More sharing options...
zippy Posted September 9, 2004 Report Share Posted September 9, 2004 put in a 160 stat and water wetter and see if it does what you'd like it to. with a stock fan and 160 stat it should run between 172 and 180. Link to comment Share on other sites More sharing options...
