I have a '95 GMC Sonoma 2.2L that's getting hot. The temp gauge only goes to about 210. But smoke is coming into the car through the heater. I thought it was the thermostat because I smell that radiator smell, but obviously that's not it. Any suggestions?

Truck: 2001 Ex-cab 2wd s-10 Drivetrain: 4.3 V6 with Auto trans I seem to have a coolant leak somewheres. It comes from the back of the motor. When the coolant level gets low enough the leak seems to stop, as well as the heater. When I fill the coolant back up, I can park the truck and after a few minutes (a run into the gas station to pay is long enough), I come back and it is dripping from the back of the motor at a pretty good rate. When I run the heater, I dont get any odd smells into the cabin, but the heater will quit working once the coolant level gets low enough. I also do not have oil int he coolant or coolant in the oil. No smoking out the back of the tail pipe. The truck runs just fine. The only time it goes wonky is when the coolant level gets low. When the coolant is full, the temp gauge runs just below halfway (210 I think) and stays there. It also gets there quite quickly and always has. I know there is a couple of different places the leak could be, but I was wondering if there is a most likely culprit.

I have a 2002 S-10, 4.3, A/T. I just change the thermostat to a 195 deg. The operating temp now stays at 210 deg.( mid range on the gage ). My question is will this be detrimental to the life of the engine, will I see any difference in mpg, any adverse effects in warmer outside temps? I live in Phx. Ariz. so the temps can get quite hot in the summer months. What is the recommended operating water temp? Thanks for any help.

Replying to: jetjunky (Nov 08, 2009 9:55 am) You won't see any damage if the temps stay at 210. What you do need to worry about is that in the summer, you might see the temp range in the higher side rather than the low side because of the 195 degree t-stat. That is something that I would be careful of. Instead of operating between 100 and 210, you are now operating between 210 and 260, which can get dangerous on hot days. Especially in rush hour traffic traveling at only 10 MPH. In my opinion, I would switch back to the standard factory t-stat. Is there a reason you went to the 195 degree one? People make all sorts of claims pertaining to running one, but I haven't tested it to be sure and so I don't know. They all sound like hocus pocus to me. |
