#37 of 188 Tempuerature Gauge rises when Air is turned on
Jun 08, 2007 (9:17 pm)
I have had a Flawless 2001 2WD Chevy Blazer 2 Door 4.3. Recently like a clock work I had Fuel Pump and most recently Intake Manifold Gasket go bad and truly a mayor Labor intensive job due to top engine parts disassembly.
After the fact I have noticed my temperature rise after turning the Air conditioner on, when idle or stuck in traffic.
Hopefully someone may have some idea of what could cause this. I love my Chevy, is been good to me and is still looks new at 118,000 miles!
Any comments will be greatly appreciated.

The air conditioner will put an extra load on the engine and may cause it to heat up. The fact that your engine gets hotter while idling suggests that you may want to replace your (radiator) thermostat.

The thermostat should have been done with the intake and get a new radiator cap - Stant one. With these done and the coolant 50% Dex, the temp should be running at 195 and never go over 210 (gage dial straight up). If it does make sure the water pump is good (no leaks) and the fan clutch works (good sign of this is when hot and has sat alittle while and you start it you will hear the fan lock up and push lots of air - if it totally free wheels when hot it trash).

Thanks. I am going to flush Radiator and make sure I refill with 50% Dex. Mostly it stays withing those parameters but when I get into traffic the arrow goes past the 210 and I turn the air conditioner off to be save. But I am now in the right track thanks to the advise. Highly appreciate it.

Yes, only one under the upper rad hose on the intake.

Get the new cap and see if thats it and save yourself some work - most shops can figure 50% (I hope).

This definitely helped some. The gauge does not go as far right past the center as before. Now I have to assure on two points that members recomended! Like the Water Pump leak and the Clutch Fan.

My Air conditioner works fine only on high blow. What could be the possibilities here based on past experiences. Any comments will be appreciated.
