3800 engine temps

[Toasty]

OK. now that my GP cooling is under control, my regal GS starts acting up..

in heavy traffic a few weeks ago, i noticed the temp gauge creeping up, but once i was in the open, it seemed fine (low 80's-mid 90's temps) it's been fine for 2 weeks, stop and go warm/cold etc. today, while idling at the mall (waiting for wife) the temp creeped waaay up again. drove around, letting heat into the car, temp went back to just under half (about normal, no temp reading on gauge in the GS) temp didnt really move from that spot no mater what i was doing, hot cold air inside, stop or go, but maybe did creep up a tick on the gauge when sitting at a long light.

the engine cooling fans seem to be working... i havent noticed coolant dripping from any weep hole in the water pump....


can someone help?

t-stat sticking?

You running the A/C?? That will cause your temps to go pretty high. No A/C on I usually stay around 180ish. With A/C on and traffic I can see 220ish.

Put the AC to max and see if BOTH fans are working on the radiator.........most likely a simple Tstat swap though.

anybody have an idea of what the actual temp markers on a GS equate to? no numbers on the face

i've been trying a few different things, temp to 90 on vent, off, etc. and it hasnt been really consistent.

both fans were spinning when i looked.

I was cruizing, and saw ron v out in his driveway, stopped to confer with him a minute or two, gonna start with the t-stat and a good coolant flush....

thanks for the suggestions fellas, and thanks Ron V.


now just need to find a place to do the flush... not set up to do it here at home....


hmmmmmm

I have a 180* t stat in my Regal, and I never pass halfway with the a/c off, no matter what driving, idling I'm doing. With the A/C on, I may get to half way, but never much if at all past it. I have original radiator, never cleaned, relatively fresh dexcrap, and DHP fan turn on points.

I'd say straight up and down is 195-200*..

you could always find someone with a LS1M, or autotap, and scan your pcm for the coolant temp. the computer will have a digital readout of it, and that way you know where the cluster is at....even though it is not marked.

ouch... that hurt!


said screw it and blew 90 bux to have the cooling system flushed.

not so bad, i suppose.

also changed out the thermostat. hopefully that will take care of it, though.
