The last two evenings,after driving about 15 miles to work,parking,then sitting/idling with the heat on about halfway for close to 15 minutes,I've noticed the temp gauge creeping up to the 190 to 200 degree range after running around 160 beforehand.

I don't recall seeing this before,but I certainly think I would have if it was a regular thing...as this is a fairly regular routine for me.

Anyway...does this raise any other eyebrows other than my own?.

Thanx

It should be at 195, running at 160 seems very low. Im surprised it hasnt set a P0128 code running that cold.

Obviously, checking the coolant level is the first thing to do. Then check to see if the electric fans are running when the car gets hot. When the car is not moving, this is the only source of cooling air through the radiator. Also, check to see if the airflow through your radiator is restricted. Look for debris (leaves, dirt, etc) on the front, which will block air flow. I've seen plastic shopping bags sucked up into the radiator many times.

I'd be more concerned with why your car is running at 160, as it's supposed to run 190-200. Check your thermostat. GARY

I'm pretty sure it was around 160 while driving...certainly could be mistaken,but I will watch it like a hawk while going to work this evening.

Thanx for the quick replies.

If it warms up to 195 when idling or in traffic and runs cold when moving in clean air, I bet the thermostat is stuck open.

I'll place five chips on the thermostat being stuck open.
Raise that coolant temperature into the normal range and your MPG will also increase.

The car was running at about 155 while driving...a lil' stop n go,and not for very long at all...only about 5 lights in a couple miles...the last 15 miles,if that,is at highway speed.
Outside temp has been around 50ish here in lovely Richmond,Va.

I'm sitting on a brand new 180 t-stat from ZSPOT...so,I guess that I'll drop that in this weekend,regardless. Wink

? Are the fans supposed to run in conjunction,or are they "independent ?
I popped the hood two separate times after parking / idling and I'm pretty sure I only caught one running,and that one did cut off at least once each time.

Thanx for the replies Smile

Pretty sure the fans run independently. Not sure if the second one kicks on if the temperature exceeds a certain number, or if they alternate, or what.

The first fan will turn on at a certain temp and the second one will turn on (while the first one stays on) at a higher temperature. I don't know what temps they are exactly, but I know one is like 25-30* warmer than the other.

Iffy is right. My DHP stuff is on the other laptop so I can't look up exact numbers but I believe one kicks on around 195* and then the second at 215* or something around there
