The car temp at idle is little lower that 185, when I went for short cruising it raised up a little as shown in pic 2.

After I turned on the AC , It moved to 210 , and after that it reached above 235.

Is this normal ?

What's the normal temperature of the LT1 ?

Both fans should be running when the AC is on. Are they?

Shouldn't make any difference while going down the road 60MPH. I don't think the fans even run when you're going over 40MPH.My car will run COOLER in slow traffic with the A/C on because it makes both fans run. If yours runs hotter with the A/C on, I'd make sure the fans aren't wired backwards where they're trying to push air back out the front of the car. An LTx should almost always run cooler with the A/C fans running.

I have a 1995, in a parade with air temp around 85 deg running the air conditioner my electronic temp indicated 200 to 205 degrees.

Agree. Your results are exactly the reverse of what should happen. Only if you lived in Australia where everything is upside-down would it be normal.

BTW you will get a much more accurate reading if you punch the "gauges" button on the dash until you see "cool" and a numerical temp on the digital display.

Where were MPH mentioned? OP is showing outside temps of almost 100 degrees, if he's cruising around town with the AC on and only one fan is working his temps will rise, hence the question, are BOTH fans working?

I really have no idea why I didn't think about this !!




Will be checking that also




I'm laughing at myself now , I remember seeing that
but I didn't know that I can see the temp in the digital display. I don't touch the buttons often. lol

Mohammed_z

So what's the normal temperature ? 200-205 ?

The LT1 was designed to run between 200 and 230. If I remember right the fans don't come on until 228. Also, bear in mind that the analog temp gauge is not linear, your temperature was probably not as high as you think it was.

The primary fan comes on at 228. The secondary fan(passenger side) comes on at 236, I believe. It's true that the electronic is a more accurate reading.

these cars will sit in traffic at 225.. hit the on ramp and BAM 190.

ive gone up to 235 on a hot day and was told to not worry.

I was told the same thing for my L98. This weekend, sitting in traffic waiting to get into a show, my car hit 220 for the first time this year. It worried me for a second, then I heard the fan come on and the temp gradually went down to 194 before it turned off leaving the aux fan running (that one is wired to come on first at a lower temp).

This gives me some peace of mind , but I'll check the fans and digital reading just to make sure.

My fan kicks at 225

Mohammed....have you ever removed the radiator and cleaned off the front of it? C4's are "road vacuums" and pick up every possible piece of debris, and guess where it gets stuck? On my old 84 I found a plastic bag, cigarette butts, feathers, leaves, you name it. Cleaned and reinstalled, car ran 10-15 degrees cooler.

Your temps aren't really bad for where you live. I've seen 235 on Marco as well before it started to come down.

Klondike

Oh yeah, Forgot about the old grass in the radiator gig. Time to empty the C4 vacuum cleaner bag!

Ok I am from Australia, you made my day. I had a good laugh.

Back to the thread, I will note what my L98 runs at during hot days in Australia. Mine is in the middle of an engine freshen up.

I believe the passengers on the Costa Concordia were told not to worry as well.

Here's mine. Runs way cooler after cleaning
