What is normal operating temperature?

[Slaytanic-666]

219 degrees F. or 90 degrees C. ? My temp gauge was reading about 225 at the high end...The PO had installed(an after market it has degree intervals on it) this gauge because the cluster gauge went...I'm sure it may be the si batteries...I have yet to get in there and replace the service interval batteries....

219 F does NOT equal 90 deg C.

Your car should be at or around 190-200 deg F on the open road, 210-220 deg F in heavy traffic in the summer.

Hmmm maybe this gauge sucks, from what I can tell from in heavy highway driving(passing cars hard hills) today it went up to 225 F and was starting to arc past that...but stopped...and thanks Jeremy for the info.

I can tell you for a fact my car never runs that hot even in the Texas summer with the AC on. Like Jeremy said its somewhere between 180 and 210 degrees depending on operating conditions.

Thank you...you could say I'm kinda of concerned....

Maybe the gauge is reading inaccurately. There are other ways to tell if the engine is running too hot. Mostly smell. Do you smell anti-freeze? Cooked oil? Is the car using coolant?

[Slaytanic-666]

Heh yes I started a new thread because I just found a milky substance on my oil filler cap about an hour ago... coolant on inside of windshield heater core loss. No real smell inside passenger compartment, coolant loss out top of reservoir. I will keep you guys posted thanx man

1st:
Explain this.

coolant on inside of windshield heater core loss.

2nd:

coolant loss out top of reservoir.

There is a kit you can buy that adds a chemical to your coolant that will change colors if exhaust gas interacts with it, telling you the condition of the head gasket, or a shop should be able to do it for you.

In the morning there seems to be a film on the window and I have squeeged the inside of the windshield clean with soap and water it was spotless...it was all gone, it seems to coming from the def vents up front. I still don't smell any coolant, nor do I remember smelling any, ever, in the passenger compartment. My buddy has all the tools for leak down, pressure testing, infra red temp gauge, all the equip needed to test anything thanx I have been keeping him updated...
