Overheat

[bsr2002]

I'm driving on freeway about 30 miles from home everything is fine, when I get off ramp and stop at the light I notice my temp gage moves up like it wants to overheat...When I get back on the freeway ti goes back down.

Thermostat maybe???

I would be happy to look into this further for you. In order to do so, I will need the VIN for the vehicle as well as the current mileage. Please feel free to contact me via private message if you would like. I look forward to hearing from you. Thank you.

Yes radiator level is good, and yes I can feel the fans kick in...Maybe a clog somewhere???

Why do you need the VIN#? Seems everyone of ur posts requires one.

Seems to me all u would need is year and engine and symptom

are you able to check the radiator level...or just the over flow tank?

Because she's running a VIN-based check of recalls and service bulletins.

I heard GM was going to monitor web sites for "problems" with GM vehicles. We'll see how long that lasts. I'm going to have to check pistonslap.com to see whether anything useful has happened there...

where are you seeing the oil??in the radiator?
oil in radiator will normally be trans oil,from a bad oil cooler
antifreeze in engine oil normally head gasket
have'nt heard of intake failure for this on the 3.1l engine
like we are seeing on 3.8 & 4.3
how many miles on the engine?
is this the 1st time you had over heating troubles?

I'm seeing oil or dark stuff in the radiator.

No over heating problems till 2 days ago.

Not good, either a bad lower intake gasket or blowed head gasket.

Usually oil in the radiator and overheating would indicate head gasket depending where the gasket is leaking. Not sure if LIM will get oil in the radiator or not.

Or a cracked casting.

Head cracks are common on the 3.1/3.4. Hell, head cracks are getting to be more common on pretty much EVERYTHING. The wall thicknesses are reduced for weight savings; and the strength/durability goes away with every ounce saved.

Checked the oil and trans fluid and both levels are good. And no discoloration. However when I take the radiator cap off I have what looks like sludge. I guess intake or best case senario clogged radiator???
