Anyone have a referral for a GM mechanic for an overheating 2011 Cadillac with 80k miles?

Not familiar with DFW,   but a radiator shop or car care center can pressure test.    Just check their rep on Yelp,  Google, etc.  If it is a major issue,  may be best to seek more qualified mechanic.

Also,   cooling system probably needs to be flushed if  not recent.

Flush is probably recommended at 100k. I’d check the radiator cap, it’s probably just on the reservoir. Might grab the water pump and see if you can move the pulley side to side. Bearing might be going out.

Check the fan. Is it just getting hot at low speeds or idle?

PM ernest t bass.  He's got a great Ford dealer.

Be careful with flushing as the sediment that is created over the years plugs small leaks in the cooling system. Seen many a time folks flush their cooling system to have a heater core start leaking. If you do decide to fly make sure distilled water is used.

Any change in color of the antifreeze?

Earlier this week, I noticed the electric fan running when I shut the engine off.  That's odd for this car and it hasn't been that hot.

Earlier on this drive, I noticed the temp gage bumping above 220 momentarily. Google Maps left me on the toll road in slow traffic with no exits and I looked down and the temp was way high.  I turned off the AC, turned on the heat full blast, temp dropped rapidly but it went to "ENGINE REDUCED POWER" and I made it home.  Haven't looked at it since.

Could be something simple like coolant flush, or possibly even low coolant, but that fan misbehavior? bothers me.

Elaborating.  The small bumps above 220 were on a CR after being on the highway, so slow after fast.  Then the big meltdown was several miles at 20 or under (thanks a lot google).  So I am kind of leaning toward electric fan.  Are they just thermostat controlled anymore or have some kind of ethernet/wifi connection to Skynet these days.  I don't relish mucking around in the tiny engine compartment either.

Check engine light on? Have you pulled the codes on the cars computer?

[Jkwellborn 6898]

Check the coolant level first. It’s the cheapest and easiest thing. Check the fuse and connections for the fan from there.


Whatever you do, don’t take it to the Chevy dealer that earnest did.

The electric fan could have constant power when the temp gets past a certain point. I’m not sure though.

check coolant level in reservoir. we had to replace both tee fittings on a yukon which had a slow leak.

[gyroprotagonist 2595]

had something similar on my 08 tundra.  it was a coolant leak and the shop said it was leaking from the water pump. 

[Jkwellborn 6898]

Here are some plastic fittings that connect to the firewall and intake on a lot of vehicles that will leak after they start getting hot and brittle.

Thanksl Water pump.  $600 with labor, not too bad.

[strangulation! 1716]

every time i go there the cost seems reasonable.

I’m always happy with Dennis Road Automotive.

[TwiceHorn 31707]

I'll keep them in mind also.  For further reference, Marlow Automotive on Central up Richardson/Plano way is a pretty good shop, too, especially for older vehicles and Jeeps.  I was wary of driving that far for fear of overheating.

[Spur08 382]

@TwiceHorn  I have a mobile mechanic who is the shit and very reasonable.  If he buys the parts for you, he'll transfer his cost to you.  I usually buy my stuff off RockAuto before he comes out and he has no problem with it.  If anything sucks about him, it's that he can be tardy if you schedule late appointments.  I usually go for the early morning on the days I work from home.

Cool, thanks.  I will bear that in mind also.  I guess he brings his own ramps and stuff?

Yea, he brings a truck similar to what a plumber or electrician would have.
