I brought my car into the dealer for getting a "Service Power Steering. Drive with Care." warning and the engine temp was getting pretty high on a 110 degree day here in Socal. They said no codes came up and that they drove it for 14 miles and couldnt replicate the issue of the heating. (maybe they weren't driving it in manual/paddles Like I do, or driving it how I drive).

I drove her home from dealer and it was 105 degrees outside. Its a 20 minute drive and sure enough right before I get home the Coolant temp Maxed out and oil temp almost red lined and AC was shut off (It has never done this before). I have never tracked the car, no mods, and this is just every day driving. Obviously on a track it would be useless even driving to get there! How do I prove this to my dealer that it is overheating if they can't replicate the issue?! What do I do??

I see all the threads of overheating on the track but this is just driving on the street and for only 15-20 minutes!

I got a video to send to the dealer but they closed at 7pm so Ill have to wait to hear from them in the morning.

Sorry that you are having this issue. This is not normal so don't think it's a common problem. Something is wrong with your car that needs to be fixed.
I drove through Death Valley from Spring Mountain to So Cal in ambient over 100F followed by stop and go on traffic on 15 freeway and my coolant was at 220F and oil almost the same.

Drove many times in hot weather and never came close to overheating.

It's pretty clear that the dealer f'ed something up in your engine. Has nothing to do with "track overheating" problems caused by inadequate cooling.

Hmaringer

I mean I drive it pretty hard but no where close obviously as I would on a track. I just don't know how it didn't happen when they drove it. Unless they kept it in Auto mode where it shifts to higher gears super quick. I drive with paddles in manual mode always.

Driving it hard holding lower gears in 105 ambient for 20 minutes is different form commuting. I guess you should show a video of the 20 minutes prior to overheating.

Hmaringer

So it can't handle driving in lower gears in 105 degrees is what you mean? Is this normal? I do drive the thing relatively hard but isn't that whats its suppose to do? Its nothing like I would drive on track obviously. Im going to get an SD card to record with PDR.

Anyways it getting this hot has to be HORRIBLE for the car.. Not sure what to do

JackTripper

Maybe its that Bull$**** 91 octane gas that you have in the Peoples Republic of California.

Run your PDR and get it to over heat then take it in. Something is off with the car unless you are running 4-6.5k near continuous on the street. My '16 A8 does fine here in SoCal on the street and I drive it pretty damn hard in manual. Track is a different story.

I drove my car home from the dealer when i bought it which was 2.5 hours in 95 degree weather last summer.

Temps never went above 220f.

Granted i have an M7 and was just cruising home and not driving hard, still. Something is wrong with your car.

I live in Phoenix AZ...and it's always hot here in the summer. 110-115 is normal. I drive my C7Z (M7) pretty hard at times and have never even come close to overheating on the street.

Clearly something is wrong with the car or the maintenance.

davepl

It really depends on how hard those 20 minutes were. I can conceive a situation where, with the ambient being over 105F, you could push a Z over the edge on the street.

I mean we're talking Bullit or Ronin or French Connection, but it's still likely possible, I guess...

More likely something is wrong with the car, but I wouldn't rule it out entirely just because ambient was SO high.

Actually your video doesn't show the engine over heating. It is close but not actually over heating. The coolant and oil temps weren't maxed out in your video. Turning off the AC was an action taken to reduce the chance of over heating. Did you get out of the car and see if the fan was running? If the fan isn't running you need to be over 35 mph for the engine to cool. Buzzing the engine in lower gears to hear the noise will make it run much hotter due to increased frictional losses. If you weren't at wide open throttle in the lower gears then you could have run just as fast in a higher gear using a wider throttle opening.

262 degrees is the max for coolant and I am not sure of the number for oil but you were below it. Use the digital gauges on the Tour Display as those analog gauges have too low of a resolution to see what is going on.

In mean his gas is topped off so I'm just assuming if he was driving it hard in a zo6 there's no way he would be at full levels lol just my 2 cents

william wyatt

So funny how all these overheating issues are going on but CHEBY takes no responcabilty.Like I said POS.

DebRedZR1

LEAVE the personal attacks OFF the Forum!!!!!!!!
There are issues with these cars, debate the issues, provide info or go someplace else to continue your juvenile dramas.
Not everyone is a technical genius, I sure as heck don't want the dealership driving my car 130 plus to duplicate the issue

ronsc1985

Seems to me if you're paying attention you would see the temperatures climbing long before the car software took corrective action. The temperature gauges are there for you to look at, use them. You could then provide a coherent explanation to the dealer about what is actually happening.

The only way the temperatures would climb rapidly enough so you, with minimal attention, wouldn't catch them is if you had a catastrophic failure like a stuck closed thermostat or malfunctioning water pump.

This isn't a case of overheating at the track, which a dealer would have a hard time repeating. This is a case of driving on public roads ostensibly somewhere around the speed limit.

Looking at his oil pressure on left & again when he scrolled thru the individual gauges, it is extremely low even for idling. Mine is normally just a tad (tiny) bit under 40 psi. I'll probably get blasted but that seems to indicate something else going on (mechanically) other than just "spirited driving".

Les

I noted that too and was going to make a comment- until the hostile crap started flying. That's obviously not normal or healthy oil pressure but it could simply stem from the hot temps that the car was running at the time.

NicD

Yeah, here in Phoenix it hit 120 two weeks ago and I was driving in stop and go rush hour traffic for 30 minutes and the highest my coolant temp got was 210. Then I got off the freeway and drove to my house which is another 10 minutes of side streets where I was rolling into it quite a bit in manual mode and generally just screwing around and I hit 220 at the highest, that's it. It's an auto too without a secondary radiator.

Needless to say you have a mechanical issue because that doesn't just happen on these cars.

Dude you really need to chill. I think it be much healthier to only click on positive threads rather than if someone who is having a problem no matter what it is.

Seriously, just enjoy your Z and refrain from entering threads like this, no1 is forcing you.
