Hi All,

Went to drive a friend to the train station this morning around 530am.

For the first time I believe, I used my defroster. It's so muggy where I live that the only way to have a clear windshield this morning was to turn the defroster on. I was going back and forth between that and the AC since it made the car unbearably hot.

30 minutes later, I got the warning to pull over and saw my engine temp was 250 degrees.

I immediately turned off the defroster, and turned the a/c off. The engine temp immediately went down to the middle (normal).

As I was 5 minutes from home - I left them both off - and the temp remained in the normal position.

Car has approximately 9000 miles.

Should I add Engine Coolant in a few hours when I go to work at 830? (should be cool to open the cap).

Has this happened to anyone else?

Is this something I should just not take a chance with and call Ray Catena?

Thanks for your advice.

Brad

 

Change/cross Over Valve (COV) issue. Well know and documented.

 

Thank you!

Would it be safe to drive to Ray Catena in New Jersey from Brooklyn with my A/C off or is this gonna be a tow job?

 

Morning Bradley, that's a tough call. One I'm not willing to make/risk on your car. It's not a "low coolant issue". Call Catena when they open, and take their advice, and let them "own it".

 

Will do. Thank you!

As it goes - I went on their site and checked out their service schedule. They're apparently booked till October 9th and then booked on the 10th - opening again on the 11th.

I know in emergency - they can take any car - but they might not have a loaner available - which I would definitely need.

 

I had that issue in my .1 and once the temp regulated it was fine to drive. Of course I kept my eye on the temp but I was good to go until I made it to the shop. I also had a COV fail that prevented the PSE from engaging.

Also, when car overheats you can turn on heat to remove heat from the engine if stopping if not possible. I was actually stuck on the Belt Parkway going to see my girlfriend when the car overheated.

Good luck. Keep us posted.

 

Bradley,
It's the "Superman" issue! Sapphire Blue over Red/Black causes this

I had the same issue, take a look at this thread https://rennlist.com/forums/991/9328...991-2-a-3.html

Good luck!

 

I’d call the dealer and have them squeeze you in (ask nicely)

Bradley’s car is a .2 which I’ve read nothing about any COV (change over valve) issues. Was a small problem in early .1’s (2012.2, 2013, maybe 2014 at latest?)

 

Rennlist is great. An online 991 DOCTOR

 

Yeah, can’t believe this issue is still popping up.

 

I believe there is also a Porsche dealer in Manhattan? At least there you have alternate transportation. Overheating can damage a car if left for long periods.

 

Update: Drove from the house to the office - about 30 minutes from door to door - on the belt parkway in traffic - stop and go - with a/c blasting 100%. The engine temp remained normal the entire time.

Will try again later with the defroster on.

Thanks one and all! A real family here.

 

What exactly is the normal running temperature?

 

For coolant, Porsche has pretty much made the gauge stop reading at about 194.

For oil, you'll see numbers as low as 190-ish, and get to about 232 with normal highway cruising.

 

190 to 195 I have noticed. This one occurrence shot it up to the max line of 250.
