Engine Temps after shutoff

[zak996]

Hi guys,

 

I got my first Porsche earlier this summer - love it. A '99 C2. I've spent time here lurking and reading up on it to familiarize myself with the car. I'm pretty handy and looking forward to doing as much maintenance myself as I'm capable of. 

 

My question is - When I shut the car off, the engine bay stays hot for a long time.. like over an hour I've noticed its very hot the the touch by the spoiler. My temps while driving seem normal from other posts I've read. Just to the right of the 80 in stop and go rush hour. So do the rad fans or the spoiler fan kick on even when the car is off, or once you shut the car off no fans. 

 

I've used the search function and read both - no fans after shut off and yes theres a timer sequence for high temps. I guess I'm not familiar enough with the different models to determine what mine should be doing. 

 

Any advice appreciated, Thanks,

Edit - I mean the needle is just right of "80" not 180.. Just past the 12 o'clock.

When engine is off, the power to the radator fans are cut. However, the DME still keeps monitoring the engine compartment temp for some time and if that gets too high or stays high, it will turn on the spoiler fan.

If the spoiler fan is not working, the low coolant warning light should blink. If you have Durametric, you can activate the spoiler fan.

The engine will stay warm for quite sometime especially if you pull the car inside the garage.

Hey thanks for the reply.

 

No lights are on, I know the fan works as I've heard it on, just not after the engine is off. Any idea what temp would be high enough to set it off? I've shut engine off between 80-100c and nothing.

 

Thanks,

Zak

My rear deck fan will start up, not immediately but, up to about 15-20 mins after shutting the engine down and may run for 5 -10 mins. I'm in very high ambient temperatures though.
