Hi,

I am just wondering what opertating temps people have on their Cayennes? (oil and coolant wise) Please specify Cayenne, S, and TT.

TIA,
James

Hi James. My Turbo's oil ALWAYS runs at 200dF (after being warmed up, of course, and it does that in maybe 15 minutes of normal driving). The oil-cooler thermostat seems to work very well, too, as the oil never goes below that after warmup. Coolant temp runs at the thermostat of 180dF unless it occasionally goes over if driven full throttle often (for instance, while autocrossing).

Ambient temps in Phx in the seven months of nonsummer range from c. 30dF to 70dF.

Same here, oil@200degF, water at 180degF, with outside temperatures ranging from -20degF to 98degF since owning the Cayenne.

Same here for my Turbo.

Steady state oil temp just under 200 F and coolant temp just under 180 F.

Exact same here - great question

My oil temp sits at a steady 200F but my water temp generally fluctuates from 190F to 210F in city driving. On the highway it's 180F or a tick below. I asked the dealer about this when I had the car in for a DME remap and he said that these temps are in spec. What type of driving are you guys gennerally doing to get a consistent 180F water temp?

My oil temp also sits at a constant 200F and my coolant also "fluctuates" in congested "stop and go" driving between 190F and 210F. It does this both in hot weather (95F) and in the cold weather (5F) but only in "stop and go" situations especially, when not moving for several minutes.
I believe that it is either a coolant fan going on to cool the radiator or a thermostat opening. Cayenne also warms up very fast compared to other vehicles, so maybe it is a thermostat. But after 6000 miles in all weather, this is consistent and poses no problem. In fact it is barely noticeable. I am told (and in this case, believe) that this is normal and even desirable.
On highway it is 180F with no fluctuation at all.

Even though the car hasn't lost a drop of coolant, I smell something that smells like coolant and it makes nervous. The dealer tells me this is normal but I need the opion of the group.

Oil temp always steady just under 200. Water temp also rock steady at 180. Both without much regard to driving conditions. Curious how this will change when we get to hot 'n humid conditions in Washington, DC.

I just got an 05 CTT today and notice on highway the coolant temp is 180 but I'm stop and go traffic it goes to about 190-200 then back down to 180? Is this normal?

TozoM8

oil at 200, coolant at 180 or a hair under, but if i push it a bit it goes up 190-200. I've heard it's normal, but I hate it. It should not go over 180.

Yes it freaked me out today when I was driving. Made me super paranoid

blazing928

Water temp can go way up, that's why it's a pressurised system to raise billing point.
In racing a higher temp is more efficient , the whole heat / energy stuff.
Some brands keep the gauge at the same regardless so you think all is well, Porsche tell it like it is.
Unless the red light comes on its all ok, especially if you are climbing steep hills in low gears in high summer.
The new cars heat up very quickly for lower emissions. Even the 928 had some fancy cooling set up years ago, to reduce the thermal shock as the thermostat opens.
So watch it but unless it's pegged in the red don't worry.

It used to be interesting watching track oil temps climb after just one fast lap, it happens very quickly.

I understand your point but the thing that is puzzling me is that others dont have the same issue and some do.. Even with living in the same climate and have similiar driving habits

I have a 2004 Cayenne S, and also smelled coolant. Since changing my coolant pipes, the smell is not there. There was never any evidence of a leak - until I removed the intake manifold, and coolant was slowly leaking from the plastic pipes (the set of 3 coming from the thermostat housing).
