Operating temp Cayenne S 04

[icebird757]

Hi guys. Sorry about me bringing this topic up once more but I have been trying to get to the bottom of this and all the discussion that I have read does not lead me to the place I want to go.

So what I am experiencing is that my CS is running hotter then Im comfortable with. I have been seeing the coolant temp go up to the 3/4 marker aprox 100C (215F) then as soon as the fans go on it drops down to 80C (180F) this continues to go on in stop and go traffic and even if the car is traveling slow <40 kmh (25mph)

I have tried the AC compressor trick and that does not work for me.

The oil temp is rock solid @ 85-90C (aprox200F)

Sometimes I smell traces of coolant from the AC but this happens randomly.

My climate is rather cold winter average around 0C (32F) and summer time it hits 15-17C (59-64F)

I also have the durametric ( not knowing fully how to best utilize that tool)

I have included the pictures I tookmfrom the live data

Any suggestions about how to solve this issue is appreciated and many thanks in advance guys.

Regards

I believe that the temperature should remain fairly stable. I have an '04 CTT with somewhat similar symptoms. In stop and go traffic, the needle starts to rise until the fans kick in. On my car, I think its the water pump. There is a way to see if the water pump shaft is loose. This video shows them prying the pulley and you can see the belt moving.

Great. Thanks for this info...did you already replace the waterpump to see if that fixes the problem ?

So far I have checked the water pump and there is no leak visible there and no play at all...so Im back against the wall now....

ANY other suggestions about what might be causing this ???

I found a bit of coolant dripping from the water pump so I finally replaced it but I still have steam coming from the front of the engine or radiator, so no, it didn't completely fix my problem, although I don't think the needle went as high as it did before.
