coolant replacement

[aaronliu]

Is it true that Cayenne S antifreeze coolant never need to change? I saw it somewhere on Porsche's website. The service manual says check coolant level, but nothing about change coolant.

I live in southern part of Taiwan, the temperature here is 25~35 celsius, (around 70~90 fahrenheit) all around th year.

Most of vehicle here change coolant, break fluid and AT fluid every 2 years or so, due to the warm weather and bad driving condition here.

So should I go ahead and change the coolant every 2 years like most of the vehicle here, or should I follow with Porsche's manual?

P.S. My cayenne is a self-imported car from US, so it is not service at the local Porsche dealership (They charge extreme high for all Porsche not purchsed from them)

Also, I would like to know how often should I change the AT fluid, too. I have tiptronic.

Thanks

Yes, Porsche says it is lifetime coolant - as long as it is not contaminated.

Hi,

my Cayenne S 2008 has the "check coolant level" light on. Given the thread above I am not sure what to do next (I have checked the coolant as per manual looks fine but the light is still on). Should I take it to the dealer now or try something else? How dangerous is it to drive in this condition?

Many thanks

When the coolant level in the expansion tank is OK, check the sensor in the tank and/or the wiring.

I just had the check coolant light come on yesterday in a freezing rain storm. Let the engine cool down and checked it when it was still a little warm and the level is just below the "min" mark on the gauge. That being said, started the engine back up and no warning anymore. Will be going to get some coolant to top it up with in the meantime, but does anybody know if the coolant hose problems in the 04's is also a problem in the 08's? Not sure where to go with this. Maybe just top it up and see if it happens again?

Thanks all.

Fill the expansion tank till the "MAX" mark when cold and keep an eye on it during some days. Concerning your question regarding the cooling pipes of Cayenne MY06 and older, which were made of vulnerable plastic, and replaced by light alloy pipes as upgrade, MY08 (DFI) are again equipped with plastic cooling pipes admittedly a new design cause the different fuel lines of a DFI engine. It looks like the history will repeat after 100k Km. I hope not.
