I bought a used 2004 cayenne s and the manual was missing from the vehicle.

Where is the radiator cap located ?

Can i use regular anti freeze ?

The "check engine coolant " light lit up tonight .

Thanks

 

For the Cayenne: There isn't a radiator cap on the radiator, but instead you add through the coolant expansion bottle. It is under a small access panel in the engine compartment.

Coolant doesn't just disappear for no reason, so you will want to track down where the coolant is going.

 

Ok, i need some caffeine this morning as I thought this was a Cayenne post, or else it is a cayenne post in the cayman forum, lol.

IIRC the cayman uses the same fill setup as the boxster and the coolant fill is right next to the oil fill in the rear hatch compartment (small flip down access panel).
