Does anyone know if Porsche offers an engine block heater, in case your Cayenne is parked outside in very cold weather?
My wife's Excursion with PowerStroke diesel has one and I have been able to add them to some of my other cars.

 

probably not, but if you feel it's necessary, i would think that you can do something aftermarket. check into an aircraft engine heater.

 

Thanks. Hadn't thought of that one.

Years ago I had a Nissan Pathfinder and they offered an engine heater that went in between the radiator return hose to the block/water pump.
Just cut the hose, insert, and you're done. Worked very well.

 

i am sure that you can modify an aircraft engine heater, if you want to.

 

Option 7VE pre-heater with timer
