I just got my 05 turbo back from the dealer who replaced :
belt tensioner(i only have 36,000 miles)
belt
turbo intake(belt shredded it up)

I stepped on it a bit today and got the check coolant message on the display.

Is there a certain type Porsche specifies?

 

ok so i checked the manual and its the orange "dexcool" type, it took 3/4 of gallon, Guess the tech missed the part that when the belt goes the truck overheats and will need some coolant

 

You shouldn't run out of coolant in normal conditions. I suggest you check for leaks.

 

you must have missed the part about my belt tensioner seizing and the belt shredding causing an over heat condition
