Default Bleeding coolant

Hi guys, what is the correct procedure for filling and bleeding the coolant system on a 944? Do I need to raise the car or anything? Cheers

You don't need to raise it, but it does help if the car is parked slightly uphill. Start the engine with the coolant tank cap removed. Fill coolant until it stops taking it. Let the car warm up. Once the car starts to get near operating temp, crack the bleeder nipple on the coolant neck (early 83's still have the coolant bleeder on the upper radiator hose if it has not been updated), air should come out. Close the bleeder. Let the car run for awhile, and repeat. Sometimes the early cars can be a real pain to bleed. Often if the bleed screw doesn't get all the air out, I will let the car sit and cool down overnight, which usually will burb a bunch of air out, and you can just add coolant in the morning, and give it a quick bleed and you are done.

Comes right off the top of the head where the upper radiator hose attaches.
