Why does my Porsche 944 radiator overheat?
Another scenario where the pressure cap may release is if it gets very cold and your anti-freeze is not up to snuff. Your radiator, being in the slipstream of the cold air, may freeze up. Then the coolant will overheat and the pressure cap may release. If this happens, you need to resolve the problem.
What kind of coolant does a Porsche 944 use?
Modern radiators, including the 944’s, are made out of aluminum. Historically, radiators might have used copper or brass. The tubes are supported at each end by header tanks. These serve to collect the incoming and outgoing coolant. BTW, for this article, coolant is understood to be a mixture of water and anti-freeze.
Why does my Porsche 944 run at its highest speed when parked?
When restoring my 944R, I found that both fans run at their highest speed when the fan switch reaches it temperature setpoint. A lesser known fact is that one fan will run at a much lower speed when you park a hot car and turn off the ignition. This serves to continue cooldown of the parked car.
When did the Porsche 944 front engine come out?
The Stuttgart company released a series of front-engine, water-cooled cars, first with the 924 in 1976, then with the 928 in 1978. The Porsche 944 appeared in 1982 as a more performance-oriented take on what the 924 initiated.
