Greetings friends,

1982 Porsche 928s. My water/antifreeze level in the radiator coolant reservoir is nearly zero. I found this out when I noticed steam coming from under the hood. The steam was issuing from the left corner of the block radiator accompanied by a hissing sound which I am assuming signals a leak in the radiator. I want to refill the reservoir with coolant to see if that is definitely the case. A friend of mine told me there should be a bleed screw about a hand's length from the top of the block and in between the block and radiator. I searched for one but could not find anything that matched his description. Could someone please share a photo of theirs? I was told to fill the reservoir until coolant trickles from the bleed screw (bolt), tighten it, and then resume filling the reservoir. Any other suggestions? Thanks in advance!! Regards,

There is no bleed screw. Your friend is thinking about the 924/44/68

Fill the reservoir to the half way point and then test.

You can squeeze the radiator hoses to help burp the system, but it is designed to self-burp, but it may take a few times of filling, running, filling, running.

It sounds like the gasket between the radiator and the tank has gone. That's a common failure. There were kits out there to replace the gasket but evidently it's a tedious job and easy to mess up. So, you might be looking for a good used radiator.

You should have a coolant low light on the instrument pod. That should have illuminated before you got to empty in the reservoir.

after you refill, run the engine til pressure builds and see where it is leaking.

He could also go tp Autozone and borrow a coolant pressure tester an find the leak that way also.

Any idea where these kits can be purchased? Thanks to everyone for your time!!

Give Jeannie a call at (828) 290-9280 - the tank seal is still shown on our website @$10. You may have to leave a number for a call-back.

Make certain that the leak is not a failing plastic tank before you order. She should be able to get the tank and/or the seal.
