Took the car to drop off some dry cleaning and noticed the green stuff puddled and dripping under the radiator. [img]style_emoticons/<#EMO_DIR#>/ohmy.gif[/img]
Popped the hood and inspected, what I could, in the parking lot. Couldn't find where it was coming from. Took it home (temp remained fine) and got it in the garage. Removed the airbox and got some light in there. <b>Low and behold. Its that little rubber cap/plug at the top of the radiator.</b> It now has a little pin hole and is spraying the oil filter with coolant.

I got on the web, went to Paragon and pulled up there parts catalog but Its not there. Unless I missed it. the picture doesnt even show the spout.

I'm viewing page 34 and the plug should be at the very top of the radiator above the lower water hose (passenger side).

Does anyone know how I can find a part number?

Perhaps a pic would help.



Note the right upper spout. No hose travels to this point, It simply has a rubber cap on it. Below it is the lower hose leading to the engine.

I just need to replace that cap.
Tried advanced auto and they don't carry the right size. I ended up buying a multi pack and none of them fit. I'll call paragon and sunset tomorrow.

OK I got it. Well I got the number from sunset. Paragon and Automotion were both stumped. Phil at Sunset also didn't see what I was describing at first. He put me on hold then came back with a "I FOUND IT!". He cross referenced it with a 944 S2 and there it was.

And here it is, should anyone else ever need it:

Our radiators also use 1, Block off Cap <!--sizeo:4--><!--/sizeo--><b>part # 944 106 103 02</b><!--sizec--><!--/sizec-->

This is slightly larger then the typical 3/4" bypass caps that are in every auto store making them a PITA to locate and replace.

Glad you found it -- I also replaced the exact same piece earlier this year. Found mine at Pelican.

I've experienced a broken radiator plug just like many other owners. My radiator cap has not been sealing for a month or so and I've been topping up with water - yes shock horror - tap water. I only realised the error of my ways when I logged onto the forum to check how I was going to flush the system. I read about the drain plug being prone to snapping so took extra care when trying to realise it, all to no avail. Coolant started leaking slowly so I had to find a way to get the plug out. I have read that others found this not to be an issue. I did.... lying on your back in a pool of coolant makes it tricky and as the plug was broken well into the radiator I really wondered how it was going to be possible. I had no reverse drill or easy out, so I improvised by scoring a line with a scalpel blade until I could get some purchase with a flat blade screwdriver. As I was doing this on a Sunday there was no way I was going to find a new plug so I rummaged through a collection of bolts to find a thread match with the plug. I then used some plumbers tape to seal the new plug and gave it a test. The bolt is certainly not torqued up but has survived a good few test runs at high running temps. I used Prestone concentrate with distilled water for the coolant.

My porsche mechanic has assured me that if its not leaking then the bolt will not pose an issue until the nylon plug arrives and that its only nylon due to cost. Strange to skimp on this part when most others are very well engineered.

I replaced it with an iron bolt. Its American threath. Funny, because the rest of the car is metric.

Works great and it cost less than the P(orsche)P(lastic)P(art).
