For those of you chasing leaking problems, I just set this up for mine and found the problem in record time. I made it out of air-tool bits I had rattling around in a drawer.

Just disconneted the hose at the top right of the rad, capped off the rad, and put a valve on the end of the hose. PRessured up to ~14psi and found that my short hose (between the block and the heater valve) was cracked on the bottom where I couldn't see it. FASTEST troubleshooting in history! Just gassed it up and closed the valve to keep the system pressurized when I hunted for the leak.

Ahhh the $1000 radiator! How did you fit the black aluminium panel, that sits between the rad and the condenser?

I removed it from the original and drilled a few of small holes, then threaded some 5mm allens in as set screws. You can see one of the sticking out in the picture. It almost stays on by itself with a bit of crimping, but I figured the set screws would ensure it wouldn't move.

I think the rad was only $899, too.

Great idea fraggle! Thanks for sharing it.

It was well over $1000 to get one up here. Thanks for the info. I will do what you did and install a couple set screws.

Come to think about it, they arer much smaller than 5mm. O pulled them out of my Radio control spares box. Either way, the method works!

If that's the 928MS radiator, I have one too and it's nowhere near $1000, more like $700 and it's beautiful. Thanks for posting this because I'm now chasing a leak too, great idea.

Excellent idea for troubleshooting coolant leaks! Simple and effective - I LIKE IT - THANKS for Sharing!!

Hey, my 928th post - I was wondering what I would be posting when reaching this milestone - time to celebrate - THANKS, Fraggle!

The one that thas both coolers, then add the shipping, brokerage fee at the border, duty, taxes and so on, and the total was over $1000CDN. I can scan the bill in if anyone wants to see it.

Forgot about the coolers, that gets the price to $855 plus extra stuff. Still much cheaper than OEM and it's a work of art. My brother, who's in the auto parts biz, took one look under the hood and said "Damn that's a beautiful piece of work. Too bad it's under the hood."

As soon as I get home I'm going to run the same test on mine, really simple idea that works.

Interesting, OEM is cheaper than that here - I was quoted $AU850 locally ($US750 at current (high) exchange rate) for a Behr 928 radiator - for '89 5-speed rad (integrated oil cooler, no trans cooler).

I looked up the Behr part numbers on their website catalogue and called my nearest wholesaler - didn't mention the word Porsche at all, to avoid the "tax"
