Weeping radiator
 

I have VERY slow beading coming from the radiator. When I did the vacuum test, there was no pressure drop. However, when I filled with coolant I saw droplets on the floor at the radiator. I opened everything up front up and saw the weeping (both me and the radiator).

I posted a WTB on the radiator in the classified ads.

Any other advice?

I replaced my center radiator two months ago (on an S) and it's not a bad job. Most difficult thing was finding all the fasteners on the bumper cover -just when i thought I had them all, I would find one more. The ones behind the side marker lenses were the b*tch. Once that's off, the radiators are straightforward. They go for about $200 online.

One tip - get a couple of needle nose vise grips and pinch the radiator hoses so that all your coolant doesn't come pouring out. I only had about two cups come from the center radiator.

Should I buy the Behr or the Silla radiators? There seems to be a $100 difference between the two.

Anybody have experience with the Silla radiators?

A cheap and easy repair. I put a Behr in mine. If you are a smart guy you will pinch off your coolant lines so you don't dump all your fluid, and be sure to follow Pedro's instructions to purge ALL the air out of your cooling system so you don't dry run your waterpump and destroy your nice Porsche motor. :)
