radiator source
 

need suggestions for good and cheap radiator replacement sources for radiator for 91 100. i got a gut feeling that it is leaking around the driver side plastic end cap and don't want to risk alumaseal or jb weld (assuming i could find the leak, since it appears to be from the part of the radiator that is tucked ever so evilly under the fender). thanks in advance in this never ending saga that is audi!

Did some homework for you...

my local shop is doing a new radiator (lifetime replacement warranty) and hoses for $300 parts and labor. not sure of brand of radiator yet, but pretty sure it will have plastic endcaps. if not, all the better. this is what i get for replacing the water pump/tb about a month ago - the radiator got jealous for attention too!

That sounds like a good deal. My radiator on the 91' 100 started leaking a couple of years ago and an aftermarket version was impossible to find. The 91' 100 radiator is unique. A transmission cooler was incorporated into it for that year. I ended up paying around $350 for an OEM.
