Post subject:  Audi/CSM radiator install pics

Well after having cooling issues with my Civic radiator in the NC heat I decided I just needed a bigger core that would hold more coolant. After looking through Paul's pics from the shootout I noticed that PTColt's radiator setup was under his radiator support instead of behind it like the factory radiator was. He did it to make room for a larger turbo and manifold but I wanted to use the same setup because I had already built all my intercooler pipes around the smaller civic core and I didn't want to have to go back and redo all that hard work. Paul told me that he had used a radiator from an Audi so a quick PM to PTColt confirmed that I needed a core from a 90 or so Audi 100. One hour at the junkyard and $20 later I had what I needed.

Now I had to make this thing fit the Colt. I took some measurements and broke out the grinder with a cutoff disc to make some room. I soon realized that in order to make enough clearance for the radiator that I would weaken the bottom support that I had to trim. After trimming off what I needed to I decided to test my welding skills and box in that lower support, that way it would still be as strong if not stronger than it was and I would have plenty of room for my new radiator. My before pics didn't come out so well but the after pics looked pretty good.

Now that I had clearance I needed a way to hold it in the car. I decided to use the holes that held the stock Audi fan on. I fabbed up some mounts out of plain flat bar, I used the same mounts to mount an aftermarket 12" fan. I just drilled the holes where I needed them and then welded a nut to the back of the flat bar so that I could just thread my bolts in and tighten them up. Here are some pics of the upper and lower mounts.

I also had to swap over to the DSM water neck since the Audi radiator doesn't have a cap.

Some minor trimming of the upper core support and the back of the drivers side metal headlight housing was also required to make room. I also took out the wiring harness and ran it in front of the core support and then snapped it back into it's original spot. This is easier said than done because you have to unbolt the passenger side fuse box and everything hooked to it and fish it through to the drivers side. Then run it in front of the core support and hook it all back up. The ends of the harness interfere with the radiator if you don't and it won't sit up under the core support. Sorry, no pics here.

It's also a good idea to take your radiator to a local radiator repair shop and have them take it apart and clean it and replace the end tank gaskets. I wasn't about to trust a 20 year old radiator to my freshly rebuilt engine. This costed me an additional $60

Hope this helps someone, also thanks to pma1123 for the pics and PTColt for letting me know which radiator to hunt down. I will also get the part #'s for the hoses that I used.

I wanted to but there isn't room between my IC and the radiator. I mounted one behind the radiator in the stock location as a puller. There is plenty of room beside it for another one but I'm sure the turbo/manifold will melt it as it's plastic.

Because the Audi radiator tucks up under the radiator support, it's only about 12.5" tall. Plus I had already built my IC pipes around the civic radiator and didn't want to have to redo all that. The way my pipes were a regular sized radiator just wouldn't fit. I also needed something no wider than 26" and most radiators are about 27" or so wide.

Now if I ever decide to throw a big turbo and manifold on this thing I'll have plenty of room to work with.

What were the hoses you used 89Mirageman? I'll close up the thread and move it to the archives once we get those final details. 8)

I've looked and looked for the stickers that came off of the hoses and the receipts where I purchased them and I'm having a hard time finding either. If you want you can go ahead and move it and I'll keep looking. Thanks
