I just got the radiator installed. This thing fits great. I would recommed these radiators. The only thing I didn't like is where the low coolant sensor is, the guy welded an AN male end there. I just capped it off. In the FL heat, my car never got over 170 idling in traffic with the a/c on!! The radiators are on Ebay, they are $379 for an M6 and $399 for an auto. You will have to modify the upper cover to fit over the tanks. I will post pics as soon as I get a chance to take them.

 

what are the up sides of replacing the stock one

 

Much better cooling. In FL the heat and humidity is terrible on our cars, especially running the a/c. I am building a 383 that will demand more cooling, plus I want to make sure this thing won't get hot. My original one was starting to get clogged. I had the car in storage for 3 years, once I took it out and flushed the system it was nasty. After driving the car I noticed that it would get a little warm (around 200) with the a/c on. I took a digital thermometer to the radiator and saw that I had some cool spots. I figured that I was going to be doing an engine swap I might as well upgrade now. I would recommend these radiators to someone that is looking for a cost effective radiator.

 

Why is it more expensive for an automatic?

 

Tranny cooler

 

Ooo, ok. That makes since
