Because everything has a story lately. We had a 2nd failure at Sebring that I didn't discuss until I figured out what exactly happened. The last session of the day I developed a coolant leak. Quick diagnosis couldn't identify exactly where it was coming from. I drove the car to the track and had 160 miles to get back home. I filled up the radiator twice during the drive home to make it. Parked the car and decided to worry about it later like any good car guy.
A couple of months ago I had installed a new Koyo Aluminum Radiator. I have used these in the past with great success and was looking forward to a one and done solution for a failed OEM unit I had in the car. Well, the Koyo Aluminum Radiators are thicker. What had happened was .... At some point during this car's life the A/C condenser got bent. The passenger side of the A/C condenser was very close to the front side of the Koyo radiator. I put about 500-600 street miles on the car like this without any issues. But Sebring Intl Raceway isn't your every day street. Over the course of 100 miles of on track use it looks like the engine / radiator movement allowed the radiator to rub into the edge of the condenser that was bent. BAM, leaking radiator.
I went ahead and put an OE equivalent Koyo radiator into the car now as I don't feel like diving into the A/C condenser issue at the moment and the A/C is working excellent. The thinner OE spec Koyo radiator has a lot more clearance with the condenser so shouldn't have anything to worry about.
Never a dull moment.
