Of that much I'm sure you are correct, Bill, but what about: "Steering felt normal in paddock so I went back out. Same result. Checked PSF and it was
full." I.e., it did it w/ a full reservoir.
Some background. At St.Louis last year I cranked up to go out and heard the characteristic PS howl. Checked the fluid and it was empty or close to it. But in the previous session I never lost power assist. I filled it up and started it up and realized fluid was leaking onto the header. Not good! I feared the Cayman curse but it turned out that I had a pinhole leak in the return line. Car was 3+ days at the St.Louis dealer and cost me $2000+. They said the pump was OK.
Bottom line is that I was not totally devoid of fluid and never heard it howl but still lost power assist.
When I got the car I bought an underdrive pulley but could not get it on because of the lack of clearance w/ the 3.8.
I already have a center radiator so where would a real cooler go?
