5 /5 Joe B: I was racing at Sonoma raceway , and my radiator sprang a leak after one of the sessions. I found Mervs radiator service nearby, and drove there to see if it could be fixed. Clint got right to work on it, and found the area it was leaking. He recommended replacement, but would try to do a temp fix to get by for the week. Clint did an excellent job and the fix held up through a 45 minute race with no issues. Great work and customer service.
