A conservative mechanic did it for me... he doesn't believe in engine
conversion or modifications... this is about as far as he goes... I live in
Southern California... at one point does the fan usually come on??? Its ran
cooler ever since its been in... except when a hose to the radiator was
loose.. and after I tightened it returned to never above the midpoint... we
get a lot of stop and go traffic around here... too much... If I had a
bigger stock like oil cooler then the water would warm up quicker wouldn't
it... I don't think it was after market... but another German manufacture...
