- Jul 25, 2004Do you run a fan shroud?Corey----- Original Message -----From: mpascino_nySent: Sunday, July 25, 2004 7:51 PMSubject: [Cadillac_Performance_Association] Re: 1980-1985 eldo/seville cooling....need help, how to succesfully pull it off???Just an update.... I am still have trouble keeping cool........I have
a new radiator, new fan, new clutch, new waterpump, new thermostat.
The head gaskets are new(rebuilt motor) and the cooling system passes
a leak down test. I still don't think there is enough air flowing
through the radiator. I am stuck. The car even runs warm at 65 mph,
there is plenty of air hitting the radiator at that speed. Does
anyone have any ideas!?!???? It hasn't over heated yet, but I am
more than confident if I took it on a trip I would have trouble.
Cody, did you have any problems keeping the 472 cool?
