1988-98 Chevy OBS LS Swapped Twin Cooling Fan and Radiator Install
Channel: Laurenceville Garage
Date: 2022-04-24

Part 25:  Today the 91 OBS gets the radiator, twin cooling fans and CAI installed. The radiator is a more common 28" core 91 OBS 5.7 radiator, so install is not fancy. It is a bit different because of the fans. The fans were found on Ebay and fit a late 90's Camaro along with the wiring harness. I had to get a  bit creative to make them fit, but it was "very do-able", so you can do this at home with minimal fuss. The CAI uses parts from the donor Suburban, aftermarket parts. Not a big $ investment. More time is spent on showing how I installed the fans AND how to wire them up.
