Why is the Radiator Fans coming on after my car has overheated?
I have a 1992 royal 88 olds and when I start the car the radiator fans come on full speed and then go off after 30 seconds and then the radiator fans come back on after the temperature passes 200 degrees but low speed, Ive replaced the coolant temp sensor
there are 2 fuses & relays in that system. one for high speed and the other for the low speed. be sure to first check these parts quickly, figuring that the new cts you replaced is good, and if the relays test fine, it can be either a wiring






Martin Truex Jr. – who tested along with Earnhardt Jr., Nemechek, Aric Almirola, Joey Logano, David Ragan and Marcos Ambrose – said he believes NASCAR will have to look at the cooling system and a new radiator to keep the drivers from doing the two-car
Available only on manual GT Mustangs with a 3.73 axle, the package gives track enthusiasts an engine cooler, upgraded radiator, performance friction brake pads and the same TorsenВ® differential that's on Mustang Boss 302.
