GM cars in the early 1990s use electric fans that mount in front of the radiator behind the grill.I had one on my 1950 Chevy 1/2 ton and it worked great.I hooked up mine with a toggle switch,but you can go to the auto parts store and get a switch that will turn it on automatically.You should use 10 gauge wire,as the fan pulls alot of amps.If you are interested i will get the names and years of the cars that use the above fan.
