Here is a crazy question but I'm going to ask anyway.
I have a 1992 Chevy K 1500 5.7L Engine, it has the old style raidator clutch and fan.
My friend has a 1999 Chevy K1500 5.7L engine, and it has radiator cluch and fan too but its a differne design, both the clutch and fan are different.
My question is this: Is the new style radiator fan better at pulling air across the the radiator. I noticed that the OEM GM fan is similar to the style used on the japanese products.. (large mult-blade plastic type fan) which appears to me to work very well. My toyota pickup had a simialar setup and I don't think you could make it run hot no matter what you did..
I realize that the pulley system between a 92 and 99 truck are different, I've not checked the trucks to see if the fans turn in the same direction or even if it would be possible to install the 99 clutch and fan along with the water pump pully on a 92 model truck, or for that matter would it make sense.
ITs getting hot here in AL and I noticed today when I had a long wait and extended idle with teh A/C on the truck was approaching 210F. While I realize thats not excessive I wonder if there are other solutions that might cool better. The truck has a large radiator , core is approx 19*34 (be-cool) radiator and it also has a full shroud.
Once the truck is moving it runs around 180 to 190 with the a/c on. I have a 180F thermostat.
Any comments?
