electric fan

[chevy 37]

I can't fit a mechanical fan in my truck since the engine is to close to the radiator. I will have to go to an electric fan andwas wondering if it's better to push or pull the air

I have the fan pushing the air through on my 37 chevy p/u and I have not had any problems yet,what motor do you have?. I am running a 57 235 and with a shortened pump the pulley is too close to the radiator and too far down. When I get the new chassis done I think I am going to look into the adapter to mount a 216 and early 235 pump to the 55-62 235s if I keep the 6. Jeff

The engine is a 305 bored to 315. I had the stock radiator redone when I first built the car, but it started leaking so I bought a new Griffin and mounted that. I had always had a problem with heating when the truck was sitting in traffic as the way the motor is mounted I could only use a 12" fan which covered only the very bottom of the radiator. With the new radiator I cannot mount a mechanical fan as it touches the radiator so I bought a set of flex-a-lite electric fans and mounted infront of the radiator. As long as I am moving the temperature never goes over 180, but sitting in traffic it heats up quick. I have set up the fans to come on at 200 and they do bring the temperature down quickly but I have it set up for push not pull. I'm running this in a 37 chevy pickup. I have a high flow water pump. I just don"t like it heating up in traffic. Any suggestions. Bart

Bart, when you are moving, the fans obviously do not come on, which is good. However for sitting still mode, you have the fans set at too high of a temperature. Set the temperature at 180 for the fans to come on.

Typhoon ZR Thanks for reply. I had previously set the fans for 180, then 160 and both worked,but sitting without moving for 5 minutes I find the fans recycling every few minutes. There doing what they are suspose to. It's just that I don't like the electric fans and since I can't use a mechanical fan I guess I'll have to pull the motor and relocate it farther back against the firewall to give me more room to use a mechanical fan..Bart

Street Anyone who can describe 5 & 20 coming into Auburn as nothing but red lights is right on. I've played that game to but I love to rev my engine up and let the mufflers talk and then the grinning kid next to me in a jap import takes off trying to lay rubber and I'm calmly turning right. Your right about the electric fans, but to me they are annoying thats all. Bart
