Pusher Fan

[NMBronco77]

I have a 77 Ranger with AT/PS/PB. I installed a HD 4 core radiator. I also have a AT cooler and a PS cooler on the front of the radiator. This unit came with Air conditioning and I intend to put it back in. Because it had A/C it has a 3 row crank shaft pully. This means I have to have my fan moved 1" to 1 1/2" closer to the radiator in order for the fan to clear the pully. This puts my fan less than 1/2" from the radiator. I bought a radiator guard but it just seems like the radiator is too close to the fan for comfort. I am thinking about removing the stock fan and fan shroud, and moving my PS and AT coolers to the back side of the radiator, then installing a pusher fan in front of the radiator. Anybody tried this. Am I asking for trouble here? I know that I can gain a little more HP to the tires by getting rid of the belt driven fan, But I DO NOT want to have my rig heating up on me like it used to. What a pain in the ass that was.

So, can someone share their experience with me in this area? I have been working on this rig for over three years now and I would really like to solve these last few problems.

Are you using the factory fan or a flex fan??

Have you tried different length fan spacers?

I went this route after the fan went thru my radiator.

You do gain some extra power and will not sling mud and water in the engine compartment but it doesn't keep the temp down enough on hot days and high RPM driving. I added one in front as a pusher and one in the rear as a puller.

Seemed to run at 180* most of the time until I go up hill or get on the freeway.

These fans only run at one speed so the fan can't keep up high RPM's where a mechanical fan spins as fast as the motor to keep cool.

The nice thing is you can turn the fan off, sit to cool, restart and recycle the cool water to get going quicker.

An added oil cooler would help with the electric fan.

The fan I bought was a Spal brand from WH, and they say that it is the highest cfm fan available so I am in hopes that it might do the job for me.

After talking to a guy named Mark at WH, he helped me understand how to mount the thing. He said that if you are setting in the driver's seat and looking at the radiator, mount the thing at about "8:00". I did this and it fit real well. I was concerned that it was not mounted right in the middle of the radiator, but he said that they have had real good experience with doing it this way, and with 2700 cfm going through that radiator, I hope it will stay cool. Did I step on my **** by going this route? /emoticons/[email protected] 2x" width="20" height="20" />

I don't have an oil cooler, and I am not sure that I have room for one because of the tranny cooler and PS cooler that I already have mounted in front of the radiator.

I guess I could just start stacking them up.

No need to stack the coolers up, mount it in the engine compartment somewhere, it will help no matter what.

Sounds interesting about the 8:00 area of the radiator and makes sence due to the water flow out of the engine. why didn't I think of that? Give it a try! I might go back to that route if it work for ya.
