Anybody using a "pusher" radiator fan? #755029 07/22/10 11:13 AM 07/22/10 11:13 AM

I would then leave the normal mechanical fan (mounted on the waterpump) "as is". It is non-clutch. With the temperatures that we are seeing here in the Northeast, I see my engine temperature "creep" up while idling for long periods. And after parking in my garage, I see the radiator spewing fluid out the overflow. Running on the "highway", the temperature appears fine. I'm looking at some that push over 1200 cfm. Anybody? or is this a waste of time and money? Thanks! Tim...

They each contributed to higher temps on the highway due to restricted air flow. It happened with the fans off and even more with them on. Some OEMs have had limited success with pusher fans but I don't know of any that use pushers on a recent model. Keep in mind that the OEMs spend millions of dollars researching cooling systems. The aftermarket guys spend a couple days with a computer and pop one out. There will be a distinct difference in fan capacity. We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind. - Stu Harmon

I just installed a new factory radiator and I have a 5 blade flex fan with a 1" spacer and no shroud. My Sunpro temp gauge indicates that it is at 230 degrees. It is a new gauge with a new sending unit. The guys at the shop who installed the motor are saying that the gauge is wrong (yea, I know). So I am going to buy a digital thermometer and test it myself. I am not sure if I should change the fan and also spend $150.00 on a shroud.

Tim... i run that setup due to space - it works - i have the pusher on a switch to put it on when i need it ( rarely ) and it brings the temps down in traffic.

Plus my cruising temps didn't increase. I turn one or 2 of these on with separate manual switches when in traffic if the temps start to creep up, and they bring the temp down nicely.

Now to try and use a stock fan PLUS a pusher ? ...wow. I would look at your TOTAL cooling system and straighten-out whatcha' got now.

I used the fan with a manual on/off instead of a thermostatic switch because I wanted to run it longer than the termostatic switch allowed, when temps would warrant I would throw it on and watch the temp drop.

I really need a shroud but cant seem to find one less then $250 so I bought this fan from a local speed shop for about $90 big ones. I have it on a toggle switch and only turn it on when stuck in traffic when it creeps up to 200 and it will bring it back down to 180. I still plan to get a shroud soon but this pusher fan does help.

Just get it going in the right direction and make sure the fan blade is on the right way. I used a relay with a fuse holder in the wiring off the battery. Then I used ign feed to turn the relay on and put it thru a toggle switch. That way it only works with the key on and when I turn the toggle switch on. I dont have a picture of the wiring but I can make one up if you need it. Ron

I was in a parade with a few friends/club members. The Charger next to me got hot and had to pull out. I clicked on my "pusher" fan, brought down the temp real fast, and kept going all the way through the course. Yep, they work!

I used a relay kit and hooked it to a manual switch and I use it when idling if I start to warm up. It has not affected my temperatures at speed when not on. I mounted it directly to the radiator. Works great. No Stock

I installed mine on a 4-core radiator but I also have the fan clutch working behind as well as a shroud. I also opted for a relayed toggle stich (small toggle in the ashtray) because after a drive, as the water temp rises, I like to combat it with some airflow for about 20 minutes and bring the temps down.
