My electric fan

[Gubni]

Thanks to a good friend who I now owe I have a much better electric fan setup. My old one did the job most of the time, but sometimes it needed help. I had an auxilary fan that helped, but it recently died. I also installed a cowl onto my hood. That helped, but still it would overheat on occasion. I think I finally have my heat problem taken care of. This fan is off a Volvo and there's a big recall due to an electronic module catching fire. I cut off the module and rewired it. You can feel the air in front of the radiator and when I let go of some paper it clung to the grill. Since it's a single speed fan I wired it through an electric thermostat. I have a switch that powers the thermostat which powers the soleniod and I have another switch to bypass the thermostat. Of course I can turn both switches off for deep mud or water crossings.

Man that thing is pulling some serious air. I believe I might just know where you got that from... ;)

Looks like it was made for it.

I hope to make it variable speed at some point, but it works for now.

I still say a dimmer switch would work...;)

Dimmer switches are rated 15 to 20 amp and I need 30 amp. Also I would like it to be automatic.

This is the only one I've found so far. http://www.dccontrol.com/

OEM fans are the only way to go if you run electric. I always just skip the thermostat and let it run full speed anytimne the key is on. Never had any issue doing that. The thermostat in the upper hose will take care of regulating temperature. I never saw a need for the electric to be thermostat controlled also. I wire them thru a relay to run on direct battery power. That way you get the full 14 volts or so the battery actually sees/ Many times if you scab power from the fuse panel you loose a volt of two and only get 12. something instead of the full 14.

I did run it from the battery with a relay. My concern is that it may keep the engine too cool and then with the EFI it would always run rich.

I removed my 16" Zirgo while at the Outer Banks, and re-installed the 7-blade fan that came on the truck. With the electric fan, the temperature would run up to 210 degrees on low-speed drives through deep sand. With the factory set-up the temperature never exceeded 190 degrees. I either need to find a better electric fan, or find another way to deal with the water blowing all over the engine when crossing deep water.

I kept the fan wiring in place, so if I can find the right fan all that I will need to do is mount it and plug it in.

Your normal thermostat will keep the engine at proper temperature. A thermo on the fan would do noting really but maybe allow the engine to warm up faster in cold weather. Once it's up to temp, you can run that fan full time and the temp will basically never drop below the water thermo setting. I run a stock 7 blade mechanical fan on my Jeep with no clutch, so it turns 100% engine speed at all times. I run a 160 thermostat in the summer and it's still up to temp within 2 miles of driving in the morning and lays dead on 160 pretty much no matter what. It did get up to about 180 climbing the mountain in Harlan. Point is it moves a serious amout of air all the time and still never drops below 160. I run a 180 in the winter for better heat. Same thing, never drops below the thermostat rating.

Good point about that stat.

The truck use to get hot going down the road and I knew the radiator was in good shape,so I put in one of these.

After a little trail and error it fixed by overheating problem.The blazer has the same motor as the truck did.I am running a 4 core diesel rad with a two speed taurus fan.The low speed is powered when the ignition is on and the hi-speed is on a toggle switch.I drove it to Georges sat and it ran 170 the whole trip,except when I was going up the hill by meadowveiw and then it only went to 185.

I found something that might be what you are looking for Shawn.
