I've mounted up the aux. oil cooler on my Hawkeye, and was thinking about mounting up a cooling fan from a water cooled atv to pull air thru the cooler, and past the engine.

I'm not sure of the output of the electrical system, and if it will even run a fan.

 

you need to find out of many out put watts the hawkeye puts out(should be in your book) and for sure find out the watts the 2 fans put out to see if it will be too much of a load.

 

Puts out 250 watts.

Appreciate the info. I'm only looking at using 1 fan, as a puller thru the cooler, and it would also blow back on the engine.

 

Has yours ever given any signs of overheating? I rode mine up a very steep, rough, rock covered trail at a snails pace in 90 degree weather Saturday and mine never started to run poorly. On the same hill my sportsman would try to overheat.

How do you know if its running hot on an air/oil cooled engine with no temp light?

I don't know, and I don't think it is running "hot". Anything that can be done to reduce engine/oil temps in any engine, especially an air cooled one can't be a bad thing. I've got a chance to pick up a cooling fan off of a water cooled Suzuki quad cheap, and was just wondering if there was enough output to run it.

 

ours starts to run like the choke is on and looses power, When it cools down or we it some road it runs fine again. I too have the oil cooler and have considered a fan also, just havent found the right one. Could you send me some pics of your mounting did the factory hole etc work? I also made up a gaurd for the front too. If you are gonna look at a fan it may want to be waterproof.

I used the factory mounting holes to mount the cooler brackets to the frame. I replaced the bolts that hold the cooler to the brackets with threaded studs. A nut tightens the cooler down, and two more nuts hold the guard about an inch from the front of the cooler.

I wonder about the alcohol content in the gas. Heat will "boil" some of the alcohol out of the gas, and drop the octane rating. I had a car once that if you sat in traffic during HOT weather it would not have enogh power to pull itself.

The fan being off of a Suzuki quad I'm sure is "waterproof". As far as the fan, I'm really concerned about heat soak. The temp will continue to climb after you shut it off.

 

true it will heat up after the fan is off but could ou install a heat resistor with a sensor in the oil line somewhere? With the octane rating dropped would it run richer???

It might come with a thermostat, I can't tell from the picture. I might just hook it up to a switch and run it for a couple of minutes after I shut it off. Haven't decided yet.

If the octane rating dropped enough, it would be like "watered" down gas. I'm no expert, but from my experience with the car I had it will have very little power.
