electric fan?

rwonder · #1 06-28-2013, 08:58 PM

Is there anyone on here that has put an electric fan on a diesel super? Was wondering if we could get more air through the radiator going this route? Maybe this has been discussed, and if so I apologize for bringing up an old issue. My 1572 runs with the needle on the temp gauge just under the red area. everything is as clean as it can possibly be. If anyone has tried this with good or bad results, your input would be appreciated.

Thanks

if your running hot, you should check your thermostat. could be stuck closed.

yes, I guess that would be a good item to try. Not going to break the bank, so just try a new one and see if it helps.

Thanks

For the size of electric fan you would have to get to fit in the small area.... I HIGHLY doubt it would move as much air as the engine driven one. Plus... who wants to spend all that time wiring into the ign, or hooking up a thermostat to run it just to gain.........nothing.

When I purchased my 782d; The po had installed an electric fan, removed the fan shroud, and removed the thermostat.
It accomplished nothing.
I finally found all the parts for the fan, fan jackshaft, and fan shroud.
Put in a new thermostat. Then removed the radiator and had it cleaned.
It runs well now and no overheating.
Just my thoughts on this. Radiators do collect silt and need to be cleaned

I don’t think the alternator would handle the load. Try some redline water wetter in the radiator.

yes, I had the thought about the alternator not having enough to handle the fan. I went out to look at the thermostat today and after realizing how hard that upper radiator hose is, I am not going to touch that until I have to. The wetter water sounds like an item to try. At least won't have to touch that hose for now.

I've used this stuff in my race car and it was good for about 10 degrees I put some in my 2182 and it seems to run cooler. Got it all the way up to 185 the other day running the crap out of it on a hot day with the 60" Haban. Used to get close to 200.

I agree on double checking everything. Neither of my diesels run hot even during the summer under load of mowing. I religiously clean the radiator and the engine compartment. The BRS has a little too much fluctuation in temp so a new thermostat is on the way for it.

I find that the diesel super (1572 and 782D in my experience) will run hot with extending idling. Bringing up the engine speed will increase both water flow through the radiator and air flow across the radiator. I had a similar problem overheating with my 782D. The radiator was all plugged up with deposits. I went to the auto parts store and ran some heavy-duty radiator cleaner through it so it was as clean a a whistle. A lot of the over heating problem went away except for the extended idling running hot. I also switched over to Evans water-less heavy duty coolant to avoid corrosion and cylinder liner cavitation. It is also a lifetime coolant. Been running it for about 6 years now.
