Gator Overheating, fan doesn't come on

[dnw64]

I recently acquired a 2000 TH6X4 Diesel Gator.

A little rough, just under 2000 hours, manual dump (I need to work on that - the wife can't operate the dump even when empty).

After using it for 20 mins to a half hour the temp light came on. Turns out the cooling fan isn't working. To trouble-shoot, I'm wondering how it's supposed to function - is it thermostatically controlled or is it just supposed to run whenever the ignition is on?

BTW, the thing is a beast! Especially with the differential locked!! Just don't bother trying to steer it with the differential locked...

I don't know these things. But does the fan spin free? Do you know where the thermostic electric switch is for the fan? If you short that, the fan should run. There may be a relay too. How is the coolant level. On some UTVs, the cooling system can get air pockets and if the thermoswitch is not submersed in liquid, it may not operate.

You might consider purchasing a OEM Tech Manual for your Gator. They can normally be found on eBay.

Great idea. Thanks!

I’m fairly sure the fan is controlled by thermostat AND runs when your ignition is on.

Holy Moly are those things expensive! Up to $200 for a new one.

Got a PDF version for $5.

One question answered:

I was wondering if they bothered with thermostatic control since there is never any natural airflow over the radiator.

My gas version was controlled by a temperature

If u don稚 want to spend money, just wire directly to ignition or a switch (that you don稚 forget!)

If the ICE gators are the same as my Electric Gator, you could be in for a terrible shock, anytime you want parts. I thought, maybe it was just mine, since it comes more under the TURF product range.

Just looked up some records. A short splined axle shaft for my E-Gator (maybe 3/4" O.D. ) costs $2217.00 CDN from the dealer. Fortunately, I had a whole spare transaxle.

Um, I guess I would be scrapping mine! That's ludicrous!!

the fan sensor is located in the radiator. Neighbor has one(late 90s) it got to overheating because the water pump crapped out. Part diagrams are available on the internet. The gas model cooling systems are a little different. There are some Youtube videos dealing with the diesel 6x4 too. The radiator is under the passenger seat and that big plastic panel has to com off, you have to pull the parking brake handle up to remove the panel. Radiator cap on his was in the upper radiator hose. later models may differ. One other thing, when filling cooling system make sure to get all the air out of it.

Many times there is a thermo-switch on the radiator that turns on a relay that then runs a fan. As stated before, if the water pump is not circulating the hot water, the fan never turns on. So, is your thermostat opening? Is the water pump working? Is the thermo-switch switching? Does the relay work? Does the fan work?

Lots of good questions. I was just hoping to get some info about the way the system is SUPPOSED to work so I would know how to proceed. As I previously mentioned, I thought maybe the fan might supposed to just come on when it starts, because there is ZERO airflow over the radiator from movement.

If I remember, it does not come on until up to temp and then interment after that when needed
