2000 Cooling Fan on Rancher 350

While pulling out several loads of firewood over the past weeked, i noticed that the cooling fan wasn't coming on.

I checked the fan and have power to it but the fan is bad. After calling the local ATV supplier, I got a 270ish price. OUCH. It is a 2000 model - sorry, i hit -01 in the title.

Is the fan on the 4x4 and the 2x4 the same and if so, what years are in the range to interchange? I don't have a parts listing for the 4x4 but I have noticed that some of the bracketing is different.

THanks for any help,

Ted

I edited the title of your thread...

One thing you can do is check the OEM parts list for both machines. Sites like Motorcycle Parts, Motorcycle Accessories can provide a list of part numbers for you. If they both have the same part number, you nare golden.

Did you make sure the fan motor is actually bad, because on that model, the ECU uses the ground to turn the fan on and off. The power wire runs straight to the fan motor, but it won't work until the ECU grounds the circuit. You could have a bad fan control unit or a bad oil temp sensor.

Also, I think the fans are all the same on the 2000-2002 Rancher. Note that the 2wd, foot shift model doesn't have a fan, but all the other models do.

You only need two tools in life -- WD-40 and duct tape. If it doesn't move and should, use the WD-40. If it shouldn't move and does, use the duct tape.

Good evening Helmut, I was out of town on a jobsite for a couple of weeks and just now am getting back to check everything out.

You were right - It wasn't the fan. I had already changed the fuse and figured it blew when the fan died and fed back. Ok - i checked the power from the battery to the fan again and it was shorted out somewhere (i got intermitten voltage when i moved the harness) so I hooked a line from the battery to an inline (marine rated) fuse to the fan and then grounded the circuit and BUZZ - we got air flow. I'll check the oil temp sensor tomorrow and see what it shows. Basically - when the temp rises, closes the 'stat and then grounds the fan to run. That therefore means that the "thermostat" is in the ECU and not easily replaced.

Where's that darn manual!

Also, any reason behind the foot shift model not having a fan?

Thanks Helmut -

ted

You're welcome and there's a link to the 350 Rancher service manual in the manuals/schematics section of the forum.

I don't really know why the 2wd, foot shift models don't have a fan, I just know that they don't. They might figure the 2wd doesn't need a fan, but added it to the 2wd, electric shift models because of the ESP. I don't know, just a guess.
