Put the UTV with the front end up at a 45 deg angle and loosen the cap with the engine running and run the engine and rev it up every so often for 10 to 15 minutes. This will remove trapped air in the engine and the system. Also check to make sure the radiator is clear and the fan is coming on also make sure after it is warmed up that there is flow in the radiator if if there is no flow you need to test or change out the thermostat.....

Just to add you might want ot examine your rad cap it might be busted.

Why not just get a new relay? If you want to run it all the time just go to the switched terminal next to the battery. It probably won't hurt anything to run it all the time (mine runs a lot during the summer months). I'd put a on/off switch on the dash so you can at least manually control the fan's operation.

It wont do him any good to hard wire the fan into a switch on the dash if he is not getting the proper flow. Both of you have good thoughts though.

I have been giving it some thought on a fan bypass on mine but yes if there is no flow or the radiator is plugged up like mine gets now and then with the dead wild flowers getting sucked in it that will not fix the problem. I had a boil over problem that happened last trip and and so fare the problem has not been found on why it did it. At this time I am not sure if it was a stock thermostat or the PCM did not receive the Fan on command from the temp sensor or it was a stuck fan. Air trapped in the system would cause the fan not to come on and there is a procedure to purge the air and most of it was stated on my first post with the exception of removing the bleed screw on the thermostat housing.

As for a fan bypass switch, There may be a problem since the PCM senses fan load and it may set a trouble code light if it tries to turn on the fan while the bypass switch is in the on position. this will be tested next week when I try to do one on mine. this may only be an issue on pre 07 models that use a PCM and the newer one have changed out the system and may not include that function...

Just an update to the fan over ride switch.....

I did test and then installed the fan over ride switch the other day and so fare it has not freaked out the PCM and has not set off the trouble light.........

If nothing else works you can always try this. Your overheating issue will be OVER!

ENGINE OIL COOLER...

BYPASS THERMOSTAT (40% more flow) Similar to what Polaris is now doing on the 2011 Ranger
Here is the link...

Clint Berry Racing made this radiator for me. It is a direct bolt in replacement, and uses the stock fan.

The stock fan is a very good one, made by spall (They make all the Ferrari cooling fans)
