175 cooling fan

[Jason S.]

Sometimes when baling hay my 175 runs warmer than I think it should. The radiator fins are clean...water pump has been changed and it runs around halfway or a little more on the gauge....and it is a Massey gauge. I was looking on here and noticed they show a 6 blade fan...mine is a 4 blade. Which is it supposed to have for a 175 8 speed diesel? Thanks for all your help.

I have 3 175's and they all have the 4 blade fans.

Hi Jason, whilst the fins might be clear the tubes might be partially blocked and that would cause a higher running temp. Baling should not necessarily cause the tractor to run hotter as it does not have a heavy power requirement. Have you tested the thermostat? It would be worth removing the thermostat and running the tractor in similar conditions without it or take a chance and replace it.
It is probable that your fan can only be fitted one way but its worth checking.
Do you have a A4.236 engine? Several fans are listed in the Bepco book. For the 175 with the 236 a 16" metal two piece is listed.
A six-blade is listed for 236 engines but does not show it for the 175.
There is also aplastic 8 blade fan listed for all 212, 236 and 248 engines so the pulley mounting would appear to be the same on all of these.

I should have said round baling... I have thought about replacing the thermostat but it doesn't run hot pulling anything else. The dealer I got the tractor and baler from said that tractor should have plenty of power for that baler. I can't find anything wrong with the baler that would cause it to pull the tractor so hard that it would run hot. The baler is a 504G Vermeer. The dealer did tell me to check the air intake hose and see if it is collapsing...it doesn't seem to be collapsing to me so I do know what to try next.

You may check the radiator cap if it opens
a the proper pressure if it does not it may be the cause of overheating. If you bring it with you usualy the dealer will test it for free with a cap tester.

If coolant has a rusty color then:
Radiator and block may be dirty inside with rust
and old antifreeze byproducts you may buy radiator/block flushing product at auto parts and replace the old antifreeze. Good quality antifreeze/coolant is better than plain water for cooling.

I do not remember hoses placement on 175 is it possible that the lower radiator hose collapse when running ?

My 2¢

I have always seen areas of the radiator clear where the fan sucks the air in the center. Check your corners and blow it out with air. With the engine cool, flush it out with a garden hose. I think you will be amazed with the junk you will wash out. It helps alot!

Mine has 4 blades also. The only time it will get that warm is when I use a finish mower on a hot day thru the thicker stuff.

I think you need to take a closer look at the radiator... Same thing was happening to my MF35 and I couldn't figure out what was going on... Fortunately, my dad taught me to try the simplest/cheapest things first... Knew I had found the problem when I could only see through about 50% of the radiator... blew out the debris (from back to front) with an air-hose... tractor runs cool-as-a-cucumber now...
