White 135 Field Boss

old horse power · Mar 23, 2015

Having trouble with the heating system on a 135 field boss. Still a little chilly here in mornings. Changed thermostat and water pump. Seems to not pump any water up to the core in the cab ?
Also took the valve out in the cab for heat control cause it was rusted out around the hose coupler so just spliced the hose together for free flow.
Any ideas where to go next ?

Well it could be that the heater core is somewhat plugged for one if it has a air BLEND door it may be sticking open a little and allowing more cold air not to pass thru the core. Or it maybe like the one on my buddy's New Holland skid steer that ya need to BURP once in a while as it gets and air lock just before the core . When it does get air locked i loosen the clamp at the core and shove my hose removal tool down beside the fitting with the engine running at over half throttle and it will BURP the air out and then it will start moving water thru . This happens when he removes the Rad. cap to check or add fluid .

Seems to flow through when I put a hose to it.
Would it work on the bottom hose the goes back to the rad. ?

Im not sure if yours is the same as my cousins 135 but they have a valve up near the water pump to shut off the coolant back to the cab. Was a factory thing to my understanding. Is it possible yours is plugged or restricted? There were times even after they opened it there still wouldn't be heat or hardly any as it had an air pocket in it. I believe they had to give it a small shot of air in the radiator.

Never crossed my mind about the valve going bad. Thanks!!
