It covers hose routing, tee fittings, bleeding air from the system, and a minor leak still unresolved. Best for owners doing this exact cab-heater retrofit themselves.
Posted by the Master Macgyver channel, an owner working through his own trial-and-error tractor project rather than a dealer or professional installer.
The correct part is Curtis Cab fitting 9HR0045, which attaches into the top of the water pump. It cost about $70 and was hard to source since it uses a non-standard thread.
No. The video shows this was a complete fail, it did not build enough pressure when tapped into the top radiator hose, so a dedicated Curtis Cab fitting was needed instead.
Run the tractor about five or six minutes, shut it off, fill and crack the radiator cap to release air, then repeat. It took about three cycles to clear the system.
