Installing cab heater in unit, would like pictures or exactly where factory hook up of hoses should be on the engine. Have had some general suggestions that to this point have not allowed for good circulation of hot water.
Appreciate the imsight.

Afternoon,
Does anyone have a DD Motorgrader (262 Diesel Engine) with a cab heater? My post has been viewed and I'm hopeful there is a unit out there that has a properly functioning heater.
My block will heat up just cant get circulation thru heater core.

Pull th heater core. If it's bad a good rad shop should be able to match it up..

Unhook both hoses from the heat, loop them together with a piece of copper pipe see if hoses get hot !

I have a brand new heater core assembly so its in good shape, I am challenged by the correct location around the water pump to make my connection. The grader is number 1575 so it has the cast wishbone coming from the bottom of the radiator to the water pump, then goes up to the casting that is fed under the thermostat by a 1" line. I have even Tee'd into this 1" line to try to achieve flow and wherever I am connected I have pressure and not developing a flow with the warm water in the block. There in lies my challenge, and why I am hoping a specific picture or diagram of the right connection can be found.
Thanks in advance for those who are reaching out to try to help me in solving this problem.
