Hi I’m doing a kubota swap in my 751. I’ve got a heater core in my cab, can’t remember which side hose was the feed or return. Also not sure where to hook those hoses up on the v2203. There is one male sticking out of the coolant tube above the pump drive belt area, and then one top of the water pump and one coming out of the thermostat housing. Common sense says to connect the pump to the housing with a hose but that doesn’t leave me with but one connection for the heater core. Thanks guys Basically anyone with a 753/763/773 with a v2203 should be the same
