I found a old home made cab for some unknown tractor for $20 at a swap meet. I fixed it up and modified it to fit my 445. Now I'm adding heat. I've seen people "T" into the 3/8" bypass hose for the supply and then "T" the return into the Lower Radiator hose. I was wondering if I could just cut the 3/8" bypass hose and route it to the heater core and return to the other side of the 3/8" bypass hose. This way I'm only cutting one hose. It seems to me the only downside to this is that I won't be able to shut off the heat. What does this bypass hose even do?
