Bus Heater leaking coolant at front.
Ok I have an 01 IH genesis FE. I noticed last time I drove the bus the bus main heater had a small drip from the heater radiator. Iím not even sure if the heater works to be honest. BUT, I just dabbed some sealant on it and it seemed to help but now itís kinda pouring out. There seems to be a nice hole that is from the radiator and I was wondering if this line can just be pinched or capped?? Is it necessary for the engine to run?
Any help is appreciated, thanks.
