[M35 overheating]

Scotty mn35 Just been reading alot of your comments and treads, seeing if you have any of your cooling mods laying around..... and some pointers on bleeding the cooling system... I've tried a few times no luck care only over heats in hot weather, I've ordered new water pump thermostat and looking at replacing the radiator just for peace of mind but still sounds like from what I read it's air block..... only started happing after I blue the heater bypass hose on the front of the motor..
