I had to modify my radiators upper inlet so I could route a hose around the fan. So the way things are the radiator cap is going to be lower than the top of the motor so I will get an air pocket. I can buy a hose with a radiator cap built in it but then I'll have two caps. What if I weld in a bung with a pipe plug on my thermostat housing? I could then pull the plug and top off the system at its highest point. What do you all think? The thermostat housing is in a straight line from the inlet pictured below.
