The only way I could think of getting fuel in the radiator in your 4104 is a cracked head.  If you have a fuel heater that works off the bus cooling system that is another possibility.

Manual

Bus runs great other than noticing the fuel in the cooling system.  Any tips to test for a cracked head  ?  I don't even know if there is a fuel heater.  I will look into that.  Thx for the help

If the head was cracked wouldn't there be a loss of coolant and possible overheating?

I meant a crack in the fuel galley of the head leaking into the cooling passage.
