Hello
I have bought a 2001 Ford F450 with 7.3 Diesel engine with an automatic transmission. I have drained all the old coolant out. However, I was only able to get approximately 6 gallons out of the system. I then proceeded to flush the engine multiple times with distilled water. I have replaced upper and lower radiator hoses, the heater hoses, thermostat, and thermostat housing and lower pipe on the water pump. When performing the flush and draining I remove both plugs on the engine and drain the radiator. Have never been able to to put more than 4 gallons of distilled water in at a time. I fill up to mid point between min/max on the bottle when it is cold. The last flush everything was clear, no green/yellow tint. I now am putting in the red ELC concentrate coolant and distilled water. Have only been able to put in 1.5 gallons of coolant and 1.5 gallons of distilled water. I then run the engine. Level is right between min/max in the bottle. I believe the engine has a 8 gallon coolant capacity. Any ideas why I cannot get more coolant in the system?
Thanks
