It is time for some general maintenance on my 2002 Ford F250 and the 7.3 Powerstroke diesel engine. The 7.3 has developed a coolant leak at the thermostat housing, which is not uncommon for these trucks. We install a new billet thermostat housing, Ford OEM thermostat, as well as an upgraded upper radiator hose for the 7.3 diesel engine. With these maintenance upgrades and changes, we should have a leak free system that lasts a long time. Our video details all the steps necessary to complete this maintenance hassle free.
