REMOVAL & INSTALLATION
See Figures 1 through 13
All gasoline-engine equipped trucks use a cross-flow radiator. In this type, the coolant flows horizontally from a radiator inlet tank to a radiator outlet tank.
Most diesel engines are equipped with copper core downflow (vertical flow) radiators. The 7.3L diesel engine copper core radiator was phased out during the 1995 model year and was replaced with an aluminum downflow radiator.
- Drain the cooling system.
- Disconnect the transmission cooling lines from the bottom of the radiator, if so equipped.
- If applicable, use a suitable prytool (see photo) to remove the push-in fasteners that retain the air intake duct, then remove the duct from its mounting on the radiator support.
- Remove the retaining bolts at each of the four corners of the shroud, if so equipped and position the shroud over the fan, clear of the radiator.
- Disconnect the upper and lower hoses from the radiator.
- Remove the radiator retaining bolts or the upper supports and lift the radiator from the vehicle.
- Lower the radiator into the vehicle. Install the radiator retaining bolts or the upper supports.
- Connect the upper and lower hoses at the radiator.
- Install the shroud, if so equipped.
- If applicable, install the air intake duct.
- Connect the transmission cooling lines at the bottom of the radiator.
- Fill the cooling system.
