Hombre S Space Cab 2WD V6-4.3L (2000)
Coolant Line/Hose: Service and Repair
Removal Procedure
Caution: As long as there is pressure in the cooling system, the temperature can be considerably higher than the boiling temperature of the
solution in the radiator without causing the solution to boil. Removal of the pressure cap while the engine is hot and pressure is high will
cause the solution to boil instantaneously - possibly with explosive force - spewing the solution over the engine, fenders and the person
removing the cap.
1. Remove the coolant from the radiator until the level is below the hoses being removed.
2. Loosen the radiator hose clamps.
3. Disconnect the radiator hoses from the radiator.
4. Disconnect the upper radiator inlet hose from the coolant outlet.
5. Disconnect the lower radiator outlet hose from the water pump.
Installation Procedure
Important: The 4.3L uses a spring-type (constant tensioner) clamp at the radiator hose connections. Install the hoses on dry, unpainted surfaces for
proper sealing.
1. Place the hose clamps loosely on the ends of the hoses.
