The replacement of the
Radiator inlet hose begins with draining part of the cooling system for models lu3, lr4, lm7, and lq4. Position the hose pliers (J 38185) at the Radiator inlet clamp before moving it to the position at the
Thermostat Housing. You must remove the Radiator inlet hose from its positions at both the Radiator and the Thermostat Housing. Begin by replacing the Radiator inlet hose after you remove the old one by securing it first onto the Radiator before moving it to the Thermostat Housing. The hose pliers (J 38185) should be used to install hose clamps at the Thermostat Housing and the Radiator inlet housing before filling the cooling system.
