START BY:a. remove water temperature contactor1. Drain the coolant from the cooling system, and disconnect the regulator housings from the radiator. 2. Remove the bolts and retainers to remove tube (1) from the engine. 3. Remove the clamps, and remove turbocharger oil line (2) from the engine. 4. Disconnect tube assembly (3) from the regulator housings and the aftercooler adapter. Remove tube assembly (3) from the engine.5. Remove bolts (4) that hold the regulator housings to the brackets. 6. Fasten a hoist to the regulator housings with tooling (A) as shown. Remove bolts (5), and remove the regulator housings from the engine. The weight of the housings is 63 kg (139 lb.). 7. Put the regulator housings on blocks as shown. Fasten a hoist to housing (6) with tooling (A). Remove bolts (7), and remove housing (6) from the water temperature regulators. The weight of housing (6) is 20 kg (44 lb.). 8. Remove water temperature regulators (8) from the housing. 9. If necessary, remove seals (9) from the housing.10. Remove ferrule (10) and the ball from the housing if necessary.Install Water Temperature Regulators
1. If the ball and ferrule were removed, install the new ball and ferrule (1) in the housing. Make sure the open end of ferrule (1) is toward the outside of the housing. Ferrule (1) must make contact with the bottom of its bore.2. If the seals were removed, install the new seals with tool group (A) in the housing. Make sure the lip of the seals is toward the inside of the housing.

3. Install water temperature regulators (2) in the housing with the spring up as shown. 4. Fasten a hoist to housing (3) with tooling (B). Put the gasket and housing (3) in position on the water temperature regulators. Install the bolts to hold the housing in position. 5. Use tooling (B) to fasten a hoist to the regulator housings as shown. Put the gaskets and regulator housings in position. Install the bolts to hold the regulator housing to the water manifolds. 6. Install bolts (5) to hold the regulator housings to the brackets.7. Install tube assembly (4) between the regulator housings and the aftercooler adapter. 8.
