Start By:
- Remove the heat exchanger. Refer to Disassembly and Assembly, "Heat Exchanger - Remove".
- Remove the water temperature regulator housing. Refer to Disassembly and Assembly, "Water Temperature Regulator - Remove and Install".
- Remove the turbocharger. Refer to Disassembly and Assembly, "Turbocharger - Remove".
Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove cooling system pressure cap slowly to relieve pressure only when engine is stopped and cooling system pressure cap is cool enough to touch with your bare hand. Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns. Cooling System Coolant Additive contains alkali. Avoid contact with skin and eyes. |
