Dismantling
1. Disconnect the negative battery terminal.
WARNING: Fuel vapors are highly flammable and toxic and explosive in confined spaces. Always have a foam, carbon dioxide (CO₂), gas or powder fire extinguisher on hand when working with fuel.

2. Loosen the 2 clamps and remove the air hose connecting the intake to the EGR valve.
CAUTION: Always plug the fittings and holes to protect the system from dirt.
3. Place rags around the fuel lines to collect any leaking fuel.
CAUTION: Fuel leakage is inevitable during this operation. Take safety measures to prevent fire or explosion.

4. Release the clamp from the inlet hose of the fuel cooling heat exchanger.
5. Release the fuel drain hose from the tank from the clamp.
6. Disconnect the 3 fuel hoses from the bimetal valve.
CAUTION: Before disconnecting or removing system components, make sure that the adjacent surfaces of the joints are free of dirt. Install plugs in the openings of the fittings and pipes to prevent dirt from entering the system.
7. Remove and discard the clamp securing the fuel heat exchanger inlet hose to the bimetallic valve.
8. Disconnect the fuel heat exchanger hose from the bimetallic valve and remove the valve.
Installation
1. Wipe the bimetallic valve and hose connection points.
2. Attach the valve to the fuel heat exchanger hose and secure with a new clamp.
3. Connect 3 fuel hoses to the bimetal valve.
4. Secure the fuel cooling heat exchanger inlet hose to the support clamp.
5. Secure the fuel drain hose into the tank to the support clamp.
6. Install the air hose onto the recirculation valve and secure it with clamps.
