b. Carefully remove radiator cap.
c. Remove radiator drain plug.
2. On 1.8L/4-107 engines, when removing upper radiator hose, mark hose clamp in relation to hose for assembly reference.
3. On all models, before disconnecting high pressure fuel line, relieve fuel pressure as outlined in ``Fuel Pressure Release'' found in Maintenance Procedures.
4. Remove delivery pipe, fuel injector and regulator as an assembly.

INSPECTION

Inspect intake manifold and air intake plenum (if equipped) as follows:
