SERVICE PRECAUTIONS
To prevent vehicle damage, always observe the following precautions:
- After servicing a hose, check for leaks before and after test driving the vehicle.
- Always use the correct size hose. Do not use standard sized hose in place of metric hose or vice versa.
- Always use the correct type of hose. Never use vacuum hose in place of fuel hose. Never use heater hose in place of PCV hose.
- When replacing hoses which are attached to the engine on one end and the frame or body on the other end, always leave sufficient length to compensate for engine movement (from torque).
