Attention! Gasoline is highly flammable. Therefore, additional precautions must be taken when working on any honor fuel system or EVAP system. Do not smoke or allow open flames or unprotected light fixtures near the work area. Do not work in rooms where gas appliances are present (e.g. water heaters or clothes dryers). Since gasoline is a carcinogen (contributes to the development of cancer), try not to allow fuel to come into contact with exposed areas of the body. Wear fuel resistant gloves. In case of contact with fuel on the skin, the affected area should be washed immediately with soap and water. Wipe up spilled fuel immediately and do not store fuel-soaked rags where they could ignite. Wear safety goggles when doing any work on the fuel system. Keep a class B fire extinguisher handy at all times.
Purge valve
Note. On four-cylinder models, the purge valve is mounted on the baffle behind the throttle body. On V6 models, the purge valve is located on a support bracket bolted to the front end of the intake manifold. The accompanying drawing in this paragraph shows the purge valve used on V6 models, but the purge valve used on four-cylinder models is similar except for its location.
