Service Procedure

Tool Required:

J 24460-01 Radiator Pressure Test Pump

A. INSPECTION

NOTICE: GASOLINE OR GASOLINE VAPORS ARE HIGHLY FLAMMABLE. IF AN IGNITION SOURCE IS PRESENT A FIRE COULD OCCUR. HAVE A DRY CHEMICAL (CLASS B) FIRE EXTINGUISHER NEARBY.

1. Disconnect negative battery cable.

2. Remove fuel tank filler cap to relieve any fuel vapor pressure.

3. Reinstall fuel tank filler cap and tighten until an audible "click" is heard.

4. Remove fuel vapor canister purge line from canister fitting marked "tank".

5. Disconnect radiator pressure test cap from Radiator Pressure Test Pump (Kent-Moore tool J 24460-01 or equivalent).

6. Insert threaded end of radiator Pressure Tester Hose into fuel tank vapor purge line.

7. Pressurize fuel tank and emissions system with 30 strokes of Radiator Pressure Tester Hand Pump. Pressure gauge on pump will indicate a low amount of pressure. Note location of needle in relationship to gauge and monitor for one minute. If emissions system, fuel tank filler cap and sender seal are correctly installed, there should be no loss of pressure.

NOTICE: DO NOT, UNDER ANY CIRCUMSTANCE, USE SHOP AIR HOSE IN PLACE OF RADIATOR PRESSURE TESTER HAND PUMP. OVER PRESSURIZING OF FUEL TANK OR EMISSIONS SYSTEM COULD LEAD TO SYSTEM LEAKAGE OR DAMAGE. IF AN IGNITION SOURCE IS PRESENT A FIRE COULD OCCUR.

8. After one (1) minute, slowly remove fuel tank cap while listening for pressure being released past the fuel tank cap threads.

- If release of pressure is evident, the seal ring has not been displaced. Go on to Step 9, stop at Step 12.

- If no pressure is detected when fuel tank filler cap is removed, it will be necessary to remove fuel tank to replace fuel tank sender seal ring. Proceed to Step B - Replacement Of Fuel Sender Seal Ring.

9. Disconnect Radiator Pressure Tester Hand Pump from fuel tank vapor purge line.

10. Reconnect fuel tank vapor purge line to fuel vapor canister.

11. Reconnect negative battery cable.

12. Install Campaign Identification Label.
