The coolant may be hot. Use caution when
removing hose(s) to prevent contact.
3. Remove clamps from each end of the Hose
and remove Hose.
INSTALLATION PROCEDURE
IMPORTANT
Coolant hoses are specifically designed for their
application. DO NOT use hose material or length
other than the OEM specified parts. DO NOT mix
the inlet or outlet ends of the Hose when reinstal-
ling.
1. Slide Clamps over each end of the Hose.
2. Insert Port Fittings into each end of the Hose.
3. Slide Hose Clamp to a position approximately
½” from the end of the Hose and tighten.
4. Refill with coolant.
5. Start engine and let run until it reaches operat-
ing temperature.
6. Check for leaks. If leaks are detected, make
repairs.
7. Stop engine and allow to cool. Check coolant
level and add coolant as necessary.
XXI. FUEL VAPOR HOSE
REMOVAL PROCEDURE
1. Relieve the LPG fuel system pressure. Refer
to XVIII. LPG FUEL SYSTEM PRESSURE
RELIEF.
2. Disconnect negative battery cable.
3. Remove Retaining Clips securing Port Fittings
on both ends and remove with Hose attached.
4. Remove Hose Clamps.
5. Remove Port Fittings from Hose.
Residual vapor pressure will be present in
the fuel system. Ensure the work area is
well ventilated before disconnecting any
fuel line.
IMPORTANT
Hoses are designed for specific applications. DO
NOT use Hose material or length other than spe-
cified by the OEM. DO NOT mix the inlet or outlet
ends of the Hose when reinstalling.
INSTALLATION PROCEDURE
1. Slide Hose Clamps over each end of the Fuel
Hose.
2. Insert Port Fittings into each end of the Hose.
3. Slide each Hose Clamp to a position approx-
imately ½” from the end of the Hose and
tighten.
4. Lightly lubricate new O-ring with Vaseline or
petroleum jelly prior to installation.
Contamination of the HEGO sensor can re-
sult from the use of an inappropriate RTV
sealer or silicone spray products. Do not use
silicone sprays or hoses which are assem-
bled using silicone lubricants. Always use
“oxygen sensor safe” RTV sealant for repair
procedures. Silicon contamination will cause
a high but false HEGO signal voltage (rich
exhaust indication). The ECM will then re-
duce the amount of fuel delivery to the
engine, causing a severe driveability prob-
lem. If silicone contamination is suspected,
remove and visually inspect the sensor ele-
ment. If contaminated, the portion of the
sensor exposed to the exhaust stream will
have a white powdery coating. Always be
sure to eliminate the cause of contamination
before replacing the sensor.
5. Reinstall Hose at both ends and secure using
Retaining Pins.
6. Reconnect negative battery cable.
7. Open LPG tank valve.
8. Turn Key to the ON position for several
seconds, then turn back to OFF. Check for
leaks at the inlet and outlet fittings using a
soapy solution or an electronic leak detector.
If leaks are detected, make repairs.
9. Start engine and check for leaks.
10. If a DTC code is found, refer to the Electrical
Section for further diagnosis.
