Colorado 2WD L4-2.8L VIN 8 (2004)
^
Some vehicles may intermittently set a DTC of P0442 or P0455, leak in the evaporative emissions system. In addition to checking the system
and performing the diagnostics as described in the Service Information for this DTC, the technician should be aware that some of the fuel caps
used on GM vehicles may not seal adequately to the filler neck if pushed down when being tightened. This may occur more often when this
cap is used on a vehicle with a steel fuel filler neck. The owner should be instructed not to apply a downward force to the fuel cap when
tightening.
Replacing Broken Fuel Cap
1.
Remove the fuel cap tether from the fuel filler pocket or fuel filler door.
2.
Remove the fuel cap from the fuel filler.
3.
If the fuel cap cannot be removed, remove the fuel cap ratcheting cover by releasing the four (4) tabs holding the cap cover to the lugged sealing
base.
4.
Position the radiator hose removal tool or similar type tool between the black cover and white inside body, and pry the cover over the retaining tab
by rotating the tool counter clockwise. Repeat, if necessary, on the 3 other locations around the cover.
