Subject:
FUEL FILLER CAP CROSS THREADING
Model and Year:
1989-91 CAMARO
TO:
ALL CHEVROLET DEALERS
Condition:
Comments of fuel odor and rear quarter panel staining in the area of the fuel filler door may be received on 1989-91 F-cars. This
condition has occasionally been noted after the vehicles fuel tank has been over filled, but does not occur after every refilling.
Cause:
Inadvertent cross threading of fuel filler cap may provide false indication (clicking/racheting sound) that the cap has been properly
installed. During proper installation, the cap will rotate freely for at least 2 (two) complete revolutions prior to sealing of the cap
contacting filler neck seal surface. Additional rotation of the cap will generate a clicking/racheting sound.
Correction:
Replace existing fuel filler cap with new cap, P/N 10164142. The lead and thread characteristics of the new cap have been
modified to minimize potential for cross threading.
Parts are currently available from GMSPO.
