1982 ESCORT WITH 1.6L ENGINE
LINCOLN MERCURY;
1982 LYNX WITH 1.6L ENGINE
The 1982 Escort/Lynx 1.6L engine is fitted with conical seat type spark plugs that require lower installation torque than the 1981 engines that use gasket
type plugs.
1981 - AGSP32 17-22 lbs-ft (gasket type)
1982 - AWSF32 10-15 lbs-ft (conical seat type)
NOTE: The two plug types are not interchangeable. The 1982 plug (AWSF32) has fewer threads and cannot be used to service the 1981 engines.
When changing spark plugs in an Escort/Lynx, be sure to check the following:
1. Vehicle Code Number: to determine which model year is involved.
2. Engine Emission Decal: to check the spark plug type number against the model year and confirm proper gap.
3. Plug type being removed: to confirm that the removed plugs match the plug type numbers from Steps 1 and 2.
NOTE:The EXP/LN7 in current production is not affected by this change and still use the gasket type spark plug (AGSP32) until further notice.
