Program Timing
Affected vehicles are eligible for this program through July 31, 1996 regardless of mileage. (After July 31, 1996, a vehicle is eligible for this program if
it is still within basic vehicle warranty).
Affected Vehicles
Certain 1989 model Tempo and Topaz cars equipped with 2.3L HSC Engines built from 5131189 at Kansas City and 6122189 at Oakville through the
end of the 1989 model year and all 1990 through 1994 Tempo and Topaz cars equipped with 2.3L HSC engines that are currently registered in the
following states: Alaska, Montana, North Dakota, Minnesota, Wisconsin, Michigan (upper peninsula), New York, Maine, Vermont and New Hampshire.
Reason For This Program
On some of these cars, the positive crankcase ventilation (PCV) system may freeze causing the crankcase to pressurize which could force oil out of the
crankcase through the dipstick tube or past some other gasket or seal of the engine. This condition can occur during extended periods of highway travel
at extremely low ambient temperatures (-10F or lower). This combination of climatic and driving conditions is expected to occur only under unusual
circumstances in those states listed above. Engine damage could result.
Service Action
To correct this condition, dealers will install an improved coolant heated PCV system to reduce the likelihood of PCV freeze-up.
If an owner whose vehicle is not listed in OASIS believes his/her vehicle should have been included, or this condition is observed in a vehicle not
covered by this action, dealers are to contact their regional office for approval and submit the claim under this program to obtain reimbursement.
