CAMPAIGN: INCORRECT ENGINE OIL DIPSTICK
Subject: INCORRECT ENGINE OIL DIPSTICK
Models: 1993 Chevrolet Caprice and Buick Roadmaster Equipped with 5.OL (L03) or 5.7L (L05) Engine (Arlington Only)
TO: ALL GENERAL MOTORS DEALERS:
General Motors of Canada Limited has determined that certain 1993 Chevrolet Caprice and Buick Roadmaster model vehicles equipped with 5.OL or 5.7L engines (RPO's L03 and L05) built at the Arlington Assembly Plant (VIN Code R) have engine oil dipsticks that are approximately 20mm longer than the correct engineering specification. This condition would cause a properly filled engine to indicate an over filled reading on the dipstick. Draining the oil to correct this condition would result in the engine oil being approximately one liter low.
To correct this condition, a new dipstick with the correct length, will be sent to all owners of record. Additionally, those owners with under filled engines will be given the option to come to their dealerships to have the engine oil level inspected and adjusted as necessary.
VEHICLES INVOLVED:
Involved are certain 1993 Chevrolet Caprice and Buick Roadmaster model vehicles built at Arlington (VIN Code R) built within the following VIN breakpoints:
Model Year Model Plant From Through ---------- ----- ----- ---- ------- 1993 Caprice Arlington SOP PR100458
1993 Roadmaster Arlington SOP PR403524
All affected vehicles have been identified by the VIN listing provided to involved dealers with this bulletin. Any dealer not receiving a listing was not shipped any of die affected vehicles.

Owners of vehicles who want to have die engine oil level inspected will be instructed to make an appointment with the dealer to have this service completed.

Dear General Motors Customer
General Motors of Canada Limited has determined that certain 1993 Chevrolet Caprice and Buick Roadmaster model vehicles were built with the engine oil dipstick longer than required. This condition would cause a properly filled engine to indicate an over filled reading on the dipstick. Draining the oil to correct this condition would result in the engine oil being approximately one liter low.
To correct this condition, a new dipstick with installation instructions has been mailed to you with this letter. You may install the dipstick or ask your dealer to do die service. If additional engine oil is needed after the new dipstick is installed, you may obtain the oil from your dealer at no charge.
If you have sold or traded your vehicle, please forward the dipstick to the new owner. If this is not convenient to you, please deliver the dipstick to your nearest GM dealer. DO NOT RETURN TO GENERAL MOTORS.
We appreciate your cooperation and are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
INSTALLATION OF ENGINE OIL DIPSTICK
1. Open your vehicle's engine compartment hood.
2. Locate the engine oil dipstick ("ENGINE OIL" painted on dipstick handle) to the left of the air cleaner when looking at engine from the front of vehicle.
3. Remove old dipstick from vehicle. Place in shipping tube and dispose properly.
4. Wipe the new dipstick clean and insert all the way into the engine dipstick tube.
5. Check engine oil level.
a) Pull out the dipstick and clean it with a paper towel or cloth.
