ISSUE:
Some 1995 MY Sedan Range vehicles specified on the included VIN list may have radiators assembled with drain plugs manufactured from a material which does not meet current specifications.
Refer to the included VIN list to determine which vehicles need to be checked. Under high ambient temperature conditions, the drain plugs may distort, leading to a loss of coolant.
ACTION:
The affected drain plugs must be replaced by those manufactured from the correct material. When possible, the drains plugs should be replaced during PDI. New vehicles that have a white label with a green letter "C" on the windshield have had the drain plugs replaced at the factory. DO NOT change the radiator drain plug on these vehicles.
On vehicles already in service, the drain plug must be changed at the first service opportunity.
REPAIR PROCEDURE
1. With the engine cold, slowly open the radiator cap to depressurize the cooling system, then close the cap.
2. Raise the vehicle on a lift and place a container under the radiator to catch the coolant. The amount of coolant released should not exceed 0.5 qt (0.5 I).
3. Install a new 0-ring, part no. JLM1499 on a new drain plug of the correct specification (part no. JLM 1340).
4. Remove the existing drain plug (Illustration 1) and immediately install the new drain plug. Torque the drain plug to 16 - 20 lb ins (1.8 - 2.2 Nm).
5. Discard the small quantity of coolant that was released while replacing the drain plug. Top up the cooling system using a 50:50 mixture of Jaguar Antifreeze, coolant, and corrosion inhibitor with plain clear water. Do not overfill.
6. Thoroughly clean up any spills to avoid causing any needless customer concerns of radiator, cap, or expansion tank leakage.
