PROBLEM:

COOLANT - CHANGE TO SPECIFICATION

Recent advances in coolant technology have resulted in a number of changes to the specified coolants for Rover / MG vehicles. This could result in confusion over the correct application and compatibility.

CAUSE:

• From the above VIN, Havoline XLC coolant has been introduced on production. • Clarification required for vehicles filled with previous coolant, Havoline AFC (Issue 1 of this bulletin referred). • Clarification required for vehicles prior to the introduction of Havoline AFC.

ACTION:

Havoline XLC is an Organic Acid Technology (OAT) product and is currently used in all Rover Group products to commonise coolant application. This product (orange / pink in colour) is an ‘extended life’ anti-freeze and summer coolant.

Service instructions For all vehicles from the introduction point quoted in AFFECTED RANGE , use only Havoline XLC (Unipart OAT) for top-up or refill, (see PARTS INFORMATION for part number details).

OAT coolant identification All vehicles production filled with Havoline XLC coolant have a yellow OAT expansion tank identification / warning label.

THE PRODUCTS QUOTED IN THE TABLE ABOVE ARE THE ONLY ROVER APPROVED COOLANT TYPES AND MUST NOT BE MIXED WITH ANY OTHER SPECIFICATION COOLANT OR MIXED TOGETHER.

Please ensure that all technicians and routine service staff are aware that use of non-approved coolant can have an adverse effect on cooling system performance and durability and that Warranty may be compromised.

For coolant renewal periods, refer to the appropriate Maintenance Check Sheet.

For future servicing convenience, it may be desirable to update the specified coolant in an earlier vehicle by replacing it with Unipart OAT (XLC), e.g. at the next change interval. This is permissible providing that the cooling system is first drained and flushed at low pressure as described in the Workshop Manual, repair number 26.10.01. When Unipart OAT (XLC) coolant has been added to such a vehicle it will be necessary to replace the existing black filler neck label with the OAT warning label coloured yellow, part number PAK100410A (see illustration). This will indicate that coolant specification has been changed.
