Expansion Tank Replacement Method
Change

AFFECTED VEHICLE RANGE:
Freelander (LN)
All

SITUATION:

TIME STUDY EFFICIENCY

Methods engineers at Land Rover have recently studied the service process for renewal of the expansion tank assembly for Freelander models, and significant process changes have been made.
The changes, detailed below, refine and improve the process which allow the operation to be carried out more efficiently.

RESOLUTION:

EXPANSION TANK REPLACEMENT

Should it become necessary to remove an expansion tank assembly on a Freelander, refer to the procedure detailed in this bulletin. The coolant hose is now clamped to avoid coolant loss. With this method it is unnecessary to bleed entire cooling system saving time.

Repair time 26.15.01 has been reduced from 0.40 hours to 0.20 hours as the result of this change.

PARTS INFORMATION:
