Freelander - Poor Heater Performance
Bulletin Number - 0018
Issue - 1
Date - 15.08.2001
Model - Freelander
Affected Range - All diesel engine vehicles fitted with Fuel Burning Heater (FBH) in VIN ranges: Freelander 1A 576764 to 1A 599999 & 1A 300000 to TBC
POOR HEATER PERFORMANCE FROM COLD ENGINE START UP
The customer complains of excessive delay in obtaining satisfactory heater output following a cold start.
Due to an excessively wide sensing tolerance, the outside air temperature sensor may not activate the FBH until the ambient temperature is as low as 0° C. This renders the FBH inactive at temperatures where its additional heat output would be beneficial in assisting with engine and heater warm up.
On customer complaint, replace the outside air temperature sensor with the new narrow range sensor detailed in PARTS INFORMATION.
Refer to Workshop Manual repair number 80.40.31 for repair procedure, noting the following:
- Position sensor to bracket with electrical connection uppermost.
- Fit rubber / nylon washer to sensor with rubber face next to bracket.
- Fit multiplug to sensor and push firmly together. Ensure that the multiplug latches to sensor.
