Issue:
*A concern has been identified on a number of 2004-05 MY XK Range vehicles within the above VIN range.* A failure can occur at the outer crimp face of the oil cooler feed pipe/hose that leads from the engine to the intermediate connector. The same problem can occur on the oil cooler return pipe/hose leading from the intermediate joint back to the engine. These conditions can result in the possibility of engine oil loss and reduced engine performance.
Action:
*Inspect, at the first available opportunity, all 2004-05 MY XK range vehicle within the above VIN range.* Check the feed hose/pipe leading from the engine to the intermediate connector and the oil cooler return pipe/hose from the intermediate connector back to the engine for a date code of 43 03.
If the date code is illegible, not present, or reads 43 03 on either the engine to intermediate connector oil cooler feed pipe/hose or the oil cooler return pipe/hose, both pipe/hoses must be replaced.
