Report: Persistent Coolant Loss Due to Small Leak at Coolant Reservoir
Jaguar S-Type Problem
Heating & Air Conditionings Affected: 3.0L V6, 4.0L V8
Average Mileage: 86,675 mi (33,000 mi - 150,000 mi)
The plastic coolant reservoir is prone to leak. The reservoir can mysteriously lose coolant or coolant may pool under the engine compartment. If this occurs, the coolant reservoir should be inspected for cracks. If leaks are neglected, the reservoir may fail and cause the engine to overheat.

Persistant loss of anti freeze, checked hoses, dealer said I needed a new high pressure hose, $400 later I still had the leak. I found that the bottom of the plastic reservoir was cracked. I purchased one from autohausaz.com for $45 and replaced it myself.

This just happened on my 2006 S-type. Must be design or part flaw.

Same deal. Coolant backflowing, no internal heat/defrost, etc. and my performance has dropped considerably. "Trusted" mechanic quoted me $800 to replace reservoir and lower PCV valve grommet assembly. Looks like I can get the parts online for $110 and take the hour necessary to replace it myself, unless anyone has info on something I'm missing here?

My jaguar overheats and the antifreeze comes out through the hoses.
