Cooling System Bleed Lines –

Correct Routing – Model Year Differences

Issue:

There are differences between the routing of the cooling system bleed lines between 1997 Model
Year vehicles and 1998 Model Year vehicles. Incorrect routing at the coolant reservoir
connections could lead to air remaining trapped in the cooling system, resulting in overheating of
the engine.

Action:

In case of a customer complaint of engine overheating on an XK8, check that bleed lines are
correctly routed as detailed below.
