coolant leaking

TECHNICAL SERVICE BULLETIN
Chrysler Concorde/Dodge Intrepid Coolant Leak – 2.7L (1998-2004)
ASC PART NUMBER(S): WP-9103
CONDITION: A severe coolant leak from the water pump’s weep holes causes the coolant to destroy the
pump‘s bearing, as well as leak into the engine’s oiling system. Catastrophic engine failure can result.
CAUSE: This engine’s water pump is buried beneath the timing cover since it is internally driven off the
engine’s timing chain. Since the front of the pump has direct contact with the engine’s oiling system, the
weep holes have been rerouted. Leaking coolant is channeled back through the pump and into the
engine block. Therefore, if the water pump seal fails, the noticeable leaks will occur as coolant exits the left
side of the engine block just below the thermostat housing and, if severe enough, from the rear of the
engine block, towards the top.
CORRECTION: Be aware of the potential leak points and do not ignore the signs of a leak. It also is
recommended that the water pump be changed whenever servicing the timing chain and/or internal
timing components.
