Confirm if coolant is visibly dripping from the weeper chamber. 2.Root Cause identification The weeper chamber is designed to collect small amounts of coolant (< 3 ml/h) that pass through the dynamic seal. Red traces or shadows around the chamber may appear during initial operation due to seal adaptation or vapor condensation. These traces are not necessarily signs of a leak. Continuous dripping of coolant, however, indicates a malfunction. 3.Service Repair Procedure Lift the vehicle using an elevator. Verify if coolant is actively dripping from the weeper chamber. Run the engine at idle, alternating speed between 2000 4000 rpm for 15 minutes. Observe the weeper chamber during this test: If coolant continues to drip: Replace the water pump (possible permanent damage to the dynamic seal). If dripping stops: No further action is needed; the vehicle can be returned to the customer. 4.Clarify Leak Sources Do not confuse leaks from: The Press-In-Place rubber gasket (between water pump and engine block), or The inlet pipe nipples with leaks from the weeper chamber.

Before replacing this part due to Engine Light On with P1CEA (Boost Side EVAP Purge System Performance), check for: 1) Improperly connected or kinked/pinched Purge Hoses at the Ejector Tees on the Air Box or Duct. 2) Improperly connected or kinked/pinched Purge Hose at the Purge Solenoid or OBD Valve. 3) Improperly connected or kinked/pinched Purge Hose at the Intake. 4) Check for the correct Purge Hoses installation.
