Subject: | Coolant Leak from Water Pump- 3.8L (Reposition Inlet Hose) |
Models: | 2007 Buick Lucerne with 3.8L Engine |
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Coolant leak from the water pump.
The water pump inlet hose may not be squarely installed onto the water pump allowing the clamp to not be positioned firmly over the machined area of the water pump. This is identified easiest when viewing the hose from underneath with the vehicle on a lift. Loosen the hose clamp and reposition the hose as necessary. The clamp is adhered to the hose.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
