2006 Pontiac GTO Problems

Leaking Water Pump May Cause Coolant Loss and Overheating

A coolant leak may develop from the water pump. This can result in an engine overheating condition. A leaking water pump will require replacement.

Check Engine Light Due to Gas Cap or Catalytic Converter

A loose or worn gas cap or a faulty catalytic converter are two common items which can cause Check Engine Light to illuminate.

Check Engine Light Due to Restricted Secondary Air Injection Check Valves

One or both secondary air injection check valves may become restricted causing poor air flow resulting in illumination of the Check Engine Light. It is often recommend to replace both check valves even if a fault code is set for only one bank of cylinders. Replacing only one valve may result in a return trip to the repair shop.
