Engine

Significant Problems Common problems on this vehicle are the failure of the Upper Intake Manifold and Gaskets and Oil Pan Gasket (3.8L). Failure of the Upper Intake Manifold and Gaskets allow engine coolant to leak into the cylinders. Failure of the Oil Pan Gasket allows oil to leak from the engine. An occasional problem with this vehicle is failure of the Catalytic Converter (3.8L VIN K engine only). A failed Catalytic Converter may cause the Service Engine Soon Light (SES) to illuminate or cause a lack of power. The cost to repair the Upper Intake Manifold Gaskets on vehicles without a supercharger is estimated at $421.00 for parts and $247.00 for labor. The cost to repair the Upper Intake Manifold Gaskets on vehicles with a supercharger is estimated at $430.00 for parts and $260.00 for labor. The cost to repair the Oil Pan Gasket is estimated at $46.00 for parts and $117.00 for labor. The cost to replace the Catalytic Converter is estimated to be $462.72 for parts and 52.00 for labor. All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.
