Repair operations possible with the engine in the vehicle

1. Many major repair operations can be accomplished without removing the engine from the vehicle.

2. Clean the engine compartment and the exterior of the engine with some type of degreaser before any work is done. It will make the job easier and help keep dirt out of the internal areas of the engine.

3. Depending on the components involved, it may be helpful to remove the hood to improve access to the engine as repairs are performed (refer to Chapter Body if necessary). Cover the fenders to prevent damage to the paint. Special pads are available, but an old bedspread or blanket will also work.

4. If vacuum, exhaust, oil or coolant leaks develop, indicating a need for gasket or seal replacement, the repairs can generally be made with the engine in the vehicle. The intake and exhaust manifold gaskets, oil pan gasket, crankshaft oil seals and cylinder head gasket (2009 and earlier models only) are all accessible with the engine in place.

5. Exterior engine components, such as the intake and exhaust manifolds, the oil pan, the oil pump (2009 and earlier models only), the water pump, the starter motor, the alternator and the fuel system components can be removed for repair with the engine in place.

6. Since the cylinder head can be removed without pulling the engine (2009 and earlier models only), camshaft and valve component servicing can also be accomplished with the engine in the vehicle. Replacement of the timing chain and sprockets is also possible with the engine in the vehicle (2009 and earlier models only).
