Before removing a cylinder head, perform a compression test and/or leakdown test to verify is head removal is required.

NOTE
With some minor variations, this procedure can be used on both the left and right cylinder heads.

1. Raise and safely support the vehicle.
2. Drain the engine coolant and the engine oil. Lower the vehicle.
3. Remove the upper and lower intake manifold using the procedures found in this section.
4. Remove the rocker arm and pushrods using the procedures found in this section.
5. Remove the exhaust crossover pipe.
6. Remove the engine mount strut bracket.
7. If removing the left side (front) head, remove the dipstick tube.
8. Tag for identification, then remove the spark plug wires. Remove the spark plugs. Please see for more information.
9. Remove the exhaust manifold using the procedures found in this section.
10. Remove the eight cylinder head bolts, then remove the cylinder head. There are locator pins that align the head to the block. Pull upwards on the head to disengage the pins, then remove the cylinder head to a suitable work area.
11. If the head is be overhauled, remove any remaining components such as the engine lift hook, the fuel line bracket bolts, the engine coolant temperature sensor, etc., as required.
