There are two ways to go about this task: either remove the engine from the
car, or remove the radiator, grill and any other supports which are directly in
front of the engine. If the second altern ative is chosen, you may have to
disconnect the motor mounts, and raise t he front of the engine. This will give
you the necessary clearance to remove the camshaft from the engine.
1. Drain the engine oil an d the cooling system. Remove the radiator.
