A tool set containing a valve spring compressor (J 43649), a Valve Stem Oil Seal remover (J 36017) and both a Valve Stem Oil Seal and a valve spring replacement tools are needed for this job. Engine technicians need four specific tools for the job: valve spring compressor (J 43649), Valve Stem Oil Seal remover (J 36017), flywheel holding tool (J 43653), and sprocket holding tool (J 43655). Prevent
Crankshaft spin until applying compressed air into the cylinder space because sprocket holding tool (J 43655) can get damaged. Manual transmission automobiles require first gear position along with the activated parking brake. Automatic vehicles need their starter removed for service work. Use the flywheel holding tool (J 43653) to install it while removing the
Camshaft and Camshaft roller followers. Screw the valve spring compressor (J 43649) front section into the second Camshaft cover bolt hole while fastening its remaining components to the cylinder head. Use an air hose adapter and hose to pressurize the cylinder into 690 kpa (100 psi) while the adapter remains inserted in the
Spark Plug hole. Apply the valve spring compressor (J 43649) to compress each valve spring before removing the valve spring keepers, retainer, and spring. Install the Valve Stem Oil Seal remover (J 36017) to remove existing valve seals before installing new ones with the same tool until they reach full seat depth. Using a valve spring compressor (J 43649) compress the valve spring once again before you install the keepers. Remove the evaporator air hose adapter while disconnecting the air hose then remove the valve spring compressor (J 43649) from the cylinder head. Replace all original components by installing the spark plugs and Camshaft roller followers and Camshaft. If using the flywheel holding tool (J 43653) then remove it to install the starter before closing the cover.
