Removal
1. Remove the timing drive components.
2. Cut and discard the coolant pump belt.
3. CAUTION: Failure to use the correct special tools, assembled as shown in the illustration, will result in damage to the coolant pump pulley and/or special tools.
Using the special tools, remove the coolant pump pulley.
4. NOTE: To make sure of correct sealing, do not scratch the camshaft.
Using the special tools, remove and discard the camshaft oil seal.
5. Remove the 2 bolts and the camshaft oil seal retainer.
^ Discard the press-in-place gasket.
6. CAUTION: The camshafts must be in the neutral position before removing the bearing caps or damage to the engine may occur.
Verify the camshafts are in the neutral position.
7. CAUTION: Do not allow the camshaft to rotate from the neutral position while removing the variable camshaft timing (VCT) actuator or damage to the engine may occur.
NOTE: Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for removal of the variable camshaft timing (VCT) actuator bolt.
Remove the bolt and the VCT actuator.
8. CAUTION: Cylinder head camshaft bearing caps must be assembled in their original positions. Some engines have factory markings on the camshaft bearing caps (as shown in illustration). Engines that do not have the factory markings must be marked for correct position and orientation prior to removal. Failure to install the camshaft bearing caps in their original position may result in severe engine damage.
If necessary, mark the camshaft bearing cap position and orientation as shown in the illustration.
9. CAUTION: After loosening all of the camshaft bearing cap bolts, remove the camshaft bearing thrust caps (1L and 6L) first or damage to the thrust caps may occur.
NOTE: Make sure the camshaft bearing caps are marked as instructed in the previous step.
Loosen the bolts evenly in the sequence shown.
1 Remove the camshaft bearing thrust caps (1L and 6L).
2 Remove the remaining camshaft bearing caps.
3 Remove the camshafts from the cylinder head.
Installation
1. Position the VCT actuator onto the intake camshaft.
^ Install the bolt finger-tight.
2. CAUTION: The camshafts must be installed in the neutral position or damage to the engine may occur.
Lubricate the camshafts with clean engine oil and carefully position the camshafts into the cylinder head.
^ Align the camshafts in the neutral position as shown.
3. CAUTION: The camshaft caps must be installed in their original positions or damage to the engine may occur.
CAUTION: Do not install the camshaft bearing thrust caps until all of the camshaft bearing caps have been installed or damage to the thrust caps may occur.
NOTE: Lubricate the bearing surfaces of the camshaft bearing caps with clean engine oil.
Install the camshaft bearing caps.
^ Loosely install the bolts.
4. NOTE: Lubricate the bearing surfaces of the camshaft bearing thrust caps with clean engine oil.
Install the camshaft bearing thrust caps.
^ Loosely install the bolts.
5. Tighten the camshaft bearing cap bolts in the sequence shown to 10 Nm (89 lb-inch).
6. CAUTION: Do not allow the camshaft to rotate from the neutral position while tightening the variable camshaft timing (VCT) actuator bolt or damage to the engine may occur.
NOTE: Install a 3/8-in ratchet and extension into the D-slot on the rear of the intake camshaft to hold the camshaft in place for tightening of the VCT actuator bolt.
Tighten the VCT actuator bolt to 40 Nm (30 lb-ft) plus an additional 90 degrees.
7. NOTE: Clean the sealing surface with metal surface prep before installing a new press-in-place gasket.
Install the camshaft oil seal retainer and the 2 bolts.
^ Tighten to 10 Nm (89 lb-inch).
8. NOTE: Apply clean engine oil to the seal lip and seal bore before installing the seal.
Using the special tools, install a new camshaft oil seal.
9. CAUTION: Failure to use the correct special tools, assembled as shown in the illustration, will result in damage to the coolant pump pulley and/or special tools.
Install the special tool in the camshaft as shown in the illustration.
^ Adjust the collar on the special tool screw to get the best thread engagement in the rear of the camshaft.
10. CAUTION: Failure to use the correct special tools, assembled as shown in the illustration, will result in damage to the coolant pump pulley and/or special tools.
NOTE: Only the roller collared nut from the Power Steering Pump Pulley Installer (211-185) is used on Camshaft Pulley Installer (303-485).
Position the coolant pump pulley over the previously installed special tool and on the end of the camshaft. Install the special tools as shown in the illustration.
^ Using the special tools, install a new service coolant pump pulley flush with the end of the camshaft.
11. Install the timing drive components.
12. Install the coolant pump belt.
