NOTICE: During engine repair procedures, cleanliness is extremely important. All parts must be thoroughly cleaned and any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.

NOTICE: If the oil pan was removed during engine disassembly, it must be installed after the engine and transaxle are assembled and the transaxle-to-engine bolts are installed. Failure to follow this assembly sequence can result in engine oil leaks.

NOTE: Assembly of the engine requires various inspections/measurements of the engine components (engine block, crankshaft, connecting rods, pistons and piston rings). These inspections/measurements will aid in determining if the engine components will require replacement. For additional information, refer to Engine.

81. NOTICE: 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 (303-458).

Position the coolant pump pulley over the previously installed Camshaft Pulley Installer and on the end of the camshaft. Install the Camshaft Pulley Installer, Power Steering Pump Pulley Installer and the Water Pump Pulley Spacer as shown in the illustration.
- Using the Camshaft Pulley Installer, Power Steering Pump Pulley Installer and the Water Pump Pulley Spacer, install a new service coolant pump pulley flush with the end of the camshaft.





82. Install the coolant pump belt on the coolant pump pulley and position it on the camshaft pulley.





83. NOTICE: Do not use any screwdrivers, pliers or other metal objects that could cause damage to the belt or camshaft pulley while installing the belt.

Rotate the crankshaft clockwise to seat the water pump belt on the camshaft pulley.

Install the 6 coil-on-plugs and the bolts.
- Tighten to 6 Nm (53 lb-in).





99. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

NOTE: Clean and inspect all sealing surfaces. Install new gaskets.

Position the lower intake manifold and install the 8 bolts.

- Tighten in the sequence shown to 10 Nm (89 lb-in).





100. NOTICE: Use O-ring seals that are made of special fuel-resistant material. Use of ordinary O-rings can cause the fuel system to leak. Do not reuse the O-ring seals.

- Separate the fuel injectors from the fuel rail.

- Remove and discard the fuel injector O-rings.

- Install new O-rings and lubricate with clean engine oil.

- Install the fuel injectors onto the fuel rail.





101. Install the 4 bolts and the fuel rail and injectors assembly.
- Tighten to 10 Nm (89 lb-in).





102. NOTICE: If the engine is repaired or replaced because of upper engine failure, typically including valve or piston damage, check the intake manifold for metal debris. If metal debris is found, install a new intake manifold. Failure to follow these instructions can result in engine damage.

NOTE: Clean and inspect all sealing surfaces. Install new gaskets.
