Coolant Pump: Installation
-
NOTE: Clean and inspect all sealing surfaces.
Install new gaskets.
- Install the coolant pump and the bolts.
Torque: Stage 1: 89 lb.in (10 Nm) Stage 2: 45°
- Remove all of the shop towels from the oil pan opening.
-
NOTE: Any coolant that has accumulated in the oil pan must be drained from the pan and any residual coolant cleaned from the front of the engine and oil pan. Failure to remove all traces of the coolant can result in oil contamination and severe engine damage.NOTE: Remove any residual coolant from the front of the engine and the oil pan using regulated, compressed air and clean, lint-free shop towels.
Remove the oil pan drain plug and allow any accumulated coolant to drain.
- Install the oil pan drain plug.
Torque: 20 lb.ft (27 Nm)
- Install the RH primary timing chain guide and the bolt.
Torque: 89 lb.in (10 Nm)
- Compress the RH secondary timing chain tensioner and install the Secondary Chain Hold Down in the hole on the rear of the secondary timing chain tensioner guide and let it hold against the mega cap to retain the tensioner in the collapsed position. Install Special Service Tool: 303-1530 Tool, Chain Tensioner Hold Down.
- Align the colored links with the timing marks. Assemble the RH VCT assembly, the RH exhaust camshaft sprocket and the RH secondary timing chain.
-
NOTE: It may be necessary to rotate the camshafts slightly, to install the RH secondary timing assembly.
Position the 2 RH VCT assemblies and secondary timing chain onto the camshafts by aligning the holes in the VCT assemblies with the dowel pins in the camshafts.
- Install the RH VCT bolts
Torque: Stage 1: 30 lb.ft (40 Nm) Stage 2: Loosen: 1 turn(s) Stage 3: 18 lb.ft (25 Nm) Stage 4: 180°
-
NOTE: Make sure the secondary timing chain is centered on the timing chain tensioner guides.
Compress the RH secondary timing chain tensioner and remove the Secondary Chain Hold Down. Remove Special Service Tool: 303-1530 Tool, Chain Tensioner Hold Down.
- Install the upper LH primary timing chain guide and the bolt.
Torque: 89 lb.in (10 Nm)
-
NOTE: It may be necessary to rotate the camshafts slightly, to align the timing marks.
Install the primary timing chain with the colored links aligned with the timing marks on the VCT assemblies and the crankshaft sprocket.
- Install the lower LH primary timing chain guide and the bolts.
Torque: 89 lb.in (10 Nm)
- Install the primary timing chain tensioner arm.
-
- Release the ratchet detent.
- Using a soft-jawed vise, compress the ratchet plunger.
- Align the hole in the ratchet plunger with the hole in the tensioner housing.
- Install a lockpin.
-
NOTE: It may be necessary to rotate the camshafts slightly to remove slack from the timing chain to install the tensioner.
- Install the primary tensioner and the bolts.
Torque: 89 lb.in (10 Nm)
- Remove the lockpin.
- Install the primary tensioner and the bolts.
-
- As a post-check, verify correct alignment of all timing marks.
- There are 48 links in between the RH intake VVT assembly colored link (1) and the LH intake VVT assembly colored link (2).
- There are 35 links in between LH intake VVT assembly colored link (2) and the 2 crankshaft sprocket links (3).
-
NOTE: Do not use excessive force when installing the VVT oil control solenoid. Damage to the mega cap could cause the cylinder head to be inoperable. If difficult to install the VVT oil control solenoid, inspect the bore and VVT oil control solenoid to ensure there are no burrs, sharp edges or contaminants present on the mating surface. Only clean the external surfaces as necessary.
Install the LH intake VCT oil control solenoid and the bolt.
Torque: Stage 1: 71 lb.in (8 Nm) Stage 2: 20°
