Coolant Pump: Installation
- Install a new gasket, the coolant pump and the 8 bolts. Tighten in the sequence shown in illustration in 2 stages:
- Stage 1: Tighten to 10 Nm (89 lb-in).
- Stage 2: Tighten an additional 45 degrees.
- Remove all of the shop towels from the oil pan opening.
- Remove the oil pan drain plug and allow any accumulated coolant to drain.
- Remove any residual coolant from the front of the engine and the oil pan using regulated, compressed air and clean, lint-free shop towels.
- Install the oil pan drain plug and tighten to 27 Nm (20 lb-ft).
- Install the RH primary timing chain guide and the bolt.
- Tighten to 10 Nm (89 lb-in).
- Assemble the LH VCT assembly, the LH exhaust camshaft sprocket and the LH secondary timing chain.
- Align the colored links with the timing marks.
- Position the LH secondary timing assembly onto the camshafts.
- Install the new VCT bolt and new exhaust camshaft bolt and the original washer. Tighten in 4 stages.
- Stage 1: Tighten to 40 Nm (30 lb-ft).
- Stage 2: Loosen one full turn.
- Stage 3: Tighten to 10 Nm (89 lb-in).
- Stage 4: Tighten 90 degrees.
- Remove the lockpin from the LH secondary timing chain tensioner.
- Install the upper LH primary timing chain guide and the bolt.
- Tighten to 10 Nm (89 lb-in).
- 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 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Install the primary timing chain tensioner arm.
- Reset the primary timing chain tensioner.
- 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 and install a suitable lockpin.
- Install the primary tensioner and the 2 bolts.
- Tighten to 10 Nm (89 lb-in).
- Remove the lockpin.
- As a post-check, verify correct alignment of all timing marks.
- There are 48 links between the RH intake VCT assembly colored link (1) and the LH intake VCT assembly colored link (2).
- There are 35 links between the LH intake VCT assembly colored link (2) and the 2 crankshaft sprockets colored links (3).
- Inspect the VCT housing seals for damage and replace if necessary.
- Inspect the VCT housing-to-cylinder head O-ring seals for damage and replace as necessary.
- Install the LH VCT housing and the 3 bolts.
- Tighten in the sequence shown in illustration to 10 Nm (89 lb-in).
- Install the RH VCT housing and the 3 bolts.
- Tighten in the sequence shown in illustration to 10 Nm (89 lb-in).
- Install a new engine oil filter.
- Tighten to 5 Nm (44 lb-in) and then rotate an additional 180 degrees.
- Install the engine front cover. For additional information, refer to ENGINE - 3.5L or ENGINE - 3.5L GTDI .
- Fill and bleed the cooling system. For additional information, refer to COOLING SYSTEM DRAINING, FILLING AND BLEEDING .
NOTE:
Clean and inspect all sealing surfaces.
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:
The crankshaft sprocket timing mark should be between the 2 colored links.

NOTE:
It may be necessary to rotate the crankshaft slightly to remove slack from the timing chain and install the tensioner.
NOTE:
RH shown in illustration, LH similar.
NOTE:
During removal, the O-ring seal may remain on the cylinder head. If so, remove the O-ring seal from the cylinder head, inspect the seal (replace as necessary) and install the O-ring seal on the VCT housing.
NOTE:
Make sure the dowels on the VCT housing are fully engaged in the cylinder head prior to tightening the bolts.
NOTE:
Make sure the dowels on the VCT housing are fully engaged in the cylinder head prior to tightening the bolts.
NOTE:
Lubricate the engine oil filter gasket with clean engine oil prior to installing the oil filter. For 3.5L engines, use 5W-20 oil. For 3.5L Gasoline Turbocharged Direct Injection (GTDI) engines, use 5W-30 oil.
