In-Vehicle Repair: Camshafts: Removal

WARNING: This page is about a different variant/trim than selected.

NOTE: During engine repair procedures, cleanliness is extremely important. 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.

NOTE: Do not rotate the camshafts unless instructed to in this procedure. Rotating the camshafts or crankshaft with timing components loosened or removed can cause serious damage to the valves and pistons.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING article.
Remove the accessory drivebelt. For additional information, refer to ACCESSORY DRIVE - 2.5L article.
Remove the Variable Camshaft Timing (VCT) oil control solenoid. For additional information, refer to ELECTRONIC ENGINE CONTROLS - 2.5L article.
Remove the front RH wheel and tire. For additional information, refer to TIRES & WHEELS article.
Check the valve clearance. For additional information, refer to VALVE CLEARANCE CHECK in this service information.

NOTE: Failure to position the No. 1 piston at Top Dead Center (TDC) can result in damage to the engine. Turn the engine in the normal direction of rotation only.

Using the crankshaft pulley bolt, turn the crankshaft clockwise to position the No. 1 piston at Top Dead Center (TDC).
- The hole in the crankshaft pulley should be in the 6 o'clock position.

NOTE: The Camshaft Alignment Plate is for camshaft alignment only. Using this tool to prevent engine rotation can result in engine damage.

NOTE: The camshaft timing slots are offset. If the Camshaft Alignment Plate cannot be installed, rotate the crankshaft one complete revolution clockwise to correctly position the camshafts.

Install the Camshaft Alignment Plate in the slots on the rear of both camshafts.
Remove the engine plug bolt.

NOTE: The Crankshaft TDC Timing Peg will contact the crankshaft and prevent it from turning past TDC . However, the crankshaft can still be rotated in the counterclockwise direction. The crankshaft must remain at the TDC position during the camshaft removal and installation.

Install the Crankshaft TDC Timing Peg.

NOTE: Only hand-tighten the bolt or damage to the front cover can occur.

Install a 6 mm x 18 mm bolt through the crankshaft pulley and thread it into the front cover.
Remove the lower front cover timing hole plug from the engine front cover.

NOTE: Releasing the ratcheting mechanism in the timing chain tensioner allows the plunger to collapse and create slack in the timing chain. Installing an M6 x 30 mm bolt into the upper front cover timing hole will hold the tensioner arm in a retracted position and allow enough slack in the timing chain for removal of the exhaust camshaft gear.

Using a small pick tool, unlock the chain tensioner ratchet through the lower front cover timing hole.
- Using the flats of the camshaft, have an assistant rotate the exhaust camshaft clockwise to collapse the timing chain tensioner plunger.
- Insert an M6 x 30 mm bolt into the upper front cover timing hole to hold the tensioner arm in the retracted position.
Using the flats on the camshaft to prevent camshaft rotation, remove the bolt and the exhaust camshaft drive gear.

NOTE: Failure to follow the camshaft loosening procedure can result in damage to the camshafts.

NOTE: Mark the location and orientation of each camshaft bearing cap.

Fig 14: Removing Sequence Of Camshaft Bearing Cap Bolts

Remove the camshafts from the engine.
- Loosen the camshaft bearing cap bolts, in sequence, one turn at a time until all tension is released from the camshaft bearing caps.
- Remove the bolts and the camshaft bearing caps.
- Remove the camshafts.
If removal of the camshaft phaser and sprocket is necessary, mark the sprocket and camshaft for reference during installation.
- If necessary, place the camshaft in a soft-jawed vise. Remove the bolt and the camshaft phaser and sprocket.
