Questionwith 2.7L engine. I am in the midst of replacing a water pump in this vehicle. It is fully loaded. I have everything tore down and out of the way and am inside the timing chain cover. Question is, how do I get the chain loose to change the water pump out? I see no tensioner within plain view.
AnswerREMOVAL - TIMING CHAIN
Remove upper intake manifold. (Refer to 9 - ENGINE/MANIFOLDS/INTAKE MANIFOLD - REMOVAL)
Remove cylinder head covers, crankshaft vibration damper, and timing chain cover. (Refer to 9 - ENGINE/CYLINDER HEAD/CYLINDER HEAD COVER(S) - REMOVAL) (Refer to 9 - ENGINE/ENGINE BLOCK/VIBRATION DAMPER - REMOVAL) (Refer to 9 - ENGINE/VALVE TIMING/TIMING BELT / CHAIN COVER(S) - REMOVAL)
CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage.
Align crankshaft sprocket timing mark to mark on oil pump housing (TIMING MARK ALIGNMENT). The mark on oil pump housing is 60° ATDC of #1 cylinder.
CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage.
Remove primary timing chain tensioner from right cylinder head (PRIMARY TIMING CHAIN TENSIONER).
Remove camshaft position sensor from left cylinder head (TIMING DRIVE SYSTEM - PRIMARY).
Remove chain guide access plug from left cylinder head (TIMING DRIVE SYSTEM - PRIMARY).
NOTE: When camshaft sprocket bolts are removed, the camshafts will rotate in a clockwise direction.
Starting with the right camshaft sprocket, remove the sprocket attaching bolts. Remove camshaft damper (if equipped) and sprocket (TIMING DRIVE SYSTEM - PRIMARY).
Remove left side camshaft sprocket attaching bolts and remove sprocket (TIMING DRIVE SYSTEM - PRIMARY).
Remove lower chain guide and tensioner arm (TIMING DRIVE SYSTEM - PRIMARY).
Remove the primary timing chain.
For removal of crankshaft sprocket, (Refer to 9 - ENGINE/VALVE TIMING/TIMING CHAIN AND SPROCKETS - REMOV
