tool, release ratchet pawl by pulling pawl back against spring force through access hole on side of tensioner. While continuing to hold pawl back,
Push ratchet device to approximately 2 mm from the tensioner body. Install Special Tool 8514 lock pin (3) into hole on front of tensioner (2).
Slowly open vise to transfer piston spring force to lock pin.

NOTE: The silver bolts retain the guides to the cylinder heads and the black bolts retain the guides to the engine block.
4. Install the left side chain guide. Tighten the bolts to 28 Nm (250 in. lbs.).
CAUTION: Overtightening the tensioner arm torx(R) bolt can cause severe damage to the cylinder head. Tighten torx(R) bolt to specified
torque only.
5. Install left side chain tensioner arm. Apply Mopar(R) Lock N, Seal to torx(R) bolt, tighten bolt to 28 Nm (250 in. lbs.).
