• Q: How to replace the timing chain tensioner on 2010 Chevrolet HHR?

  A: Dissect the negative Battery Cable to replace the Timing Chain Tensioner. Subsequently, pull out the camshaft cover and the Timing Chain Tensioner and take off the seal from the tensioner. Inspect the Timing Chain Tensioner; if the tensionor (wiska O-ring seal) or washer is damaged, change to the necessary requirements. Measure the Timing Chain Tensioner assembly from end to end. A new tensioner should be in compressed inactive state which would measure 72mm (2.83inh) from end to end; and an active state tensioner would measure 85mm (3.35inh). If the tensioner is not in the compressed position, pull the Piston assembly out of the tensioner body and put the end of the notch of the Piston assembly in the j 45027-2 and place this j 45027-2 in a vise. Mount the j 45027-1 to the ratchet cylinder, this will help in transforming the ratchet cylinder into Piston. Check bore of tensioner body for dirt & debris and, guts assume no visible bore damage; remove any contaminants using a lint-free cloth, and replace the tensioner should there be a problem. Replace the compressed Piston assembly in the bore of Timing Chain Tensioner body until it is stopped at the underside of the bore without squashing it against the bottom and measuring about 72mm (2.83 in ), straight from end to end. Clean every dirt and debris from the Timing Chain Tensioner threaded hole in the Cylinder Head. Mount the Timing Chain Tensioner assembly and tighten to 75 nm (55 lb.ft). Use a suitable tool with a rubber tip to compress and give a sharp jolt diagonally down to release the locking mechanism of the Timing Chain Tensioner, which should compress by 2 mm (0.079 in). Lastly, install the camshaft cover and connect the negative cable of the battery.
