2001 Chevrolet Metro Timing Belt Tensioner Parts and Q&A

• Q: How to service and repair the timing belt tensioner on 2001 Chevrolet Metro?

  A: Service operations for the Timing Belt tensioner start with similar steps involving Crankshaft timing pulley removal together with a complete air cleaner disassembly. You must start by removing the Timing Belt cover through its eight bolts and one nut before taking out the cover. Ariston professional sequence demands that you align both timing marks (1, 2) on the Crankshaft before taking away the Timing Belt. Use your finger to fully elevate the tensioner plate before you disengage the Timing Belt from both the Crankshaft and camshaft Timing Belt pulleys. You should first loosen the belt tensioner's bolt and stud. After removing the Timing Belt it is essential to refrain from turning the camshaft or Crankshaft separately in order to protect the components from damage. Remove the tensioner mechanism together with the plate, spring, and damper while inspecting both the belt and tensioner for replacement criteria. Check their smooth functioning. Install the tensioner plate to the Timing Belt tensioner by placing its lug into the hole of the tensioner. Securing the Timing Belt tensioner and tensioner plate to the cylinder block should be done through one bolt and one stud without complete tightening. The plate must follow the tensioner in motion while checking mark alignment between the camshaft Timing Belt pulley v mark on Timing Belt cover and punch mark on Crankshaft Timing Belt pulley pointing to the arrow on oil pump case. To install the Timing Belt position the arrow mark so it matches the moving direction of the Crankshaft before making sure all timing points align. Set the tensioner plate into position before applying the tensioner spring without Timing Belt slack and tightening its stud manually. The procedure for tensioning the Timing Belt requires rotating the Crankshaft two turns clockwise followed by torquing the tensioner stud to 11 nm (97 inch lbs) and the tensioner bolt to 25 nm (18 ft. Lbs.). The correct alignment of both sets of timing marks must be confirmed along with inspecting the coolant pump-to-oil case seals. Reinstall the Timing Belt cover by inserting eight bolts with one nut then tightening all to 11 nm (97 inch lbs.). Replug the Crankshaft pulley along with the air cleaner assembly.
