• Q: How to Service the Timing Cover and Chain on 2005 Jeep Grand Cherokee?

  A: Before servicing the timing chain, you should remove the negative cable and get rid of the coolant. Take out the electric cooling fan and fan shroud first and then get rid of the radiator fan. Remove the heater hoses from the timing cover and also the lower radiator hose from the engine. After that, discard the accessory drive belt tensioner assembly (1), along with the damper, generator and A/C compressor. Note also that unlike other engines, the front cover on the 3.7L one is sealed with an anaerobic coating, making it necessary to use Mopar Grey Engine RTV sealant during service. It's possible to access the timing cover without having to take out the water pump. Remove the bolts connecting the timing cover to the engine block and then lift the cover from the engine block. When installing, wipe down the timing chain cover and engine block using rubbing alcohol and make sure you keep away from all products that are oil-based or abrasive to prevent accidental damage. Examine the water surging connection (2) for damage and exchange it as is required. Use the RTV sealer to cover the front cover in a layer 3 to 4mm thick, then attach the cover by tightening the fasteners in sequence to 58 Nm (43 ft. lbs.). Replace the crankshaft damper, A/C compressor, generator and accessory drive belt tensioner. Link the radiator upper and lower hoses, as well as both heater hoses and the radiator fan. At the end, put the refrigerant in the cooling system and connect the battery's negative cable.
