Q: How to replace the engine front timing cover on 2002 Chevrolet Camaro?
A: If you want to replace the engine front cover, first, run the engine oil and the coolant, followed by removal of intake air temperature (IAT) sensor electrical connector and removal of air intake duct. Loosen the coolant pump pulley bolts, take out the drive belt tensioner, and the Power Steering Pump. Lift and support the vehicle, remove crankshaft balancer, oil pressure electrical connector, crankshaft position sensor electrical connector, and the Crankshaft Position Sensor shield and studs and sensor. Loosened the Oil Pan bolts to provide clearance for the front cover installation, lowered the vehicle, and removed the coolant pump pulley bolts and the pulley itself. Remove the radiator outlet hose and carefully pry out the crankshaft front oil seal. Removal of the engine front cover studs and bolts, removal of the engine front cover and gasket respectively. When extracting the front cover, it is also necessary to remove the bolts of the coolant pump, coolant pump, coolant pump gaskets, oil filter adapter, camshaft position sensor and oil pump gear set. Clean the engine front cover and block surfaces, and if front cover was removed, install the oil pump gear set, camshaft position sensor, and oil filter adapter. Fit the coolant pump gasket to the front cover , and fit the coolant pump, using the j 36660-a torque angle meter to torque the coolant pump bolts to 15nm (11 ft lbf) and an additional 80°.
