Question 1

How to replace the Cam Gear for Bank 2 on Chevrolet Camaro?

Accepted Answer

The replacement of bank 2 camshaft position actuator starts with removing both the Intake Manifold and the left camshaft cover. The maintenance process starts with sensor removal of the left intake and exhaust camshaft position sensors and additional removal of left intake and exhaust camshaft position actuator solenoids. You should turn the crankshaft balancer bolt to a clockwise direction so the camshafts reach their neutral position before marking the camshaft Timing Chain and position actuators for reassembly. Mark appropriate positions on the Timing Chain links and the neighboring teeth on both the intake and exhaust camshaft position actuators. With an open-end wrench during this procedure grip the camshafts to move them in unison and produce chain slack before removing the en-48313 (Timing Chain Retention Tool) so its legs can retract. Place the en-48313 tool between the front-facing camshaft actuators and adjust its legs to reach the Timing Chain until they just stop but avoid tightening down. After hand-tightening the tool you need to rotate the camshafts to generate additional slack. The brevity of the tool allows it to maintain position of the Timing Chain. An open-end wrench serves as a tool to stop engine rotation before removing the camshaft position actuator bolts so the actuators can be taken off when needed. Begin actuator installation by aligning marks from the actuator to marks on the Timing Chain which were established during removal then place the parts while keeping the bolts loose. Take the en-48313 tool off before installing the correct camshaft thrust washer according to the number of actuator attaching screws. Reapply the new actuator bolts with a torque of 58 nm (43 lb ft) when the actuator needs replacement. The last stage includes reinstallation of the left intake and exhaust camshaft position actuator solenoids along with sensors and left camshaft cover and Intake Manifold.

Question 2

How to replace the Cam Gear intake sprocket on Chevrolet Colorado?

Accepted Answer

The first task for camshaft intake sprocket replacement requires camshaft cover removal. cek the rotation of the Crankshaft in a clockwise direction for the #1 Piston to pass tdc while located on compression stroke. Position the timing mark from the intake camshaft sprocket onto the following Timing Chain link for marking. Fasten the camshaft holding tool (J 44221) at the back end of the camshafts. Securely position the Timing Chain retention tool (J 44217) along with the chain holding tool (J-44217-45) through their hooks into Timing Chain links near Timing Chain shoes both at the front and back engine sides while tightening wingnuts until the hooks remain firmly in position and gage blocks stay secure. First remove and throw away the intake camshaft sprocket bolt before you uninstall the intake camshaft sprocket. To install the new intake camshaft sprocket begin by positioning its timing mark directly with the marked link of the Timing Chain. Use a new bolt to secure the new intake camshaft sprocket onto the intake camshaft while tightening it with 20 n.m (15 lb ft) torque and 100 degrees additional angle meter (J 45059) measurement. The last step requires you to take off the camshaft holding tool (J 44221) and chain holding tool (J-44217-45) as well as the Timing Chain retention tool (J 44217) before putting back the camshaft cover.

Question 3

How to replace the Cam Gear Position Intake Actuator on Chevrolet Malibu?

Accepted Answer

Before installing the Camshaft position intake actuator the mechanic must remove the Camshaft cover along with upper Timing Chain Guide bolts and guide. A 24 mm wrench (J 44217) should be used to secure the Camshaft during bolt loosening yet the intake Camshaft actuator bolt remains intact. The Timing Chain tensioner tool (J 44217) should have its tips extended completely into the Timing Chain for replacement purposes. The Timing Chain tensioner tool (J 44217) has one tool that must be installed on the exhaust Camshaft side to hold the Timing Chain before tightening its nuts firmly. Use another tool from the Timing Chain tensioner tool (J 44217) to perform the same operation on the intake Camshaft side. Tag the positioning and location markings for intake and exhaust Camshaft actuators which are present on the Timing Chain. Extract the intake Camshaft actuator bolt and discard it afterward while removing the intake Camshaft actuator from its position on the Camshaft and Timing Chain. When installing the exhaust Camshaft actuator make sure its alignment mark matches the Timing Chain mark precisely. The Timing Chain should be fitted on the intake Camshaft actuator with proper alignment to the Timing Chain mark before installing the actuator onto the Camshaft unit. Fasten the new intake Camshaft actuator bolt until secure but continue holding the tools in place on both the intake and exhaust Camshaft Timing Chain assembly sides before removing them. After securing the Camshaft using a 24 mm wrench (J 44217) you must tightly tighten the new Camshaft actuator bolt to 85 n.m (63 lb ft) by adding another 30 degrees using the angle meter (J 45059). Install the upper Timing Chain Guide followed by its bolts while torquing them to 10 n.m (89 lb in) then replace the Camshaft cover.
