Replacing a camshaft is indeed a simple task for anyone. But the process includes many associated specs to cost you time. And final alignment must stand precise regarding operational safety.

You should know the setup process, in brief, to keep yourself occupied. Otherwise, leave the job for professionals requiring 16 – 24 hours of service time.

#1. Check the user manual to determine the camshaft specs. Park your vehicle on a spacious level surface.

#2. Open the engine hood, allowing the machine to cool. Stabilize the rear wheels using wheel chocks.

#3. Jack up the vehicle’s front using a suitable jack stand. Put the jack stand right under the welded body pinch.

#4. Look into the manual to locate different assembly parts. Start removing the drive belt using a belt tensioner.

#5. Determine whether you need to remove the engine. Pay attention to remove the timing cover for access.

#6. Clear the crankshaft snout to lower the oil pan. Unscrew the bolts right before disconnecting the battery.

#7. Disconnect the ignition coil wires to remove the part. Use a suitable ratchet & socket to pass the step.

#8. Remove the valve cover to access the internal parts. You get to access the rockers, pushrods & lifter set.

#9. The valve cover may get stuck in the assembly. Gently use a pry bar in the proper way to loosen the joint.

#10. Take out the connectivity in a plausible order. Keep all the removed parts assembled in the same order.

#11. Rotate the camshaft to locate the TDC (Top Dead Center). It concerns a V-shaped timing mark on the top.

#12. Loosen the timing belt tensioner to take out the belt from its gear. Keep the crankshaft steady from rotating.

#13. Remove the retainer bolts to hold the cam bearing cap. Loosen the cap in an even order with a gentle press.

#14. Grab to pull the old camshaft straight upward. Confirm a steady holding to avoid accidental falls on bearings.

#15. Loosen the central bolt to remove the camshaft gear. Wipe the empty camshaft slot using a clean cloth.

#16. Start installing the new camshaft gear with the central bolt. Set the camshaft bolt to impose necessary torque.

#17. Place the replacement cam into an aligned position. Gently put it on the cylinder head without banging the walls.

#18. Continue restoring the disassembled parts. Maintain the same manner in reverse, looking into the order.

#19. Strictly maintain the proper alignment of the individual part. Take your time to reinstall all the previous connections.

#20. Tighten the bolts using your bare hands at the first attempt. Don’t overtighten the placed bolts using tools.

#21. Start the engine to check the alignment before completion. Closely look into the actual engine response.

#22. Rotate the engine to several revolutions with a ratchet. Confirm the timing mark alignment with the engine.

#23. Lower your vehicle from the jack to the ground. Make a test drive to judge the improvement on initial action.
