Removing the old timing belt

You’ve figured out it’s time to replace your timing belt. And you have found the exact tools for timing belt replacement. What comes next is the procedure. If you’re a car enthusiast, you would probably do it by yourself. But if you have moderate knowledge on doing this, you would be tackling with this challenge. Usually, it would take eight hours for an untrained professional to do the whole procedure.

So, let’s start by removing the old timing belt. But do remember to first refer to your manual for proper procedures. Car models vary from the tools and the procedure of timing belt removal. But in general, you should:

·         Engage the emergency brake.
·         The car should be jacked up with jack stands.
·         The negative terminal of the battery should be disconnected for safety purposes.
·         The transmission should be placed to neutral.
·         Don’t forget to remove all spark plugs.
·         All plastic shields underneath the engine should also be removed.
·         Drain coolant.
·         All cooling fan and its covering on the engine’s front should be detached. This is usually done by turning right to loosen.
·         For easy reassembly, cooling hoses disconnected should be labelled.
·          Remove radiator, engine drive belts, cap and rotor, water pump pulley, and the bolts holding the upper timing belt cover.
·          On the center of the crankshaft pulley, place the socket. Rotate engine to TDC (Top Dead Center). This means the first piston in an inline engine is already at the top. A mark will show the TDC on the pulley and engine.
·         The crankshaft pulley bolts should be loosened to remove the pulley and vibration damper.
·         Take off the lower timing belt cover.
·         Remember to mark the location of the main tensioner bolt.
·         Now, remove the bolt which holds the tensioner and timing belt cover and the main adjustment bolt for tensioner.
·         The freed tensioner and tensioner spring should be removed next.
·         Once all these are done, the belt comes off.

At this point, removing the old timing belt is complete. We’ll discuss the next part on the next article. J
