Description

Contrary to what many people believe, cylinder head replacement is not a complicated process. You can do it yourself, provided you know what is required and the steps involved. This article focuses on the procedure to follow when replacing a damaged cylinder head. To start us off, a look at why a cylinder head in a car may need to be changed.

Reasons for Cylinder Head Replacement

A cracked cylinder head can be welded, and a warped head resurfaced. Voids can also be filled with a sealing material. However, refurbished cylinder heads often do not last for long. There are also situations where cylinder head repair will not work. Such instances include:

End of lifespan- Aluminum heads last for around five years, cast iron heads a few more. Besides the type of cylinder head material, allowing the engine to overheat can cause irreparable damage.

Past resurfacing- There is a limit to the number of times you can carry out cylinder head resurfacing. Machining removes layers of metal. You cannot do it too many times.

Extreme Cracking- you can fix cracks easily by welding them. If they are too large, cylinder head replacement could be the only option available.

Excessive Warping– a badly warped head cannot be machined to create a flat surface. It can only be replaced.

Cylinder Head Replacement Procedure

You will need: a wrench set, ratchet and socket set, screwdrivers, new oil, coolant, rags, and new cylinder head.

Cylinder head Removal

Drain the Coolant and Oil

Unscrew the radiator’s drain cap to release coolant out of the system. Remove also the oil pan’s drain plug to pour out the oil.

Remove the Engine Intake and Exhaust Manifolds

Deconstruct the intake and exhaust manifolds. Use a ratchet or wrench to separate them from the cylinder head. You will also need to remove the valve covers. Again, use the ratchet and socket set to do the job. Remove also the timing belt.
