Q: Where Is the Cylinder Head Typically Located?
A: The cylinder head seals the cylinder to create room for the combustion chamber. It also forms the housing for the valve gear and the spark plugs. As such, it can warp due to the pressure placed by the temperature changes of combustion.
The cylinder head is usually on top of the cylinder, forming the upper ceiling of the combustion chamber above each piston. The intake and exhaust duct hoses typically intersect in the cylinder head, along with other valves and springs.
Tips on How to Access the Cylinder Head
To access the cylinder head, you’ll have to remove other connected parts first, starting with the drain cap. It’s usually at the front of the engine compartment behind the grille. Unscrew the cap and the oil pan’s drain plug to release the coolant and the oil.
After that, remove the engine intake and exhaust manifolds using a ratchet or a wrench to separate them from the cylinder head. Then, detach the valve covers and the timing belt.
Remove the rocker arm (or arms if the engine uses two). Behind it, you’ll see the mounting bolts that keep the cylinder head in place.
Finally, replace the cylinder head and the mounting bolts with the new pieces.
