Cylinder head Removal

Detach the Rocker Arm

Next, remove the rocker arm. If the engine uses two heads, take out the two rocker arms.

Take off the Old Cylinder Head

Remove the mounting bolts following the correct cylinder head bolt removal sequence. The information about the sequence can be found in the car’s manual.

Next, lift off the old head from the engine housing. You may use a screwdriver to pry it loose at the edges.

Install the New Cylinder Head

Mount the new head and replace the mounting bolts. Follow the manufacturer’s specifications for both sequence and the bolt torquing.

Replace the Components

Install the other parts following the order you used to remove them: rocker arm, timing belt, valve covers, and intake and exhaust manifolds.

Refill Coolant and Oil

Finally, replace coolant using a 1:1 ratio for water and antifreeze. Refill the oil pan with oil that your car’s manufacturer recommends.

Head Gasket Replacement
Before installing the new head, check the head gasket, if it is blown. You may need to replace it also. Blown head gasket symptoms include:

Engine overheating too quickly

1. Air bubbling in the radiator even after bleeding it
2. Excess pressure in the coolant system and the radiator blowing out coolant
3. White smoke coming out of the exhaust
4. Coolant mixing with engine oil
5. Replacing a head gasket is not as intensive a process’s as repairing it. To change the gasket, follow the cylinder head replacement procedure up to the point where you have access to the gasket. Then, unmount it and put in a new one.

Question: how long does it take to replace a cylinder?

Answer: it depends on whether you are doing it yourself or have taken the car to a cylinder head repair shop. As a DIY project, cylinder head replacement time can be several hours.
