Cylinder liners sleeves

A cylinder liner (also called a cylinder sleeve) provides a smooth and durable surface for the piston to move up and down on. They play an important role in maintaining the integrity of the engine by providing proper lubrication between the piston and the cylinder wall. This minimises wear and prevents leakage of oil and combustion gases. During the combustion cycle, a lot of heat is generated (up to 2,000C). Cylinder liners help to dissipate this heat away from the piston and into the surroundings. This contributes to optimal engine performance and prevents overheating.

Replacing cylinder liners is a specialised task that should be carried out by an experienced mechanic. However, if you wish to attempt this yourself, here is a short guide to help you.

Replacing cylinder liners

Removal: Remove the cylinder block and dismantle the piston and cylinder liner.
Inspection: Check the old cylinder liner for wear, damage, or corrosion.
Replacement: Fit a new cylinder liner of the same size and specifications.
Honing: The cylinder surface must be honed to achieve the correct roughness for optimal lubrication.
Assembly: Secure the new cylinder liner and reassemble the piston.

Remember that specific instructions may vary depending on the make and model of your car.
