Professional engine builder installation required. Proper procedure is critical for engine reliability:

1. Prepare the engine block – Thoroughly clean the block and inspect for cracks or damage
2. Remove old liners – Use a proper liner puller to remove worn liners
3. Clean liner bores – Remove all debris, old sealant, and rust from block liner counterbores
4. Measure new liners – Verify dimensions against OEM specifications
5. Check liner protrusion – Install liners without seals to measure protrusion above the deck; shim if necessary
6. Install liner seals – Install new O-ring seals on the liner lower section (if applicable)
7. Apply sealant – Apply approved sealant to the liner seating surface if specified
8. Press-fit the liner – Use a proper press and mandrel to install the liner into the block
9. Check protrusion again – Measure final liner height above the block deck
10. Hone if necessary – Perform final plateau honing to achieve the correct finish for ring seating
11. Install new pistons and rings – Use new rings and ensure proper ring gap orientation
12. Clean thoroughly – Wash the block and bores to remove all installation debris
13. Check rotating assembly – Ensure crankshaft and connecting rods rotate freely with new liners
