WARNING: This page is about a different car, the 2005 Suzuki Reno and 2005 Suzuki Forenza. However, it is still accessible from the selected car via links, so may be relevant.
- Clean the sealing surfaces.
- Inspect the cylinder head gasket and mating surfaces for leaks, corrosion, and blowby.
- Inspect the cylinder head for cracks.
- Inspect the length and the width of the cylinder head using a feeler gauge and a straight edge.
- Check the sealing surfaces for deformation and warpage. The cylinder head sealing surfaces must be flat within 0.025 mm (0.001 inch) maximum.
- Measure the height of the cylinder head from sealing surface to sealing surface. The cylinder head height should be 133.975 to 134.025 mm (5.274 to 5.276 inches). If the cylinder head height is less than 133.9 mm (5.271 inches), replace the cylinder head.
- Inspect all threaded holes for damage.
- Inspect valve seats for excessive wear and burned spots.
