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.

Measure the diameter of the valve guide using gauge MKM-571-B and a commercially available inside micrometer.

An oversize service code is on the valve guide and the valve stem end. The following table gives the correct size, reamer, and production code for each service.

Ream the valve guide from the upper side of the cylinder head to the next oversize.
