Cylinder Head Inspection - Suzuki GRAND VITARA 2005 Service Manual

Cylinder Head Inspection

• Remove all carbon deposits from combustion
chambers.
NOTE
Do not use any sharp-edged tool to scrape
off carbon deposits. Be careful not to scuff or
nick metal surfaces when decarbonizing. The
same applies to valves and valve seats, too.
• Check cylinder head for cracks on intake and exhaust
ports, combustion chambers, and head surface. Using
a straightedge and thickness gauge, check flatness of
gasketed surface at a total of 6 locations. If distortion
limit is exceeded, replace cylinder head.
Leakage of combustion gases from this gasketed joint
is often due to warped gasketed surface: such
leakage results in reduced power output.
Distortion for cylinder head surface on piston side
Limit: 0.05 mm (0.0020 in.)
