On the 2009-2020 Suzuki Alto 1.0 K10B, the K10B 1.0 3-cylinder in Alto, Celerio (early), Splash, and Wagon R uses shim-under-bucket valve adjustment — not the more common hydraulic lash adjusters. Suzuki specifies a check at 96,000 km but many owners (and dealers) skip it; tight valves over time cause burned exhaust valves and failed compression.

Common Symptoms

  • rough idle
  • misfire
  • low compression
  • reduced economy

How to Fix

Valve clearance check + adjustment at 96,000 km is in the service book — confirm it has been done. £200-£400 labor + shims. If skipped repeatedly, eventually a leak-down test will reveal valve burn — head rebuild £700-£1,200.

Typical repair cost:$200 - $1,200
