Mechanical Inspection: Compression
WARNING: This page is about a different car, the 2002 Suzuki XL-7, 2002 Suzuki Vitara, 2002 Suzuki Grand Vitara, 2002 Suzuki Esteem, and 2002 Suzuki Aerio. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
DO NOT use ignition switch during compression tests on fuel injected vehicles. Use a remote starter to crank engine. Fuel injectors on many models are triggered by ignition switch during cranking mode, which can create a fire hazard or contaminate the engine's oiling system.
Check engine mechanical condition using a compression gauge, vacuum gauge or an engine analyzer. See engine analyzer manual for specific instructions. Ensure engine is at normal operating temperature. Engine cranking speed must be at least 250 RPM during compression test.
