## Summary description

Handheld compression tester GEKO G02504 for petrol (gasoline) engines designed to measure cylinder compression pressure. The tool connects to the spark plug hole to read peak pressure values, helping diagnose worn rings, valves, head gasket leaks and engine sealing issues. Suitable for workshop and field use by mechanics and car enthusiasts.

## Long description

Handheld compression tester GEKO G02504 for petrol engines is a compact diagnostic tool designed to measure cylinder compression pressure directly via the spark plug hole. The device records peak pressure values to help identify issues such as worn piston rings, leaking valves, head gasket failures and general sealing problems in gasoline engines. Its design suits both workshop environments and field use by mechanics and vehicle owners requiring quick, accurate pressure checks without complex setup.
Advantages
The GEKO compression tester provides direct, immediate readings of maximum cylinder pressure, enabling fast comparison between cylinders for reliable fault localization. Its handheld format and robust connector make it convenient for repeated measurements under workshop or roadside conditions. The tester’s pressure range and easy connection to the spark plug hole allow straightforward use on a wide range of petrol engines, reducing diagnostic time and supporting maintenance decisions.
Suitable for
Routine compression checks during engine maintenance
Diagnosing loss of compression due to rings, valves or head gasket
Comparative testing between cylinders to locate faults
Field checks by mechanics and car enthusiasts
Key specifications
Application: petrol (gasoline) engines
Connection method: fits into spark plug hole
Measurement type: peak (maximum) cylinder pressure
Form factor: handheld, portable diagnostic tool
Intended use: workshop and field diagnostics
How to use
Ensure the engine is at operating temperature and switch off ignition and fuel supply before testing. Remove the spark plug from the cylinder to be tested and screw in the compression tester’s adapter until secure. Crank the engine several revolutions with the throttle open while observing the tester to record the peak pressure. Repeat the procedure for each cylinder and compare values to detect discrepancies indicating wear or leaks. Follow vehicle manufacturer safety instructions and isolate ignition systems before starting the cranking procedure.
Usage recommendations
For reliable diagnostics, perform tests on a warm engine, maintain consistent cranking duration and throttle position across cylinders, and compare measured pressures against the engine’s service specifications. If readings are low or vary significantly between cylinders, consider additional tests such as a wet compression test or leak-down test to pinpoint the cause.
