Product information

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.
