Glow Plug Testers for Diesel Engines

Test glow plugs quickly and without removing them. Defective glow plugs can cause cold-start problems, especially in diesel engines. With a professional glow plug tester, you can check the condition of compatible glow plugs directly on the vehicle without having to remove the glow plug for testing.

The GKP 05 glow plug tester from Autotestgeräte Leitenberger is suitable for 4.4-V, 5-V, and 12-V glow plugs. Among other things, it can be used to test rod-type glow plugs, ceramic glow plugs, and glow plugs from ISS quick-start systems in passenger cars, commercial vehicles, and industrial diesel engines.

Connection to the glow plug and ground is made via robust test clamps. The test result is clearly displayed on an LED indicator as “Glow plug OK” or “Glow plug defective”. This allows the GKP 05 to perform a quick preliminary diagnosis of the preheating system without unnecessarily removing functional glow plugs.

Separate turning and extraction tools are required for the mechanical removal of seized or damaged glow plugs.
