Replacement of the Gas Distribution Mechanism (GDM) Kit — Saving on Engine Repair
In modern foreign cars, engines operate using GDM. Its main function is to synchronize the work of the camshaft and crankshaft. The quality of fuel supply and uninterrupted engine operation depend on these mechanisms. A belt rupture leads to breakdowns and emergency major engine repairs. To avoid this, a full replacement of the GDM kit should be carried out periodically.

When should the GDM kit be replaced?
It is necessary to update the GDM belts and rollers after every 60,000 km of mileage. This figure may vary depending on the make of the vehicle; more specific data is provided in the vehicle's technical specifications. Additionally, the GDM belt needs to be replaced in case of:
- ● visible wear (cracks, tears, smoothing of scars);
- ● jamming of rollers or pump defects;
- ● "sagging" of the belt;
- ● unusual engine sounds and interruptions in operation.
When installing a new belt, it is recommended to also replace the water pump and the mechanism's rollers simultaneously. The service life of these parts is equal to that of the belt, but damage to them is often not noticeable. Replacing the entire kit at once can help the car owner save significantly.
How is the GDM belt replacement carried out? VIDEO
You can watch several recommendations for GDM replacement in the video.
The reliability and integrity of the gas distribution mechanism belt are especially important in engines where the pistons and valves are in the same block, separated only by the belt. If it breaks, the piston hits the valve, bending it. As a result — major engine repair. The process of replacing the GDM belt does not take much time.

Malfunction of any of these mechanisms immediately leads to the "jamming" of the belt and its instant rupture. That is why our service station mechanics recommend conducting a scheduled engine and GDM diagnostics once a year. This will help identify issues in time and address them.
