Hose leak test and fluid leak detection (10,000 km/12 months) (Peugeot 406)

The operation for checking the tightness of the hoses is the same as for vehicles with gasoline engines, except for the following differences.

Fuel

1. Check all high pressure fuel lines and their connections to the fuel pump and injectors.

2. Check the tightness of the fuel lines at their connections.

3. Also check the area around the fuel injectors for fuel leaks.

Hydraulic clutch

On hydraulic clutch models, check for leaks around the pipe connections to the clutch master cylinder and to the clutch slave cylinder bolted to the clutch housing.
