Water Leakage Test

WATER LEAKAGE TROUBLE DIAGNOSIS

Water Leakage Test

- Visually check for water leakage after repairing.
- If complaint or claim for water leakage come from owner although hose test goes well, shower test is needed.
NOTE:
It is considered normal if level of water flow on center pillar upper end is kept at a level that water flows along with passenger room side glass.

HOW TO CHECK BY HOSE

1.2 workers are required. One worker checks inside the vehicle, and the other one washes with water.





2.Use 13 mm (0.51 in) diameter hose (A). Adjust water pressure by following method.
Hold the hose horizontally, and release water at 1000 mm (39.37 in) height from ground. Adjust the distance, between the ground point just below the hose and the water dropping point, to reach 700 mm (27.56 in). (See the figure.)
3.Keeping the distance between the hose and the testing area by 100 mm (3.94 in), apply water along the area 3 times. During applying water, move the hose by 100 mm (3.94 in)/sec speed.
4.Visually check for water leakage.

HOW TO CHECK BY SHOWER






1.Adjust water flow as the same as hose test.
2.Shower by hose with shower head (A) keeping distance about
700 mm (27.56 in) far from vehicle.
3.Keep showering 30min against each weather-strip which might cause water leakage.
4.Visually check for water leakage.
