The water leakage inside the lower side of the new Alto front cover cable is caused by the blockage of the drainage system and the water leakage of the engine cooling system.

1. Drainage system blockage: Usually, a drainage system is designed on the front cover of the vehicle to eliminate stagnant water. If the drain hole is blocked, water will accumulate and seep into the cover. Find and clean the drain hole to ensure that the drain hole is not blocked or blocked.

2. Leakage of engine cooling system: Sometimes, the engine cooling system may leak, causing the coolant to penetrate into the front cover. Check the connecting pipes, coolant containers and coolers of the engine cooling system for any signs of leakage, and repair or replace the corresponding components.
