Suzuki Jimny Gen 3 Differential Breather Kit

The Jimny Gen 3 differential breather kit relocates the front and rear differential breathers to a higher position inside the engine bay. This setup helps reduce the chance of water entering the differentials when the vehicle crosses deep water.

Des Sol supplies the kit with a lightweight anodised-aluminium manifold, breather hoses, OEM-compatible couplings, fittings and installation tools. In addition, the special coupling design fits onto the existing differential breather points without drilling or tapping the housings.

Why Extend the Differential Breathers?

Differentials heat up while the vehicle is moving. However, cold water can cool them quickly during a deep crossing. The air and oil inside then contract, which can create low pressure inside the housings.

As a result, the differential may draw water through a low factory breather or worn oil seal. Water can then mix with the gear oil and reduce its ability to protect the gears and bearings.

The Suzuki Jimny differential breather kit moves the breather outlets to a cleaner and higher location in the engine bay. Therefore, the differentials can draw air from above the vehicle’s lower underbody area.

No Drilling or Tapping Required

Some breather installations require users to drill or tap the differential housings. This process can allow metal pieces to enter the oil if the installer does not clean the housing correctly.

Instead, Des Sol’s coupling design connects to the existing OEM breather locations. Consequently, the installer can fit the Jimny axle breather kit without drilling new threads into either differential housing.

Complete Breather Extension Kit

The kit includes the main parts required for installation, so owners should not need to search for extra hoses, nuts or fittings halfway through the job. The supplied components also help create a neat and consistent installation.

Before fitting the kit, check that every hose and connector is present. Also, route each hose away from the exhaust, sharp edges, moving suspension parts and rotating drivetrain parts.

Installation and Maintenance

Follow the Des Sol fitting instructions carefully or ask a trained installer to fit the kit. Secure every hose without sharp bends, and leave enough movement for the axles and suspension to travel freely.

After installation, check the hose routing and all connections. Furthermore, inspect the kit after off-road trips and during normal vehicle services. Replace any crushed, cut, loose or heat-damaged hose before the next water crossing.

Important: A differential breather extension reduces the risk of water entry, but it does not make the differentials waterproof. Always inspect the differential oil after a deep crossing. If the oil looks cloudy or milky, stop using the vehicle and have the differential serviced.
