The Land Rover sub-bottle hose is an important part of the cooling system and is primarily used to connect the cooling system to the engine and ensure that coolant circulates through the system. Often referred to as an expansion tank, the sub-tank serves to store excess coolant and provide extra capacity when the coolant temperature rises, preventing the system from being over pressurized.

There are two main configurations of sub-jugs (expansion jugs)
High Pressure Expansion Jug
This type of sub-jug is directly connected to the cooling system and its scale can directly reflect the total amount of coolant.
Normal Pressure Expansion Pot
This type of secondary water pot does not necessarily represent the amount of coolant remaining in the cooling system, so when there is a shortage of coolant, the safest course of action is to check the amount of coolant remaining in the cooling system first, and then replenish the coolant in the expansion pot.
Common Problems and Maintenance Recommendations
During use, the secondary kettle hose may leak and overheat. To ensure that it works properly, it is recommended that the coolant balance in the cooling system be checked regularly and replenished when necessary. In addition, choosing high-quality plumbing materials and fittings is key to ensuring cooling system performance.
