Why Is My Haval Jolion Losing Coolant Without Visible Leaks?

Some Haval Jolion owners have reported a gradual decrease in coolant levels without any visible leaks. This issue may stem from:

Heater Core Leaks: A malfunctioning heater core can cause coolant to leak into the cabin, often unnoticed.

Internal Engine Leaks: Cracks in the engine block o r cylinder head can lead to coolant entering the combustion chamber.

Radiator Cap Failure: A faulty radiator cap can cause pressure loss, leading to coolant loss.

Recommendation: Have the vehicle inspected by a qualified mechanic to identify and address the source of the coolant loss.
