MG HS: Significant coolant drop over a short period
Symptoms
- The coolant level drops significantly over a short period, or a leak is suspected. [1]
Possible causes
- The manual requires an authorized repair provider to check for leaks when the level drops significantly; it does not identify a specific failed component. [1]
Checks
- Check MIN/MAX with the engine cold and the vehicle on level ground; do not open the cap when the engine is hot. [1]
What to do
- After identifying the leak, repair and address the coolant according to the vehicle's requirements. [1]
Applicability and limits
- Only applies to the English manual from the official European website and to the corresponding HS configuration among the combustion-engine configurations described; the manual date is not treated as an applicable model year. No actual vehicle model has been linked. Do not extend to models with the same name, other powertrains or other markets. Scope: unknown [1]
- Only applies to the specific configuration in the cited manual; do not assume applicability to all vehicles with the same model name
