- Risk of damage to radiator surface
→ Clean radiator surface regularly.

→ Do not use a high-pressure steam cleaner.
Never use a high-pressure steam cleaner.
1. 2.1. High-pressure steam cleaners can cause additional particles of dirt to attach to the radiator surfaces and the engine can overheat due to reduced cooling performance.
