Expansion Tank / Non-AC
The Expansion Tank / Non-AC stores excess coolant from the radiator as the engine heats up and returns it back into the system as temperatures drop, maintaining consistent coolant levels. Its high-strength, heat-resistant construction prevents cracking, deformation, and leakage, ensuring reliable operation across varying temperature ranges.
Engineered for efficient coolant management, it helps prevent overheating, reduces pressure fluctuations, and contributes to long-term engine health and performance.
