Q6: Why do CAT 320D radiators frequently experience tube bursting or side tank rupture?
A6: CAT 320D radiators often suffer tube bursting or side tank rupture due to excessive cooling system pressure, poor coolant maintenance, clogged cores, or weakened aluminum fatigue under long-term high-temperature and high-vibration operating conditions, especially when non-OEM or low-quality caps and components are used.
Q7: Can engine radiators be directly rinsed with a high-pressure water gun?
A7: It is not recommended to use a high-pressure water gun for engine radiator cleaning, as excessive pressure can damage the radiator core, bend fins, and lead to cooling efficiency loss or tube leakage.
