The working principle is that through these connection points, the coolant circulates inside the engine, takes away heat and dissipates heat through the radiator, so as to maintain the normal working temperature of the engine
Replacement time :
It is usually recommended to consider replacing the water pipe connector after about 100,000 kilometers, because long-term high temperature and high pressure action may cause the connector loosen or damage.
In addition to the driving mileage, it is also necessary to determine whether the water pipe joint needs to be replaced according to the actual use of the joint. If the joint is found to be loose, leaking or damaged, it should be replaced immediately , even if it has not reached 100,000 km
