Is Foam in the Car Radiator a Normal Phenomenon?

[DiZoe]

Foam in the car radiator is not a normal phenomenon. Here are the relevant details: Reasons for bubbles in the radiator: Under normal circumstances, there should be no bubbles in the cooling system. The presence of bubbles can reduce the coolant's ability to absorb engine heat, leading to a higher likelihood of rising water temperature. Bubbles in the radiator coolant may indicate a damaged cylinder head gasket. In such cases, the solution is to immediately proceed with repair and replacement. Regularly replace the coolant: The coolant in the car radiator circulates for extended periods, and it is inevitable for various impurities to accumulate, affecting the cooling efficiency. Therefore, it is essential to replace the coolant regularly according to the intervals specified in the vehicle's manual.
