Seal, coolant tube - 509145 VALEO

A car engine will work flawlessly if all its parts are lubricated thoroughly with high-quality oil. For this, motorists periodically replace the substance in the crankcase. To avoid the spread of oil to other parts and assemblies, all connecting elements are sealed with special seals and rings.

The conditions of the seal usage

After some time, the O-rings cease to perform their function and need to be replaced with new consumables. When the system is depressurized, the oil will begin to "leave", a significant expense item will be added due to the need for constant topping up of lubricants. In addition to additional spending on oil, there is a high probability of particles of seals entering the engine. This is already fraught with failure of the motor.

If we talk about oil seals, then we should talk about their design. The rubber tip is reinforced with a steel sleeve with a spring, which ensures a snug fit of the lip of the VALEO brand Seal, coolant tube against the working surface of the valve. The rubber-sealing ring, being in an aggressive oil environment and under constant exposure to high temperatures, quickly deteriorates. It is very important to monitor its condition and change it in time
