Volvo Penta VCS Yellow Ready To Use Coolant, 5 Litres, Part Number 22567314

Volvo Penta Coolant VCS (yellow) contains new inhibitors that are adapted to the materials used in modern engines. VCS (yellow) offers improved protection against corrosion and the build-up of deposits. It helps counteracts cavitations and galvanic corrosion. The change interval is 4 years for VCS yellow coolant.

The Volvo Penta coolant VCS (Yellow) must not be mixed with Volvo Penta coolant (Green), nor be used in combination with a coolant filter.

Note: Never mix with VCS yellow coolant with green coolant. Your Volvo Penta was supplied with either Green or VCS yellow coolant. They must never be mixed nor swapped over. Earlier variants of any Volvo Penta diesel are likely to use the green type. Later Volvo Penta diesel's may have been supplied with VCS yellow coolant, and they should be kept on this type. Remember, your coolant should be changed every four years and you should remove the heat exchanger at least every 5 years, if fitted to clean it.

The best way to replace it is to use the ready-mixed version, as incorrect dilution can lead to overheating issues.
