Volvo Penta VCS-2 Orange Concentrate Coolant 5 Litres, Part Number 24712781

Volvo Penta VCS Orange Coolant Concentrate, 5 Litres, Part Number 24712781

Volvo Penta Coolant VCS-2 (orange) contains new inhibitors that are adapted to the materials used in modern engines. VCS-2 (orange) offers improved protection against corrosion and the build-up of deposits. It helps counteract cavitations and galvanic corrosion. The change interval is 4 years for VCS orange coolant.

The Volvo Penta coolant VCS-2 (orange) must not be mixed with Volvo Penta coolant (Green). It can be mixed with yellow coolant.

Note: Never mix VCS-2 orange coolant with Volvo green coolant. Your Volvo Penta was supplied with either Green or VCS-2 orange/ VCS yellow coolant. They must never be mixed or swapped over. Earlier variants of any Volvo Penta diesel are likely to use the green type.

Later Volvo Penta diesel engines may have been supplied with VCS orange or yellow coolant, and they should be kept on this type. Remember, your coolant should be changed every four years on VCS and every 2 years on the green type, and you should remove the heat exchanger at least every 5 years if fitted to clean it and replace the O-rings.

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

Background 
VCS-2 is backwards compatible and can be mixed with the yellow-coloured VCS coolant.
VCS (yellow) has been in use for several years, VCS-2 (orange colour) is a next-generation coolant and was developed by Volvo Penta Group to replace VCS.
VCS-2 has been extensively tested to meet the requirements of the industry
standards ASTM D3306 and Volvo Group Standard STD 418-0007, to guarantee optimised performance in Volvo diesel engines.

VCS-2 is based on LoBrid Technology (90% Organic Acid Technology /10% Inorganic Acid Technology), and provides improved coolant oxidation stability, less metallic corrosion, and better rubber/plastic compatibility. The inhibitor package in VCS-2 is free of 2-EHA and meets regulatory changes with higher demands on removing toxic components in the coolant to improve health and the environment.

VCS-2 has the same service interval as VCS and can be diluted to provide the following protection:
• 40/60 that provides antifreeze protection down to -25 °C
• 50/50 that provides antifreeze protection down to -37 °C
