Each vehicle manufacturer has a certain coolant they use due to additives in the coolant. It is important to try not to mix colors or use just water as it can cause issues such as rust build up, overheating, and premature failure on cooling system parts.
Generally speaking these vehicles take this type of coolant:
VW/Audi- Dependent on year, Phosphate Free Coolant G12 Spec (Pink/Violet Coolant)
Subaru- Dependent on the year they use either regular green, long life blue with Subaru additive, or long life green with Subaru additive

Some manual transmissions require a higher performance fluid which has extra additives and some require a different viscosity. Always check your owner's manual or with your mechanic to ensure you're using the correct fluid.
