Hi i have type d coolant (genuine green fluids )black bottle ,i need soon to do the big service cambelt water pump and all those ... Anyway my coolant fluids are 2 years old but unopened its ok to use them for the next4-6 years?and how much liters do i need?
 
Coolant should be fine, it's not like brake fluid where you ideally have to use it by a certain date.
It can last for years in circulation in a car's coolant system so in an unopened bottle I think you'll be ok. Someone correct me if I'm wrong though!
