then you refill with an appropriate coolant like Havoline and you follow the instructions with respect to life span etc and the Landrover service cycle does not apply.
However my car is now 6 1/2 years old, still has its original coolant which looks great but as I service most things myself I would like to test it every 12,000km to ensure it is OK - the test is easy but no one seems to know what the test numbers should be for the OEM coolant. The Havoline seems like a good product and I actually suspect it is the OEM product.
However you doing the belt does highlight, why did LR give the coolant a 10 year life when the belts have to be changed at 160,000km or 7 years anyway - maybe LR are suggesting you catch the coolant as it drains out the engine and you reuse it. :-(
