I thought in the days when there were just really two types - ordinary and that for ally, you could use the ally stuff in cast iron. But it was considerably more expensive. > I do know that the dealer services VW landrover volvo jaguar and they > keep a different type for each make. > Just phoned them. > This is the one they use for landrover only http://www.caltex.com.au/ProductsAndServices/Pages/ProductDescription.aspx?ID=1645 That certainly looks suitable. > Its surprising that coolant/anti freeze comes in so many varieties. Indeed. And that we appear to have gone backwards in that some of it can cause damage, rather like the early stuff where they said to replace it with plain water when not needed for frost protection. -- *Always remember you're unique, just like everyone else.

Anyone know >which brands are suitable? Land Rover use an OAT type coolant in a 50/50 ratio with water, for the V8 and the TD5, earlier engines may be OK with different types. It isn't cheap, but we've used it in our Disco V8 after a new short motor fitment last July and it certainly keeps the internal ali parts free of any signs of corrosion. We changed a timing gear in december after 10000 miles and there was nothing at all in the way of corrosion on the water pump internals.

Don't think there's a problem with ally engines and 'new' anti-freeze - it's the copper rads and heaters fitted to older cars. Modern ones use ally. -- *Where there's a will, I want to be in it.
