Coolant SG

[101RRS]

The service life of the OEM coolant in the 2.7TDV6 is 10 years but the caveat is that at each service the Specific Gravity is tested and if outside specifications the coolant is changed - I wonder how many dealers actually do this test??

I have searched but cannot find what the required Specific Gravity range is for the coolant.

Anyone know what it is?

Thanks

This looks to have the correct specification as the manual WSS M97B44-D

[101RRS]

Thanks for that - good information.

However I would have expected an acceptable SG range at a given temp and concentration.

Also - does anyone know what concentration the OEM coolant is mixed to.

Thanks

50% coolent + 50% water me thinks .

Reading this post today and doing a bit of follow up research I am of the opinion that using a 50-50 mix of coolant is for no other reason than meeting European requirements in winter to have a -40c rating on the coolant.
Is that how others are reading things?

Infact if your coolant mix goes beyond 50-50 you loose heat transfer efficiency as well

Should have attached this file as well.

So I take it that the OEM coolant is Havoline XLC?

I also believe this - I still use the 50/50 mix though just because this engine is a fickle bloody thing when it comes to its fluids.

I use Nulon OAT coolant concentrate in mine. It conforms to the same standards as the LR spec. Def don't use Ethyl Glycol, same as in most euros!

Putting aside having to drain the coolant for maintenance issues and assuming SG tests come up OK there should be no D3/D4/RRs that has needed to have its coolant changed.

That's right - I had to drain mine when I did the timing belt :)

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. :-(

According to this document it seems so.
