another downvote for dexcool
Apparently, DEXCOOL was never the standard fill when the AJxx series
of engines was used in Range Rovers. The AJxx engines were first used
in Range Rovers in the 2003 model year.
My reading would be that the Range Rover engineers had a few years
to observe the use of DEXCOOL in Jaguar AJ27 engines introduced
circa 1999.
Instead of DEXCOOL, Range Rover engineers opted for Glysantin G48.
Maybe they liked the color ... it's blue

Actually the RR used the BMW M62 from 2003 through 2005 model years, U.S., and went to the Jag engine in the U.S. 2006 model year (2005 European model year).
Keep in mind that Ford bought LR from BMW, which only owned LR for a short time before passing it on to Ford.
The BMW coolant is the blue stuff.
I'm about to replace the coolant system on my 2003 RR for the 2nd time, it needs a new radiator, reservoir and hoses about every 5 or so years, or things start to grenade.
The Jag-powered, Ford-improved models of the RR are generally more liked and reliable than the BMW era models.
It's too bad Ford sold the JLRgroup to Tata.

It was a period of dramatic change, not only for LR, but as you know as a Jag fan, for Jaguar too.
LR went through major design changes under the brief BMW custodianship, but by 2003 MY US when BMWs Range Rover design hit the showrooms, LR was already passed on Ford.
Ford had begun their design changes to the LR line, but kept the production of the BMW lineage going until they integrated the Ford-influenced designs into the production lines.
Most of the Ford influence was focused on the mechanical, reliability and quality of the JLR products.
That was a time of monumental turn-around for quality of the Jaguar and Land Rover brands, over 10 years ago.
With that transformation building a new base, shedding the dead weight of legacy Jaguar and Land Rover histories known for unreliable quality was a long, tough road.
But now a decade later, JLR is successfully building a completely different legacy for the new generation of JLR.
Ironically, it's gaining trust from improvements that were driven into the product under Fords stewardship, while under Tata's ownership.
Tata's is benefitting from Fords investments, but on the other hand, Tata appears to be a responsible custodian for the brands, hopefully building on the positive direction of the improved reputations until the time they sell JLR, hopefully at a healthy profit to what they gave Ford.
I apologize for droning on about things that I'm sure you know as a Jaguar owner. I just admire what Impact Fords ownership contributed to the JLR brands, and the vehicles that are being produced now. Impressive. I'll talk about it at any opportunity.
