Yup, every time I take the LR4 on a trip I fear I’ll be stranded due to a cooling issue. It really is a poor decision to use plastic that just rots out in heat, especially in the summer here in California.

Although both JLR and Dexcool are both OAT, I still don't recommend mixing coolants. I had to completely flush out the coolant until clear including the rear hvac for about 7x before switching over to dexcool. Pro tip, just flush with water until clear and on the last drain you can fill with 1.5 gallons of concentrated dexcool. It comes out pretty darn close to a 50/50 mix considering LR4s with rear hvacs have about a 3 gallon capacity.I mixed the Land Rover coolant with Dexcool and it seemed fine. Is there any damage that occurs from doing that? I actually liked it better with Dexcool because it has a stronger pink color that contrasted well with the reservoir and it was quicker to spot the fluid level.
