Battery coolant replacement

[Steve Kaye]

I have a 2022 ZS EV
The MG dealer says that at the 4 year old mark, the battery main battery coolant has to be replaced, irrespective of the mileage the vehicle has done ( it will be approx 40,000)
Approx cost is $NZ 1,000 ( about 500 pounds)
Does this sound right?

It's 5 years or 75000 miles (120000km) over here.

Here it is also done at the 4 year service.

I would imagine the £500 is the full service, not just the system flush and replacement of fluid ?
