MGZS EV Radiator

[Scriv]

I was making a rare inspection/check under the bonnet and realised that there are two coolant expansion boxes with black caps that require periodic checks.
I'm curious........are both systems, the Battery Coolant and the Electric Drive Systems connected to the same radiator?

This is common practice with ICE cars - so nothing new in EV land.

Although it looks like there might be 4 connections into a single rad, in practice the 2 systems are separate - with the coolant from one unable to mix with the other. If they were to mix then there would be problem. Some time ago, Mercedes had a bad batch of radiators which failed allowing coolant to mix with auto transmission fluid!

Thanks Robert, you have satisfied my curiousity!
