The manual is extremely vague on this issue. I have just checked the levels of the two small coolant tanks under the frunk RH side. One appears to be the coolant level for the REX engine and is fine. The other states it is for the A/C system and seems quite low.
What do I top this up with? The manual gives no information except ‘coolant’. I see i3/i8 coolant can be bought online but is that the stuff that goes into the A/C coolant tank? Thanks
