I have a 2021 Giulia which keeps on losing coolant from the intercooler/ turbo coolant reservoir. Took it to the dealer and they pressure tested it and found nothing. No visible leaks and the coolant level goes down a bit after every drive. Looked at the o ring area and see no leaks either and no visible coolant on the radiator either. Any ideas?

Might have been an air bubble in the system and it is settling, otherwise go to a radiator specialist and have them check it properly

that turbo radiator is very well hidden, it could be leaking from there but you would see stains on the floorpan

can you smell coolant ?

No strong coolant smell at all either, the dealer just filled it back up and it’s back down to half of the tank after 3 drives.

on my '18 QV, the coolant reservoir will expel any coolant over the low mark when cold. Adding coolant to bring it up to the full mark, will just soon result in it dropping to near the min mark, but no lower, where it stays. It self regulates to this, no matter how much or how often coolant is added. Perhaps yours is doing the same. I quit adding coolant, and all well now. NV

Mine just completely depletes, it doesn’t move when the car is off but only goes down after a drive and after a few drives becomes fully empty.

Hello there,

This certainly sounds frustrating. Have you brought this back to your dealer to address that it is still leaking? If not, we recommend doing so. Additionally, you can try getting a second opinion at another dealership. Our locator tool is linked below.

This is an interesting feature I didn't know about if it is also on my 2.0. Do you know if it would self-expel from a bleeder valve or somewhere else? My passenger side always seems to want to stay near low but front driver side reservoir stays at max.

My passenger side

high temp overflow reservoir - engine

front driver side

low temperature overflow - turbo
