So, whoever did the timing belt should have changed out the coolant. Can you ask them?
Never heard of clear coolant. Maybe too much distilled was added?
I could ask. Its a reputable import shop in the area that i had do it. I just don't know if they would remember, but they probably use the same stuff every time in the tdi's...I'll ask. I assume whatever it was its g12, but idk 100%
I wondered if it was to thin but i ran it all last winter even -35 and no problems, so i think its ok. It smelled like coolant and i accidentally burned my arm with it a bit when i got some on me in the proccess.
I'll ask the shop and see what they say. Was mostly curious if anyone has seen such a thing because i have never heard of it. It definitely wasn't green or orange. If it was pink it is super clear
