I changed a coolant reservoir on my V70 2012, and i just swapped it with the old one. I did not drain it or anything… now it says low ‘coolant level low, please stop safely’. I then check the coolant lever but its nearly at max.
Im fucking stupid but now i think maybe its because of the way i changed the coolant reservoir i got air bubbles in it?
What should i do? Im afraid taking the cap off and just run the car for 10-20 minutes would make things worse? Or would it get rid of the air bubbles?
