No crusty white stuff anywhere and because it has been 5 months since the last top up, they tried to convince me this is normal and nothing is wrong.

I persisted and they’re using a pressure thing to try to find the leak then replacing the tank (so it has a new seal and a new sensor thing, since my sensor didn’t beep to tell me it was so low).

Do you think they were trying to get rid of me :(

I noticed because the coolant was topped up in May and it’s empty again. The heaters weren’t working - now topped up, they’re toasty again
