The Coolant light came up few days ago,I checked the expansion tank and noticed thatthe level of the coolantis below the MIN.
I was in hurry and had to add about 700cc of boilded water. I am going to flush the coolant in next few days, however I have a question, does anybody know if I have to use VOLVO coolant or any Brand name ( Good quality) of coolant works?
99 S70 AWD ( Used to be AWD, now it's FWD!)
Second, I have the car for 3 years and I am not sure if the coolant has been changed at all ( 221,000 Km), is this means that I may have some leak?

 

Any good brand of coolant should be fine. Make sure you mix it to the right ratio.
