Hello everyone,

My 2021 JLR 2.0 is about to get new coolant change. Now i'm still deciding between flush and drain because i'm not confident with the old coolant as it could be mixed with other brand before when I took it to local mechanic shop. They usually top up coolant for customer when they see it's a bit low but they never care about compatibility, however, they do care about the color (OAT, HOAT...etc). Will drain remove more than 50% of old coolant ?

Normally, I get 93-95 celsius on city drive and 95-103 celsius if I smash the pedal hard on highway (high speed, overtake).

Do you suggest drain or flush ? Thank you beforehand for your input everyone!
