Good Morning xBhp!!! This is Kripz from Chennai. I own a Yamaha R15 V2.0 which is 4 months old now. It's awaiting it's third free service soon. I noticed that the coolant oil in the coolant reserve chamber is below the minimum mark. When I asked the service experts to refill it, they mentioned that the refill is not necessary and the amount which is in the reserve chamber is the correct level for the bike. The coolant is in the same level since the second service and it has not reduced from that level till date. I am not convinced and I need some knowledge in this matter. So, will the radiator and the cooling system work properly with the coolant oil being below the minimum mark? Any advice and insight will be much helpful. Thanks in advance.
