Tenpin Posted June 3 Share Posted June 3 Hi Hope someone can help me with this. I live in Turkey and the local Yamaha dealer/service agents aren't any help. I've had the XMax scooter from new (2019) and never had the coolant replaced. I had a split pipe in the coolant system at its join with the reserve tank, resulting in the reserve tank emptying itself. I've fixed the pipe, but the coolant that dripped out was an orange colour. Yamalude coolant appears to be blue coloured, so I'm not sure what type to top it up with. Anyone with any idea what coolant I should use? Any info appreciated. I don't really want to flush the system and refill, but will if needed. Quote Link to comment Share on other sites More sharing options...

I'm also surprised that only the capacity is listed in the owners manual and the coolant spec. Quote Link to comment Share on other sites More sharing options...
NE0 Posted June 4 Share Posted June 4 A quick google search reveals that: Orange Coolants are also known as OAT coolants. OAT coolant stands for Organic Acid Technologies and is specifically designed for newer vehicles that contain more nylon or aluminium parts in them. whereas blues and greens are typically ethylene glycol based coolant. What it does go on to say though, is you shouldn't mix the colours. Quote Link to comment Share on other sites More sharing options...
