01 rm250 coolant problem

[jclark15]

Hey tt guys I'm new to the forum and also to the world of rm's. I just bought a really clean 01 rm250 and the thing runs like an animal but the one thing I don't understand is the radiators. When I looked in the radiator to see the fluid it was like 1/2 under the top of the veins so I added some till it was at normal level but when I started the bike it puked all the fluid I just put in. And it wasn't after heat built up it was as soon as I started the bike. Don't really know what's going on.

Any help is much appreciated

Does anyone know anything about this issue.

Is it normal?

It almost sounds like your radiator cap is bad. It's allowing fluid to drain at too low of a pressure. Or maybe an aftermarket cap that's designed for a different operating pressure.

maybe you put too much in

[jclark15]

Yeah I saw that somewhere else as well so that's the first thing I'm going to try

Ok I got a high pressure cap for it and I filled up the radiator and it still puked out some fluid and after I popped the cap and the coolant had like a blackish tint

Maybe you just overfilled it to much, is it coming out of the overflow, cap, or a leak maybe?

It's coming out of the over flow
