When do we check the level of the coolant? When it's cold or hot?? Mine when I fill it up cold to the max of the reservoir and I go few times for a run it miss it and its starts to loose coolant. I dont have any leaks and my oil is clean. Now it's at min level and when the bike is warm it gets between max and min. This is confusing and I don't know what is happening and what is the right thing to do. I have changed the coolant with motul motocool the red one and I have done almost 3000 km. Any advice will be helpful Thanks
I assume you don't mean at the radiator but the tank under the seat (on my bike anyway). This is an overflow tank and it will find it's own level. As long as you have no leaks or problem with the bike don't worry about it. My speed triple is fine with the level way down the tank.
Check it when cold. If you fill to the max Triumphs don't seem to like it and usually spit out coolant when hot until it finds its own level. As long as it is not below min then everything is fine. When I do a coolant change I fill halfway between max and min.
my coolant line is below min and it was only serviced 3 months ago, is this normal 2023 765 rs How do you get the rad cap off its really stiff
Keep an eye on it but you may find that the bike has found its own level, speed triples regularly run well below minimum Have you tried pressing down as you turn the cap anticlockwise?
@Richard Pennycuick Those caps can be tricky sometimes. Just keep pressing it down and twisting it will come eventually. Never attempt when the bike has been running. And if worried take the over flow tube from the rad neck and just force a little water down it. If you don't know what coolant just use deionised water don it.
I don't think it's the case now but some caps used to have a tiny grub screw for security. Worth checking first.
