Default vessel expansion

Health to all. I am a walter from Italy and I am happy owner of a cbr 1000 f sc21 of 1987. I have fully restored it. I have just one doubt. The radiator expansion vessel is subjected to the thermostatic valve cap. Therefore the refrigerant does not fall by gravity. In case of need, how can the coolant be reintegrated? In the storage tank which liquid to insert? Pure or diluted refrigerant ? Thank you all for the answers. Hello

You can top-up coolant by pouring it into the overflow tank, but if the bike was totally drained, you should add it directly into the system by filling at the radiator cap. It is located under the tank near the front of the bike. That's what I'd recommend

Make sure to check the fluid level after riding it a couple times. Sometimes air needs to escape so it may need to be topped up again afterwards

You should use premixed coolant, or else you can use the concentrate mixed 50/50 with distilled water

The manual has more detail if you're stuck. Hope that helps

When the engine cools, there will be enough vacuum to suck the coolant back past the cap seal. Use 50/50 water to coolant in both radiator and expansion tank. Make sure the coolant you purchase is not pre-diluted to 50/50, there are some on the market.

I have used pre-mixed in mine, saves having to get distilled water and you don`t have to worry about ratios.

The water used in the 50/50 mixes is much cleaner than anything you can buy.

You are both correct. I botched that post.


It should have read,

Read the label of the coolant because some coolant is premixed 50/50. Don't dilute it further.


I have also used it. I have also mistakenly added water to it and had to toss it out.
