If radiator is a little low, will antifreeze make it in if I just put it in the overflow tank? The antifreeze will suck into the radiator when the engine cools down right?

I really don't want to pull the faring and then the tank to get to the radiator cap.

Thanks!

You can add a bit that way, but if the expansion tank is completely empty there's a chance the radiator is so low with coolant that it might let the engine over heat. If you do fill it that way run the engine until the temp gauge comes up about half way, then fill the coolant expansion tank to the top. That will allow the system to suck in the maximum amount into the radiator. Once the engine has fully cooled check the expansion tank and refill as necessary. You'd need to do the heat and cool cycle once more to make sure the expansin tank stays full.

One thing to consider is where did the old coolant go? If you're losing coolant it's going somewhere. It's normal to lose a very small amount over time but if the expansion tank is going dry there's a leak somewhere, either in the plumbing between the radiator to the expansion tank, somewhere in the cooling system or there's a head gasket leak.

You do not need to remove the fairing, just the false tank to get to the radiator cap. You may need to remvoe the fairing lowers though to get a good line to the 2 front 10mm bolts of the false tank and of course remove the seat to get the 2 rear 10mm bolts for the false tank.

I agree with Paul, you may have a leak somewhere that can only be checked for by removing the false tank anyways.

I don't think it is a leak. Just evaporation.

Thanks for the replys.

Add some to the evap tank, it'll suck it back into the radiator. However, I found out the hard way coolant won't fill the radiator if there's a fair amount of air in it.

Yup: I have never removed my fairing, but I've had the tank off a number of times.
