First the radiator will have to be drained atleast partially or you will have antifreeze everywhere. Second you will have to remove the heater box (which is on the passenger side of the firewall), I believe there are 8 bolts in total. Once you have the bolts out - remove the wire harness to the fan, and then gently pry the heater box cover off. It should have a caulking like substance on it.
Inside you will find the heater core - which has 2 hoses clamped on it once removed there should be a couple more bolts that attach the core to the fairing.
There will be fluid that will spill out but if it was drained in step 1 shouldn't be too much.
The reinstallation process is the reverse.
PS it is much easier to do this without the passenger front fender - but that is a job that will take an extra hour + to remove and reinstall so might not be worth it.
