Ok thanks, I’m just preparing to change this water pump cover and stuff and I was told that I need to drain the coolant/radiator to do this and to fill it after I’m done. Do I need to access this cap for that?nope hasn't got one the rad cap is on the top of the thermostat housing. it's the highest point in the system.
Would u happen to have a pic of this?yup.
I’m gonna have to study this. Thanks
So is this where I would fill the radiator back up after draining it for the water pump procedure?Once you remove the main fairing, the thermostat housing with the radiator cap is on the left side of the bike at the front.
You can see it on the left side of this pic.
Correct.This is so it I’ll flow rather than trickle right.
Ok, last thing. Just want to make sure I do this right. This my first bike and I don’t want to mess her up any further. I read from another thread that “bleeding the system” was part of the process as well. I suppose this is done by revving the engine a little?Correct.
When filling the system, fill at the thermostat housing and also the reservoir. After your back up and running, recheck the reservoir level after each ride a few times (after the engine has completely cooled) and top off as needed. Reservoir level will drop for the first few rides.
Yeah I was kinda thrown off by that phrase as well. But he said it was to get the air bubbles out.To be honest, I've never heard the term "bleeding the system" pertaining to the cooling system. No need to do it with the engine running. I like the squeeze the coolant tubes while doing it just to help get some of the air out. But even this isn't a must do part of filling the system.
Gotcha, that’s good because I was about to ask you what coolant tubes you were referencing.😃In a nut shell. All you have to do is get close when filling the system. Then as long as you keep your eye on the reservoir tank for a while, you should be fine. The reservoir tank will continue to replenish the system, and remove the air from the system for a few heating and cooling cycles.
I assumed it was the one running from the thermostat where the cap is located.Yeah I was kinda thrown off by that phrase as well. But he said it was to get the air bubbles out.

pardon my interjection but "bleeding the system" is a term used to remove air from the system. usually from the highest point in the system but the EX's highest point IS the filler cap. so not required as long as you make sure all the tubes are full as @bpe stated.To be honest, I've never heard the term "bleeding the system" pertaining to the cooling system. No need to do it with the engine running.
Makes all the sense in the world to me. Thanks to the both of you. 😅
