I started to smell coolant after turning off my bike a few days ago with no drips on the floor. Today, I pulled the plastic and looked in the V behind the reserve tank and saw that an area where one of the hoses connects to the thermostat looks to be leaking. Here is a picture from the other side of the bike.



You can see the leak behind the thermostat on the right side.

So my question is, how hard is it to get to this area to fix?

or maybe the real question is how easy is it the mess up the stuff I have to take off to get at this?

Thanks

Worse case you remove the air box and throttle bodies to get at it as in see shop manual about thermostat replacement. Big job. There is a chance you could get a long screw driver or wrench in there before you have to remove everything. You might get lucky, depends on which way the hose clamp is orientated.

Not worst case. You WILL have to remove the throttle bodies to get to the thermostat housing. I've had to do it twice now. It's a day job.

You can leave your throttle bodies in, but the fuel inj. rail needs to come out, as does the bracket holding your tps. You might even beable to sneak down without pulling your tps bracket.
If you pull off your right fairing and look into the frame into the vee, you might beable to sneak a wrench onto the clamp... iirc they are 8mm.

Day job my ass, can be done in two hours (assuming you're used to tearing bikes apart).



My video doesn't show assembly, but essentially installation is the reversal of removal. To get the throttle body back onto the boots it's a good idea to use a rubber safe lubricant like WD-40 on the boots. Then you use a rubber mallet to thump the whole assembly down onto the front boots first, then the rear boots.

I'd rather pull the throttle body ass'y than disassemble it on the bike. And kaldek is correct, if you're used to working on your bike it's only a couple hour job.

Well I have gotten this far. Found a broken vacuum fitting looks like some one tried to glue back together.

Well the broken vacuum fitting is off the valve assembly bypass control solenoid. Some what expensive to replace.

Can't do anything more tonight. My long screwdriver is a little to short and I have to head to work in a while.

Well I bought a long screw driver and removed the throtle bodies off the bike. Then removed the hoses connected to the thermostat. On the website I was looking at, the hose I need to replace have 2 part numbers. 19528-MCW-H00 and 19528-MDG-000. Does anyone have an idea which hose I need. The clamps look ok, should I replace them also?

I use some 3/4" heater hose from the local parts shop. It's not technically correct since the Honda parts are pre bent but it's close enough that it works. I would reuse the hose clamps if possible.
