custom coolant recovery tank
 

Here's a cheap and easy to make coolant recovery tank.
You can use any diameter or length pipe to suite your needs.
I used 1-1/2" pvc pipe
2) 1-1/2'' id end caps
clear tubing
2) npt barbed ends and some thread tape
Cut the pipe to length...you need
drill a hole in the center of both end caps
tap threads into the cap, I used a flare tap, and tapped so that the barbed fitting fits tight into the first couple of threads...that way you get a tight seal
tape the threads of the fittings and tighten them into the caps
use pvc glue and spread a thin layer into the ends of the pipe and assemble the caps into place.
Let the glue set for a while and attach to the bike.
The bottom tank fitting connects to the radiator over flow nipple just under the cap, the top tank fitting is a vent, that should route some where below the engine.
add a little coolant to the tank, that's it.
I got the pvc pipe free, I already had a tap and tape, so all I had to buy was the end caps, I spent about $5.00 on the whole thing.

That thing's gnarly man! I built something similar, only much bigger to go in my car when I was trying to produce hydrogen.

I still love your white plastic.

Those are some sturdy looking radiator guards, are they aftermarket? My xc 300 had nothing like those from the factory.

Yes, made by MECA, and they are pretty beefy.

I ride with a guy that has a home made hydro van, the system looked scary when he fired it up
Tks on the plastics, Ya everyone else seems to like em too.

Where are your graphix from?;)

Ride pg, but I had them change-up their existing pattern, basically pull out all the red

Nice setup. I have had three GG 300's. The first and this last one have the expansion tank behind the number plate and not one time have they ever spit any cooloant and I tend to ride really slow technical stuff. I know some guys don't like them but I have had great resultls with them. Brian H set this last bike up and added some rub protection to the expansion tank with a thin layer of JB weld.

I only have overheating issues when the trails are super muddy and I'm baking the clutch on some slimy up hill.

Great mod man , if the new models don't have an overflow tank i'll be doing this mod when i pick up my button start ec300 . Cheers!
