Well, my coolant froze over the winter...

The freeze plug popped out and The coolant all came out. After popping the plug back in, I filled it up with radiator flush and water to find any leaks... the frozen coolant had pushed out at most of the hose/metal tube connections, in addition to the radiator connections.

Freeze plug:


Looks like the chrome coolant tube in between the cylinders on the right side of the engine had the 'o' ring pop off and is leaking. The tube on the back of the front cylinder also popped out and is leaking:





the radiator is fine, I will have to clean off the hoses and tube connectors though:



Anything else I should be worried about or looking for? How do I replace the 'o' ring in photo #1? Still looking for my Clymer...

I am at a loss for words. I thought my Dexcool was all set.. I had a 50-50 mixture, but -20*F temps must be too cold. The bike runs well, but needs a little TLC... no coolant in the oil- I changed that to check after going for a 15 mile ride.

I don't think that was caused by freeze ups. That looks more like cold weather leaks. Just some cleaning and replacing of the o ring should take care of it.

even though the freeze plug ACTUALLY popped COMPLETELY out? I had to put it back in after finding it on the floor..

You are right. It did freeze. If you don't have any aluminum breaks, water in the oil, water in the cylinders, you may be able to salvage it.

If you're talking about the o-ring on the coolant tube/pipe, you will need to loosen the bracket that holds the tube in place (7 or 8 mm bolts IIRC) and pull the tube up to replace it. I'm pretty sure I have some o-rings; PM me if you need one. No charge of course.

we had temps around -20*F and -25*F. wind chills hit 35-45 below. I have a few o rings from when I replaced the tubing when i bought the bike, hopefully they are the right size. it seems to run fine, put 6 miles on it since i put the plug back in and no real signs of damage yet... keeping fingers crossed.. no money for new bike :p

That's really weird. I have a 50/50 mix of dex cool in my 00 Jimmy, and we had sub zero temps with -0 temps with the wind chill, and never even got close to freezing the coolant. And it sits outside.
A 50/50 mix should be good for -35 temps.
