Exchanger coolant leak fixed - Fuel tank,Battery removal

[Cody Boesch]

Hi there, went out this past weekend riding ran great all weekend was fairly cold all weekend around 0*F. Saturday night got down to about -15. went out sunday morning/ early afternoon, loaded sled in trailer and noticed coolant dripping down in front of the track on the right side of the sled. Any way this could be leaking down from the hose and down the exchanger fins.. does not seem to be leaking onto the driver like all the people were having seen the coolant on. Ran great 225 miles and then all of a sudden noticed good amount leaking out that area after sitting all night outside.

Its probably same spot.....mine was the rear clamp, front clamp may run down abit further forward, hard to say for sure.

You should be able to get up under there from front of tunnel with a light and maybe a mirror to see where it starts. Mine we barely tight, so cold temps made it leak.

I was hoping that by reading this excellent thread yesterday and tightening up the two clamps would solve my recent leak that developed this week. Pretty easy to pull it all apart. But.....

No such luck! It looks like the actual hose has a hole/slice in it. Maybe from a sharp interior finish?

Has anyone replaced this short piece of hose? I can see it looks like a tight space and probably a bugger to fit on. Any words of advice?

I will be doing that exact repair later this week

I'd like to know how it's done! I have the skid out, header off, two clamps off but can't see how you get that 3" hose off? Local dealer hasn't done this job yet.

The front exchanger is fixed so I guess you drill out the rivets to the right side tube that goes to the rear exchanger? That would give the room to replace?

I plan to cut the old hose and hoping the new hose will slide rearward enough to slide forward onto front exchanger, otherwise, I plan to drill a few rivets to bow the rear nipple down enough to do what I said

You have to drill out ALL the rivets to slide the rear cooler back. Its one piece.

You are correct, I just did exactly that. 23 rivets in total, which include the two holding the tunnel bag that had to come off. No shortcuts in this job!

I have a nice 1/4" rip/tear in the 1.75" hose. Now to get a replacement and put it all back together.

Thank you!

It most likely happens when the sled comes back home,all full of snow and ice,we have had to always bang ice off the sides,and out of skid,daily before riding.Otherwise ice gets in there and can cut those hoses.

did mine today, yup, all the rivets had to go, tried otherwise. rear exchanger was tweeked a little and eventually cut the hose from the inside

I'd order the BOP protector while you have it apart and easy to do.

I have always removed that ice buildup end day, but sled only slept outside heated garage a handful of times over its two season life. Maybe a piece that broke off while riding? I do put in long days so may try removing during the day. Nearly at 10k kms now. Time to put the sled together today, heat exchanger was back in last night and silicone drying.

This is for Travis. Have you ever thought bout coming up with a design to move the heat exchangers right to the outer edge of the tunnel. When I was installing your cover I looked at that and thought if they could be mounted right on the outer edge it would possibly eliminate a lot of the ice build up in the tunnel that is a real pain.

the protector wont help unless it keeps the nipples aligned. the top of the tunnel is weak and when the ice tweaks the rear exchanger nipple up, it eventually cuts the hose from inside. there is maybe 1/2" between the nipples. I think if the nipples were a little further apart it could take the flex. Or maybe a wide band clamp that covered the whole hose to keep it aligned. If I deal with it again, I will cut a piece of copper pipe and slit it to fit over the hose and in the clamps. too bad they didn't just put a threaded union there, but then it would probably crack. maybe a 200hp fan cooled engine?

they are lined up with the windows in the track for a reason
