Looks like my coolant tank / reservoir may have sprung a leak. Can it be removed without removing a lot of stuff? What's the easiest way to get it out? TIA.

Difficult to remove tho i believe people have done so loosening the mounts....i recall also someone heating the bottle to aid removal....search coolant tank removal

I should add the mounts i referred to were the engine mounts to drop the engine foward..

As a newbie to the CX, I wanted to thoroughly clean the crud out of mine. You can’t remove it as bahn88 said without moving the engine.
But, I removed the two bottle mounting bolts and was able to rotate the bottle. So if you have a leak, you should be able to get to most seams with the bottle still on the bike.

A soldering iron may seal up a minor split or hole. I’ve done that successfully on poly chainsaw gas tanks before. The tank should not pressurize.

Posts 4 and 5 offer good information
If you can identify the area and the leak is small a good adhesive applied to fill in the gap would also work once the bottle is flushed and dried in-situ on loosened (bottle)mounts.....

Perhaps place a plastic bag inside the reservoir adhered with silicone adhesive?

I haven't had good results with adhesives on polyethylene. Nothing sticks to it. Heat welding is the way to go.

You need to use a polyethylene specific adhesive ....most of these will do both PP and PE...however they are fairly pricey.
These were discussed in a previous thread on plugging an airbox.

I've repaired a number of them with a Selleys product sold in Australia called araldyte. It's a 2 part epoxy that mixes to a consistency like honey and does appear to bond to the material.

But you have to dremel the crack out deeper and wider first.
