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.

Ive used Araldite on windscreen washer tanks with good results .....applied on the outside....held up for 4years plus...til car sold
