I want to try some JB Weld for marine plastics to repair the leak. The leak is about a 2" slot from rubbing on nearby metal. Thought I would try. Messicks has a tank for about $100. Has anyone experience with repairing plastic with jb weld?

There are a lot of different styles of "universal" coolant recovery tanks that are far less than $100 and you can probably find something that will fit the existing space/mount method.

Thanks for the the reply. I have looked at other tanks available. Though the space in the tractor is a narrow flat slot of about 1 1/2" x 8" in a rather convoluted shape. I'll try the JB weld as Jason has had a positive outcome. I'll give this a shot and get back with the results.

Anyone know the type of plastic used in making these tanks?
"Low surface energy" plastics usually require special adhesives/epoxy. A few weeks ago had to do some repair work on a product called PlasTeak. Basically a HDPE or HDMW plastic. A low energy plastic that would experience significant shear and impact loads. JBWeld for plastic would not have worked. Neither would Loctite brand of plastic specific adhesive. Have some UV cured for "plastic" epoxy/adhesive, but did not specifically list the poly plastic being repaired. Ended up spending $$$ on a product from Permabond. One of their TA46... series products. 3M supposedly has an adhesive made for some tough to bond plastics.
There are also plastic "welders". But clueless if that would be a good option in this specific situation.

I went the route of repair for the expansion tank. Took the tank and washed it, then applied JB Weld Plastic Bonder to the grooved out void. I used a wooden off cut to smooth out the pour even with the surface of the tank. So far so good! I've checked on it every day and there is no leakage of fluid.
In the past I have used a plastic welder on a gas tank for a mower. I was surprised how well it turned out. 2 years later it still holds gas with no leaks.

Another too late thought. Forgot that I have a ski/snowboard base repair "welder". Purchased years ago and haven't had a need to use. Came with some P-tex sticks and ribbon for repairing damaged ski/snowboard bases. Back in the old days use to just light the Ptex sticks like a candle and let the melting stick material drip into the damaged section. Real inexpensive option if compatible plastic. But still clueless to they type of plastic used in these tanks.

I always use my 100W Weller iron to 'weld' the crack,with lots of 'hills and valleys'. THEN use a 'plastic' rated 2 part epoxy,letting cure for at least 24 hours. Zero issues for the past 3 decades. Anything(most ?) made of plastic, generally has a triangle or other marking and the name of the plastic it's made from. PS for PolyStyrene, PC or PolyCarbonate, etc. makes it easy to get the correct 'glue' for the repair. The 'glue' for car bumpers works really well on almost all plastics.
