windshield washer reservoir
 

Somehow still able to use the windshield washer fluid

They damaged it

How they damage it? It's pretty well protected behind the bumper. OP, where you live at?

Could hitting a pot hole could've done this?

Rusty, I'm in New Jersey.

plastic weld or glue it back together. surely it's not cracked into two pieces but who knows... you can pull your fender liner and check it out for yourself.

Which dealership did u go to? And did you buy your car new or used?

Northern climate. Did you ever put just water into it? No washer fluid at any time? If you did. I'm then thinking that it froze and cracked.

And no reason to pay the dealer $300 to replace it. If you can't repair the crack a replacement tank is about $125 shipped and maybe an hr of your time to swap out.

$10 for an aquarium silicone sealant at home depo

Is this something a beginner could do?

Nope, unless the previous owner did, car came with roughly 1200 miles though.

Do you have a standard tool set with metric wrenches/sockets?

I repaired a crack on my old frontier using a plastic jb weld. Sealed it right up and never had to revisit it. What's a tube cost less than 10 bucks?

Yes. The hard part will be getting to the bottle. The FSM has exploded diagrams and procedures.

Those I have

Came across that link on Google. But I'm hoping I could get the crack sealed otherwise I will have to get it replaced. Also, my car was bought from a dealer in WI.
