I have a 2011 veracruz that just spilled an entire gallon of wiper fluid when I filled it up. Pretty sure it's cracked. I'm somewhat new to fixing things on my car but I'm trying to save myself some money if possible. What tools would I need to do this job and how would I do it? I've read some other hyundai threads and I know I have to disconnect the battery. But instructions can be different for different models of cars so here I am.

 

If you are sure it is cracked, you could always get a new bottle from Hyundai. They could be the most expensive for a new container, but you will get the right part the first time and that is worth something.

If you can see the crack , you would remove a few fasteners clean the cracked area,and apply a special adhesive made for that type plastic because most usual adhesives will not stick to the material the bottle is made from.
If you purchase a replacement you will only remove and install once, Any other way there is the chance you will be doing the repair more than once.

 

It is cracked just not fully. I can't see the crack but it spilled quite a lot of fluid out when I drained the entire gallon of wiper fluid in the reservoir. However, my fluid light isn't on yet so a decent amount must still be in there.
