Question about 1991 Toyota 4Runner

1991 4Runner Windshield Water Tank--More Sieve Than Tank

I noticed this week my windshield washer tank was dry so I tried to fill it this morning. Basically I watered my driveway in the process so I'll have to either replace/repair. Given the age of the vehicle and this is not a must-have feature, I am thinking of just patching the hole.
Q1-It looks like this just bolts on/off with some hoses on the bottom. Should I be aware of any "got-chas" or is it really as simple as it looks?
Q2-I have some marine-grade fiberglass tape and epoxy from another project. I was thinking if I clean the tank well, sand the area lightly and then patch the outside, it should hold.
The motor works fine if I quickly test it before all the fluid drains out so I am trying to not buy a replacement part if I can help it. Of course I won't know the exact size of the whole until I can look at it.
Thanks for any help--Ward, Dallas.

    Thanks for the input. I had to put the car into the shop for some other problems (power steering pump) and the mechanics threw some epoxy and sealing material over the hole in the water tank. It seems to be holding. At close to 300,000 miles, I think I may be on my last legs with this vehicle, but it has served me well.

There ar no hidden "gotchas". Just unbolt it & take it out. Be careful when extracting it, though, you may have a "brittle" tank, and handling it roughly may cause it to break further. Older tanks' plastic tend to lose the resiliance, and they crack & break apart.

Add windshield washer fluid to my 2013 spark? The Neck fills up and then no fluid gets to the tank... How do I get fluid to the tank?

You either have dirt in the spray head that sprays onto the windshield and is not letting the fluid pass from the reservoir...or you have frozen water in your lines that is blocking it from working. Either get a hair dryer out and warm the tank, fill hose and spray lines up or get the car into a warm garage to see if it is ice. If it doesn't work then.......I don't know...

check hoses that run from the washer pump to windshield and also the ones that lead to the reservoir tank. Something is broken causing there to be no spray.

Windshield wiper washer tank leaking

If you can see where the leak is and it is in fact on the tank, remove the tank and clean the area thoroughly. Let dry. Then get some two part epoxy and mix well. apply to the leaky area and let dry. Before replacing, test the tank by filling it with water. If it doesnt leak, re-install and fill. if it still leaks, repeat the process.

No windshield fluid is coming out for my rear window. My front windshield works fine. What's wrong?

They usually have a separate tank at the back of the car, have a look at your car's owner's manual and see where that tank is located, fill it with water (if you are not living in a cold area) or windshield wiper fluid.

Where do you add windshield washer fluid for the rear window in a 1998 chevy venture?

Hello, the washer fluid fill is the same as the front windshield washer tank. They use separate pumps though. If you are not getting any fluid to the back glass when you try it, you may have a restriction or either a bad pump. Please rate my answer, thank you.

Have a light on dashboard that looks like windshield wipers

Check your windshield washer fluid level.  The washer fluid tank has a level sensor in it.  That could be why that light came on.

Windshield washer reservoir tank is leaking how do I replace?

You must remove from it's mount and empty out any fluids that is in tank.fill the tank with water and locate where the leak is coming from. wash tank a few times and the let dry upside down. Get some sand paper (80  grit course) and sand area where leak is, clean area with a vacume or clean can buy a 2 stage epoxy that comes in an injection form and squeeze it out on a pc of paper and then get a q-tip and mix the 2 components together, fill the crack or hole generously with the q-tip, if you have to,let dry for 24 hours and mix more and put more on. let dry another 24 hours, replace tank back in it's place and you've solved your leak. (epoxy does wonders if its used properly.
