Question replacing Merea Weekend wiper tank

Hi!

A few months ago I bought a Marea Weekend and after a while it started leaking "fluid" .. first i thought the radiator sprung a leak, but it turned out to be the wiper water tank (pheew). A/The previous owner or garage tried to fix it with some sort of black gunk to seal the leak (it looks like car industry glue), but it came loose apparently... it's all around the valve of the tank so i can't really see if it's the valve that needs replacing or the whole tank... I'm guessing it's going to have to be the whole tank because some of the fixing points are also broken or fixed in place with zip-ties (gawd!)...

BUT...

I tried to take it out.. In my head I could hear those smug Italian engineers laughing at my futile attempt, so put it back and came here. I read here it's a real pain in the *bleep* to replace one... I had hoped I'd be able to remove it "just like that" ..but how wrong was I????...

Does anybody have instructions on how to remove the side body panel of a marea? Or (please please PLE-ASE) let there be a method so that I don't have to do that?

I did manage to find what appears to be a complete technical manual for the Marea on this site, but haven't been able to locate the water tank in it.
(slow site, HEAVY pdf's and also has manuals for different model Fiats!!!) :

w_w_w.fiat-bg.c_o_m/Downloads/Books/
and
w_w_w.fiat-bg.c_o_m/Downloads/Software/
(sorry, it's my first post, not allowed to use URL's yet)

any suggestions / solutions / etc. are VERY welcome!

Cheers,

David

Re: replacing Merea Weekend wiper tank

hello, it's really easy to take the tank out, but it's quite involved so allow a half hour or so, and don't worry, no body panels need to come off
you need to jack the right hand side up, take off the wheel, then remove the screws holding on the front wheel liner. just the front part, the one will the louvered grill on it, the liner behind the wheel can stay in place
moving to the top side, there are 3 screws that need removing from the tank itself, (be aware that one of the screws also holds the coolant fluid resevoir in place) if i remember correctly, two are easy to access, but the one near the pump will require a very long screwdriver, very thin hands, or a small socket set extension to reach.
after you have the screws holding the tank out, you can just pull upwards on the pump and it should pop out with no trouble, its not attached by screws, then with a little wiggling the tank will pass DOWN through the hole in the bottom and out through the wheel arch.

upon removing and inspecting the tank you will note that the lug holding the bottom screw in place is rather badly designed, and most of the weight of the tank weighs down on this lug, in my case, there is a hairline crack below this lug which leaks when the reservoir is too full (the hairline crack opens with the weight of the fluid). My tank also leaked and i have made 3 attempts to fix it, first time i tried with a smudge of silicone sealant but i couldn't get the tank clean enough and the silicone wouldn't stick well enough, second time i tried some epoxy glue, but the weight of 5 litres of liquid on this lug proved too much and the glue cracked, 3rd time i used a fiberglass and resin kit to seriously reinforce the lug and to seal the leak. no problems since. touch wood.

EDIT: with hindsight i should have tried to find a brand new replacement tank before using the fibreglass kit, and seeing as yours has been butchered i suggest you do the same.
Thanks loopymind thanked for this post

Re: replacing Merea Weekend wiper tank

thank you SO much for your guide to remove the water tank!
I'm not going to bother with trying to fix it. I was going to use epoxy, but after reading your experience with that, i'm going to order a new one. actually found a scrap one that's just 5 euros!

When the tank is out, I'll see of I can come up with some sort of easy solution so that the tank doesn't rest on that bottom lug. perhaps a nylon belt where the tank rests on and carries the load when full. I'll post pictures of that when I get around to installing my new tank.

Also, I found the instructions on replacing the tank on that website I mentioned in my previous post. It's in: Volume 2 -> electrical equipment -> page 49/50

thanks again for the quick answer and solution on how to get the tank out!
