Has anyone modified or moved the windshield washer fluid reservoir for more wheel well clearance?

[JT 07LTZ]

I went from 275/60/20 on stock LTZ wheels 20x9 (+31) to 295/65/18 on Fuel Trophy 18x9 (+1).
I had already completed a small nor-cal mod and pulled back the liners in the front after trimming the bumper brackets some. Now with the new wheels/tires I’m barely rubbing the liner on the drivers side front where the windshield washer fluid reservoir is. At least I’m not rubbing the sway bar anymore like the LTZ wheels/33’s.

I purchased a universal style square reservoir and am about to tackle installing it in the secondary battery tray. I’m moving the pump and sensors over to the new tank. The only downside is I’ll lose my rear washer but I never use it anyway. Has anyone here done this before?
I saw a thread on gmfs where a guy did it on his nnbs Silverado and it should be the same.

what did you do with yours? @Rocket Man

 

[JT 07LTZ]

Damn no one has had issues with how close it sits to the fender liner?

I've seen it mentioned a couple times. Don't remember what guys were doing, though. Maybe heat gun and massage?

As HiHoe suggests, if the rub is only with the fender liner, and not with the washer reservoir itself (through the fender liner) or any other solid part, you can try using a heat gun and re-shape the fender liner to a position that eliminates the rub. Or you can make a pair of small slits in the fender liner at the point of the rub and insert a zip tie through the fender liner and anchor the zip tie to something solid and 'pull' the fender liner back from the tire.

In my case for my tire size, I had no rubs, but the edge of the tire came very, very close to the fender liner at the front, near the bottom a few inches above the bottom of the liner, when turning the tire from the steering wheel. I purchased some plastic push pins, the same as the ones that already exist at the front bottom of the fender liner. While holding the fender liner back away from the tire, I drilled a few new holes through the fender liner and the lower plastic backing, and then inserted the plastic push pins into the new holes. This had the effect of slightly re-shaping the curve of the fender liner at the front where the tire clearance was low, and it bought me an additional 1/4+ inch of clearance, which was more than enough for me.

I'll have to address mine and my current plan of action is to soften it with a heat gun and reshape it. I don't need much but I've also just looked at it from the fenders so I'm not sure it's even gonna work. If not, I may dig the salvage yards for a smaller one from another SUV with front and rear washers. I'll try to keep it GM for ease of retrofitting. Maybe look for one from a midsize or even compact SUV.

 

[JT 07LTZ]

I tried loosening the screws this weekend and warming it with a heat gun to try to reshape it back some. It wouldn’t move as much as I’d like it to. I think I’m going to have to just replace it. I’m not rubbing it in normal driving right now but on tight turns I’m hitting it through the wheel well.
Chevy really messed us up with these square wheel wells and putting that washer right there.

 

[bigdog9191999]

have 285/70/17 on our 03 denali and have very very little rub. I will probably secure part of the issue and heat gun the other part.

 

[Mighty Hd]

I’m having the same problem with factory wheels and 2 inch wide spacers on 285s. I don’t see why you can’t use a heat gun to heat up the plastic tank and slightly remodeled it. That’s what I did with the wheel liner

 

[Tozan]

I am running 35's on mine I have had no problem until I increased my wheel travel to 9+ inches a few weeks ago. Now it is hitting a little... I will probably look at it soon to determine what I will need to do.. I will post up my solution.

In my Silverado I used an ON3 Performance turbo mustang washer fluid relocation tank. just need to modify the wire harness and find a spot to mount it. I've been using it for a few years without any issues. https://www.on3performance.com/shop/on-3-performance-aluminum-windshield-washer-reservoir-w-pump/

Oh man I like this way better than the universal plastic reservoir I bought. I’m going to order one. Thanks!

On a different note, I’d give my left nut for one of On3’s twin turbo kits. 700 hp would be fun in a Tahoe

I'm really looking for a replacement tank too! did you find anything? Ideally, I don't want to have to mess with any wiring, i'd like it to be plug and play. Also, not really wanting to lose my battery tray (may want to add another batt at some point)
I did read where someone went to the junk yard and used one from (I think) a Crowne Vic??

Actually, I kind of wonder if any chevy smaller truck tank would be plug and play, like out of a blazer or something.. I found this:https://www.silveradosierra.com/exterior/washer-bottle-relocation-t419881.html

 

[Rocket Man]

what did you do with yours? @Rocket Man

Mine has the washer fluid delete mod at the moment. I have considered using a universal one but space in my engine bay is limited. Now that I’m on extended break, I might have to look into it again!

 

[Rocket Man]

I looked at my engine bay, looked at options, and decided the On3 reservoir made sense for me. It fits in my limited space, it’s not ugly, and it includes a pump. At first I thought $75 was a bit much but that’s about what a new OEM plastic one with pump would cost. It’s ordered. Thanks for helping me spend money @Dantheman1540. It will be nice to have washer fluid.

Nice glad I could help! post pics when you have it installed I need to find a new spot for mine.

I’m putting it to the left of the radiator but the engine bay on my Silverado has tubs that take up a lot of room. The fuse box, battery, and coolant overflow tank are all relocated.

 

[Dantheman1540]

That's exactly where mine was and I had no issues with it. I guess I just like moving and complicating things.

 

[Rocket Man]

I got it installed today. Super easy. I just lengthened the OEM wires (2 wires) added connectors and ran a new 1/8” hose.
