1997 K2500 - Washer Fluid Reservoir leak

I tried today to remove the washer fluid reservoir and it didn't seem to want to come out so I left it. I removed the drivers side battery tray and then the visible 2 top bolts holding the reservoir (one on neck and one into left side of body) but the reservoir only wanted to come up an inch or so. Rather than breaking something I left it. Can someone please pass along the secret to pulling that reservoir out and/or what is holding it? It is leaking. Motor still in bottom? Thanks in advance!

If it's like wifey's '99 burb there's a bolt accessed from the grill side.I had to work on the motors(one for the windshield & one for the rear hatch)to get 'em working again.The grill needs to come off for easier access.

Thanks Gary. This is the front reservoir.

 

I left the unused drivers side battery tray out so I could get to the reservoir easy when I learn the secret to getting it out, but the grille, uuch... :) On the next day with decent weather I'll see if I can find a front bolt. It didn't feel like there was a front bolt as the reservoir came up easily about an inch or so but then it would catch and didn't want to come up any more. I tried different angles as I was pulling up but no luck. Thanks again and I'll look to the front.

Yeah,I suppose if there was a bolt in the front the reservoir wouldn't have moved at all :dunno:

 

On wifey's '99 there's only one reservoir,maybe it's different than a '97.There are two motors,the rear hatch has a soft plastic tube running to it from the reservoir.The tube was kinked and not shooting water on the hatch window.I shortened & re-routed it at the window wiper control box.

 

After looking at ALLDATA it looks like that front bolt was probably for the battery tray.

I was looking at a parts explosion in a LMC truck catalog and the diagram shows a "grommit - mount" that receives a nipple on one of the bottom surfaces of the reservoir. That's the only thing they show that I didn't unhook. Sound familiar on yours?

Honestly I don't remember.I looked at LMC's site(page 105)and saw what you are talking about.Wife says her windshield washer isn't squirting so I'll be taking it apart again.This time I'll take pics :thumbs:

 

Hopefully you can wait 'til sat.

Much appreciated Gary. Its way too cold here for me to do anything before the weekend. :happysad:

 

On this one I'm not even sure where the pump is. On the older ones I used to work on I think I remember the pump being in the bottom of the reservoirs, but I couldn't tell from the LMC explosion just where the pump was on this one since there were three different jars shown with one pump sorta in the middle.

This is what I'm dealing with when pulling the reservoir,fun :lol:

A closer look,notice the two black plastic tubes side by side.They are the tubes going the the pumps,located between the reservoir and the radiator support and mounted to the reservoir.

I use a Ryobi impact drill when doing repairs like this,very strong and fast,makes it much easier.A couple of extensions & a 10mm socket and a 1/4'' socket adapter(for the drill) as well.

Reservoir #10 is what's on my burb(a '95 & OBDI),#14 is what's on both yours & my wife's('99).The pumps are tucked into a little pocket on the front bottom of the reservoir.The lower pic of the rear hatch is wrong for my wife's pump,it's not at the rear it's in the front attached to the reservoir.

More info Marty.....

 

After taking a few things out of the way I was able to remove the reservoir(with some fannagling & lifting,it still had a bunch of water in it and was heavy).After giving it a good look I saw the 1/2 to 3/4 nipple that sets in the grommet,however mine had no grommet,only a hole in a thin metal frame.

Thanks Gary, that's great that you got it out! And great pics!

 

Ok, so I'm guessing the nipple/grommet must be the only thing holding mine in place which makes sense since mine can be moved about sorta signifying it's being held in at one point only. And the grommet mount seems at about the right location where I could semi-rotate the jar. Maybe mine still has the rubber grommet that has gotten hard and stuck over the years. Mine looks identical to yours.

 

It's still too cold here to work on mine outside, but they're predicting a warm up in a few days so I'll jump on it as soon as I can and report back. When I was pulling up & around on mine it felt like it had quite a bit of water still in it, but it has stopped leaking, so I'm figuring it either has a crack up on the jar or maybe leaking at the pump. Did you remove one of your pumps? Does it just pull out of a rubber grommet?

 

Many thanks for the great pics!

I had the pumps out but don't remember how they came out.I think they just popped out.

Hi Gary, I finally got a day today with sun shining and over 50 degrees so I worked on the reservoir jar again and after working with it for a few minutes I decided to leave it for my friend at Chevy. It is working fine and it has quit leaking. I can tell when I pick up the jar a little that it still has quite a bit of fluid in it, so evidently there is a crack up on the jar, but the pump still works ok and the jar can still hold a good bit of fluid.

 

When I removed the bolt from jar to left side of body and the small bolt from neck to forward bulkhead, the jar still will not come up more than half to three quarters of an inch. It feels like it is hitting something positive and solid. From the drawing it seems like the grommet is free now. My suspicion is that it may be attached to the bulkhead that holds the evap canister. In your pic there is a vertical slot on a jar flap and I wonder if that could be my problem. Its the only other thing I can figure. I look forward to hearing what my friend at Chevy says. Its hard for me to believe getting a washer reservoir out could be such a problem, ha ha.. Anyway, its working for now and I'll report back when I find out exactly what's holding it. Many thanks!

I have the same problem right now but I think I know what's causing it, if you see in the picture with the red circle to the left of it there should be two screws sticking out that are behind the grill but you only see one in the picture they are keeping my reservoir from coming off they are too far out and they are exactly in the two circle indentations of the reservoir that's why it moves a few inches but is still stuck!

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
