How-To: Replace Heated Washer Unit With The Alphatherm.

OK, just finished installing an Alphatherm AT37GM to get around the heated washer recall, and wanted to post a few notes to answer questions and save people a few minutes:

 

1) This install is cake, if you can change your oil, you can replace the heated washer part. Should take 1/2 hr or less.

 

2) The part looks EXACTLY like the old one. This made me a bit annoyed, as there is no way a tech could tell that I upgraded the unit. They could have added an extra bump in the plastic mold, or stamped the model number on the part more prominently. Now I have to make sure my GMC tech doesn't do the recall and pull my new part! Maybe a fluorescent sticker is needed....

 

3) IMHO: if the original problem occurred in something like 10 trucks out of 1.5 million, and with the better replacement unit lowering those odds, the problem is fixed in my book.

 

3) Installation notes:

 

  • Remove the corner brace to make life easier -- it's the only 4 bolts you need to remove to do the job
  • Before you put the brace back, grab the extra hose they provide in the kit, and attach it to the "out" nipple of the Alphatherm. Add washer fluid to the reservoir, and put the other end of the hose in the washer fluid bottle you just emptied. With the unit clipped onto the firewall, prime the unit, then push the button and test to make sure it's heating properly by feeling the fluid as it hits the inside of the bottle. The sounds stupid, but when it's 90+ degrees outside, there's no easy way to tell if the unit works by spraying the windshield. It's also real easy to switch the in/out hoses by mistake.

Again, these might sounds like common sense, but it takes 1 minute to read this and it might save someone 10 minutes of futzing.

Thanks for posting these helpful hints. It'll come in handy when I install the alphatherm unit....after GM does the recall on my truck.

Can you do this after the dealer recall?

Yes. The dealer will remove the old unit and throw it out. The wire harness in your truck isn't supposed to be touched.

Thus making the newer alphatherm unit 'plug and play'.

NICE! I am going this route as well. I need to get my rear speakers replaced, but putting it off b/c I dont want them taking my heated fluid!

Thanks, mine arrived yesterday and the truck is going in Monday for the seat covers and likely to have this done as well. I'll sticky this topic up top as it is pretty current and seems like a number of us are ordering the units to replace the old ones.

I just got my recall done at the Dealer. I told them I didn't want to get mine done. They said they had no choice (which is not true). They also told me that they had to send the unit back to GM. All the wires are still there. Now I just need to wait for the Black Bear tune in Buffalo to pick up my alphatherm unit from a member.

Installed today, SO Easy even a caveman could do it. In and out, 20 mins, just prime the pump with the regular washer fluid switch before trying to heat and youre good!

You guys better be careful doing this...

 

I've personally done about 40 of these recalls. After the recall is complete, NO heated washer system exists under the hood anymore.

 

So, what happens when you guys go in for service, and the Tech raises the hood?? The Tech WILL SEE your new heated wash systems, and there will be problems.

 

Doesn't matter if it was 10 of 15,000,000 trucks...the thing to remember is GM WASHES THEIR HANDS TOTALLY of this whole heated wash system stuff. The company that originally produced these units is out of business.

 

I wouldn't be surprised if some of you get threatened with rejected warranty/warranty items, especially if GM doesn't want heated wash systems anymore...

 

Just be very careful on what you install on these trucks...

So, if a tech sees the new pump while opening the hood to do warranty work on an unrelated system of the truck, the dealer will tell me that the new pump made the part go bad and void my warranty? I do believe that there is a law against that called the M......(cant remember full name) Act. Now, if the new pump catches on fire and burns up a bunch of stuff then I totally get it. But there is no way in hell that you are going to tell me that my tranny (for example) burned up because I added a heated washer unit to the truck.

I don't think there will be any problems. Obviously if the aftermarket part causes any problems, they won't be covered by warranty, but we all understand that. And once the warranty ends, who cares? People are modding their trucks all the time - this is no different.

You might be thinking of the Magnuson-Moss Warranty Act, which is intended to protect consumers from deceptive warranty practices. All it means is that the manufacturer has to be clear about what the warranty covers, and also they have to honor it.

GM has determined there was a defect in the heated wash system, causing vehicles to catch fire, and burn to the ground.

 

That's what this recall is all about.

 

And obviously, a heated wash system isn't going to cause a trans concern (dlewis)

 

Here's a scenario:

 

You get the recall done. Heated wash removed by GM Tech

 

You install "brand-x" heated wash system, on your own accord, and tell nobody.

 

3 days later your pickup burns to the ground. Investigators trace source of fire to "brand-x" wash system.

 

Who's fault is it?? Not GM's, that's for sure.

 

Get the picture??

I am waiting for the class action suit because $100 does not fully compensate for the loss. I am thinking in more the range of 10% of truck list price for each truck, plus attorney fees.

 

...and the settlement check will be @ $1.38 after class admin fees are taken.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

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

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      By Chuck FB · Posted

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.
