    Re: New Heated Washer Replacement AT-37GM

    OK, so I know we have been going back and forth about the hose size. I have a 2008 AWD and I just came back from the NAPA store. The counter clerk and I went out to the car and pulled the hoses off the heated wash unit. The coupler that fits perfectly is a 3/16". the 1/8" was too small and the 1/4" too big. After connecting the in/out hoses from the wash unit, I checked for leaks with the 3/16" one I used and there were none at all. So unless GM used different sized hoses on some cars, I would suggest getting a 3/16" coupler. The NAPA part number is 9864, "straight connector." Cost is $3.29. Hope this helps. BTW, I pulled the 60 amp fuse without disconnecting the battery (with the engine off) and there were no problems. Whether that was correct or not, I don't know but I can say there were no problems on my car doing it that way.

    Now I am ready to take it into the dealer, get the unit removed and install the new one I am gong to order from Alpha Therm.

    Re: New Heated Washer Replacement AT-37GM

    I just came back from the dealer performing the recall. The dealer did not wrap the switch cables with electrical tape which annoyed me. Also the power connector was done differently than the TSB - did not wrap wires in electrical tape and just ripped the wires out of the connectors on the unit end which left the end somewhat exposed to moisture.

    In any event, I did not pre-connect the hoses bypassing the old unit ahead of time and left it to them to do their thing (I did remove the fuse to save the $5 on a fuse). To do the install, I did not need any additional couplers or hose connectors. Everything I needed came with the AT-37GM package. Took me 10 minutes.

    Re: New Heated Washer Replacement AT-37GM

    Got the recall done and of course GM removed all the hoses and connected the plastic hoses together with the plastic connector. I undid the connector(just squeeze on the connector and the hoses come apart. Now I need to pull off the male/female ends of the connector in order to connect the AlphaTherm hoses provided using the barb adapter also supplied - into the input and output ends of the main plastic hose. I will upload a pic once I get it off my phone. I spoke with AlphaTherm and he had a sample plastic connector with him and was able to pull each piece off the ends of the main hose.
    Anyone else do the hose install this way?

    Here is pic of plastic connector for the main hose. I need to pull off each end(male/female) leaving the small rubber hose that attaches to main hose.

    Re: New Heated Washer Replacement AT-37GM

    Im guessing the original setup had the hoses coming from the heater to these 2 connectors with similar male/female connectors. I should have noted how it all looked prior to recall. I couldnt find any clear picture of the connections in any GM literature. But AlphaTherms unit should come with instructions for dealing with this given their unit was designed for cars being recalled - and what I am left with is exactly what the recall work specifies doing with the hoses. I may have to wait till Monday and positively confirm with AlphaTherm what to do before I remove something(connectors) that may be needed.
    Unless someone else has dealt with this. I also may wind up trying to get some new hose(1/4 inch?) to connect up properly as the hoses from AlphaTherm appear smaller than original ones.

    Re: New Heated Washer Replacement AT-37GM

    I just installed mine yesterday. After the recall work was done, there were two rigid plastic hoses in the car connected by a section of about 12 inches of the flexible plastic hose. I just pulled one end of the flexible hose from the plastic connector to the rigid plastic one closest to the nozzles. It came right off. I connected the end that just came from the rigid plastic into the AT intake. It fit right in. Then I took one of the hoses that came with the AT unit and pulled the connector off. Cut it a little bit. Connected one end to the AT out (top one) and the other end to the rigid plastic hose that fed the nozzles. That was it. I did not compare to see size, but they all fit perfectly and I did not have any leaks at all.

    If you want me to, I can take pictures and post, but I am headed out of town right now, so I would have to wait until tomorrow.

    Re: New Heated Washer Replacement AT-37GM

    Pics would help thanks - sounds different than mine. Is there only the 1 plastic hose running up under the hood on your car? I seem to recall there was another hose but not sure. What I am wondering is - with the new AlphaTherm connected, every time you run the windshield washer, water will always run through the unit. If heated button is pressed, water will be heated, if just the washer on the stalk is used, water is NOT heated. Makes me think the original setup had a hose bypassing the unit when just running the windshield washer(not heated).

    I understand what you did - to confirm - if you look at the pic in my earlier message, you have the same thing but with a piece of flexible hose connecting the male and female ends of the plastic connector together(this connection was in the recall notice if additional length was needed.) In my case no additional length was needed so the plastic hose male/female ends were connected directly.

    You pulled out the flexble hose that was added in between the connectors from the female/open end and then re-connected this hose, now at the end of the input line from the water container, directly onto the input of the AT unit.
    Then, after removing the barb adapter from one of the supplied AT hoses, you connected the AT hose from the output of the AT unit into the female/open end of the wire connector going to the spray units.

    Correct?

    I tried pushing one of the AT hoses into the female connector and it does fit in snugly but I would probably tape in on with electrical tape so it wont come out for whatever reason.
    I also tried pushing one of tha AT hoses onto the male end of the input plastic connector and with a little soap it will go on OK.

    So it would appear I am good to go. I did previously try removing the plastic connector ends off of each section of wire hose and they dont appear to come off. I am not sure what AT support did when I spoke with them and they said they come right off. But in any event it appears I can leave these connectors on as they were.

    I cut off the connectors in your photo and put in barbed adapters to connect the small, rigid original tubing to the larger AlphaTherm supplied tubing which connects to the AT-37GM.

    Re: New Heated Washer Replacement AT-37GM

    Thanks for the info. I will finish up the install tomorrow. I watched the AT install video again and you see them disconnect the small plastic hose at the connectors we have been talking about, and there seems to be a hand jesture that these disconnected ends go into AT unit. It looks as if the connect one of their hoses to the male end and then on to the unit. For the other connection, they either removed the female connector or had additional hose already in the female end and the connected it to the unit.

    Re: New Heated Washer Replacement AT-37GM

    That plastic connector in the picture in the above post has barb connections at both ends. I pulled the hose going to the washer reservoir off this connector, leaving the connector with barb on the nozzle side hose, and leaving the soft rubber short section attached to the hard tubing going to the washer reservoir tubing. I then connected a section of the supplied hose, without any barb connectors on it, from the output of the AT-37GM to barbs on the connector connected to the nozzle side hose. I then used a section of the supplied hose, with the supplied barb connector, and connected the input side of the AT-37GM to the short rubber hose connected to the hard tubing going to the washer reservoir. I did not have to buy any additional barb fittings. All fits good and tight with no leaks.

    Re: New Heated Washer Replacement AT-37GM

    I just did what 928s recommended. Pulled the OEM hoses off the AT unit, coupled them with a 3/16" coupler from NAPA and tomorrow I am taking my car in to have the unit removed. Should be able to just snap the electrical connections back on and then slide the hoses onto the AT unit. Will let you know tomorrow how it comes out. I ordered the AT unit last week using the web716 code and got the 10% discount.

    Re: New Heated Washer Replacement AT-37GM

    Started my install Sunday and completed it today. After hooking up At hoses to male/female connectors on the small plastic hose, there was a slight leak from the female connection. The hose barely fit on the male connector but did not leak. I re-confirmed with AT that these male/female connetors do in fact come out. You have to twist while pulling and they come off OK. Initially I pulled straight out and they didnt budge and you start to worry that they arent meant to come off. But they do. This leaves a short rubber sleave at the end of each small plastic hose. The AT hoses then connect easily using their supplied barb adapters. When the recall work was done, I had no extra section of rubber hose. The plastic hoses connected directly with the connectors. Hardest part of install besides deciding on connection options, was removing the larger electrical connector end. I was trying to pull the small piece on the end where GM wrapped it with tape. In fact the end that comes off is quite large and when I accidentally got it off I thought I broke it, but then confirmed that this connector terminal is not at all like the smaller one. All this stuff is easy once its done but when you arent sure how things come apart, it gets difficult for those less adept at these things.
    I am a software guy - I dont do hardware(yet). Thanks for all the help.
