    Cheap, quick, easy Throttle Body gasket bypass/fix

    Well, at my Auto-X Sunday, my TB gasket gave out (It is for the coolant that heats it up and helps with winter and emissions). I puked some coolant on the grid and we had to leave. I had this "repair kit" on me, but me and my friend who co-drove my car with me both had obligations with work and a meeting respectfully, so we just drove home. The leaking stopped, and the temp didn't rise, and looking at the level in the reserve, we didn't lose that much really.

    Anyway, I did this same repair on MattE30's car after he came down to Purdue after driving from Chicago with it leaking. Doing his was harder because a) the coolant was hot b) we unhooked the breather hose and we didn't need to and putting it back on was a pain


    Here are the steps with pictures. This entire job, with pictures, and lending my PB Blaster to my roommate doing his alternator next to me took 25 minutes!! That's it!


    Costs under $6. I think I remember $3 for some reason, but I forget.


    There is a T-fitting with 1/2" radiator hose ends (perfect) and a cap that makes it a connector to bypass the gasket.


    As mentioned, class still on window, helmet in car. AND LOOK AT MY SEXY SHIRT FROM TRAK CLOTHING!

    Tools:
    Prestone Flush and Fill kit
    Flathead Screwdriver
    ...
    and also:
    8mm socket
    Rachet
    Distilled water
    Zip-ties (optional)
    Paper towel



    Unhook ICV. Loosen clamps. Rotate out of the way.



    Loosen hose clamps. And pull hoses off.


    Slide/force hoses onto T-fitting.


    With the part that the clamps were on past the fat part of the T-fitting, replace clamps and tighten.


    Zip-tie UNDER the ICV mount


    Re-install ICV and reconnect. And re-tighten clamps.


    Drive around and have the system heat up. Bleed system at Thermostat by the bolt on top, following Bentley instructions or whatever. Put some distilled water in.

    As mentioned, I didn't lose that much coolant at the Auto-X, and just a little doing the job as it is so high were the work is being done and the engine was ice cold:

    I've found the awesome $1.25 gasket from the dealer does wonders too


    Nice pink DSP, it matches your car. ;)

      too true... just make sure you tighten the screws down even like, do it twice just to make sure theyre all on right...

        I have one of those too. And a spare TB to make the process easier, but this is a ton easier and less messy, and less time consuming. (Not to mention I don't want to do that inbetween class and studying so I can drive home and get my other car, but I managed this today easy)

        And I don't drive my car in winter nor have emissions, so the feature isn't very worthwhile to me. I'd still recommend people in cold areas to keep the feature. I have a spare TB and gasket to sell if anyone doesn't want to take the cheap, easy, quick slacker approach. But this could definitely help someone who runs into the problem and needs a solution right then.

        thanks.

          Honestly Robert, my concern is not the ease of the fix... its the bypass mechanism.

          Coolant system under pressure at hot HPDE (not Auto-X)... flowing through a cheap little plastic T-valve with screw cap?? No thank you. Keeping the coolant in the car, and not under my rear wheels is more important.

            The plastic is thick and there is always loctite for the cap.

              Halfassed repair.
              You know it.
              I know it.

              Keep that in mind next time you jump down someones throat for not "doing it right"

                  So I should trust the plastic radiator screw drain plug, but not a thick plastic T-valve?

                            If it's possible to say something has been correctly half-assed, then that's what you've done.

                            One of the cleaner hose bypasses R3V members have admitted to.

                            Still wouldn't be surprised if it burst the next time you ran your car really hard though. At least you're prepared to do it right if you need to do it all over again.

                              Even though they are cheap for some it's one of those gaskets you usually have to special order or order online so if you need a quick fix to tide you over this looks like a good idea.
