    I just replaced my upper radiator hose, and have called about every auto parts store in town but cannot find the lower one. Are they the same nobody even seems to be showing one listed in their books. Im also starting to lose some antifreeze. It looks like it runs under the radiator to the other side of the car before it drips down. After driving for awhile or on the highway and stopping it starts smoking from under the hood so I assume it must be blowing back on the exhaust.Anybody?

    Dealer or salvage... they are discontinued/obsolete.

    EDIT: That is the big reason I swapped in a custom radiator; it uses a commonly available hose due to the different configuration.

    There is another number. Do a search here. I can't find my notes on it. You can get it at napa or other places.

    Yes, thank you a lot to this post, I thought I was never going to find a lower radiator hose to my 90 SHO. But that Napa 7311 was a near perfect fit.

    For some reason the 7311 I tried (95 MTX, subframe full forward) was a little too friendly with the front engine mount. I have not tried it now that I have a 2 core.

    Might have gotten a mis-molded one -

    I have an 93 ATX.

    1. Is napa #7311 the correct hose?

    2. Do both the 2nd gen ATX and MTX share the same lower radiator hose?

    1. Yes.

    2. "Technically" no, BUT, the 7311 hose fits both the MTX and ATX (and is not listed for either car, you have to specifically ask for that hose number at the counter; not by make/model). If needed you can trim the 7311 hose to fit a little better if you want to, but as long as there are no kinks and it's not squashed against the subframe you'll be OK.

    Anyone try the Gates 22735 lower rad hose on an MTX? In my experience the NAPA 7311 didn't work very well, seems better suited for the ATX from what I can recall.

    There are a couple of forum member references of years past that show the lower radiator hose is a NAPA NBH 9368 or a Gates 22735 for the MTX and NAPA NBH 7311 for the ATX.
