Lower Radiator Hose Discontinued? Who makes replacement?
1996-2003 Mustang GT 4.6L
Lower Radiator hose KM-4377
Ordered a set of radiator hoses from Rock Auto. Picture of the AC Delco Lower Radiator hose showed the stock style with the overmolded T junction. Open the box and it is three hoses crimped with plastic sleeves onto a plastic T. Looks weak. Went in search of stock style. Went to three part stores. In the computer at each store it was shown as the overmolded style but when brought out to look at them, they were the same three hose crimped together style. I figured, I'll just head to the local Ford parts dept. They look it up and tell me it has been discontinued by Motorcraft.
I found a few of the KM-4377 on ebay. But does anyone here know who makes an original style lower radiator hose with the full overmolding?
I might be a little paranoid but under high consistent loads and high temperatures at the track the plastic crimps to the plastic T worry me. I am sure they have been tested, yadda, yadda, yadda. But I still don't like it.
