This is the stock style heater supply hose which runs from the black metal heater supply tube to the heater core inlet on your 1994-95 5.0L V8 Mustang.
One one the most common sources of coolant leaks are your Mustang's radiator and heater hoses. These hoses allow coolant to enter and leave the radiator and heater core to both cool the engine, and to heat the interior of the vehicle. Over time these hoses can get hard and brittle and can crack or break. Give the hoses a feel. Hoses should not be excessively hard, brittle, soft, mushy, or swollen.
If they are, be sure to replace them as soon as you can with high quality replacement hoses from Latemodel Restoration Supply.
Everytime I have delt with LateModel, it seems to get better and better. I have had all positive experiences which is much more than i can say about Summit, or American Muscle. I like the mom and pop shop feel i get when i deal with LateModel. We had a family buisness turning wrenches and a huge part of our success was customer service. Specifically treating every single female as how we would want our sister of mother treated when going to a buisness. We were always more than fair, accommodating and made sure to make all of our customers leave with a smile. And it worked. 30 years later my brother is still in buisness. Yesterday, I got that same type of treatment by Ian. Thank you Ian, you really went above and beyond like this was your personal buisness. Late Model, you just def locked in another lifelong customer thanks to Ian. Semper Fi
