The radiator in the Factory Five Type 65 coupe is quite a distance from the engine when compared to other cars. The kit comes with an flexible metal pipe to be cut to fit. Since my plan was to use as many factory parts as possible, I sought to find Ford hoses that could be used with as little modifications as possible. Here is my solution.

The first thing that you have to think of when designing a cooling system is how will the system be filled? If you don't have the filler as the highest point in the system, then you might have problems getting rid of all the air that might be there when you fill it. I have seen many builders complain that they are having a hard time "burping" the cooling system, so this was a top priority.

The solution is a de-gas tank. This is a "purge" canister positioned at the highest point in the cooling system. This allows the coolant circuits to be filled more completely than a conventional system. The canister bleeds off the trapped vapors that tend to accumulate in a sealed system as a result of normal thermal cycling.



All Mustangs since 1996 have this type of system. So the first part in the Type 65 Coupe coolant system is a overflow de-gas tank from a 1996-2004 Mustang.



For a de-gas tank to work, it must be the highest part of the system. With the low hood of the coupe, this makes it very difficult to use the 1987-1993 Mustang upper coolant hose.



The 1987-1993 radiator hose (circled) runs on top of the alternator and would cause clearance problems with the hood. It would also prevent mounting the de-gas tank in a location that would make the filler cap the highest point in the system.

In 1994, when they redesigned the Mustang, they lowered the hood. This lowering caused Ford to use the accessory mounting brackets from the 1993 Thunderbird. It also caused them to redesign the upper radiator hose (circled) to go beside the alternator.



In my system, this lowered the hose so it would be below the de-gas tank. So this is the hose that I used.

The problem with using the 1993 Thunderbird, 1994-1995 Mustang accessory brackets is that they are not as common as others and can be more expensive to purchase along with all the unique hoses and connectors too.

There is another Ford vehicle that uses a similar routed hose and is common. The F-150. So for my design, I used these accessory brackets.





One of the things that was needed to complete the radiator hoses is some extensions. This is because the radiator is so far forward from the engine.

The "T" pipe is for the lower radiator hoses and the straight pipe is for the upper rad hoses.



Dimensions and drawings for the pipes.



UPPER RAD HOSES



* Part Numbers *
F4ZZ-8260-A (Motorcraft KM-2432)
F7ZZ-8260-BB (Motorcraft KM-3259)

The upper rad hoses consist of a 1994-1995 Mustang upper rad hose (KM-2432) which goes from the thermostat housing to the aluminum connector. The hose goes on with no modifications. A 1987-1993 Mustang upper rad hose (KM-3259) goes from the aluminum connector to the radiator inlet. KM-3259 needs to be cut as shown.



LOWER RAD HOSES









* Part Numbers *
F4ZZ-8286-A (Motorcraft KM-2831)

The lower rad hose consists of a 1994-1995 Mustang lower rad hose (KM-2831) which runs from the radiator outlet to the aluminum connector. This hose needs to be cut as shown.
