Almost good for hoses

The hose arrived on time with no damage to the packaging. The hose is almost too long and I had to twist the fitting a few degrees to get rid of the kink.

Pros
  • Radiator
Cons
  • Nothing here

WILL NOT FIT 2.3T as listed

This does not fit my car (1980 Mustang 2.3T) as listed on the Revain shopping tool. The return period is of course over as it was a project car.

Pros
  • Cars
Cons
  • OK

Fits better than others

This hose has an end that is larger than the inside diameter. then others that I tried and slipped on easily. As others have said, you may need to cut off some pieces from one end. Fits my '87 Mustang 302 which is about 1" in diameter. the end. Some Fords have a larger diameter. hose end of the thermostat housing than the hose end of the water pump.

Pros

It felt like I was donating to charity

The hose needs to be trimmed about 1/2" on each side to keep it from bending or kinking. Rubber, although I didn't use excessive force to remove it. It was a waste of money, it started falling apart even before I had a chance to put the yoke on it.

Pros
  • Replacement parts
Cons
  • Obsolete model
