Motorcraft RS76 Radiator Cap

OEM and works great!

I replaced my radiator with a Motorcraft radiator and discovered that I needed a new radiator cap. My old one was frayed around the perimeter and needed to be replaced. This is a very good product.

I bought this to replace a brand new motorad cap that I suspected of not opening when it was supposed to. My suspicions we're confirmed after the first heat cycle, when the coolant in the overflow tank was no longer a pretty green. Instead it was the same color as what is in the radiator. Amazing how quickly coolant changes color when it's run through an old cast iron block that was neglected for years.

Works fine on my 1995 Ford Windstar GL 3.8L V6

Good fit for my 1999 Ford Ranger 3.0L V6, even though there's not a specific Motorcraft part listed as an OEM replacement. This item was much better made than the generic cap that was on before. The fit is tight and the cap is much more difficult to remove. I have not noticed excess bubbling in the overflow tank after installing this cap. This is roughly 30% more expensive than the generic Stant or Motorad but is well worth it given the overall low cost.
