Just have a good look out of the box and hit each cooling tube with a touch of break cleaner followed by a light jet of air as the one I had received contained a fair amount of preserving wax we call it Ensus fluid in Australia, you don't want to rely on your cooling system to resolve that. And take extra care with the O rings.

Fit like it should

Top Quality and Great Service!

Go ahead and do yourself a favor and replace everything in the system if you’re going to bother. I did the oil cooler, water pump, thermostat, around the alternator hose, and a coolant change to CAT ELC. Truck is running 9-12 degrees cooler at all times now. Couldnt be happier. Thanks to riff raff for offering affordable prices on genuine parts. I can’t afford to have this stuff fail so always going riff raff and genuine motor craft, Navistar etc.

Works like new again

Came in a Ford box, well packaged. Exactly what I needed to replace this 20 years old original.

Product was high-quality and ecactly as described. Came quickly and service couldnt have been better. I had a question during installation, called Riffraff and had help on the phone within 5 minutes.

Hands down cheapest price for oem direct fit I will recommend oem seal rings that riffraff offers it’s a tight snug fit don’t hit it with a Mallot to try and get them to pop together use a ratchet strap works perfectly in 3 clicks

Worked great. Just like it should. Make sure and grease all the o rings before pressing on the ends. Once you’ve done that, add more grease. Put grease inside the ends as well. It’s critical that the ends get pressed on evenly and it all stays square, otherwise you will shear your o ring on one of the internal passages.
