WTF??? | Ford EcoBoost Engines Now Have EGR Coolers Well this is a new one. We recently had a 2019 Ford Ranger FX4 in for testing. For those unfamiliar with the specs of Ford's reborn small'ish truck, it is currently only available with a 2.3L EcoBoost 4-Cylinder engine and the 10R80 10-Speed Auto. That mill has proven to be pretty stout in tuned Mustang application dating back to 2015, and there are a few guys turning them up in Rangers too. However, as I was poking around under the hood of our test truck I noticed something odd. Ford is equipping the Ranger's 2.3L with an Exhaust Gas Recirculation ("EGR") system that also includes a tiny EGR Cooler. By now you probably know that clogged EGR Coolers have led to the early death of countless diesels over the years, and I've never seen one fitted to a Ford gas motor. Nonetheless, there it sits. I thought technology had progressed passed the need for EGR on gas motors in general. It appears I was wrong, and 'diesel like' emissions systems are now being fitted to gas motors. Let's hope we don't start seeing Gasoline Particulate Filters ("GPFs") next: Since the 2.3L EB lacks a traditional exhaust manifold, the cooler connects directly to a post in the head. It's not nearly as big as the EGR Coolers we see on larger diesels, but the construction is similar to those found on 6.0 and 6.4 Powerstrokes.
