The 3.0 EcoDiesel's EGR cooler and oil cooler fail in the same window — it's the failure behind the 2019 recall and the 2025 settlement. We replace the EGR cooler, oil cooler and oil pump together, with a full flush, at your home.
The 3.0 EcoDiesel in the 2014–2019 Ram 1500 has a documented EGR cooler defect — the cooler cracks from thermal fatigue, seriously enough that it triggered a recall in 2019 and litigation that ran to a 2025 settlement. A cracked cooler leaks coolant where it doesn't belong, and on this engine the failure rarely travels alone.
The oil cooler fails in the same window, and that's where the signature symptom comes from: oil and coolant mixing, showing up as a latte-coloured emulsion in the coolant bottle. Mixed fluids are poison in both directions — oil contaminated with coolant loses its lubricating film, and the oil pump, working at the bottom of that compromised system, can end up starved or damaged. That's why the honest version of this repair includes the pump, not just the two coolers.
You'll often see P0299 (underboost) and P050D (cold start rough idle) along the way, plus white smoke and overheating as the cooling system loses capacity. Replacing one cooler at a time on this engine is a losing game — the fluids have already cross-contaminated the whole circuit. The complete job is both coolers, the oil pump, and a thorough flush of both systems so the new parts live in clean fluid.
If your Ram is doing any of these, this is the likely cause:
Oil and coolant mixing is one of the few problems that damages an engine while parked in your driveway — the emulsion sits in passages and bearings either way. Every kilometre driven on mixed fluids erodes bearing surfaces the oil can no longer protect, and an overheating event on top of it puts the head gasket and beyond into play. This failure has a settlement attached to it for a reason; it does not self-stabilize.
Yes — both coolers, the pump, and the flushes are engine-in-truck work. It's a long day at your driveway, and honestly that's the better place for it: the truck shouldn't really be driven on mixed fluids anyway, so repairing it where it sits beats a tow.
It's three components deep in the engine valley plus dual-system flushes — a lot of book hours at dealer rates, with each part at list price. We quote the complete package as one flat price before any work starts. And if your truck's history suggests recall or settlement coverage might apply, we'll tell you to check that first — we'd rather lose a job than have you pay for covered work.
The 2019 recall and the 2025 settlement covered specific failures on specific terms, and many trucks are now outside those bounds by time, kilometres, or claim windows. It's genuinely worth checking your VIN with a dealer first. If you're outside coverage — which is most of the trucks we see — this is the repair.
Because it's been pumping contaminated oil, and its internals wear in ways that don't show symptoms until it fails — and an oil pump failure on a fresh repair destroys everything you just paid for. With the system already open and drained, the pump is cheap insurance on an engine you're investing real money into.
