Chrysler 3.0 L EcoDiesel V6 Engine

VM Motori (a subsidiary of FCA) in Cento, Italy, produces the 3.0 EcoDiesel, a 3.0-litre V6 diesel engine.

In 2011, Fiat and Chrysler introduced the engine as an option for their European-market automobiles (codenamed as the A630 DOHC).


In 2014, the Ram 1500 and Jeep Grand Cherokee received the L630 DOHC variant, which Chrysler marketed as the EcoDiesel for the North American market.

Specifically, the L630 model satisfies North American Free Trade Agreement requirements (the emission norms of the North American market).

Chrysler 3.0 L EcoDiesel V6 Engine Problems & Reliability

There have been numerous concerns concerning the dependability of VM Motori engines in the past.


The Italian manufacturer may have made great strides in this area in recent years, but the 3.0 EcoDiesel engine still has issues and shortcomings in its design.

Customers are often upset and irritated with EcoDiesel because of the most common oil cooler failure. The oil cooler in this engine is cooled by water.

An engine coolant keeps the engine oil cooler. When the oil temperature in the engine rises to unsafe levels, usually while towing or pulling big loads, the oil cooler fails and allows hot engine oil to leak into the cooling system.

The efficiency of the cooling system may be diminished because oil has coated everything inside the radiator and the cooling pipes. Oil in the coolant expansion tank is an obvious indication of a problem.

The oil check valve is included in the housing adapter that houses the oil filter and cooler for the engine. Plastic and tiny, flimsy springs make this check valve a dud.

These springs deteriorate, and the check valve can fail after relatively lengthy runs at high oil temperatures.

The low oil pressure warning light on the dashboard may flash briefly at this point. During these flashes, the engine is operating without oil, which will quickly wreak havoc on its internal workings.

Failure of the exhaust gas recirculation (EGR) cooler, camshaft gear slippage, and connecting rod/main bearing failure in engines with short mileage can all be traced back to shoddy quality control on the production line.

Additionally, emissions defeat devices were discovered in 3.0 EcoDiesel engines in automobiles from model years 2014–2016.

More than 100,000 non-compliant vehicles were recalled by FCA in 2019 so that a software update could bring their emissions in line with regulations set by the U.S.

Environmental Protection Agency and the California Air Resource Board (CARB). The settlement was worth more than $300 million.

Chrysler 3.0 L EcoDiesel V6 Engine FAQ 

Are 3.0 EcoDiesel a good engine?

Some vehicles’ EcoDiesel engines have been driven up to 300,000 kilometres!

That’s a lot further than you’d get with a gas-powered engine, even the kind that’s designed to go at least 100,000 miles and can go up to 200,000 miles with the right maintenance.

It could add up to an extra 50% of driving time.

Who makes the Ram 3.0 L EcoDiesel V6 engine?

VM Motori, a Fiat Group Automobiles company based in Cento, Italy, produces the 3.0-litre EcoDiesel engine. Since 1992, the Chrysler Group has relied on diesel engines from VM Motori.

What are the issues with the 3.0 EcoDiesel?

In summary, common issues with Ram ecodiesel engines include a broken EGR cooler, a dripping oil cooler, a timing chain problem, and an inability to start the engine.

Inadequate emissions, connecting rods, camshaft gear slippage, bearing malfunction, and low mileage are a few more minor issues.

Is the 3.0 EcoDiesel a Cummins?

The Ram 1500 EcoDiesel, in fact, has a motor from a different manufacturer. Despite popular belief, Ram’s 3.0L turbodiesel engine isn’t made by Cummins.
