What happens if EGR cooler fails?

When EGR cooler starts to fail, it will drain a lot of coolant out of the EGR cooler into your exhaust system. When that happens, the exhaust goes thru and interacts with that coolant and turns it into steam then come out in a form of white smoke out of the back of your exhaust system.

How do you know if your EGR cooler is bad?

Symptoms Of A Failing EGR Cooler Losing coolant. Steam or white smoke being emitted from the exhaust. High engine temperature. Sticking VGT Turbo Actuator.

Can you drive with a bad EGR cooler?

Can I drive with a bad EGR valve? Technically, you can drive your vehicle with a bad EGR valve, but your vehicle will run rough, shake at idle, and a check engine light will be illuminated. You might also hear popping sounds while driving down the road.

What does the EGR cooler do?

An EGR cooler works to improve a vehicle’s overall performance by cooling the exhaust gas before it’s recirculated into the intake manifold. This has the benefit of reducing the combustion temperature, thereby preventing valve clatter and detonation.

How much does it cost to replace EGR cooler?

To have it replaced, you will pay anywhere from $650 to nearly $1600. The average price is closer to $1,100, but what you pay will depend on the car you have and how much the parts and labor cost for that car. On average, the labor will run you about $440, but it could be a few hundred dollars more.

How long does an EGR cooler last?

The EGR cooler is an integral part of your vehicle that ensures your engine runs efficiently, and that you’re doing your part and not releasing as much noxious exhaust. Typically you can expect to get about 80,000 miles out of the part, but defects and damage may cause its lifespan to be shortened.

Should I delete my EGR cooler?

Installing an EGR delete kit reduces costs on repairs and fuel costs, as well as decreases soot deposits that an EGR valve produces. Disabling it prevents harmful contaminants from being reintroduced back into the engine, resulting in problems. When the engine’s performance increases, so does the fuel economy.

How long should an EGR cooler last?

How long does it take to change EGR cooler?

How long does an EGR valve replacement take? Looking once again at the averages delivered by our data, an EGR valve replacement should take around 3/4 of an hour.

Can EGR leak coolant?

The most frequent cause of failure is a leak originating from the exhaust-gas side. If the EGR cooler is positioned higher than the intake and exhaust valves, this can cause coolant to accumulate in the combustion chamber of one or more cylinders.

Can an EGR cooler be cleaned?

That’s a reasonable idea; EGR coolers are like radiators, only they use water to cool hot exhaust gases, instead of air to lower the hot water’s temperature. That means they can be cleaned like a radiator.
