What does the EGR cooler do on a diesel engine?

The EGR cooler is the portion of this system used to reduce the temperature of the exhaust gas before being recirculated into the engine intake air. Why do EGR Cooler Fail?

Is it legal to delete an EGR cooler?

Beyond the legality of an EGR delete, there’s another important factor to consider. If your EGR cooler is failing, it could be because it’s not getting enough coolant. This can indicate a problem with your failing water pump or failed OEM Oil cooler.

What happens to the coolant when the EGR valve is closed?

Cooled when the coolant flow removes heat and the EGR valve is closed, and then heated and stressed as hot exhaust gases pass through. Each time it heats up, the metal inside the cooler grows and strains against the restraints of the unyielding metal shell, causing stress and strain.

What is an EGR cooler and what does it do?

An EGR cooler is simply a heat exchanger which exchanges heat from the exhaust air to the engine coolant. One portion of the EGR cooler has exhaust gases flowing through it (latest designs use tubes) while the other portion of the EGR cooler is flooded with engine coolant.

What happens if the gaskets on the EGR cooler fail?

If the EGR cooler gaskets fail, or the cooler gets damaged for any reason, it can cause an exhaust leak to develop. An exhaust leak may be heard as an audible hissing or tapping sound coming from the front of the vehicle. This will reduce the efficiency of the EGR system, and negatively affect engine performance. 3. Check Engine Light comes on

Is there a recall on the BMW EGR cooler?

What happens if an EGR cooler is left unattended?

This can cause the unit to overheat, at which point it will not be able to cool the exhaust gases, and the engine will overheat as a result. Engine overheating can lead to knock or ping from the engine, and even serious damage, if the issue is left unattended.

What causes engine to overheat when EGR valve is closed?

However, other really nasty problems occur when the EGR valve jams closed: without the cooling effect of the exhaust gases, the engine starts to overheat. Over time, this overheating causes the engine oil that feeds the turbocharger to break down. When the engine oil starts to break down, the bearings in the turbocharger fail.

What to do if you have a bad EGR valve?

The first thing you do is to locate your EGR valve. You can take a look at the manufacturer’s guide of your vehicle to help you with this. Then put on your vehicle’s engine and rev your engine to about 2000 rpm. Gently create access to your valve and place your hand on it.

How is an EGR cooler used in an engine?

The EGR cooler is a component used to lower the temperature of the exhaust gases that are recirculated by the EGR system. The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. An EGR cooler is a metal device that employs thin passages and fins to cool the exhaust gases.

Can a bad EGR cooler cause an engine to overheat?

If the EGR cooler has any issues that restrict the flow of exhaust gases through the cooler it can cause the engine to overheat. Over time, carbon can build up on the inside of the EGR cooler and restrict flow through the cooler.

Why is my EGR valve not working properly?

If there is a fault in the EGR system, it can cause the EGR not to function properly. Your vehicle’s EGR valve can be faulty due to the accumulation of carbon deposits in its internal surface, pitting, burnt valve, a damaged diaphragm for a vacuum-type EGR valve, or distortion of the valve seat. This problem can also have the following causes:

Can a blanked off EGR improve engine performance?

Of course its not. The EGR pumps warm used air back into the engine instead of cold clean air. If you were to blank of the EGR, it would continuously get cold air thus an improvement in performance. For people looking for the best performance upgrade (such as myself), a remap with a blanked off EGR will provide excellent results.

Where is the EGR valve on a diesel engine?

As a result, it drains the coolant in your exhaust system which brings us back to symptom 1 – white smoke. Gooey EGR valve. The best way to check if you have a bad EGR cooler is to pull your EGR valve; the EGR valve is located on top of the engine next to the engine oil filter.

Why does my check engine light come on when my EGR valve is stuck?

Whether the EGR valve is clogged, stuck open, or stuck closed, you’re going to get a check engine light. While the check engine light will usually point you straight to the EGR valve, it is possible that it might come on due to a symptom instead of a cause.

Are there any disadvantages to using an EGR valve?

There are some disadvantages of EGR as well such as loss in fuel economy, low performance and, in diesel-engine cars, the production of soot increases. However, modern engines use clever technologies for an efficient process, for example, new diesel engines now use EGR cooler which cools down the exhaust gasses by passing the coolant.

What causes black smoke from the EGR valve?

2. Black Smoke from Exhaust. If the EGR valve stays open at all times and the exhaust fumes are being fed to the engine constantly, the engine gets deprived of oxygen. With too much fuel burning and less oxygen, a black smoke gets produced and escapes from the exhaust pipe especially when the car is idle.

Why is the EGR system in my car so hot?

The EGR system recirculates exhaust gases back into the engine in order to decrease cylinder temperatures and NOx emissions. The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines.

What causes an exhaust leak in an EGR cooler?

2. Exhaust leak. Another issue of a problem with the EGR cooler is exhaust leaks. If the EGR cooler gaskets fail, or the cooler gets damaged for any reason, it can cause an exhaust leak to develop.

How does faulty EGR valve cause turbo failure?

The valve ensures the EGR system is disabled at idle, when it would otherwise lead to erratic idling, and at peak power, when adding exhaust gases would reduce power output. The EGR valve is likely to stick and become coked up on some applications. BTN Turbo warns that this can have a significant effect on turbocharger performance.

Why does a diesel engine need an EGR cooler?

The gas circulated by the EGR system can be considerably hot however, especially in vehicles equipped with diesel engines. For this reason many diesel engines are equipped with EGR coolers to lower the temperature of the exhaust gases before they enter the engine.

Which is better EGR delete or EGR cooler?

So while you do have a choice between an EGR delete and a bulletproof diesel EGR cooler, the smart choice is on the option that is reliable, cost-effective, good for the environment and doesn’t check engine light. That option is the bulletproof diesel engine EGR Cooler.

What happens when you close the EGR valve on a diesel?

In the worst case this problem may cause melted pistons and therefore engine failure. The valves in the cylinder head may also begin to stick due to being heavily coated with carbon. However, other really nasty problems occur when the EGR valve jams closed: without the cooling effect of the exhaust gases, the engine starts to overheat.

What causes a rough idle with an EGR valve?

Rough idle. One of the most common symptoms of a problem with the vehicle’s EGR valve is a rough idle. It is not uncommon for EGR valves to malfunction and become stuck in the open position. This can lead to exhaust gas recirculation to occur causing a rough idle even when the conditions are not desirable.

Can a bad EGR valve cause poor acceleration?

Answer: The EGR could be stuck open. If the engine is fed exhaust fumes continuously, this can overheat the valve, cause poor acceleration. Check the EGR system and see if a bad vacuum solenoid is keeping the valve opened. Check the control circuit as well.

What is the EGR code on a Ford F250?

There are three main parts of the F250’s EGR system. They are the EGR Valve, Differential Pressure Sensor, and the Actuator Solenoid. P0401 is a general code, which means that regardless of the year (1996+ anyway) and the model, it’ll have the same meaning regardless of which manufacturer built the vehicle (Ford F250 or not).

I have a 2003 6.0 which has the round EGR cooler. These coolers are far better than the later square coolers. Mine is not showing any signs of failing, and I am not having EGR related issues.

Why do I need to replace my EGR cooler?

In many cases, there is surrounding damage, such as corrosion from overheating, since damaged coolers can cause high engine temperatures. Once the mechanic has determined the scope of the problem and decides that the EGR cooler needs replacing, he will drain out the coolant.

How many hours does it take to make an EGR cooler?

How can I tell if my EGR cooler is bad?

The best way to check if you have a bad EGR cooler is to pull your EGR valve; the EGR valve is located on top of the engine next to the engine oil filter. If you pull that valve out, it should be full of a nice dry black charcoal carbon which is from the exhaust system. If you have a bad EGR cooler, you would find a black gooey mess in the valve.

What happens if the EGR valve solenoid fails?

Should that valve fail to open, it will not significantly reduce the possibility of cooler failure. The cooler itself remains in contact with hot gases and coolant continues to circulate through it. So the very conditions that lead to cooler failure remain in place.

What causes white smoke from a bad EGR cooler?

White smoke. 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. Missing coolant from your D gas/overflow bottle.
