What happens when an EGR cooler fails?
Your EGR system is vital in reducing emissions, but it can also regulate internal engine air temperature. This prevents engine overheating, so it’s important to maintain. EGR cooler failure can compromise the integrity of your vehicle, leading to severe engine damage and possible impairment to other components.
Can EGR cooler cause turbo failure?
The EGR cooler is another part in the diesel EGR system meant to reduce NOx gas emissions. The results of this failure can damage a number of different EGR system components, including the VGT turbo. Most failures happen inside the EGR cooler, so it’s easy to miss until symptoms start to show up elsewhere.
Can a bad EGR cooler cause loss of power?
Loss of coolant from the cooling system: this could be causing an internal leak in the exhaust system that could result in poor engine performance, and even cause more costly repairs.
How do I test my EGR cooler?
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.
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.
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.
Why do EGR coolers crack?
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. After many cycles of heating up and cooling down, the thermal expansion/contraction causes the materials inside the EGR cooler to fatigue and fracture.
How often do EGR coolers fail?
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.
