How long should 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 do you know if your EGR cooler is bad?
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. If you have a bad EGR cooler, you would find a black gooey mess in the valve.
What happens when an EGR cooler fails?
This additional heat is simply dissipated through the radiator. However, since the EGR cooler connects the exhaust and cooling systems of your engine, failures inside the cooler may lead to coolant loss, overheating, and engine damage, among other failures.
Why do EGR coolers leak?
The EGR cooler can fail in 2 main ways -it can get blocked or it can develop a leak. Blockages will restrict the exhaust flow and also raise the intake temperature because the EGR cooler works like a radiator in reverse with heat from the exhaust gas flow being transferred to the engine coolant.
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.
Can you bypass EGR cooler?
Registered. You can sandwich a plate at the intake and exit of the EGR Cooler. No need to block of the EGR Tube as you will have a tune that effectively shuts off that path to the intake. This way no exhaust gases and no coolant will pass through the EGR Cooler.
Can you clean EGR cooler?
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. If the water runs clear, that’s as good a job your liquid cleaner is going to do.
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.
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’s the best way to clean an EGR cooler?
To clean really dirty passages, some repair shops place EGR coolers inside an ultrasonic cleaner. The ultrasonic waves vibrate the carbon loss while circulating detergent through the passages. This can speed up the cleaning process. How often should you clean your EGR’s cooler?
What does EGR stand for in diesel engine?
The term “EGR Cooler” has and will continue to become more popular in diesel repair shops in the United States and around the world. Many of you may be asking why this is or what does an EGR Cooler do. Let’s answer a few questions: What does “EGR” stand for? Exhaust Gas Recirculation. Why do most of the latest diesel engines have EGR Coolers?
