What are 3 types of EGR coolers?
EGR valve. EGR cooler (optional) EGR cooler bypass (optional) intake throttle valve.
How often should you replace the EGR cooler?
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.
What happens when EGR cooler fails?
But what happens if an EGR cooler fails? EGR cooler failure can compromise the integrity of your vehicle, leading to severe engine damage and possible impairment to other components. It can often go unnoticed for some time too as the symptoms are not always obvious.
How much does it cost to replace EGR cooler?
For a replacement EGR cooler you could be looking at between $270 and $3700, which will vary from case to case. The higher end pricing usually applies to modified or high performance engines, so for a passenger car you are likely looking at the lower end of the spectrum.
Can 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.
Is EGR cooler the same as EGR valve?
The cooler in your truck’s EGR system works with the EGR valve to create a mix of air, fuel, and exhaust gases that reduce emissions. These EGR coolers are a known weak point on most diesel engines, which leaves a lot of questions for owners.
Can you clean EGR cooler?
Can a EGR cooler be cleaned?
How long does it take to change EGR cooler?
Had mine done in about 2 1/2 hours.
Do you need an EGR cooler?
The EGR cooler keeps the temperature of exhaust gases in the EGR system low. These gases then get recirculated into the engine to decrease the temperatures of the cylinders. The gas circulated in the system can get extremely hot, which is what makes the EGR coolers so important.
Can you unclog an EGR cooler?
The best way to clean an EGR cooler is using ultrasonic cleaning technology offered by some radiator and other specialty repair shops around the country. It’s not that expensive, costing around $125, but not a service you’ll find in every town.
Can EGR cooler cause overheating?
Engine overheating: if coolant flow is restricted, the EGR cooler is unable to cool the exhaust gases. This not only allows NOx emissions to continue, it also causes overheating which can cause serious damage.
