The EGR system in vehicles is designed to reduce emissions. The EGR cooler is the part of the system that cools down the exhaust before it reenters the engine, which reduces HC and CO emissions by preventing excessive heat-related oxidation during high-performance driving conditions. If your vehicle’s EGR cooler fails, you will experience a range of issues including poor fuel economy, rough idling, and false check engine lights.
Causes for EGR Cooler and Valve Failure
A failing EGR cooler can be caused by many different things. A leak in the cooler itself, clogged or damaged EGR valve, or a faulty coolant temperature sensor can all lead to poor performance of the EGR system. Whatever the cause, you’ll want to have an auto specialist take a look at your vehicle as soon as possible so that they can perform any necessary repairs before more extensive damage is done.
If you’ve noticed a drop in fuel economy, rough idling, or excessive smoke coming from your engine, it’s important that you bring your car to a certified technician right away. The sooner you bring your vehicle in for service, the less likely it is that more extensive engine damage will occur.
EGR coolers have a few different parts including the EGR valve and EGR cooler itself. Typically, when one of these components fails, there are other issues present that need to be addressed as well. If your car has an aftermarket performance intake or high-performance upgrade, this could put additional strain on the EGR system. I recommend having a certified technician perform any repairs on these types of vehicles to avoid additional damage that may occur.
When the EGR valves starts sticking, it can cause excessive smoke and poor engine performance. A clogged EGR cooler will also start emitting black smoke from your tailpipe. You’ll want to have your vehicle looked at by an auto specialist as soon as possible.
If your check engine light comes on, or if you experience rough idling, you’ll want to have your vehicle checked out right away by a certified technician. A faulty EGR cooler can cause many different engine problems including poor fuel economy, stalling, and misfires. You’ll want to have this problem diagnosed as soon as possible so that it can be repaired before further damage occurs.
A failing EGR cooler is not only going to cause issues with your car’s performance, but it will also affect the resale value of your vehicle. If you need EGR cooler repairs, be sure to take your car to an auto specialist for service. They will be able to diagnose any issues you’re experiencing and perform any necessary repairs at a reasonable price.
Factors to Consider When Buying Replacement EGR Valves and Coolers
If you’re in the market for replacement of an EGR valve or EGR cooler, you should take the following factors into account: price, durability and warranty. A low-cost replacement part is probably not going to last you very long or provide the same level of performance as a factory part. I recommend having an auto specialist perform any repairs on your vehicle so that they can install a high-quality aftermarket replacement part that will last for years to come.
The EGR valve and EGR cooler are both responsible for reducing emissions in your car’s engine. The EGR coolers themselves are usually located near the front of the engine block and are made up of metal or plastic components. The EGR valve itself is located in a manifold near the throttle body and is also made from metal or plastic. These two parts work together to reduce HC and CO emissions by cooling down hot exhaust before it enters the engine again.
There are many different things that can cause your vehicle’s check engine light to come on, including faulty sensors, clogged fuel injectors, misfiring spark plugs, broken belts and more. It’s important you address them as soon as possible so that you don’t get hit with a major repair bill.
I recommend having an auto specialist look at your vehicle whenever the check engine light comes on. They will be able to diagnose any issues and perform repairs at reasonable prices. If your car starts emitting excessive smoke from its tailpipe, it could indicate a problem with the EGR system. You’ll want to have this checked out right away by an auto specialist to avoid further damage to your engine.
An EGR cooler failure is going to cause poor engine performance and increased emissions. An EGR cooler that has failed will start leaking coolant, which can cause your car’s check engine light to come on. The first sign of a failing EGR valve is when it starts sticking, which can lead to rough idling and misfires in the engine.
If you’re looking for an aftermarket replacement part for your vehicle, I recommend having an auto specialist install it for you so that they can make sure it fits correctly. Many people choose to replace their EGR valve and cooler at the same time because they are both failing at the same time, but you don’t always have to do this.
