You’re in the middle of a job when your semitruck starts flashing up a fault code. Your DTC scan tool says you have a faulty EGR cooler, and your mechanic says you need a new part! Should you accept the high price and potentially long wait for a new OEM part or risk an unknown aftermarket seller? But then you realize there’s a third option! You order a replacement Roadwarrior EGR cooler either online or through your dealer. Coming from a well-known aftermarket manufacturer with 13 North American warehouses, your new EGR cooler arrives much faster and costs much less than expected! You replace the part and get your semitruck’s EGR system up and running in no time.
What is an EGR Cooler and Why Do You Need One?
An EGR cooler is part of the exhaust gas recirculation (EGR) system. Hot exhaust gas leaves the engine through the exhaust manifold, travels to the EGR cooler and is cooled down before returning to the combustion chamber. However, if the EGR cooler fails, the heat of the returning exhaust can jam open the EGR valve, flooding the engine with exhaust. Diesel combustion chambers need exact temperatures to run smoothly, so this can cause misaligned compression, engine knock and piston damage. You can avoid these problems by replacing or repairing faulty EGR coolers and searching for underlying issues like blocked coolant lines!
Why are Roadwarrior EGR Coolers a Good Investment?
When it comes to the aftertreatment industry, we go out of our way to be a brand you can trust! Our ties to DCL International give us access to superior materials and the latest emissions control research, and our engineers use this to create products you can rely on! These benefits have helped us build the largest catalogue of aftermarket aftertreatment parts in the industry, and our selection is always growing.
In recent years, we’ve seen the problems semitruck drivers have had with EGR coolers and the difficulty of replacing them. We realized we could help OTR drivers by tackling these issues and producing reliable aftermarket EGR coolers! In the rare instance that one of our parts is faulty, our industry-leading record of honoring warranty claims means we can send a replacement part out in no time.
Major Benefits of EGR!
- Keep your truck emissions compliant!
Meet emissions regulations, reduce regens and take the pressure off your aftertreatment system by reducing the soot generated by idling.
- Improve your fuel economy!
Cut down fuel consumption by re-burning the soot-rich exhaust from low-duty cycles like idling and driving in heavy traffic.
- Protect your Engine!
The chilled exhaust from the EGR cooler helps control combustion temperatures. This is important because over-hot combustion can jam your EGR valve and damage the piston and crankshaft in your combustion chamber.
- Reduce Your Regens!
The EGR reduces soot build-up on the DPF by re-burning soot-heavy exhaust from the EGR cooler before it reaches the DPF. This means fewer inconvenient forced regens, because DPF regens are the truck’s way of removing accumulated soot, ash, and dirt.
Can EGR reduce engine power or fuel efficiency?
A properly functioning EGR won’t noticeably impact engine power and can improve fuel efficiency! The EGR valve is closed when you start the engine, accelerate, hit high speeds, climb steep hills, and pull extra-heavy loads. This means the cooled exhaust doesn’t enter the engine, it gets the pure oxygen. This allows the engine to reach higher combustion temperatures, burn more fuel and produce the extra power needed. The EGR valve begins to open in settings that require less power and generate excess soot, like driving in traffic and idling. This reduces combustion temperatures, saves fuel, and protects your aftertreatment system and engine from soot build-up!
Why do EGR coolers fail?
Soot from excessive idling can clog the lines, stopping the exhaust reaching the EGR cooler, and sometimes creating enough pressure to split the lines. The exhaust lines can also become clogged when oil leaks into the combustion chamber, forming an oil and soot sludge that escapes through the exhaust manifold!
Another common cause of EGR cooler failure is blocked oil coolant lines stopping coolant reaching the tank! Without coolant, the EGR cooler can’t function and hot gas returns to the engine, disrupting combustion and reducing fuel economy! The heat of the gas can also jam the EGR valve open, letting uncontrolled amounts of exhaust into the engine.
Are Roadwarrior EGR coolers covered by a warranty?
Yes, Roadwarrior products come with a hassle-free warranty that makes them easy to return if you have any problems! Our parts also come with permanent and easy-to-identify serial numbers. This allows us to have an industry-leading record of honoring claims!
Can EGR coolers handle the cold?
EGR coolers are usually located high up in the cooling system, and the exhaust lines pass through the coolant tank, so the cold shouldn’t be an issue. However, pressure build-up from blocked coolant lines can crack the EGR cooler or split the lines. If this happens, coolant may escape into the exhaust as boiling steam and leave the truck as white exhaust smoke!
Why is EGR delete a bad idea?
EGR is an emissions-control system that returns exhaust gas and partially burnt fuel to the engine at low speeds and during idle. This lowers soot levels in the exhaust, protecting the aftertreatment system and reducing regens! EGR delete means removing a system your engine relies on! Your semitruck also uses the cooled exhaust from the EGR cooler to control combustion temperatures. This stops the engine running too hot, improves fuel efficiency, and reduces the risk of engine knock and misaligned compression! As EGR is often a legal requirement, deleting yours can also lead to failed emissions tests, heavy fines and even losing your operating license!
