The complete EGR cooler replacement cost guide

Need a replacement EGR? Here are the costs

Have you noticed your EGR cooler hasn’t been up to scratch recently? Depending on the issue, the part may need to be replaced. If that’s the case, Natrad is here to help. We’ve collated an all-you-need-to-know guide to simplify the replacement process and give you an idea of what to expect financially.

An EGR cooler is an important part of the EGR (Exhaust Gas Recirculation) system and overall cooling system. Serious consequences can occur if it fails. Potential issues a bad EGR cooler can cause include:

  • increased emissions
  • reduced performance
  • severe engine damage

These issues can be mitigated if you act fast. It is important to diagnose the problem as early as possible.

Natrad has a range of quality EGR coolers suited to a wide variety of vehicles. If you think you might need your EGR cooler replaced, read on to find out out more about our EGR coolers and intercoolers.

Understanding the EGR Cooler’s Function

Before we discuss the cost of EGR cooler replacement, it’s crucial to grasp the role of this component in your vehicle. The EGR system recirculates a portion of exhaust gases back into the intake manifold, which reduces combustion temperature and minimises the formation of harmful nitrogen oxides. The EGR cooler specifically cools these recirculated exhaust gases, preventing overheating, which aids in maintaining optimal engine performance.

If your EGR valve fails, it can lead to several issues, affecting both engine performance and emissions control. This includes reduced fuel efficiency and increased engine heat. Therefore, it’s important to get an EGR cooler replacement when required.

What causes a Faulty EGR Cooler?

A faulty EGR system can arise from a variety of underlying causes, each of which can impact the system’s ability to effectively reduce harmful emissions and optimise engine performance.

Carbon buildup is a prevalent issue, as deposits accumulate over time within the EGR valve and cooler, obstructing the flow of exhaust gases. Clogged EGR valves, often hindered by carbon or debris, can disrupt the crucial process of recirculating gases into the intake exhaust manifold.

Vacuum leaks, which compromise the system’s necessary vacuum pressure, can also lead to EGR valve malfunctions. In modern EGR systems, electronic components and sensors can fail, affecting the system’s operation. A sticky EGR valve, coolant leaks in the EGR cooler, and poor maintenance practices can all contribute to additional EGR system faults.

EGR cooler replacement cost factors

So, you need a new EGR cooler but don’t know where to start? Let’s look at influencing factors on cost. There are several which impact replacement costs, including the part itself, labour, location, availability and vehicle type (just to name a few).

Part cost

For a replacement EGR cooler, you could be looking at prices between $270 and $4000+, varying widely case by case. The higher-end pricing usually applies to advanced or complex designed EGRs, those for large engines and heavy-duty vehicles. Passenger cars will typically have a lower price ranging between $270-$1500.

At Natrad, we have a wide range of quality EGR coolers available from workshops nationwide. To find out more about specific part replacement costs for your EGR cooler, enquire in-store and chat with our qualified team.


This factor depends entirely on what vehicle you have. Because engine bays are all built differently, ease of access (or the lack of it) to your EGR cooler will influence the cost of labour. To find out what figure you might be looking at, contact your nearest Natrad workshop and request a detailed quote.


Geography can also influence pricing, especially if parts are not readily available in your location. It’s best to ask your local store for better ideas on what to expect. As mentioned before, your closest Natrad workshop can provide a quote and discuss their accessibility of parts. This is especially important if you have a faulty EGR valve or require an EGR valve replacement.

Potential Damage

Another factor that may also influence cost is whether other parts have been damaged in the system. Damages to the EGR system are likely to occur due to:

  • thermal shock
  • electrolysis
  • coolant contamination

While these damages are not necessarily linked, they can nonetheless occur simultaneously (though this is somewhat rare). If multiple parts need to be repaired or replaced, there is likely going to be a higher cost for repairs.

If you are in need of multiple replacement parts, our Natrad technicians can guide you on the best choice for your vehicle.

How long does it take to replace an EGR cooler?

The time it takes to replace an Exhaust Gas Recirculation (EGR) cooler can vary depending on several factors, including the vehicle make & model, the complexity of the installation, the mechanic’s experience, and the specific circumstances of the job. In general, a straightforward EGR cooler replacement can take anywhere between 2-4 hours, but it may take longer in some cases.
