The Problem with the EGR Cooler on a Ford Ranger
The EGR (Exhaust Gas Recirculation) cooler in a Ford Ranger can experience several issues, leading to potential engine damage and increased emissions. Here are the key problems associated with the EGR cooler on a Ford Ranger:
1. Cooler Failure: The cooler for the EGR valve can fail, leading to the pumping of water into the motor and potential bending of the conrods under the force. Replacing the cooler may not always resolve the issue, as some replacements have failed within a few weeks.
2. Engine Damage: When the EGR cooler malfunctions, it can result in hot exhaust gas entering the cylinders, potentially causing engine damage and increased emissions.
3. Coolant Leakage: The EGR cooler may develop external coolant leakage, which can result in dripping under the car or build-up around the area.
4. Transmission or Engine Access: Replacing the EGR cooler may require the transmission to be moved or the engine to be lifted, making it a complex and labor-intensive task .
5. Coolant System Issues: The design of the coolant system for the EGR in some models may contribute to the problem, as the coolant for the EGR has to pass through the heater matrix inside the cabin, potentially causing the cooler to split.
6. Replacement Challenges: Replacing the EGR cooler is not a simple task, and it may require additional inspections and a very concise coolant-bleed procedure.
7. Testing for Leaks: A specialist workshop can conduct a test to check for leaks in the EGR assembly, involving pressurizing the EGR beyond its normal operating pressure and checking for leaks with a fluorescent light.
It’s important to address EGR cooler issues promptly to prevent further damage and ensure the vehicle operates efficiently while minimizing emissions. If you suspect a problem with the EGR cooler in your Ford Ranger, it’s advisable to seek professional diagnosis and repair.
I hope this information helps you understand the potential issues associated with the EGR cooler on a Ford Ranger. If you have any further questions or need additional assistance, feel free to ask!

How much does it cost to replace an EGR cooler?

A replacement EGR cooler can cost around $125 to $700, depending on factors like its brand, quantity, condition, inlet size, material, and outlet size. Labor may cost you an additional $400 to $600, depending on the rates in your area.

How do I know if I have a bad EGR cooler?

Because of the hot coolant interacting with the hot exhaust. And literally steam cleaning your EGR valve. If you have any three of those symptoms. It’s a strong indicator that you have a leaking EGR.

Can you drive without an EGR cooler?

The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn’t working quite right, more toxic gases will be released into the air. For this reason, we don’t recommend driving without a working EGR valve for too long.

What is the problem with the EGR on a Ford Ranger?

When your Ford Ranger EGR valve fails, the check engine warning light will usually illuminate on the dash and the vehicle may run rough. The engine may run lean or rich, depending on why the valve has failed.

What happens when your EGR cooler goes bad?

Symptoms of EGR cooler failure can include odd-looking exhaust emissions and engine overheating. These systems are commonly fitted on modern diesel engines and some gasoline engines. As diesel fuel produces more environmentally damaging emissions than petrol, EGR systems are important for effective pollution control.

What is the problem with the EGR cooler on a 2017 Ford Ranger?

The common fault is that the EGR cooler leaks coolant internally. This leaks coolant into the exhaust manifold. This can cause overheating and engine running issues and in major leaks head gasket failure has been seen as a direct result of the cooler failure.

What is the most common causes of EGR failure?

However, the single biggest cause of failure is the buildup of carbon particles from the exhaust gases along the EGR and intake system passages. Over time this will clog tubes, exhaust gas channels and eventually the valve’s plunger mechanism, causing it to either stick open or close.

What is the EGR cooler fault on a Ford Ranger?

Original units have been known to leak coolant either externally from around the flanged joints on either side of the cooler or internally, with coolant leaking into the engine’s intake system, pulled along by the recirculated exhaust gases. Both of these failures are cause for EGR cooler replacement.

Can I drive with a bad EGR cooler?

Can you drive with a bad EGR cooler? Yes…for a little while, the coolant going through the DPF will eventually cause it to be plugged and it will be an even more expensive repair.

Can you drive with a broken EGR cooler?

Can you drive with a bad EGR cooler? Yes…for a little while, the coolant going through the DPF will eventually cause it to be plugged and it will be an even more expensive repair.
