EGR coolers

Maintenance and efficiency of the exhaust system with EGR coolers

In this section of our online catalog, we offer a technical range of spare parts for engine thermal management in heavy-duty vehicles. EGR coolers are key components designed to lower the temperature of recirculated gases before they return to the combustion chamber, optimizing the overall performance of the truck or industrial vehicle.

This category is aimed at professional workshops and fleet managers seeking to restore the original functionality of the anti-pollution system. We facilitate the purchase of the exact replacement part with specialized advice to ensure proper installation and avoid issues arising from mechanical incompatibilities.

Key aspects when choosing the replacement part

• OEM reference: Always verify the original part code to guarantee a perfect geometric and functional fit.
• Engine type: Confirm that the cooler is compatible with the engine code and brand of the heavy-duty vehicle.
• Euro standard: Ensure that the component complies with the emission standard (Euro 4, 5, or 6) approved for your vehicle.
• Structural integrity: Evaluate materials resistant to internal corrosion caused by exhaust gas condensation.
• Installation elements: Check whether the selected product requires additional gaskets to ensure proper sealing.

Frequently asked questions

What is the function of the cooler in the EGR system?

Its main objective is to reduce the temperature of exhaust gases before reintroducing them into the intake. By cooling these gases, combustion temperature is lowered, drastically reducing nitrogen oxide (NOx) generation and protecting the engine in the long term.

What signs indicate a failure in the EGR cooler?

The most common symptoms include unexplained coolant loss, dense white smoke from the exhaust (steam), or increased engine temperature. In some cases, it may also cause starting issues if coolant enters the cylinders.

How do I find the compatible reference for my truck?

The most reliable method is to check the serial number engraved on the faulty part. If you do not have it, you can use the vehicle’s technical sheet so that our team can provide professional assistance and locate the equivalent part in our catalog.

Is it necessary to replace the gaskets when changing the part?

Yes, it is essential. Old gaskets are usually deformed or deteriorated due to heat and pressure. Using new gaskets ensures a tight seal, preventing gas or coolant leaks that could compromise the repair.
