An automotive EGR cooler designed to lower exhaust gas temperatures and protect engine components. Drivers who need a durable, corrosion-resistant replacement for diesel emission control gain confidence from consistent thermal performance. Is the Lemark EGR Cooler the right choice for Opel and Vauxhall diesel models listed in the compatibility notes?
⚡ At a Glance
- • Cooling Performance: Efficient reduction of recirculated exhaust gas temperature, helping lower NOx and protect components
- • Best for: Owners of Opel Astra Estate (2010-2015) and Vauxhall Astra/Insignia models listed in compatibility notes
- • Not ideal for: Petrol engines or diesel vehicles not listed in the compatibility information, and repairs needing a included gasket
Robust aluminium construction with corrosion-resistant materials enables effective heat dissipation. Precision-engineered cooling channels promote uniform gas flow and reduce clogging risk.
Lower NOx emissions, with precision-engineered cooling channels
Internal channels are designed to promote uniform gas flow and maximise thermal transfer, reducing the temperature of recirculated exhaust gases. Corrosion-resistant materials help maintain flow efficiency over time.
Reduced exhaust temperatures support lower NOx output and help maintain exhaust-system performance under varied engine conditions.
Improved engine protection, with durable aluminium construction
A robust aluminium build resists corrosion and stands up to high thermal loads, helping to prevent heat-related damage to surrounding components. The cooler-only configuration focuses on thermal management without additional integrated parts.
Longer component life and fewer heat-related faults translate to greater reliability for diesel engines fitted within the listed vehicles.
Straightforward replacement, with clear vehicle compatibility
Compatibility covers specific Opel and Vauxhall Astra and Insignia estate, hatchback and saloon models across the provided year ranges. Technical notes indicate a cooler-only unit and that no gasket or seal is supplied.
Mechanics and DIYers can plan a direct cooler swap for the listed cars, while remembering to source the correct gasket or seal separately.
