Nissens heaters are designed, manufactured and tested to OE specifications. Nissens heater manufacturing and quality processes include a number of life tests, examined and tested by means of vibration, pressure impulse, thermal expansion, corrosion, and bursting to eliminate risk of leakage, insufficient heating performance or oil residues. Nissens heaters are thoroughly finished in every detail, fitting smoothly into the mounting cassette on HVAC module.
Features & Benefits:
  • Optimized airflow with extra foam as applicable
  • Strong mechanical stress resistance with high-quality plastics
  • High heating performance with special turbulators inside heater core for up to 15% higher heating performance
  • High thermal stress resistance with tank gaskets made from EPDM material
  • High resistance to bursts, shrinkage and extreme temperatures under normal operating conditions
  • Manufactured to OE standards in quality, performance and installation fit
Service Tip: If you are experiencing unexplained or reoccurring heater core leaks, or notice dark spots on your failed heater core, test your coolant for Electrolysis. If detected, correct the source of the problem before replacing your failed heater core to prevent repeat failure.
Cooling System Maintenance | Tips & Tools

Premature Heater Core failure is often caused by poor Cooling System maintenance. Protect your engine and maximize system performance with simple preventative maintenance:

  • Completely drain and flush the system using Cooling System Flush. Flushing the system is critical to prevent system contamination and failure.
  • Consider replacing the Heater Hoses (and Hose Clamps), Thermostat and Radiator Cap as part of routine preventative maintenance. Rust and debris from degrading parts can clog the Heater Core and Radiator, and lead to costly engine damage.
  • Refill Radiator with fresh Coolant / Antifreeze according to the volume and formula specified in your Owner's Manual. Inspect levels and condition every year.
