The heater core is located in a case under the dash and connected into the engine cooling system. Consisting of tubes and fins, this component carries the coolant and transfers heat to the passenger cabin. As the coolant circulates through the core, the blower motor blows air through the core, warming the interior. The most common causes for heater core replacement are leakage and clogging. If you have noticed that your heater performance is less than satisfactory your heater core may be plugged with scale and debris from the cooling system, indicated by a coolant return hose that is significantly cooler than the inlet hose. If you have wet carpet and slimy film on the windows accompanied by the somewhat sweet smell of anti-freeze, the heater core is leaking coolant.

If symptoms and testing proves that it should be replaced, choose this Spectra Premium heater core designed to meet or exceed manufacturer's specifications. Designed for exact fit in the vehicle's OE heater casing, this product is manufactured using state-of-the-art equipment to the highest quality standards and 100% leak tested. Fully brazed aluminum units are available for many applications for increased durability in the toughest of winter conditions.

Part Number:


Spectra Premium warrants its climate control products, new or remanufactured, to be free from defects in material and workmanship for a period determined in this warranty from the date of installation or date of purchase. The sole liability of Spectra Premium, under this warranty, is to replace or repair such climate control products following its return to Spectra Premium or Spectra Premium’s authorised dealers, together with the original invoice for the climate control product.

This warranty covers any climate control produc2ts furnished from Spectra Premium but does not include labour of any kind or materials not furnished by Spectra Premium or any charge for any such labour or materials.

This warranty does not apply to any equipment which has been repaired or altered outside the factories of Spectra Premium Industries in any way so as, in the judgement of Spectra Premium to affect the stability of the product.

This warranty does not apply to products which have been subjected to misuse, negligence, and / or operating conditions in excess of those for which such equipment was designed and / or deemed defective by Spectra Premium as a result of the physical or chemical effects of water, steam or other liquids, gases or agents present in the system operating environment of the equipment or the failure of the vehicle warning system.

Warranty Coverage

  • Compressors for passenger cars and light duty vehicles are covered for a period of 1 year or 12,000 miles / 20,000 Km, whichever comes first, from the date of installation
  • Condensers are covered for a period of 2 years or 24,000 miles / 40,000 Km, whichever comes first, from the date of installation
  • Heater cores are covered for a period of 1 year or 12,000 miles / 20,000 Km, whichever comes first, from the date of installation
  • Evaporators are covered for a period of 1 year or 12,000 miles / 20,000 Km, whichever comes first, from the date of installation
  • Blower motors are covered for a period of 1 year or 12,000 miles / 20,000 Km, whichever comes first, from the date of installation
  • Equipment and service items are covered for a period of 120 days
  • Fluorescent and electronic leak detectors, electronic thermometers are covered for a period of 1 year from the date of purchase
  • All other Climate Control products are covered for a period of 120 days

The warranty for compressors will be denied if the following conditions are not followed (refer to compressor literature in box):

1. R-134a is the only approved refrigerant for all Spectra Premium compressors. Use of any other refrigerant will void the warranty.

2. The accumulator / filter drier must be replaced in conjunction with a compressor and/or condenser replacement.

3. The compressor clutch air gap must be verified prior to installation on the vehicle (refer to OEM specifications).

4. The specific and proper type of oil (see manufacturer’s specifications) should be inserted through the suction port of the compressor or oil plug. With the help of a spanner wrench turn the compressor shaft (not the clutch) 10 to15 times to help properly distribute the oil throughout the compressor and prevent hydraulic lockup.

5. The A/C system must be held under vacuum for a minimum of 45 minutes.

6. The fan clutch or radiator fan motor must be checked for proper operation.

7. For applications using an orifice tube or liquid line containing an orifice tube, the orifice tube must be replaced (installation of an orifice tube repair kit is also valid).

8. If the system has an expansion device (expansion valve) the technician must inspect and clean the filter screen or replace the valve if necessary.

9. The A/C system must be flushed with an approved flushing solvent. The only accepted option to flushing is the installation of an in-line filter or compressor suction screen (providing the refrigerant oil is not contaminated).

10. Condenser and radiator airflow must be cleared of any obstruction or restrictions. Clean and realign bent fins. The technician may need to replace the condenser in specific applications or situations (refer to compressor literature in box).

11. Spectra Premium requests that all parallel flow condensers be replaced when a compressor fails (the condenser design prevents a thorough cleaning and debris will cause system restrictions).

Replacement or repair of the climate control product by Spectra Premium shall be the only remedy available to a purchase under this warranty. Spectra Premium shall not be liable for any consequential or incidental damages of any kind resulting from the use or misuse of these or other products.

Magnuson-Moss Warranty Act:
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) Learn More
