Important Notes for Heater Core Replacement
Please note that you may find a copper brass heater core instead of an
aluminum unit as appearing in our online e-catalogue. Both material types
are covered by Spectra Premium and have been tested and approved by our
team. They both satisfy fit and performance standards.
Read instructions completely before proceeding with repair.
Never remove the radiator cap when the engine is hot. Personal injuries may
occur from the hot coolant liquid under pressure found in the system.
1. After having removed the heater core, it is important to identify the
root cause of the failure.
2. If the heater core is aluminum check for electrolysis (see information
below).
3. Inspect radiator for leaks.
4. Inspect or replace pressure cap.
5. Inspect and replace all cracked or leaking heater and radiator hoses.
6. Inspect and replace damaged / corroded hose clamps.
7. Inspect all drive belts (especially for water pump).
8. Inspect cooling fan blades and operation.
9. Thoroughly flush and clean your cooling system. Refill with new
coolant, preferably with distilled water or premixed solutions. Failure
to do so will void the warranty.
10. Replace thermostat.
11. Bleeding the system (if necessary) is required on many models where
the radiator is mounted lower than the engine cooling passages.
When filling the system, air may stay trapped in the engine or
heater core and cause eventual damage or hard to solve symptoms.
Many models are equipped with bleeder screws located near the
thermostat housing. Refer to the procedures found in the owners
manual or repair manuals. Some vehicles need to have the front
end lifted high enough to make the air bubbles circulate back to the
radiator.
