Cons

  • smaller than oem

Best Uses

    Comments about CARQUEST Heater Core:

    This unit does have many more fins than the original copper type core. Be aware though, that it is smaller than the heater core that I replaced in my '76 Chevy pickup. and you may need to adjust for the difference in the way it bolts to your box or you will be frustrated about lining up the box to the holes in your firewall. Since you pretty much have to stand on your head to do this job, it helps to get that adjustment as close as possible, since your probably going to get a headache anyway.

          is it hard to replace a heater core in a 1982 chevy c30 pickup. I am not an auto mechanic but I play one at home. Had a leak and replaced the raditor. Had no heat thought that replacing it would solve problem but it didn't. replaced thermostat a year ago. any other ideas. I had heat up to about 2 months ago.

            Hi Doodle, glad to help! The installation process depends upon the skill level of the person performing the operation. For help with your project, I recommend purchasing a Haynes or Chilton repair manual specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

            Unfortunately we are unable to diagnose what is wrong with your vehicle without being able to be there with your vehicle. We highly recommend taking your vehicle to a reputable shop to have them take a look at it to determine the cause.

          • A:

            It is extremely difficult to diagnose a coolent leak without knowing the make, model and year of your vehicle. Typically if there is a coolant leak inside the vehicle then yes the heater core would be suspect. However if you don't know that or you are unable to diagnose the problem then I highly doubt that you are up to the task of changing out your heater core. In most vehicles it is a VERY involved process. Usually involves removal of the dashboard along with various other componants. Very involved and time consuming. Not reccomended for novices.

            A:

            They’re constructed of premium OE-approved materials. Advanced, high-strength alloys reduce premature failure, even in harsh, corrosive environments. The core tube has an air-side braze liner which is the first layer of defense against corrosion. If corrosion should reach the core layer, a band region of special alloy elements will force the corrosion to spread uniformly over the entire surface, rather than allowing the corrosion to continue down through the material thickness, causing pitting. An extra water-side layer is made up of a high-percentage zinc alloy which also acts as a barrier, providing enhanced corrosion protection and longer product life.

          does this heater core deal with my a/c ...anything with the a/c??

            A:

            It does play a role with the heating and air system. Coolant passes throught the heater core and then the A/C system blows air through it kinda like a radiator and the heater core warms it up. This is where the heat comes from through your vents.
