Does Your Vehicle Need a Heater Core Replacement?


Does Your Vehicle Need a Heater Core Replacement?  

Today's troubled economy has resulted in massive unemployment, and has forced many of us to learn to be more self-sufficient by doing whatever we can to stretch our dwindling funds. Unexpected car or truck repairs are notorious for taking a huge bite out of our ever-tightning budgets.

One common repair that takes a big financial bite is a heater core replacement. Depending on the particular vehicle, replacing the heater core can cost from several hundred dollars to over $1,000!  The high cost is due to the location of the heater core in the vehicle and the amount of labor required to gain access to it.  

It has been said that some manufacturers begin with the heater core and build the rest of the vehicle around it. On some vehicles, this statement seems to be very close to reality. For more information about the location of the heater core, see our article "Where is the Heater Core?"


Where Can I Buy a Replacement Heater Core?

Heater cores can be purchased at your local auto parts stores such as Auto Zone, Advanced Auto, and most other parts stores.

Ordering online is a handy alternative that can save you some money if you can afford to wait a few days.  Popular online stores such as Amazon.com carries a wide selection of products that are shipped quickly (most products arrive within three days) with FREE shipping plus there is no sales tax for most states. This can add up to considerable savings compared with most neighborhood parts stores. 

Replacing a Heater Core

Replacing a heater core can be a daunting task, but is well within the capabilities of most home mechanics. The primary requirements include a variety of hand tools, detailed step-by-step heater core replacement procedures and a lot of determination and patience.

We hope you will enjoy your visit with us today as you learn all about replacing a heater core in your own vehicle.

Hello, I just purchased a 1999 Dodge Ram 1500 Club Cab and I have a tremendous bad smell of anti-freeze in the cab, but no visable signs of a leak on the interior of the floor. Can you possibly send me instructions on how to change the heater core as it could be a pinhole leak that is totally stinking up the passanger cab, and possibly fogging up the front window a bit. Any help would be greatly appreciated.

Thank you,

Howard

I have a 2001 Buick Century Custom with a V6 the AC will only blow cold air on Max and the air is very cold. However there is a leak from under the glovebox. When I pulled back the floor carperting it was wet I observed a drip of liquid falling from directly beneath the glove box area. I was told that the heater core had a leak is this the case ? Would this condition explain the fact that the AC will only work on the Max setting ? I would apprieciate any feedback that I can get. In addition to this if anyone has replaced a heater core in a Buick I would welcome their help and tips a big thanks in advance. Natalie......

Additional info.

The plastic core cover won't come out so I can pull down on the core itself to dislodge it from the firewall. I notice a plastic push type plug atachment sticking out the engine side of the firewall. Is this an attachment that may be holding the core cove to the firewall? I don't see any bolta anywhere. I can pull down on the cover from the front. The core is loose but I don't have enough room to pull it down and out with the cover still in place. I'm thinking of cutting the plug protruding from the engine side of the firewall, as I can't seem to pop it loose.
