Removing a heater core from a 2000 s10 blazer

SOURCE: removing/replacing a 2000 kia sportage 4x4 4 dr heater core

The heater is located under the dash board to the right and down from the radio. To remove and replace it you will have to remove the dash board down to the fire wall. Also, you will have to disconnect two hoses that connect up to it from the engine compartment. These are located in the back of the engine and down on the firewall about midway. Once you remove the dash board and locate the heater core you will be able to see the location of these two hoses. Removing the heater core is time consuming but it will save you about 700 dollars.

it is located under the dashboard against the firewall of the passenger seat. i recomend buying a repair manual from your local auto parts store before attempting as it requires draining, flushing, refilling and bleeding the cooling system as well as removing many other componets like the entire dashboard and thermostat

SOURCE: Replacing heater core in 2000 GMC sonoma. Dash is

If the dash is removed you've saved about 9 10ths of the job endurance. Look around, what you believe to be, the perimeter of the heater box. I cannot, and no one else can, tell you exactly where the bolts and nuts that mount the heater box are. Therefore you must viually sixe the box and check outide in the engine compartment and inside under the dash for the mounting bolts.You'll want to start by removing the heater hoses. Then starting at the passenger side engine compartment look for a group of 10mm or 7/16ths nuts retaining the housing and remove them. Do the same inside. The housing is usually held together with screws or clips, it changes year to year. Keep a log or pix of the wires and cables and hoses(vacuum) that are connected to the housing for reassembly. You'll need to "roll" the box out from under the dash depending on how much of the dash has been removed. The core is easy to spot for is has two hoses sticking out, and, is encircled with clips or screws . Also make sure you remove the bracket around the two entry hoses if it has one. Thank you, Dana
