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

There is a black covering on passenger side that should have four screws in it. You should find the heater core hidden inside the casing.

SOURCE: 1999 Chev Venture Heater core do I need to remove

The blower motor location can change from year-to-year. It can also change with the trim level of the vehicle. A vehicle that has front and rear climate controls may be configured differently than a vehicle that has front controls only. The following are two different repair procedures. One is for blower motors located and accessed in the engine compartment, the other is for blower motors mounted inside the vehicle.

REMOVAL AND INSTALLATION

Engine Compartment Mounted

  1. Disconnect the negative battery cable.
  2. Remove the engine air cleaner assembly.
  3. If necessary for clearance, remove the left hand wiper arm linkage.
  4. Detach the wire harness connector from the blower motor.
  5. Disconnect the motor cooling hose.
  6. Remove the blower motor assembly retaining screws
  7. Carefully pull the blower motor assembly out from the firewall.

I would like to know how replace my heater core on a 2001 S10 chevy blazer


Instructions
    • 1Remove the dashboard. The heater core in S10s is behind the main dashboard, and it must be removed to access the core. The front dash panel can be removed by unbolting several screws at the bottom of the panel, then pulling the panel away from the dash. Once this front panel is off, the primary dash can be unbolted from the firewall with four large bolts below the windshield. Several accessories may need to be taken out to unbolt the dash from the firewall, such as the radio or 4WD switches.
    • 2 Drain the coolant from the core. There is a drain plug at the bottom right of the primary radiator that will empty the coolant system when unscrewed. Some residual coolant might remain in the core, but it will come out when the core is taken out
    • 3 Uncouple the core from the coolant lines. These hoses are directly behind the oil filler tube and will come loose when squeezed with pliers. They are of different sizes, and it won't be necessary to mark them for later re-attachment.
    • 4 Unbolt the core from its mounts behind the removed dash panel. Several bolts might be difficult to reach, but once free from the mounts, the core assembly slides up and out toward the interior of the truck. Lay a towel down when removing the core, as come coolant might splash out.
    • 5 Insert the new heater core and bolt it into the mounts. The openings will fit into the holes provided in the firewall.
    • 6 Reconnect the heater core hoses, and re-attach the dashboard and front panel.
    • 7 Fill the coolant system with a 50/50 mix of antifreeze and water. Tighten the drain plug on the radiator, then fill it. Crank the truck up with the heater system on its maximum setting and continue to pour coolant into the radiator until it will not take in any more.

How to get to the heater core in my 1988 chevy s10


If it is necessary to remove the heater assembly, the cooling system must be drained before removing the heater core.
When a heater core leaks, a new heater core is installed or the old one repaired.
Heater Housing
  • The heater housing is usually under the dash and must be removed to gain access to the heater core.
  • Procedures for replacing the heater core vary with the year, make, and model of car. It threfore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.

  • Remove the access panels(s) or the split heater/air conditioning case to gain acess to the heater core.
  • Remove the heater coolant hoses.
  • Remove the cable and/or vacuum control lines (if equipped).
  • Remove the heater core securing brackets and/or clamps.
  • Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing.
  • To reinstall the heater core, reverse the removal steps.
When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

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.

How to remove heater core in a 98 blazer


You have to remove the dash in layers. There's a whole bunch of screws to take out. The heater core is located in the middle of the dash near windshield when you get that far. There are a couple of brackets that hold the heater core in place, remove the heater hoses and pull out heater core. It's quite a long process so give yourself plenty of time.
