SOURCE: Removing the heater core from 2000 silverado

When I replaced the heater core on my 95 Suburban, I seem to remember having to disconnect the A/C lines on the firewall for the evaporator. There were also several nuts to remove on the engine firewall side from studs on the heater box that pass thru the firewall. It is definately a lot of work.

Good luck.

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.

Sorry, your going to have to remove the dash.

  • Remove the front dash panel by turning the lower screws in a counter-clockwise direction, then unscrewing the single bolt on the lip of the instrument cluster and pulling the panel out. Remove the rear wiper switch and the 4x4 switches, if applicable. Lowering the tilt wheel will allow the panel to be totally removed.
  • Remove the radio, headlight switch module and glove box by turning their screws in a counter-clockwise direction.
  • Remove the main dashboard by unbolting it at the front, between the windshield and firewall. There are six to eight bolts holding it in, and, once they are removed, the dash can be pulled away from the firewall. Be careful not to pull too much, as the wiring harness could become damaged.
  • Drain the coolant system by turning the drain plug on the lower left corner of the radiator and allowing the fluid to fall into the drain pan. Uncapping the radiator can reduce the internal pressure.
  • Remove the heater core hose, on the upper left of the engine bay by pinching their hose clamps with a pair of pliers and pulling them off. Some models will have screw-type hose clamps; turning them counter-clockwise will loosen them. Age and heat may have stuck the hoses to the core nipples, and the hoses can be cut right at these nipples if necessary. Leave enough hose to reconnect the new core.
  • Unbolt the heater core's mounts with a socket wrench in a counter-clockwise direction. Once the bolts are free, the heater core can be maneuvered toward the windshield and slid out. Some coolant may splash out, so have a towel handy.
  • Replace the heater core with a new one by sliding it into place and securing the mounting bolts.
  • Reconnect the heater core's hoses, turn the radiator's drain plug clockwise to close it, then refill the coolant system with a 50/50 percent mix of coolant and water.
  • Reconnect the dashboard to the firewall, then replace the front dash panel and fasten its instrument cluster screw and bottom bolts.
  • Crank up the Jimmy and add coolant until the heater core is filled and blowing hot air.
  • Replace the radiator cap.
Good luck and make sure you have lots of time and use the camera on your cell phone and take pictures to use as reference.

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.
f74-01.gif The heater housing is disassembled to get to the heater core. Heater Core
  • 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.

How do you get to the heater core in a chevy s10 --I have removed the dash but can not get to the heater core


Passenger side bottom of heater box remove bolt. Engine side on fire wall behind distributor remove nut. Now, on top of evaporator box remove small plate with wires on it. Look inside, remove that bolt. The heater box will come out. There are only 2 bolts and 1 nut to hold box in place.
