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.

SOURCE: i need diagram and/or directions for removing the

Just replaced my heater core 2000 silverado not a quik job but u can do it.Took alot of patience and about 10 hours of time.Just completely take the dash apart layer by layer.First thing is the trim around radio and controls just snaps out.Piece under wheel just snaps out also.You will see all the small screws that have to come out to disassemble the next layer.Pull out the radio,heater controls,air bag switch unplug them,just remember the wire routes maybe write them down on paper.Pull out the vents.The whole top dash cover after unscrewed;lift up alittle and pull back it just slides back from under the catchers near the windshield.You will also find a couple bolts on each side of the door with pins for alignment to take out with door open.You look up under the air bag assembly there will be a bolt on each end take them out.My airbag switch was OFF!unplug wire hareness here also.U will encounter a few wire harenesses to unplug as u go.There will be 2 flat u shaped pieces u dismantle that holds the dash covers on a bolt in each end.One on each side of dash.YOU WILL SEE the black airways that run to vents runs the width of dash this will lift out.I did not take the steering wheel off BUT it may be easier if u do I just tried moving the dash sections out of my way and worked around them resting one end on the pass seat.The big reinforcement piece of steel I unbolted from the pass side and just slacked the bolts up on the other end near the wheel so I could move it back and up alittle.You will see a cover to the right of center with 2 screws this is heater core cover but there isn't room to get it out.U will look under the hood behind center of engine on the firewall there will be 3 bolts to get out.IF you have air conditioner it's on the left side looking in there is 3 bolts here to take out and you also have to take the 2 nuts off the air conditioner unit and step back let it LEAK SLOWLY.Now you should be able to pull the whole air heater box unit back and down enough to get the core up and out of the slot.I done this alone but when it's time to line the air heater box up and slide back into place it's real frusterating should have a friend and probably a 12 pack during the whole ordeal!While I was dismantling everything I didn't figure I would ever get it back together but I surprised myself it wasn't that bad.Hope this helps.

Not a whole lot different. Just need to keep removing plastic down at the heater until you get to the heater core. Then disconnect it on the firewall side.

SOURCE: 2003 silverado. no heat in cabin. water hose to

Hello Harold.
The heater core on your truck has a restriction that reduces the flow to the point you have no heat.
You will need to remove the two hoses and flush out the core.
I use two pieces of hose to attach to the fittings on the core to add the flushing solvent and the water hose.
Try using a product that can dissolve calcium such as CLR or an acid based type to clear it.
Use hand and eye protection while you do this as inadvertent spray may get you during the process.
Flush it in both directions for best results.
Hope it clears your problem.

What is the process to putting in heater core in 1983 chevy silverado?


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.

  • 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.
