How do i change the heater core on my 1999 chevy silverado 1500?


Inspect/Replace 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.

I have a 1999 chevy silverado and I need to change heater core


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.

Start by draining the coolant, disconnect dash board wiring harness from pcm behind kick panels, disconnect eye shaft, unbolt dashboard and remove dash. (Remember to tape steering wheel in place as it might have a clock spring). You might have to remove some trim panel on top of dash or cluster from dashboard to gain access to retaing bolts, disconnect heater hoses from heater core in engine compartment and remove heater core, reverse install.
