Question about Chevrolet Cavalier

2 Answers

I am attempting to remove/reinstall the Evaporator Core in a 1999 Chevrolet Cavalier 2.2 coupe. Am I going to be able to do so without removing the entire dash? In other words, will I be able to access the Evap Core by removing only the black plastic cover panels beneath the dash? Also, is there an easily explainable order of parts removal that will be beneficial for me to know? Thank You.

In order to replace the evap core, you will have to remove the entire dash. A guideline, or general order of parts removal would be:

  • Remove lower panels beneath the dash.
  • Remove the lower dash panel below the steering wheel.
  • Remove the glove box.
  • Remove the radio and bezel surrounding it.
  • Remove the instrument cluster and bezel surrounding it.
  • Lower the steering column.
  • Remove the passenger airbag. Make sure you disconnect the battery for safety.
  • At this point you're getting close you should be able to start removing all the bolts that secure the dash.
Good luck, that's a pretty big undertaking.

Why must i discharge the air conditioning refridgerant prior to removal of the heater core on a 2003 c230 mercedes 1.8l coupe.


The reason in why you must evacuate the a/c system with an a/c machine before you can remove the heater core is because the evaporator is located inside of the heater core box assembly. So before the heater core box assembly can be removed the a/c system must be evacuated then you can disconnect the a/c lines that go through the firewall to the evaporator.

Our front ac is not working and back is cold in our 1999 GMC suburban, we tried putting freon and it didn't work


Dual zone front/rear ac systems have 2 evaporator cores. And 2 orifice tubes, which are just inline
filters. Either your front evaporator core or orifice tube is probably stopped up.

Sometimes you can get to the evaporator cores without removing them from the vehicle, and clean it.
Evaporator cores do get stopped up sometimes, because the blower motor pulls in air with dust and debris from outside, and the air is cooled when it passes through the evaporator core.

But evaporator cores are a nightmare to replace, you usually have to remove lots of stuff under the dash and lots of stuff under the hood to remove them.

How to replace the heater core on a 97 chevrolet cavalier


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.

Replacing a heater core


YOU DO NOT NEED TO REMOVE THE DASH BOARD. IT WILL BE BEHIND THE GLOVE BOX. LOOK UNDERNEATH THE DASH AND YOU WILL NEED TO REMOVE A PANEL TO GAIN ACCESS TO THE HEATER CORE. THE PANEL WILL BE ABOVE THE PASSENGERS FEET ON THE FIREWALL.
