Do you have to remove whole dashboard on 96 gmc jimmy to remove and replace heater core?or can you do everything from underneath the glove box?


  1. 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.
  2. Remove the radio, headlight switch module and glove box by turning their screws in a counter-clockwise direction.
  3. 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.
  4. 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.
  5. Remove the heater core hoses, 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.
  6. 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.
  7. Replace the heater core with a new one by sliding it into place and securing the mounting bolts.
  8. 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.
  9. Reconnect the dashboard to the firewall, then replace the front dash panel and fasten its instrument cluster screw and bottom bolts.
  10. Crank up the truck and add coolant until the heater core is filled and blowing hot air.
  11. Replace the radiator cap.
The Jimmy uses a coolant-heated radiator core mounted in the dashboard to provide heated air into the passenger compartment. This heater core can become clogged and leak, as it is usually the lowest point in the coolant system and debris settles into it. Replacement of the heater core will take the average of about two hours to complete. Good luck

Remove Dash On 1988 Camaro IROC


You do not have to remove any part of the dash at all! All you have to do is use a socket wrench from the front of the box with an extension over the top of the box. There is even a dip in the box at this point that may have been designed to make it more accessable. I have a 1988 Camaro and removed this impossible to reach 5th bolt by using a 9/32 socket and an extension or two to get the right lengths and a universal joint for easy manouvering. My son helped by holding the socket on the bolt while I did the unscrewing. It helps to have a good variety of socket wrench extensions and a universal joint and a skinny arm to get behind the box. The fifth bolt is about 3" in from the upper right bolt. Same size bolt as the other 4.
