Dash removal on 97 chevy s10

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.

Disconnect the battery negative. Remove the radio, air conditioning control panel, measuring instruments, remove 4 bolts that attach the steering column at the bottom of the dash has a tube that is clamped by two screws to remove this tube is divided into that part of the steering column remove that section of the tube to the steering column complete fall on top of the dash carries cristalhay nearly three screws to remove and so the dash is free and can be moved. down. we have to download or pick up the 134A freon air conditioning system to remove the air filter off the liquid line to disconnect the water hoses that enter the calentador.Ahora remove the screws holding the case where the evaporator and the heater is We can get out and disassemble the box to get the heater

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.
