Heater core replacement procedure 99 S10

You don’t need to remove the dash or remove AC refrigerant from 2005 Chevy Uplander. Its a simple job takes about an hour with 10 mm socket and Phillips screwdriver. Core is in the center of dash near the floor. Remove lower panels on center of dash where passanger
Left leg and driver right leg would be. Also the front lower panel where cigarette lighter is. They pop out. Also remove fiber cover from under glove box and driver area. Remove large black plastic member behind where the lower center panels were. Two black screws in front and seveal screws in either side. Pull to rear to slide out. Remove metal bracket on floor with 4-10mm. Remove vent from floor pops out. Look up underneath from area you created under center of dash. Many vertical gold colored screws. Remove first cover panel 4 screws. Remove second panel mores screws. Theres one clear against firewall by driver side also. After this heater core is accessible held in with only one screw by firewall remove it and core drops out easily after wiggle out pipe ends from firewall holes. This is about 20 minutes to this point

Before remove heater core, drain coolant, remove front engine yoke bolts, ratchet strap engine pull forward and block. Pop out windshield wiper link and brake booster vacuum hose so can reach hose connections from engine side. Remove hose clamps and disconnect hoses to core. One hose is 3/4 id and the other is 5/8” that necks out to 3/4” on other end.

The hardest part about the whole job was getting the hoses off then in with these spiring clamps and finding the right replacement hose and connectors. Not the removal of the core which is surprisingly easy.

pull the dash off theres the heater core on passenger side theres a inlet and outlet hose pull both off remove mountin bolts install new one reassemble dash

No you do not, I think you mean the heater core, because its leaking, first unhook heaters hoses under hood (there may be a clamp on the core tubes that has to come off), next go under dash on passengers side, take the one bolt to the far right under dash by the dome light, thats so you can pull the dash out just enought to get the cover off the front of the heater box, behind that cover is the heater core, now that cover is held on with about 6 1/4 inch screws give or take 1 or 2 when you get the cover off you will see 2 straps, one on each end that hold the core in place, there are 2 1/4 screws in each one, remove them and core will come out. Put back together in reverse order.

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.

Good luck and make sure you have lots of time and use the camera on your cell phone and take pictures to use as reference.

you have to remove the whole dash which is very difficult because ot the many hidden screws and wiring harnesses.than you will have to take out the entire heating and cooling module

the whole dash has to be removed.the book give about 8.0 hrs to do heater core.

no you can split the heater box under the hood but be careful they will break very easily

If it wont pull out then something is definetly holding it in. Take your time and double check everything
