      Parking brake release handle linkage rod from the parking brake mechanism located on the left cowl side inner panel. Instrument panel wiring harness connector from the parking brake switch located on the parking brake mechanism. Three wiring harness connectors (body wiring harness, headlight, dash) from the 3 junction block connector receptacles located closest to the dash panel. Head light/dash-to-instrument panel bulkhead wiring harness connector screw and disconnect the connector. Instrument panel-to-door wiring harness connector located directly below the bulkhead wiring harness connector.

your heater core is inside the big black box under the dash on the passenger side. you'll have to pull the dash out. then remove the black box, usually there are bolts on the firewall in the engine bay that hold it in place.disconnect the ac lines and heater hoses. remove the box and then the screws all the way around it to open it up. replace the heater core and reassemble. you'll have to recharge the freon when you are done to have ac again.

When driving i smell antifreeze on my 2000 dodge ram 1500


Check your level. If it's low, you have a leak. If you smell it inside, it may be a heater core problem. Get it pressure tested if you don't see any leaks. This will find it.

How to change a heater core


Once you pull the dash out and get the old core out. If you have a copper one take a tubing cutter and cut the tubes in half that go through the firewall.Grt yourself two half inch copper couplers.Run the two pieces through the fire wall then drop the core in place connect then solder. If aluminum similar cut then flare both ends then connect with rubber heating hose and clamps and away you go. Then you don't have to disconnect air conditioning.
