Too many steps to post here and even more if the vehicle has AC. I would recommend purchasing a shop repair manual for that vehicle if you intend on DIY.
Its your Heater core if it smells like a syrupy sweet smell if not then its your thermostat
wayyy more then its worth. $800 or more. itll cost you $43 to do it yourself.
I have a 2002 Chevy SilerRado 1500 Pick up Truck, 2 wheel drive. My broblem is with the heater not coming on. I checked the fuse Box on the drivers side of the dash board label HTR/COOLING. The fuse was ok. I would like to know how to locate the Heater Core and replace it if possible. I haven't checked the thermostat. thanks in advance
same procedure as yesterday
what is the year model? 1995
In order to get to the heater core you will have to remove the dash. If your Dodge is like mine and I am assuming that you are wanting to replace your heater core because it is bad then it will take a lot to get this job done. First you need to drain your system of coolant, remove your negative battery cable. The dash has different kind of fasteners. It is held in place with screws and clips. According to the Chilton manual it requires the ac system to be discharged and the accumulator to be removed when replacing the heater core. I'm checking it out to see if I really will have to do this. If you are still in need of help you can e-mail me to see where I am at on the replacement of my heater core.
If it is leaking under the truck it is not the heater core that is leaking. It would leak inside the vehicle on the passenger side. There is a drain tube for the A/C that is under the vehicle on the passenger side, and water from that with the A/C on is normal. If it is coolant, check the heater hose connections at the firewall. If you find that the heater core is actually leaking, replace it. No other repair is permanant.
first you will have to remove your heater hoses going to your motor to the firewall take them off at the firewall, then there is a big box on your firewall, there is a bunch of screws holding it on remove them you heater core will be inside it.
You'll need to pull much of the air shroud under the dashboard. Once you expose the heater core you'll need to disconnect it from under the hood. There are a few studs near the heater hose connections that hold the core in place. Pull them only after you've removed enough of the air shroud to get the core out.
under glove compartment take time removing
You'll have to drain your coolant and disconnect the two coolant hoses that go to your heater core at the firewall. Remove the 2 bolts you see between the hoses on the firewall. Inside, you'll have to remove you entire dash. The support bar that runs from door to door needs to be removed. From here, the linkage from the controls needs to be removed, the screws securing the heater core housing to the rest of the ducting and A/C core need to be removed. There are a number of nuts that must be removed at the inner firewall as well. The heater core housing is 2 piece. Unscrew the retainer screws and separate the 2 halfs to expose the core. Good luck!
Remove your heater hoses from the core (cut them if necessary) and join the two ends with a heater hose coupling. Use screw ring clamps to secure the lines to the coupling. You can pick up all these parts at any major autoparts store.
