Heater core instructions for 04 Chevy Impala SS

I have a 2004 Chevy Impala SS and the other day I noticed fluid leaking inside on the floor of the passenger's side. I have been asking around and am led to believe that it is my heater core that needs to be replaced. I am aware that I can do this myself, I would like to know what tools I would need and the steps to complete this process.

Before you go thru that expense. If it is water leaking,check the evaporator. Sometimes it gets plugged with debris. So first, decide if it is water or anti-freeze. Also, I have taken the heater hoses off of the inside of the motor area and flushed the core out. It works on some.

Why doi hear water in the dash on a 2004 chevy impala


That's the antifreeze entering and exiting the heater core, which is located behind the glove box of the dashboard. If there is sweet smell or antifreeze on the inside floor on the passenger side, you have a leak in the heater core.

2000 Impala leaks coolant out hose in firewall


It sounds like you're looking at the heater core water lines. These connect to the heater core supply and return inlet and outlet pipes to bring hot coolant into the cabin for heat and windshield deicing.

The heater core is a mini radiator and operates on the exact same principles as the radiator does. The heater core is located behind the dash board on the passenger side. Look for a wet spot of antifreeze on the passenger side floor area - close to the firewall for an indication of a leaky heater core. If it is leaking, it will likely need to be replaced. This can be a pricey repair.

Good luck!

How to Replace the Heater Corein a Chevy Impala

Replacing your Chevy Impala'sheater core is no easy task. There are several parts you must carefully removeor reposition to disconnect the core from the heating, ventilating and airconditioning (HVAC) module. This module and the core are located behind thecar's floor ducts.

1. Jack up the car and drain the Impala's cooling system.Loosen the water pump's drain bolt and let the coolant drain into a pan. Closethe drain bolt and lower the car afterward. 2. Remove the heater outlet and inlet hose from theheater core (reposition the hose clamps to do so). Take off the right consoleextension panel, body control module and left side extension panel on the frontfloor console 3. Disconnect the leftinstrument center support bracket (pull away the carpet at its bottom to reachthe nuts). Remove the accelerator control pedal from its position in the frontof the dash. 4. Disengage the center floorducts by raising the outlet duct while pushing the ducts down. Rotate theoutlet duct forward in the car and pull down to remove it from the HVAC module. 5. Use a small chisel to removeall the heat stakes from the heater core cover. Loosen the nut behind the fuelline bracket. Remove the dash panel's stud at the heater hoses. 6. Pull the core's cover downenough to reach the HVAC module's locating pins. Slide the cover rearward untilthe drain tube clears the dash front. Remove the cover by sliding it down,rearward, and to the right. You can now remove the core.
Installing the New Core
1. Install the new core into the HVAC module,attaching a new seal onto the drain tube. Attach the core cover from the rightside, sliding it up and forward into position. 2. Align the draintube with the front dash hole and the core cover holes with the HVAC locatingpins. Install the core cover screws, cutting and folding back the soundinsulator near the center screw to ease that screw's installation. 3. Reinstall the dash panel stud at theheater hoses, tightening the nut behind the fuel line bracket. Align the centerfloor duct with the HVAC and push it up while rotating rearward to install it.Put the floor ducts and outlet duct back into the Chevy Impala. 4. Attach theaccelerator control pedal. Pull the carpet back and position the left centersupport bracket, then tighten the bracket nuts. 5. Reconnect theleft side front floor console extension panel and the body control module tothe car. 6. Put on the outlethose and inlet hoses to the core, securing them with their clamps. Refill thecooling system with the proper mixture of water and coolant.

I am having trouble finding a coolant leak, on the firewall side of a3.8 liter chevy engine, Impala. hoses look good, new water pump. what is there up behind there to leak?


the heater hoses pass through the firewall into the heater core, which resides inside the dashboard. either one of the hoses themselves is leaking, or the heater core.

I just got this 2004 impala police car. I found coolant inside on floor. I can tell it flow from the center of underneath control console. Can any one give me idea how to fix it? Thanks Hanping


unfortunately it is not an easy fix. Your heater core is bad. The heater core is behind the glove box. you may be able to go in under the dash on passenger side, which is where it should be leaking at, and pull it out there. However, it may be easier to remove the glove box and re-install it after you change the core. YOu could have a loose hose on it, however I bet it is a bad core.

Fluid leaking onto the front passenger side floorboards.


2004 TB 60,000 miles. i was just told that the leaking fluid in my passenger side floorboard was do to a clogged up A/c hose. An A/C works by drying/ removing the moisture from the air inside the vehicle and cooling it. The accumulated fluid is usually evacuated under the vehicle which is what you see when people are stopped at a red light and there is dripping under their car. when a hose is blocked there is a vent that from some reason flows directly into the passenger side floor board. If you can not manually knock loose the block your probably going to have to take it to a mechanic.
