SOURCE: 2005 impala instruction to remove heater core

oh, sucks for you!! i just replaced mine. it was a total pain in the ***. make sure you run the car up on some car ramps. this will help you quite a bit. because there will be times you'll be standing on your head, and in some horrible positions. it takes time and it takes patience. also make sure you have the correct heater core before you start. thanks to autozone, i drove around for about 3 days with the dash tore apart and the heating system bypassed because they gave me the wrong one. my recomendation is take your time. taking apart and putting together. 1/4 in drive metric set is handy to have. im no mechanic, however im also pretty handy and very mechanically inclined. i'd say with taking apart and putting together it probably took around 9 hours. but i was also by myself. lots of dash taking apart. and my car also has the center console, which didnt help my case. good luck!!!!!

Your heater core is clogged. You can fix it. Disconnect the two heater hoses and put one into a bucket. Use an air compressor to blow into the other - it'll flush the contents into the bucket. Then reverse it - put the hose you blew into, in the bucket, and blow into the one that was in the bucket. This way, whichever side of the core had the clog, you can blow it out. Reconnect the heater hoses, and then burp the system or you can end up with air bubbles in the cooling system that can cause you to overheat. Click my screenname, go to Tips and Tricks, and follow the procedure there - it'll walk you through the whole procedure step by step.

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.

2008 Chevy Impala, was in a front end collision, the heater only blows hot air when the rpms are above idle. when at idle it blows cold. Any ideas?


There's probably a little vacuum actuated valve in one of the hoses going from the engine block to the heater core. make sure this valve is working.

Also... check coolant level

and

Your water pump may be marginal, only circulating adequate collant at engine speeds above 1000 RPM or so.
