2007 Chevy Express Van Heater Core Removal

This Chevy van had no heat. After we checked it out we found out that the heater core was clogged up. So in this video I show you how to remove it. Be sure to watch the bonus at the end to see the stuff that was clogging the heater core up.

Thanks for the video. Getting the core out after all disconnects made was extremely difficult. There are some kind of factory clips right where the core lines penetrate the firewall. I cut them off and pushed the flared ends back into engine compartment. I absolutely used this video. Thanks again.

Are the heatercores directional? As in flow of coolant?

[@TheGAutomotiveAndMore]

I do not think it matters anymore. But on old cars the inlet and outlet were different sizes, 5/8 inlet and outlet 7/8.

Im having some serious trouble with "but then that heater core should just slide out 3:30 I see from other videos and the chilton manual that pre 2003 models have another retaining clip whete the tubes go through the firewall, I wonder if there's some less accessible bullpoo that Chevy replaced that with that's giving us grief

[@elijahzarei]

Thank you for your helpful video. My chevy express smells bad while Im using the heater.How can I fix it?

[@TheGAutomotiveAndMore]

If the heater core is leaking change it.

[@lisamaurizi4274]

Is it recommended when replacing the heater core to also do the water pump & radiator to prevent the build up again?

[@TheGAutomotiveAndMore]

I would flush it out really good and replace the radiator. I would only replace the water pump if its leaking.

[@elijahzarei]

What tools did you use for cowling drain?

[@TheGAutomotiveAndMore]

Sorry I do not remember.

[@elijahzarei]

@@TheGAutomotiveAndMore I can't remove the cowling drain.

[@TheGAutomotiveAndMore]

The video said that the are a 10mm headed nut so I always use a deep socket and a extension.

[@skliros9235]

Is there a water control valve below the hose connection?

[@TheGAutomotiveAndMore]

Yes there is. Thanks for watching

[@marcoheredia1712]

Now that the box is cut open A bunch of hot air escapes and wont push heat to the drive leg vents 😢

[@tomshaw661]

what did that job cost the customer?

[@TheGAutomotiveAndMore]

Book time is 4.0 hours

[@randalldavis1828]

Thanks u very much for your video

[@norris.7670]

👍

[@GGarcia7111]

A flush back wouldn't do the job??

[@TheGAutomotiveAndMore]

I did do that the year before and it gave him a little heat. But then it just stopped working again. The stuff in the heater core was rock hard. So no flushing it wouldn't do the job. Thanks for watching

[@ehcatsfaneric2211]

what is a parts and labor cost for this job?

[@TheGAutomotiveAndMore]

It is 4.6 hours labor and what ever the parts cost.

[@GeneSotdorus]

Core was probably clogged fro a store stop leak

[@TheGAutomotiveAndMore]

Probably.

[@titovillarreal119]

The problem was the owner used a gasket sealer mest up the heater core he didn't know how to use it 😂 your need to take the thermostat off add the sealer liquid follow the instructions

[@TheGAutomotiveAndMore]

Possibly
