Please God let this not be the cause of my no heat problem. Lmao! Thanks for this detailed video though! hoping I don't have to use it.
I really hate automotive engineers. I hate them more than politicians.
Hello! I’m Amber, representing an OEM dashcam manufacturer. We’ve been focusing on crafting high-quality dashcams for years and are eager to explore potential collaborations with you. Would you mind sharing your email address? I’d love to send over some details about our products—including specs, customization options, and past collaboration cases—to give you a better sense of how we might work together. Looking forward to the chance to connect further!
Thank you Feesher!! Average quotes in my area for a 2009 G6 heater core replacement in December 2024 were around $1100. Saved around $700 doing this mostly myself over a few evenings. This was my first ever car repair and it was surprisingly easy with your video, enough determination, and a few colorful metaphors. Advice to anyone trying: I hope you're a decent contortionist and make sure you have a socket extender to get the ones in the far back nearest the pedals (the accelerator does NOT need to be removed, but I see why another video opted to – it's kinda tight back there). I went with manual tools the whole way like a glutton for punishment. Also, once all the screws were out, I still had to use a significant amount of force to pry open the HVAC box and resorted to using a blade to pop it open (hence the colorful metaphors). No apparent damage to the housing but maybe I was lucky – didn't care at that point. Putting it back together was also a pain but satisfying because once the HVAC box is back on, it's basically a cake walk from there. Don't forget to protect your knees because you'll be kneeling a lot – I used old couch cushions for lack of a better nearby option.
BACKSTORY & COSTS: The previous owner had bypassed the core by slicing and ripping off the old hoses and connecting them with a small U-shaped hose, requiring replacement of two hoses inside the engine compartment. I bought the core new from a repair shop for about $120. Hoses from 2 places for about $50. Ratchet extender set for $10-15. If you have to replace hoses, Duralast is fine but do NOT get D87763 for the return line from the core to the engine (AutoZone website said "heater to engine" and I called a local store to check before buying but the inner diameter was actually too small). The correct model hose for that section is 86109ADV (I assume ADV is just a reference to Advance since the local GM dealer sourced it from there but that's what's on my receipt). The tiny straight "heater to tee" hose worked perfectly for the supply line (I used Duralast B87612 there). It's been below freezing for 2 weeks with -3F coming in a few days so I splurged at the end and had a dealership install the hoses for just shy of $200 including coolant (still saved a respectable amount overall plus got an education). All in all, spent just shy of $400 but, if you don't have to replace hoses, it can be done for around $150 (including coolant), maybe less. Good luck and thanks again Feesher!!!
No dash removal! (Removes entire dash)
