96 Chevy Tahoe Heater Control Valve

[@jo2reco]

9 years later. You helping people. Nice. I just got my 99 Tahoe out the shop for replacement of water pump. 3 days later this exact part broke. I barely got it home before it completely overheated. Your video really help me replace this. I’m not mechanic but I can turn a screw. Thanks

[@stewharr]

This happened today on my 99 suburban. Went ahead and ordered the ACDelco part from Amazon. The reviews for the aftermarket ones that my local parts places had in stock were all bad. Will wait an extra day and pay $10 more to do it once. Thanks for the video. I have that hose clamp tool too.

[@churchlj8055]

The heater control valve can make this type Tahoe overheat and void all contents of your cooling system in no time. Watch your gauge and if it happens rapidly look at this.

[@drewsquickfix]

If you replace your heat control valve you might want to replace your hoses in that area too only take a few extra minutes. Heater hose is only like $2.00 a foot . Worth the extra time to prevent more coolant loss later. I have a video showing this on my channel.

[@StanixGarage]

Great feeling when you discover the big problem is an easy fix. I need to get one of those hose clamp tools.

[@chevybrat]

Nice presentation, and without F bombs! Hahaha. I'll have to do the same job as my old 99 Burb has a broken valve. Thanks for posting!

[@cartierrowlette2608]

Hello. May I ask where did you get your hose clamp at?? Very cool tool to have. Please let me know, going to fix that HCV tomorrow. Thank you very much for the info.

[@timbo9095]

Man I gotta get me one of them hose clamp tools. This could have saved me time and money.

[@coreyhattenstein]

I need one of those clamps pliers. I hate using regular pliers

[@impalass0250]

Where did you purchase the tool to help you remove the quick clamps on this Tahoe

[@alphasaiyan5760]

Very common issue with these systems. They make one that’s made out of aluminum and not plastic. However , the vacuum line part is still plastic I believe. It’s just really a regular maintenance item.

[@Benjbugarin]

I just did my 94 2500 suburban 2wd thing. 454. Heater core. Not to bad. But...larger hose to heater core seems loose. Drip drip drip. After installed everything back. I twisted hose to left. Stop the drip leak. But. I could not see all way back to notice the position of clamp. Im have to recheck after work. Tomorrow. Other than that. Gave wife some distilled water andncoolant for the road. 😏

[@anthonymiller5540]

Thanks Dave have a good one happy holidays

[@livinlovinlaughin99]

Where does the little vacuum line on the valve attach to?

[@legendarygreatsword6126]

Perfect exactly what I needed

[@alanrock310]

Saved me a lot of money. Thanks

[@americanwhiteboy715]

I need to know what side is the in let to the core the straight line or the bend line trying to flush the core and need to know what side is the in and out to put back on right

[@marcuviusblack5781]

This video was very helpful. Thank you.

[@MacMayne]

Where did you acquire that tool from?

[@damaryslopez8801]

Should I drain out the coolant before switching out the valve?

[@icek9a]

What size vacuum hose does the heater control valve use?

[@nancyheaton5471]

Thank you !!! My 99 suburban had the same problem but it was at the cap part of the heater valve and I Love that tool you have! Where can I get thst?

[@richcollins513]

Can anyone explain the need of the valve and how control of the valve is done? Thanks

[@CodyOnGuitar]

I have a 95 Tahoe and the vacuum lines are missing from the heater valve and I have no clue where they are supposed to go... I’m having a overheat issue and after changing the thermo and the heater core and the valve it’s still overheating... any suggestions?

[@Trapper50cal]

A good way to ID if this is your problem....look in the front passenger wheel well, if the frame rail behind the tire has fluid stains...this is prob. your issue.

[@JMU365]

Hey how did you disconnect the piece that has wires coming from it?

[@kylesmith9649]

Where does the vacuum hose go to on the control unit?

[@vizguru]

Dave, I've had to change the heater control valve of my 1999 Chevy Suburban multiple times, at least: 1. Myself - though I'm listing myself first, I was the 3rd or 4th to take a stab at this. 2. Shop in Bellflower, CA 3. Shop in San Jose, CA. This shop also installed all new hoses and remarked the diameters I had used didn't match correcty. 4. Changed by a friend 5. Just changed by a mechanic who rebuilt the engine as a precaution since he could see it was leaking. Yesterday, after my first long break-in drive, I see it leaks! Any ideas how I can fix this once and for all so I can put real coolant and be able to see the correct level in the reservoir, something I haven't been able to do for over a decade.

[@dannykneeskern3184]

where do the 4 hoses rut to/from? pease let me know....I have the heater core hses located but cant find the other 2.....thanks!!!

[@allanbrogdon5317]

Mine broke while I was feeling for any other vacuum lines that may need replacing.I ran a finger under it and it broke . Thankfully in the driveway.

[@lorrilynn7837]

Hi there i wanted to know what are those two wire's called that's be hind the alternator

[@calvin-]

Nice video, man. This was just what I was searching for. 👍🏻

[@ronthemogul]

Hello I have 96 Tahoe 5.7 as well. I'm having issues with the a/c blowing cold nonstop. Would this part you're speaking of have any play in that? Maybe a missing vacuum hose? I'm lost on this one. Thanks

[@ronthemogul]

ok after i inspected the heater valve i noticed that the vacuum line to the left of it is missing. What does that connect to?

[@johnbeer5242]

i got to put a heat shield mine is too close to the exhaust manifold on a 95 chevy Impala

[@1dr3am3r1luv]

used this to replace mine thx for the help

[@johnharrison5098]

where does that vacuum hose go?

[@fosterfamilyfaith]

Is this part onpy neccessary with rear heat?

[@sonataq14]

Can anyone tell me...does this control valve....control the heat in the rear of the vehicle as well as the front? I have a suburban which has a rear heater core, and I was wondering if this valve controls the coolant going to the back?

[@radcam69]

Personal preference but I prefer worm drive clamps.

[@pammyers4730]

Would a bad heater control valve effect the ac?

[@1BMWdrvr1]

Hi, Thank you for the video. I have a '98 2500 Silverado and am wondering what is the small "elbow" tube @the firewall where the two hoses enter. (Near the control valve you replaced). It seems to drip some water but I can't see any other part that would connect to it. Is it just a "condensation" outlet that normally drips a bit of water? The hoses at my firewall look the same as the '96 you repaired. Thank you for the video. PS: I hope you got to move to a place you like better...

[@YeskaSmoke420]

How do you take off the air box?

[@tdjacks56]

how do I change my heater control valve on a 745i 2003? n where did u buy that tool from for tha holes whts tha name of it also?

[@UFOGHOSTHUNTER]

They're "Hose clamp pliers" & sold at O'Reilly or Autozone.

[@londonsweeps]

You didnt mention where the vacuum line goes.

[@janh9829]

Watched your utube on 96 Chevy Tahoe Heater Control Valve and replaced it but I still don't have heat. When I accelerate I feel heat only? Help

[@davesgarage512]

Could have a little bit of a clogged heat core

[@UFOGHOSTHUNTER]

Flush the heater core. Change your thermostat, easy fix and great heat♨

[@tonyinfinity]

Probably a cracking hose for the vacuum, when you accelerate it's getting enough vacuum to open the heater control valve.

[@kyleheitzman1708]

Quick and easy if all the coolant is drained

[@neilybless2399]

good looking out homie !!

[@joseacruz3627jc]

where does the vacuum hose connect to?

[@mochanic5498]

To the solenoid mounted on the firewall, you can see it around the 4 minute mark, it has a blue connector on it.

[@ernestkilgo4961]

Thank you came in handy

[@martinarrieta7779]

[@davesgarage512]
