Sir I watched your video only yesterday. I followed your advice and wrote down the Dorman Y part number. I went by auto zone here in the Memphis area yesterday. Today is 9-23-23 and I did exactly what you said, got up 530 this morning, drank some coffee, and got to work. It took me couple of hours but it's all done and NO LEAKS! You saved me a bunch of money! BTW, my truck is a 2007 silverado classic crewcab, 4.8 but it looks exactly the same as your video so far as the set up is concerned. Thanks again 😎

[@TerenceDIY]

That's great! I am glad my video helped you. Thank YOU so much for watching.

[@usnveteran9262]

Many thank from this veteran I came across your video a few days ago after noticing a high temp reading, opened the hood and the saw the plastic connector leaking, followed your steps and my 04 Silverado is back in the saddle.

Thank you from Orlando! 2008 Silvy 4.8L 123k. I did it step by step with your vid and bought the dremel and used that for the first time as well. Worked like a charm and saved me a lot of money in labor.

Great video. I haven't run into this problem before, this video is much better than the others, kudos! I gotta say, older vehicles just don't have these problems, all the fittings are metal and ring gear clamps won't break them. No ridiculous plastic clamps. I'm so glad Dorman makes this part in metal!

[@TerenceDIY]

I totally agree with you. Thank you SO much for watching.

[@Carlos-cz8tm]

I have exactly the same problem in a 2007 tahoe. I was already scared, I thought that the antifreeze was getting into the combustion chamber or that the pump did not work but it is leaking from right there and thanks to your video I now know how to repair it 😃. thank you very much man 👍

No it's not. I have worked on MANY of these vehicles and removing those hoses can be very difficult.

You can buy some typical heater hose (5/8") / heater core hose by the foot from autozone.

[@sawyerbennett8227]

You're from the future?

[@natejohnson2177]

I watched the video and completed the job successfully. Only thing is now it running hot. What could cause this?

[@TerenceDIY]

Oh, you gotta bleed the system. Remove the reservior cap and let the truck run. Watch the temperature hand closely. The hand will probably get close to running hot but it will eventually settle in the middle as the air escapes. Once it's running normal for 10 minutes or so, you can shut the vehicle down and then top the antifreeze off. You can also top it off as it is running during the bleeding process.

[@Jon-dz2cl]

Does Anyone know the Correct Name for Those type of Hose clamps ??

[@mnight207]

Were you having any problems with overheating? I'm wondering if my thermostat isn't functioning properly

[@TerenceDIY]

After a while it would definetly start to overheat due to lack of coolant. Once I fixed the leak, it was all good.

[@mack606]

Do you have a video on heater core flush for this vehicle I was thinking of flushing through the hoses where the y connect is towards the water pump instead of unhooking hoses from the firewall since they are hard to get off. My heat is lukewarm but not hot I’m thinking it might just need flushing anyway input you have would be great happy holidays

[@TerenceDIY]

I don't have a video, but have you checked your thermostat? If it's an original thermostat, years of coolant build up can cause it not to function properly. Although it's not running hot, it can result in the heat not getting hot. You can check by feeling the hoses going to the heater core to see if they are hot when the vehicle is up to temperature. Also, if that's not the case, I would flush the entire system by just disconneting the top radiator hose and run a garden hose there, remove the cap from the coolant reservior so the water can discharge from there and the radiator or vice versa. Then, fill it with concentrated coolant only adding 25 percent water to the mix.

[@mack606]

@@TerenceDIY yes I replaced water pump and thermostat and radiator back in July and a couple of days ago I replaced the coolant temperature sensor because my temp gauge was fluctuating back and forth and then I noticed my heat is lukewarm not hot like it used to be this happened this past Friday

[@TerenceDIY]

Interesting... Question(s); was it getting hot prior to you replacing those parts? Did the temperature senseor fix your guage issue (important)? I am asking because the light bulb went off in my head after you mentioned to key things (fluctuating gauge, lukewarm heat). I will await your answers.

[@mack606]

@@TerenceDIY yes it was getting hot until I had issues with the coolant temperature sensor and everything is working as it should I just think I need to back flush the heating core but from a scale 1-10 the heat level is about 6 or 7

[@TerenceDIY]

Okay. That should help. Keep me updated.

[@mack606]

If you do a coolant flush on your cooling system and then fill with 50/50 mix is that okay

[@TerenceDIY]

Absolutely! It's actually better to use the 50/50 because it's a perfect mixture.

[@mack606]

@@TerenceDIY thank you sir ppl are saying to use a straight coolant because the engine block still has water in it and the straight coolant will balance making it 50/50 but wanted your opinion on it since you have a similar vehicle as well

[@MaudsValentine]

What's that sensor right under the junction hose you put, mine leaked onto that sensor but I can't find the name for it

[@TerenceDIY]

Is there a time stamp where you can see the sensor? I'm not sure what sensor you are referring to.

[@MaudsValentine]

​@@TerenceDIYdo you have a Twitter or somewhere I can show you a picture, it's got a small green cable and it should be directly under the junction of the hose

[@TerenceDIY]

You can send it to my gmail. [e-mail]

[@mack606]

What can cause your vehicle to slowly reach operating temperature I’ve changed all my hoses the water pump radiator the T connectors thermostat twice new expansion tank flushed the cooling system until water came out clear the only thing I haven’t replaced is my heater and it find I flushed it as well until water came out clear I basically re did the whole cooling system and there are no leaks as I can see and my Yukon is not overheating just slowly rising to operating temperature. What would be your take on this my vehicle is a 2011 Yukon Denali xl 6.2 engine. I also tested the thermostat dropping it in boiling water and it opened all the way once it got to the right temperature and also closed all the way . Thank you and have a blessed day

[@TerenceDIY]

Two questions... How is your heat blowing? Secondly, have you replaced your coolant temperature sensor? I had a similar issue on an 08 express van and the temperature sensor was the culprit. Please let me know.

[@mack606]

@@TerenceDIY yes sir I went to AutoZone and replaced it and the heat blows hot when temp gauge is at 210 once it drops just a little right behind the white line that’s right on 210 it blows warm is it possible that coolant temp sensor could be faulty

[@TerenceDIY]

If you have a code scanner, even a cheap one, you could diagnose your temp sensor and or gauge pretty quickly. I would do that so you can find a definite answer. The code scanner will pull the accurate temperature from the ecu/ecm in real time. I'm curious to see would it match up with what the gauge is reading.

[@mack606]

@@TerenceDIY thanks I will definitely try that

[@TerenceDIY]

Let me know what you come up with.

How often do the T connectors at the firewall leak

[@TerenceDIY]

They rarely leak. I only seen this once out of many trucks.

@@TerenceDIY seen coolant under my Yukon and did an inspection and I got a leak at the white T connector I’m going to replace them but not with the quick connect but with the hose straight on the T connectors with a clamp the hose will be stretched just a little bit is that okay or should I just cut a heater host to correct size so it will a lil slack in it
