To help anyone out, you dont need to drain coolant, just unbolt the sensor and put ur new on in finger tight fast as u can, it wont even let a cup worth out, easier.

Thanks!!!

[@ramirocastillo2148]

Thanks buddy. Am about to do that.

[@workingguy-OU812]

Just did this job on a 06 4.3L. NOTES: 1.) No coolant needed to be drained. 2.) for my 19mm socket, and 1/2" ratchet, I disconnected the steering shaft to get at the area better (just like I did for spark plugs in that area), 3.) do clean the area with brake cleaner well enough that a quick switch is possible without gunk getting in the way of the threads, 4.) loosen the old sensor to the point where you don't need even a socket on it. Have the new sensor in your dominant hand & near the area, spin the old sensor out with the non-dominant hand, throw the new sensor right back in. Doing it this way I lost less than one ounce of coolant, which was amazing.

I am always super grateful for videos like this and I have learned quite a bit over the years. but my big issue with a Videos like this is that they start in the engine pointing out what the item is but they don’t actually show you how to get there from outside of the truck. So when somebody like me tries to duplicate what you did I spend a whole lotta time staring at the engine trying to figure out where you’re at.

EXCELLENT.. Right and professional way. 2 do it.👍👍👍👍👍👍👍🚘🚘🚘🚘🚘🚘

Can this bad sensor cause surging when idle?

[@marqkirby9837]

If you replace the radiator, should you replace the temp sensor as well??

[@Carlzday]

they aren't cheap...so if you don't need to, don't.... price for the temp sensor on my 2006 chevy avalanche , is 85 bucks with taxes (canada) however, i would change the thermostat...mine was 12 bucks with the seal at napa AP

I have the code P0116 on my trailblazer would this be the cause? The temp gauge seems to be working just fine but the car shakes like it's misfiring

[@TB-nf6bs]

Thanks for the video. I'm having a heck of a time with replacing mine before I can even get off the ground. Inside my engine bay (2000 Chevrolet Silverado 1500 v6 base) my temperature sensor is connected but the wire fell off on the opposite end the part of the wiring where it connects to the top of the engine block mass of wires. I can't find the place where the wires came off from or a diagram with clear indications of the wiring so that I can TRY to splice back on what else can I try before taking it in...?

[@alexflores1299]

I got a problem hope u can help me, I have a 2013 silverado and my high fan is not turning on the fan will work when I get the a/c on, but if I turn off the a/c the fans stop's working, then I remplace all three relay's for a new ones, and is doing the same thing doesn't work, but when I remove the plug from the coolant temp sensor the high speed fan works and if I connect it back stops working. Pls need help

What if the battery is dead on a 07 suburban do you still need to disconnect the battery negative terminal?

[@stevenmiller7731]

Yes it does!

[@elijahlluellen7690]

Do you know the factory resistance of the ECT sensor?

[@nikkorglassman738]

Everything except one really important step. Before you start, disconnect the negative battery terminal. Second there is no mention of Torquing, with a brass fitting you really need to go easy on tightening. On the 08 Silverado it is 15 ft lbs

[@Shanonmcnab576]

Don't need to disconnect the battery if you unplug the sensor.

[@bluemouse5039]

I have a 2008 Silverado V-6, I was driving home one day and the temperature gauge wasn't working, the fans were running at high speed and the info on the dash said engine hot, I pulled over, opened the hood and the engine was not hot to the touch or sound like a engine that has overheated, once I got home I let it sit for a long time restarted and the fans were running at high speed and again the dash said engine hot with temp gauge not moving off cold, so I knew it was something electrical because the engine was stone cold and disconnected my battery for several seconds then reconnected it, this fixed the problem , the gauge was working as normal, no messages of hot engine, and fans only kicked on after driving a while and temp was up, I thought it was a fluke thing since the truck was sitting for over a week, it ran normal for days after , but now it idles rough when cold , I put some injector cleaner in thinking since the truck was not driven for a while the gas in the tank got moisture , the cleaner helped a bit, but still will idle rough as the RPMs go up and down till it warms up , then it will run OK, Is that coolant temp sensor the problem?

Can ambient air temp above 95 degrees mess with your temp sensor and cause a lack of acceleration condition? Even if the temp sensor tests out ok?

[@sonnychornley9457]

Would a bad sensor cause my rad fan to stay on even when my truck is off? I put coolant in but still stays on I'm thinking is this or a fuse??

Will bad temp sensor on my 05 avalanche temp gauge read wrong shows its getting hot but it's not running cool

[@1AAuto]

+Brandon Farmer Thanks for watching! A faulty coolant sensor will typically result in the engine light to come on, and overheat the engine. If you are getting an inaccurate reading it could be another issue. As always we recommend you have the vehicle looked at by a trusty mechanic if you are unable to diagnose the issue yourself! 1aauto.com

[@brandonfarmer7446]

@@1AAuto its not getting hot y light is already on cause I have bad charcoal canister that I disconnected till I get a new one

[@Shanonmcnab576]

@@brandonfarmer7446 my question is if your engine is hot why is your check engine light is not flashing??? A check engine never flashes for a engine coolant temp sensor it stays on. In the vehical manual if your check engine stays on you can drive it till you get it serviced but if it's flashing you immediately have to pull it over, shut it off and call a tow truck or you could have a catastrophic failure. So I doubt the engine coolant temp sensor can really overheat an engine to the point of destroying it.

[@jgarcia10509]

Now my check engine light is on 🤔

[@joehezy]

Trying to mine to go off as well

[@raydraiz1859]

You need to reset the check engine light and you can do that with a check engine tool that you can get from Walmart for 20 bucks OBD reader I think it’s called or at Harbor freight or you can remove your positive battery cable from your battery for I think 10 minutes 20 minutes maybe the most I don’t think it takes that long to reset and then reinstall battery terminal. This will reset the check engine light and all your settings that you have on your radio and probably other things that have personal settings. When I do it it does not reset my Electric seat position one or two for the different riders using the vehicle.
