2008 Nissan Altima (4th Gen.): Water Valve & Thermostat Replacement.
HTML-код
- Опубликовано: 5 окт 2024
- Hello RUclips, Im just uploading a video of a 2008 Nissan Altima, Thermostat and Water valve replacement (Basically two thermostats). I hope this helps someone out there. feel free to ask me any questions.
Video I Was Referencing: • Nissan Altima Thermost...
Tools:
Phillips Head Screw Driver
Flat Head Screw Driver
Spill Free Funnel- www.amazon.com...
Socket Wrench
Socket Wrench Short Extension ( about 2 inches or so)
12mm Socket
12mm Deep Socket
Drain Pan
Radiator Coolant (whatever type and amount your car requires. 50/50 etc.)
such a good video. I would like to help you as well - straight out of the Haynes repair manual for 07-12 Altima: Thermostat and and water control valve housing bolt torque specs are 16 ft-lbs for 4 cyl engines, and 87 in-lbs for 6 cyl engines. According to the manual, 87 in-lbs translates to approximately 15 ft lbs, but is expressed as inch pounds because torque wrenches can be less accurate at smaller values.
Wow Ty I will pin your comment 😇
Clarification - 87in lbs is NOT equivalent to 15ft lbs, I read the manuals disclaimer wrong. It just states that torque values below 15ft lbs are expressed in inch pounds. Do NOT torque thermostat housing bolts down to 15ft lbs if you have a V6 lol
It is 192 in lb
The manual states 16 lbs. for 4 cyl. NOT 60
Great thanks for that information!!
I have a 2008 Nissan Altima, 4cyl. My son & I just watch this vid. & we have NEVER done anything like this before. It looks like he covered everything in this video, "step by step". (which is helpful!) So we are off to be mechanic's for the first time.. I will come back in here & give an update when we are done. (May the Force be with us, lol)
Well, "about" 3hrs later we got it ALL done. there were a few more hoses in the way & kept dropping a few things. But we got it done... Only issue is after we burp it & let it run for a few mins. My car started to overheat Again. & i already changed out the Radiator. So the only thing i can think of is the "Water Pump". But i do want to say this IS the best step by step vid i Have ever seen. thx for the Help.
@@johnseager9791thank you brother 🫵🏼💪🏼. I hope you and your son enjoyed the most important part of it, the bonding time . Love. Yes I would change water pump if you’re over heating. 👌
You did a great job on this.
16-foot pound of torque. That is what I was told.
just a note for anyone replacing the thermostat and water valve on the Nissan Altima 2007, make sure you place the spring part INTO the engine, followed the service manual and this video and my P0128 has been fixed, thanks for upload!
Was just replacing it, and the stock water valve was reversed (the same as shown in this video) although the diagram shows the spring going into the engine. I replaced the same way as stock, the same way as shown in this video...will see how it goes tomorrow....very odd.
So this car basically has 2 thermostats ???
@@brayantheguru 1 thermostat, and 1 water control valve, they have different temperature settings for opening let me know if you need help I have the part number from NAPA, they have a kit for both, and includes the gasket
I mounted the fuse for the amplifiers in exactly the same spot and same hardware on my 09 altima. 😂
I bought the base 2.5 model that didn't even come with a radio because of the price and I wanted to do my own sound system and wheels.
I bought this car new in December of 2008 for $17,500.
Now I'm watching videos on how to fix it.
Thank you dude. Im not sure why your video was so far out in the results when i searched for how to change this.
So far you're the only one who actually did a step by step and didnt skip removing the housings.
Unfortunately im gonna have my mechanic do this job.
Thank you for this video it was very clear. I appreciate the time you took to make it and actually SHOW all the parts.
Your very welcome!
Wow... You are the most patience youtuber I have ever seen . You really went inside the head of viewers.
DrNemea well thank you very much. I tried the best I could . Hopefully this helped you or someone you know
I've been wrenching for a while now and I must say you've made one of the best how to videos I've ever seen it kind of inspired me to start making my own thanks a lot keep up the good work
Needed these words my brother. Thank you
I’ve only changed spark plugs before and thanks to this video I was able to replace my own thermostat! You’ve given me a lot more confidence in future jobs. Thanks for the detailed video , make more please ! Lol
Lanier Williams man that means a lot to hear. This was my first time doing a video on this kinda thing. I will def have some more in future weather it’s this car or another. Thanks for your feed back. I’m glad this video helped you gain some confidence and get the job done. I know it Feels good to know you can handle a task like that, cause I felt that way. Please share this video with anyone else you’d think it would help.
Thank you !!!!! I just saved $250 by doing it myself. AND... the quality of the video and clearness of instructions are great. I would have never considered doing this myself, but your video made it fairly easy. Including going to the store for parts and a breaker bar, the job took only 4 hours. You da man!
Man I love hearing how this video has not only saved ppl money but empowered them To not be scared and take control. Most car work can be scary but I always say with the right instructions anyone can do most maintenance on their own cars. Please SUBSCRIBE as I would like to monetize this video so maybe I can make more in the future. stay safe brother.
This video was amazing! Very clear directions. It took me a while to change mine because the hoses were on there tight!!!!
Thank you for the help.
Not sure who gave you thumbs down but they may be disgruntled mechanics. 😂
Explained very well, I'm getting p0128 code on my altima and after watching your video I'm definitely going to try changing em myself. Thank you
Did this fix your check engine light code p0128? I'm getting the same code but my temp gauge sits at normal operating temp.
@@bigabescanal2799 yes it did, and my temp gauge was at normal also. You definitely should change em, it'll cost you only $25 if you do it yourself.
@@godzwrath so you just changed the two thermostats and not the temp sensor or radiator cap?
Where did you buy the parts? I saw that autozone has the set of thermostats for about 25.
@@bigabescanal2799 that's correct.
Good video but 2 things... 1. On the water control valve you have the thermostat in wrong. THE SPRING GOES INTO THE ENGINE. 2. The torque you said for the bolts was for the V-6. Torque for the 4 cyl. is 16 lbs.
The way he installed it is exactly how it comes out stock from the factory.
Thank you so much
This was the only video that show how to do it step by step and the only Nissan Altima 2008 I could find
Thank you
Thanks for explaining step by step as clear as u could
Jose Eloa your welcome please let me know if you have any questions and feel free to share with anyone you think needs th help
This was great. Thanks. I bought my Nissan and the previous owner had an over heating problem and removed the water control valve and the thermostant. They also must have had a leak because the radiator was full of stop leak and newspaper fibers.
holy crap man!. good thing you took care of that lol, I mean newspaper? wow. And I'm happy this video helped you I really am. Sorry for the late reply been busy for 2018 holidays! I hope that your enjoying yours. Please drop a like and share the video with friends or anyone you think may need help!
Oh my God
Thanks for the video. I saw the other one and it didn't show how to take these apart. Your video was well done. I have a cracked exhaust manifold so I will probably change the thermostats and water control valve while I'm doing that. Two birds with one stone. Thanks for this informative video.
Most def do that bro. previnitive maintenance! my thermostat was throwing a code tat said it was stuck open. so they do wear out eventually . smart man. let me know how it goes. I'm happy my video help!
I appreciate you making this clear and concise video. I'm about to to this and a few other repairs on my moms Altima and trying to get some pregame strategies going.
Jack Daniel let me know how I can help. Thanks for the feedback!
You did a great job with your video. The only thing I would have done was go ahead and remove the engine cover and heat shield for to get at the thermostat a little better. Great job.
Best auto repair video ever!
Awesome job! Excellent explanation! Thank you for not taking any short cuts on the demonstration.
So if you look at the autozone diagram the water control valve should have the spring part loaded into the engine, not the way you have it installed. Since the valve is made to open at lower temperatures it opens the valve sooner to allow the cabin to heat up faster.
Factory torque specs are 16 FOOT/POUNDS for every one of those fasteners you were working with (I don't know where you got 80 Foot/Pounds, maybe you meant Inch/Pounds).....
Great job, now I'm convinced I will not do it myself.
L. Jin awesome! Let me know how it goes
L. Jin
Nice!
👍🏻😂
🚬👌🏻
Me too, this will probably take me 4-6 hrs to do it myself and just don’t have the confidence on the result. I will instead pay Nissan dealer $400 to do the repair.
I know when it’s not worth doing it my self unlike the last successful DIY I did which was change the torque engine mount, that was supper easy.
@@virtudesign it's not that bad just time consuming. There is alot of hoses and bolts to take apart. Looks hard but it's actually pretty easy.
😭
Thanks for the lesson now I'm gona go and fix my 2008 altima same issue 👍
this was a very well done video , it helped me replace the two thermostats. very good
thank you very much, please share with anyone you may think needs to know
!
One of the best car instructional videos!!!
Hey man nice video. Certainly appreciate the time and detail in the step by step. Very clear and easy to follow, lots of good tips. Well done sir!
No need for the music. I'm trying to listen to your very clear instructions but I'm getting a head ache. Your video is entertaining enough because it's informative. No need for a sound track
Thanks for your input but I like the music. And I think I’ll be keeping it in any future videos. 👌🏼❤️😬
Watched like 5 videos before this one that all missed stuff. Thank ya sm 🙏
Absolutely the BEST repair video I've seen yet! Thanks so much bro! Subscribed .
Christopher Bajc much love
BIGGEST THANKS to you for this video!
This was a very informative video. Thank you for taking out the time to help others .
Thanks for the great video! Also nice tips along the way! Will be doing the same on my '07 Altima (195k)
Nice work! Thank you for your time to film this video
Very concise language. Excellent video
Great video. Thanks for taking the time for the ones like me that didn't know
just changed the thermostat and water valve, thank u for this. First time, went well.
It was my pleasure bro, after needing to get this done for a while because my car was throwing a error code on my thermostat (saying it was stuck open). I couldn't find any video online on this model and the one I did find wasn't making me feel confident enough, because at one point that was my only car so I couldn't take a chance and mess it up. anyway when I figured out what the video I was watching was referring too and I did some research I felt I could do it, and I did! so I had to film it for anyone out there that was like me and needed to see the steps in detail before they took there hands too it. Sorry for the long reply. I'm happy this was a help to you, please like and share this with anyone you think may need help.
dude, i am trying to find a video for fixing my code on my nissan altima 2010 and i’m not finding no luck! i don’t know if i need to do exactly what this video explains or what cuz i didn’t know to change a SECOND thermostat.. dealership wants to charge me 700$ lmao. i rather do it myself if i could already do it.. i just need to know, does that 2008 model altima same model as 2010 ? cuz if i have to do this to clear it , i’ll do it myself
the code i’m getting is p0128. what code were you getting when you made this video???
@@Swayyj you need to replace the thermostat and water valve. Its 2 pieces all shown in the video. Autozone gives you the kit. Thanks
Good looking out homie . Spent a hour late night trying to get that bottom 12 but didn't know how to move that metal hose
It’s all good fam. Just please like and share this video to help me out 🙌🏼
Thank you.....and the music is dope !!
much love
Very well explained video! Keep up the hard work bro you make really great content that anyone from a professional mechanic to a DIYer can understand! 💯💯💯💯
I needed these words man thank you
@@MauriceD101 Anytime man, keep doing what you do because you're doing a pretty darn good job at it! 💯
Very informative bro! Thanks a lot! Make more Altima videos. Like changing the 02 sensors on tha catalytic converters
Jose Martinez I will do my best my friend. Please share and like the video so others may find this helpful
Great video bro. I got it done. thanks. also one of the thermostats was installed incorrectly. The spring goes into the engine, I took it out and it was reverse. thanks for clearing that up.
Many thanks brother. and I'm glad I was clear enough to help you figure out a problem with the previous part as well! I hope that you are enjoying your holidays now with this worry off your plate! Please drop a like if you haven't and share this video with anyone you think may need the help!. I want more ppl to find this video if they need help because it still doesn't pop up on google if web searched!
I was worried I installed mine backwards (mine is installed like he did it in the video because that is how the old one was installed). After looking in the FSM (CO-25 on the 2006 Sentra SE-R manual if you want to look it up yourself. I have a 2006 Spec V, but its the same engine and setup.) and doing research including watching youtube videos to see how most people's were originally installed from the factory.... this guy did it right and the FSM illustration is incorrect. If you look at the water control valve housing it has a port in the back. That is the hot water outlet from the cylinder head that is running though the heat core, and of course out to the upper radiator hose (but that only matters when the lower thermostat is open). When the lower temp 177 deg - lower located thermostat opens water obviously flows through the housing out to the upper radiator hose outlet... what this means and what I am getting to is that hot coolant that is freshly exiting the head is flowing through the housing and over the "back" of the water control valve. Once the water control valve opens the coolant from the block enters the water control valve housing and mixes with the coolant from the head and off to the radiator or heater core. This is why they located the temp sender in the water control valve housing right next to the 'back' of the water control valve itself. Hot coolant is always circulating in that location and over the 'back' of the water control valve...even if both thermostats are closed. Sorry this is so long, but there is a lot of confusion about this on the internet and I haven't seen a good explanation, so after figuring this out I figured I would offer one. At the time I didn't understand all this and I just installed mine the way the old one came out because I knew it was never removed before I replaced it, but I am glad that I don't have to go back in there to flip it over because I did it wrong.
@@trssho91 So the official FSM is wrong?
My friend u broke this down ESPN style! Thanks for the video. Peace from NC. 👏🏾
Just finished mines this helped a lot!! (i got a 2010 altima)
Just finished! Thanks for your video
Thank you so much. Your video is great. It really helped me alot.
Thanks for posting this video. I appreciate the amount of detail you put in. Subscribed 👍
virtudesign thank you! I want to make more videos when I get a chance.
This was a real informative video. Thanks!
Boston is easier than the top just did one but your video is true others cut corners on hard part👍
This was nicely done video...thanks for the tips:
Soldier f thank you for the feed back. Please like and share this video!
Good video…very helpful. Thanks!
Excellent presentation. Thanks for posting. Great job!
Excellent How to video.
Much appreciation for making this vid!
Thank you!! 🙏🙏🙏🙏 THANK YOU! this video is prefect man you should do more videos I subscribed just because damn this was a great video
89k views only 289 subs .. WTF I subscribed bro hope you get to 1000 my dude monetarily.
Thx, great job! Very helpful. U boosted my confidence level.
Michael Welch immglade bro let me know how it works out and if you have any questions. Also share this on your Facebook or other social media for me 😬
@@MauriceD101 It all went well! Your video was great. I have 07 Altima, same scenario. I did reuse the one metal gasket, as both thermostats had gaskets on them. Other then that, took my time, followed ur video, no more emissions issues. Thx again, Mike
Michael Welch man that is so awesome, it feels great to know that I have made a piece of work that actually really helps . Take care my friend
what about the water pump? You should make a video on how to change the water pump on the 07 - 12 Nissan Altima 2.5S, that would also be very helpful. Great video - Thanks!!
David G. Santiago hey thank you for the feedback. Please share this with whoever you think maybe need the help and like it so it will pop up on more peoples feeds. I will do my best to get that video out for you ASAP. Will take a a little time as I have a 2 year old but I will get it done for you.
@@MauriceD101 thanks... And will share your video
I just the job wish I saw this video first lol I didn’t see the other screw so I just bent the pipe as much as I could to get some working room and carefully bent it back when I finished.
Julio Garcia hey if it works ok lol. Just be careful doing that in future . Don’t wanna make your job harder and more costly.
Good video MauriceD! Thank you for the clear information.
When. your have 6 or 8 mm bolts I would think torque specs would be in inch lbs, definitely not more than 15 to 20 ft lbs, lucky you didn't break them off, great video
Yea I couldn’t find any information on them. I just cross my finger in this part but lucky I didn’t and I also didn’t have to retighten from leaks or anything either. If you know the specs please feel free to post them for future purposes. Thank you for the feedback ✌🏼✌🏼
Can I use this tutorial for my 2013 Nissan Maxima?
I just did a 2008 nissan altima thermostacts
My adviseb to is leave the metal gasket on as itis just puthe new one if is soft gasket on top of the metal one. If not is gonna leak. And u gonna have to work more
Thanks for the detailed video on this. I had a quick question and I realize there could be more than one answer, when my 2009 Nissan Altima is at idle, my engine starts to overheat, but only at idle, driving it's fine, but stopping for five minutes or more I began to overheat. Any insight on this? I'm definitely gonna try to change the thermostats out. Was wondering if you had any other insight to why this happens.
I’m not an expert , but if I had to guess it sounds like it make be your fan or radiator. When your driving the cool air entering through the grillis probably keeping the engine cool like it’s supposed too and then when you idle there isn’t a consent breeze of cold air entering the system via grill area so the engine is not able to be cooled down. Normally the fan would kick in and keep it cool buy creating cool winds.
Same problem w/ 2013 maxima did you have any luck with this problem??
I have this issue with hummer h3.
Are both thermostats the same part?
Very well done bud.
thanks for the video
Great job very informative thanks
Great vid, keep doing what you do
Yes i got it done, everything went good thanks
so glad to know!
Bernardo Carmenate how long did it take?
Good job
I have an 07 Altima and I don't feel the bolts for getting the heater pipe out. It is so odd. I thought 07-12 models are all pretty much the same, right?
They are there on one top and one on bottom 2 total . Not saying your wrong . Maybe give it a second look and take your time make sure you have located the correct pipe .
Thanks man. I stuck with the heater pipe
I put the thermostat in how you did in the video, but in the instructions it said to put in the opposite way. I tested drove the car and it heated up almost instantly. I’m going to try and put it in the way the instructions say but I just wanted to know your input. I got my thermostat from auto zone. Good video btw.
I’m not sure why you got over heating problem from that. I’ve driven over 10k with mine changed since this video with no problems. Maybe you installed it upside down? Or maybe there could be another problem.
I was worried I installed mine backwards (mine is installed like he did it in the video because that is how the old one was installed). After looking in the FSM (CO-25 on the 2006 Sentra SE-R manual if you want to look it up yourself.

One a side note.... in my experience you should really be using Nissan OE thermostats because they can be finicky about them. You'd be surprised what the dealer charges for parts like this, its not bad at all. I picked up both thermostats, the steel gasket for the housing, replacement o-ring for the steel coolant return line, temp sensor, and a radiator cap and I paid less than $75 for everything. The lower thermostat for example is actually a dual action thermostat and the reduces the flow to the heater core when it opens. I have a KA24DE that a stant thermostat caused a check engine light because the engine didn't warm up as quickly as the computer expected. Also, these cars should warm up very quickly. With their dual thermostat and dual action thermostat configuration thats the point. When both thermostats are closed water mostly only flows from the water pump to the head, to the heater core, then back to the water pump.
@@trssho91 So the official FSM is wrong?
Hello. I have a 2010 Altima 2.5L. My check engine light is on due to a thermostat warning. My engine heats up a little late but not too late. When I took out the thermostat, the top part was completely close and the bottom completely open. What can be the problem? TY
I have a question can I just remplace my thermostat?. My car has been overheating, so do I need remplace both?
Def do both. They are both thermostats basically. One is just called the water control valve, if you are have over heating problems it would be just to change both anyway. Let me know how it goes bro.
I replaced both today and my car work very good. It wasn’t hard to do it. You video helped me a lot.
so no more over heating? awesome! please like and share this video on facebook or other social media, thats all I ask!@@raymundomartinez2141
@@MauriceD101are both the same part...
nice
Great Video I am doing right now the work following your video and I love it, but I can get the heater pipe out, been trying for 3 hours and the thing is stuck, any tips in how to get it out? my hands hurts, I've been using even a flat screw driver and the washer looks like is only bending,but not moving . Helpppppp Please LOL
The heater-pipe feels like your going to break it pulling out but if you have a good grip and your pulling hard enough it will come out. Just make sure your wiggling and pulling too so that you are breaking it loose . The only reason you see me take it apart so easy is because I took them off prerecord . But y’all the holes need some elbow grease.
@@MauriceD101 Thank you much Maurice, you have a new follower starting today , I got it done and just pass smog check and got new tags from DMV this morning , you video made all this come out as planed
I saw another video where they called both parts thermostats. They both do look like thermostats. Are they both totally different parts?
They look similar and they are both refereed too as thermostats but do not confuse them they are two different parts. One is technically the water control valve which is the one located on the side of the engine inside of the manifold
Awesome video gonna do mine thanks
Awesome! let me know if you got it done!
Great video! Got everything finished now I’m getting a check engine light any ideas
Bid Brothers where you getting this before ?
Thank you bro 🙏
Great video thanks! Kind of a dumb question but both thermostats are the same right?
no they are not! and not a dumb question at all. all though they are both 'thermostats" one is call a water control valve and is different then the other one!
Torque for a 2.5L should be 16-20 ft-lbs. Click the link and the diagram is in the reply. I would assume 2007-2012 would be the same based on the diagram on the 2nd link.

I bought a mishimotto thermostat it doesn't fit the bottom thermostat housing is it designed for the top thermostat housing is that why it won't fit are both thermostats the same size?
Great vid. Awesome job and good information.
Thank you for the video. Is there any kind of adhesive I need to add to the gasket that goes on the water inlet or does it seat fine while you remount the housing?
So which is the actual thermostat? Because I saw another video and supposedly the thermostat was on the opposite side of the engine. On the part that you said was the water valve looks like it has a thermostat as well the band the last one you took off it was a thermostat so I'm a little confused. My car started getting hot today which never happened until today it cooled off then shot back up. Please help.
These "thermostats" do not send temperature information, they only react to coolant temperature by opening or closing. There is a different sensor for temperature detection. I also own a Jeep Grand Cherokee and when I replaced the thermostat it also tried to overheat at first but when I slammed on the brakes, my temp gauge dropped to normal. New thermostats act wonky at first I think.
Thank you for this video and take the time to do it. Different question, what do you used to editing your video? Thx
Simple. iMovie 😅
Yeah this is way too much work for a amateur. Got lost immediately. All i did was change my coolant and hope for the best. Not 100% sure if my thermostats are bad, but I did get that P0128 code. The Coolant was pretty dirty though.
You can do this as a amateur. Just take your time . It’s actually simple
thank you for this video
Your very welcome. Please like and share this video
Thank you for the video you did a great job. I would like to do service for my 2012 Altima to change the coolant should I take off the thermostats to flash the system or is not necessary ?. Second how many gallons your car took when you are refill it with the coolant and what brad of coolant have you used? Thank you
Nawfal Yousuf you do not need to take the thermostat part for a flush. And you need to measure what comes out . I tagged a video in my description on how to do a proper flush. But make sure you saving what comes out to measure what you need to replace.
Thanks so much for this video
Love it thanks
So I know it's best to do both but my question is ...do you have to remove water control valve to access and replace thermostat on the front?
Martin Ison no you do not need to.
I followed your video and fixed my car. Thank you. I tried replacing my second car’s thermostat and once I put everything back together and turned on my car, it started shaking a few times and turns off. Do you know why this is happening? I tried redoing everything and it still does this.
Fernando Velasco so the first car it worked and on the second car after you changed it starts to shake now after ? Both altimas ?
It was a great video. I got a question are the 2005 interchange Bull with 2008
Hey just a quick question I changed the front thermostat which seemed busted when I took it off yet the other thermostat wasn't there when I took it off so I just replaced the front one. Did I do wrong? Also when I installed the front one I dont know if I placed the thermostat in with the arrow or the word "Top" pointing up like you stated. The car runs but the fans seems to come on and stay on when driving far distance and after a long ride the temperature goes up and comes back down after about 3 or 4 days of driving..... help!!!!
Ok so first off you need to redo the front thermostat and do it correctly like I have shown in the video. You could be doing some serious damage to your engine. Especially if the fan is running like you say and the temp is going up. That means your engine isn’t being cooled properly and over time this will result in a blown head gasket or cracked engine block. You need to redo the installation correctly and also you said the other one was missing? As in the water control valve on the side of the engine ? Well that doesn’t sound good or right at all. Someone somewhere along the line of your cars life took out the old one for whatever reason and didn’t replace it wit a working one or one at all it seems. So you need to buy a new one and install it . This should fix your problem. Let me know!
