2008 Nissan Altima (4th Gen.): Water Valve & Thermostat Replacement.

Hello KZbin, 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/gp/product/B00...
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.)

[@brandonwells4772]

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.

[@MauriceD101]

Wow Ty I will pin your comment 😇

[@brandonwells4772]

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

[@machcruiser5592]

It is 192 in lb

[@danhaggerty2473]

The manual states 16 lbs. for 4 cyl. NOT 60

[@hhn2002]

Great thanks for that information!!

[@daveweiland8433]

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.

[@hardkore360]

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!

[@iambigga]

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.

[@brayantheguru]

So this car basically has 2 thermostats ???

[@hardkore360]

@@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

[@Atmarixx]

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.

[@georgeturpin2913]

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.

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.

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).....

[@richardrichard6725]

Very concise language. Excellent video

[@danhaggerty2473]

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.

I want more ppl to find this video if they need help because it still doesn't pop up on google if web searched!

[@trssho91]

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.

[@travisalvarez5194]

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.

[@MauriceD101]

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.

El primero que retiras es el termostato o la válvula?

[@TehBleach15]

Hey! I love the video and how you explain how to take everything apart. I have a 2007 Altima and as of now it is overheating without driving for very long. The radiator is in good shape, but the fan doesn't turn on when the coolant temp goes above 87 degrees celsius. Are either the thermostat/watervalve linked to the fan in some way? and if so which one would I have to troubleshoot/replace? Thanks :)

[@MauriceD101]

Thank you for your compliment, I worked hard to make it as informational as possible. If you having a over heating problem and the the radiator is fine and your not sure what it may be, then I would trouble shoot and change the parts. Someone else wrote on the comments and said they were having a overheating problem too and when they changed the two thermostats the problems went away. Maybe that will be the same for you. Either way it’s a good trouble shoot and good preventive maintance if worst comes to worse .

[@trssho91]

These cars only have one temp sensor, so if you gauge isn't working then change your sensor because the ECU doesn't know to turn on the fans. Also, I'd just change both thermostats as they are not that expensive and either one can cause overheating. The upper thermostat can cause an overheat condition and it won't even register on the gauge if it fails in the right way. You can also have a electrical issue. These are not single speed fans the high speed circuit may not be be working causing the fans to actually turn off when they should be ramping up.
