I just finished doing this on my 07 Mazda cx7 took me 5 hours couldn’t take out the clamps for the hoses it was tight af. The belt was difficult too what I did I went under the car put the belt back but the pulley at the top was far out so I used the car jack long pior on a small wrench to pull the pulley up loose the belt and I had to hold the pipe with my foot 🦶 I got up slowly without releasing the belt and finally I got up while holding the pipe with my left foot and I just pull the belt with my middle finger from the top pulley and bam 💥 I was done 😂 took like like an hour to figure that out tho.😂
Thank you very much for posting this vid, have the same problem with p0126 code. Your vid was a great help! Update: Replaced the thermostat with a mazda oem part $58.00 from local dealer, filled with FL22 coolant from mazda oem bought 2 gallons, used 1 1/2 gallon to fill at $25 per gallon, cleared the codes, bled the cooling system, and it has solved both the po126 and the multiple misfire code has not come back!! thanks again for posting this vid helped a lot.
Dude 👍hell yeah , Thanks for posting , thanks for the heads up on on the sizes and details , only problem i had was putting that pinchè belt on , but its on ,,,, and running like a champ , No way was i gonna let my mom pay over 400 bucks to install a $30 part ,,, keep the videos coming on this cx ,
Is this the non turbo model. And where was the ect sensor located? Should I follow the main radiator hose like you said in the beginning of the video??
Was able to remove and replace thermostat without removing the power steering pump. A hose clamp removal tool made it possible to snake out the the clamps.
As far as coolant, I really don't use it. I use distilled water. I am in Houston, maybe dilute it a bit in the winter for that 1 freeze a year we might get. Water handles heat better than coolant. Coolant is for anti-freezing properties
I agree, you are right. Race cars & track bikes use water only a lot of the time & they are racing. I feel it's okay, but you are right on your points! Elements of coolant have higher boiling points than water & protects components over time!
hello matt how much the temp colland in celcius for normal engine running for cx 7 turbo?and fan will auto working at how many celcius ? some cx 7 old doing pararel fan to ac compresor coz automatic dosn t work anymore ...thnks please inform teh temp engine run normal for not overheat in traffic and engine temp normal
Nathan Dean , sorry late response. YES, twice. Once warranty, second time we traded it in. This car is a turd. Pretty fun to drive, but problem after problem. Design problems, not just problems. I guess it's why Mazda discontinued the name CX7!
I don’t know if he says it in this video because I watched a few, but go ahead and buy the plastic radiator drain bolt from your local Mazda dealer before you start this job. Yours will be brittle and you will break it. Double wrench the tensioner. Third power steering pump bolt is behind the pulley on bottom. You will probably only lose about a gallon and a half of coolant. The engine will need to be ran to get the radiator to take all of it. Peak Global Lifetime is a much cheaper alternative to the Mazda FL22. Meets specs.
what does thermostat do to the AC system? I got a cx7 turns out the AC is heating on 3000 RPM and when I stopped the vehicle the AC will get cooled again.. anyone ?
that is interesting & unfortunate! Pretty sure the cooling system can effect the AC system. My Mazda MPV is directly effected by coolant level. It has a pinhole in the radiator that I JB Welded. It SLIGHTLY leaks, but gets low after a month or two & my AC starts to suck when car temp increases.....?? once again, not a pro here. I'll see if I can get better answer or link for you...
So you want heat, but it is cooling instead? or you want cooling but it is heating @ 3000 rpm instead? if it is that you want cooling, but it starts heating then the radiator cooling system can be effecting it! I use my MPV as proof. I have seen some info that your AC compressor can be under-performing until engine rises over the idling speed. Possibly you just need a recharge of your freon, AutoZone used to come out & do it for you if you bought from them... But, all these options; freon, thermostat, coolant are all way cheaper than compressor RR.
BUT, even MORE!! we had AC replaced TWICE!!!!!! once under warranty & the second we just traded it in!!!!!! POS!!!! they said it contaminated somehow, however it was leaking....? sorry it has been a couple years
Matt Reily second one sir, it turns out heat when the vehicle is reaching speed of 80-100km/h or above 3,000 RPM.. but when the car stops the air will be back to normal (cool)
Maybe so, but when you are tightening a engine case bolt on a chromed out Harley or Hayabusa & the craftsman wrench you are using snaps & you scratch the piss out of the chrome clutch cover... on a Saturday... with the owner watching... along with his entire bike crew... you’ll wish you had a snap on wrench, lol. I could go on & on. If you do it everyday for money, get to know your local snap on dealer
Damn it was hard enough just to get the hose back on and clmaped tight enough to not leak let alone get tbe thermostat out without moving the pump, great idea i thinking ill have to do this cause my upper hose os red hot and the thermostat one is cold.@MattReily

GQ-Rod your welcome, I love UA-cam! Figured I better share, I have gotten a lot from other people's repair videos
This video was just what I was looking for. Thanks

Do you have to drain the power steering pump ??
Was able to remove and replace thermostat without removing the power steering pump. A hose clamp removal tool made it possible to snake out the the clamps.
Were you buy it??
where is the temp sensor located?
what type of coolant
did you use
man I just replaced the vtcs on mines took it for a test run and it overheated wtf
How you doing bro I have a quick question I have a 2008 Mazda CX nine would you happen to know where my engine coolant sensor Would be located
na man, I think they are different engines. I have long gotten rid of this turd. good luck tho
hey man i got the belt off but i cant get the pump off is it just the two screws up top?
Looks like you probably already did it, 3 weeks ago, but there are 2 below also. Kind of tricky, in the video...
As far as coolant, I really don't use it. I use distilled water. I am in Houston, maybe dilute it a bit in the winter for that 1 freeze a year we might get. Water handles heat better than coolant. Coolant is for anti-freezing properties

215 - 220F / 104C I think it is pretty standard for all engines, in that area,🥂
@@MattReily thnks for the info i have between 86 degree celsius to 91 c
I changed the same part on my car to it was everything you said and now the ac want hold an charge you ever had that problem
Nathan Dean , sorry late response. YES, twice. Once warranty, second time we traded it in. This car is a turd. Pretty fun to drive, but problem after problem. Design problems, not just problems. I guess it's why Mazda discontinued the name CX7!
Im a do it at home guy myself. Is this possible to do it in 3 hours?
I would say yes. I don't recall it taking too long. But, right tools readily available helps a lot. I didn't use anything fancy but...
turns out I have a cracked head gasket... yay cant wait to punch the guy in the face who sold me it for 6k$ cash
that does suck! car trouble is such a pain in the ass! Mazdas haven't been very good to us....
Hi what is the working temperature of thermostatic
Gustavo Reyes couldn’t tell you, but shouldn’t be getting more than 210*f - 215*f ? Not sure
@@MattReily thanks... seems a lot mine work at 210/217 f but all engine is too hot. I check some thermostatic valve and start to open at 186f

Matt Reily not sure what the cause of it, appreciate your comment sir

Will this cause the car to smoke like a cheech and Chong in a clam bake? Lol
Don It certainly can, the smoke is just of a more, chemical frangrance...
Yeah most definitely wasnt fun replacing
Over priced shit thats what snap on is.
Maybe so, but when you are tightening a engine case bolt on a chromed out Harley or Hayabusa & the craftsman wrench you are using snaps & you scratch the piss out of the chrome clutch cover... on a Saturday... with the owner watching... along with his entire bike crew... you’ll wish you had a snap on wrench, lol.

Doing way too much to replace the thermostat
Not much to it the way that I did it, what light can you shine on the matter?
