Before anyone tries this repair, PLEASE read through the comments carefully because there’s some bad advice being given. You do NOT have to touch the power steering pump, you do NOT have to lift the engine or loosen the motor mount or pull the coolant tank, etc. If you have the right extensions for your 1/4 ratchet you’ll be able to reach the three 8mm screws with no problem.

I found the easiest way is to go through the passenger headlight area as well, do not need to remove a bunch of accessories. Be careful not to crack the heater hose that is attached to the small nipple on the thermostat. OEM is made of plastic (semi flexible) and is brittle from the heat cycles. Very easy to crack and the new replacement line is aluminum (not flexible) and not at all fun to replace.

[@avaairheatingcoolingllp3115]

This video showed me how to replace my thermostat on a 2011 Ford Transit Connect. Thanks for the video!!! AND the engineers who designed this didn't care anything about the repair guy. Very very difficult job. I've got big hands and wow it was a tough job.

[@AltruisticWarrior]

Lol that's Mazda for you. In any case the "Mazda" 2.0 is extremely reliable with proper maintenance. Oh, pop off the spark plug boots periodically and check to see if there's oil around your plugs. The valve cover gaskets tend to fail on these every 100k or so but it's an easy job compared to the thermostat(make sure to use an OEM replacement... same with the motor mount on the passenger side. While it's all a PITA to fix these little things, that's about the only problems these engines have.

[@johnmorgan4368]

Will be doing this job this Friday. Thanks for the video; there are a few amateurs with vids on here who are pulling off the coolant reservoir, getting under the car, pulling off the serpentine belt, and every other lunatic thing.

[@kontrarien5721]

There's almost always a better way. For my brother's 2007 Ion starter, they wanted us to pull off the manifold to get at it. An extension, a U joint, and way less effort and the job was done.

2008 Focus SE 2.0 in USA. I just changed the thermostat NOT removing the power steering pump, headlight, grille, or radiator. This one did not have the sensor. The hoses came off the nipples with much struggle, but I managed. Getting to the 8mm screws was easy with a 1/4" ratchet and extention; and a telescoping magnet so as not to drop the screws.

[@12mak]

I did today as well. was hard but possible. lost a screw though so I went to autozone and found a replacement. Long nose pliers and 90 degree pliers made all the difference

[@bashim05]

Is the thermostat can remove to its housing?

[@12mak]

@@bashim05 What? Your english makes no sense. The black plastic housing has the thermostat inside of it. You can reuse the housing if you only get a new thermostat, but make sure there are no cracks or scratches on the sealing surface and get a new gasket so it does not leak. The thermostat and housing is only 30 dollars from autozone (if you have the model without the coolant temperature sensor in the housing)

Haha sorry for my english! I got your point..

I did get a thermostat code as well . I think the computer was trying to make up for not seeing the right heat on the cylinders ..valve cover is next..

Haha yah just did the valve cover as the plugs were full of oil when i went to replace the overhead cylinder temp sensor since mine runs cold outside of sitting at idle for 5+ minutes. Next... the thermostat 😑

2009 ford focus. Took me 1 1/2 hours to do. Quality lube wanted $750. $250 for part and $500 for labor. Bought the part for $28 and did the labor myself. Took out the front headlight, drained and removed the power steering resolver, and removed the hoses and thermostat. Pretty easy, and I am not a mechanic.

The lay out under the hood on my 2009 is different. the dipstick is in they way, as well as ac lines and the over flow tank is more toward the front of the car. There is no way i can get my hands in there without removing a bunch of stuff. Unfortunately i can't post pics here.

[@outdoorrelaxation5511]

So is it normal for the 2010 focus to keep blowing power steering pumps my fiance has blown 3 of them in 4 years she's on number 4

[@NathanLandman]

Yes what John DeRocha said. You should flush any old power steering fluid out of the system. Additionally, it might be a good idea to get a power steering return line filter. Get one with a metal housing instead of plastic.

[@GeauxNutz89]

So I watched another video as well and it said to bleed the air out of the cooling system, you needed to use a gauge attachment and air compressor( special $130 tool...). Is that not necessary?

[@davidhine2991]

GeauxNutz89 you should be able to raise the front of the car (ramps work well or just park on an incline) take the cap off the coolant tank and let it run for about 10 minutes. It should purge out the air pockets.

[@GeauxNutz89]

David Hine. That's what I ended up doing. It's worked well so far so I'm good. Thanks

[@abinadiflores866]

Does the process change if there's an electric sensor in the thermostat?

[@DeRochaJ]

No the process is the same. The only thing different is you unplug the electrical connector for the sensor.

[@scottwest5126]

[@bluegrasskid]

How do you know whether or not you need one with or without the sensor?

[@makeedmatch4913]

If you locate it you can look and, for the one with the sensor, there is a sensor plug in near the small hose. For the one without the sensor there is not. Its easy to see it if you locate the part on you vehicle and look though.

[@joshuabowling3761]

[@hectortorres8079]

Nope just the headlight and grill. You could take off the serpentine belt and the small rubber hose to the power steering tank to give you a little more wiggle room.

im amazed you could get to it without removing the intake. my mechanic said that's the only way to get to it. and because of that, he "doesn't want to mess with it." so i'm stuck.

you can do it with a 5ish inch socket extension, magnet to not drop the bolts, and some 90 degree long nose pliers and regular long needle nose pliers. you only need to really take off the smaller hose. I took the larger hose from the bottom of the radiator is the way I did it because there is more room to work with.

How do remove the A/C connector you point out at 0:58 in the video? I can seem to remove it. Thanks for the video by the way! Very helpful.

[@12mak]

there is a button on the backside towards the thermostat. you press it and feel the button moving down but it still is hard to pull off, but as long as you press the button it will come off. The button IS PART of the assembly you take off, not part of the casing it plugs in to. also you can also get a long screwdriver through the power steering pulley and press it that way while pulling with your free hand. do not pull by the wires

[@4ozsamurai]

Makla Thanks! I actually pulled up instead of pushing down and it released it immediately. I kept trying to push down using a flathead but couldn’t get it to release until I reached back to the edge of it and lifted. Thanks again for the reply!

[@TheShinyLeaf]

Hi, I have a question. I replaced mine just now but now it leaks. Not from the hoses, but from the housing itself. Does anyone know what is the problem?

[@macker0077]

There is a rubber gasket that goes around the thermostat plastic housing. It may not be properly seated when you attached it to the engine. You'll have to unfortunately remove it and check it out. Also make sure the surfaces on both the engine and thermostat housing are clean.

[@thecoop488]

With my personal experience removing the headlight with the two bolts mounted on top of them and just scooting it over above the engine they will give you better access room to removing the clamps holding down the pipes. I also highly recommend going to a local AutoZone and or O’Reillys and getting a 13 inch through 20 inch socket extension because when reaching through the headlight housing it’ll give you a better access room but do not forget that you also need a corner socket bit. If you are having trouble removing the clamps I highly recommend using WD-40. It adds as a lubricant. But it will take time. And also when you are removing the clamps a 13 inch needle nose pliers will work but if you have the right tool that can clamp around the OEM style clamps then go ahead and use it. It will make life 100% easier. Took me about 2 hours but 6 in all to get parts and also have dinner.

[@Trendyrapslut]

If you pull the coolant tank and pull the 3 front motor mount bolts, take some weight off the mount with a floor jack and a block(to protect the pan)you can move the engine back a few inches, makes it MUCH easier.
