Ford Focus Thermostat Replacement - 2005-2011

[@jessicamcgloin3444]

Is there any easy way to tell if your thermostat has a sensor or not?

[@ScottTheCarTech]

+Jessica McGloin This is the on without the sensor www.carparts.com/details/Ford/Focus/Replacement/Thermostat/2005/REPF318003.html?TID=gglpla&origin=pla&gclid=CNWG0_mZ5tMCFQGQaQod6DcD3g&gclsrc=aw.ds This is the with the sensor www.discountbodyparts.com/catalog/feeds/Ford/Focus/Replacement/Thermostat/2005/REPF318001.html?dbpcid=gglpla

[@jessicamcgloin3444]

I was just wondering what the best way to find out if the one in my car does or doesn't have a sensor without taking anything apart. I want to buy the right one before I start taking the car apart!

[@ScottTheCarTech]

+Jessica McGloin The one with the sensor has wires plugged into it on the driver side. I would try looking at it with a flashlight. If you don't see any wires plugged it takes the one without the sensor

My question exactly! Thank you!

[@Prrrrfectshot]

​Shoulda just taken your headlight out, did the factory thermostat come with the sensor?​@@ScottTheCarTech

[@JohnG1000]

I just replaced my thermostat without removing any other parts . Only disconnected the two wires harnesses that where in the way. Small 1/4 inch ratchet and 6 inch extension , a pair of small needle nose vise grips for the hose clamps and some elbow grease that's it . Took me 45 min start to finish.

Hey my 2017 ford focus is overheating I'm thinking its my thermostat any luck on yours

[@JohnG1000]

@@hectorluna1394 I dont know about 2017 focus but 2010 was easy. But very tight for people with chubby fingers to get wire harness off.

[@henryb.7723]

Tried this on my 2005 Focus and it ended in disaster. I was able to get 2/4 bolts out, but I couldn't even get close to fitting a pliers for the clamps in that small space; let alone well enough to have any kind of good grip. I would definitely recommend just taking the headlight off and going through there. It's not a super easy job, but that's the easiest it's going to get.

[@masonhaas3009]

Thank you

[@c0mbat_m0nkey5]

​​@@henryb.7723 This exact same thing happened to me. I got the three bolts out of there and I had nothing to get at the fourth bolt because there's some kind of hose fitting in the way and it's non-movable. I wasn't about to go through the whole process of taking out the light either. This'll be one of the rare times that I actually will take my car into a shop and let them deal with it. 😑

[@gamer007able]

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.

John Nielsen Thanks for watching!

[@LA_Commander]

Good video. The only parts I would comment on are the choice of thermostat: get a Motorcraft thermostat they don't cost much more and are better in quality to most of the aftermarket brands. You are taking a lot of trouble to get in there so you don't want to repeat the repair over and over. Put an OEM thermostat in there it's worth it. Also, these engines use Motorcraft "gold" coolant. Use either Motorcraft "gold" coolant OR Valvoline Zerez G05 coolant those two are the best ones for this engine. Don't use the green stuff. Also changing out your hoses would not be a bad idea if you have high miles on your car. Since you are already in there might as well put new hoses in too, now you don't have to jack with anything for years.

[@iixxion]

Very helpful! I'm gonna get started on mine in about an hour. Gonna drain the radiator first tho. Also I'm not taking that wheel off! I can reach up there without doing that.

[@paulquagge3432]

Hello Scott, Thanks for sharing, I was able to replace the thermostat on my 2005 focus with your help. The only difference in mine was a hydraulic line coming from below that centered on the lower left power steering bolt. Thanks Again, Paul

[@maryokicki8399]

Does it make any sense that the AC compressor would suddenly not work after having new thermostat installed? check engine light went on. Took it in. Said new thermostat needed. Got it done. Picked up car. AC doesn't go on. Zero problems before then. Great video. Extremely helpful. Thank you.

[@jesusperez-dy5wd]

They must have left the ac plug loose or damaged it in the process the wire plug you disconnect in the video shown is for the AC

[@Johnkb2059]

I change the thermostat on my 05 Ford Focus yesterday it's easier if you remove the pulley from the power steering pump

[@rinr7052]

John Bartholomew did yours have a sensor?

[@Johnkb2059]

@@rinr7052 no did not

[@rinr7052]

John Bartholomew great thanks for the quick reply! 👍

[@henryb.7723]

Removing the pulley would have definitely helped to get that tricky fourth bolt on the power steering pump. Still, I think it's easier to just go through the headlight, but to each their own.

[@MarshalBeard]

Hahahaha, I laughed my ass off when you said "good luck with that!" about the alternator. I just did that last weekend with my step dad and his friend who's a mechanic at a Ford stealership. Took us FOUR HOURS! who the hell designed this car? I looked into it. American company, Mazda Japanese engine, designed in Germany. Now ain't that a nice combo. At least I know the engine will be ok, as for everything else.... As proven, breaks easily (American) and hard to work on (German). What the hell Ford!

[@TheIntruderGaming]

Yeah I had to do mine it literally took me 7 hours

[@TheIntruderGaming]

Mazda designed it by the way

[@MarshalBeard]

@@TheIntruderGaming no Mazda designed the engine, the focus body style was designed in Germany by Ford. But yes, the alternator is a real bitch to get at.

[@ScottTheCarTech]

Indeed

[@michaelszczys8316]

They are not that bad once you have been there and done that. Before that and trying to figure it out can indeed take some time. Right tools as well, tricky ones are 12 point 1/4" wrench for taking the studs out.

I'm trying this now and having a lot of problems with the 4th bolt you're talking about at 4:28. How exactly did you get the bolt out? Did you put the wrench through the wheel or come from the bottom? What kind of wrench did you use?

[@goodxy2002]

Finished today. There's no need to take off the power steering pump. You just need swiveling wrenches to remove the bolts from the thermostat. Undo a couple of the pumps, and you can take it out from the bottom.

“Alternators a little ridiculous” I KNOW! THAT DAMN THING BOUT MADE ME PUSH THE CAR IN THE OCEAN! (Long story short 4 1/2 hours later Ended up taking the alternator off the studs and reversing the studs out of the block and squeezing the alternator out the top of the bay now that was a pain in the ass! I had another buddy do it 5 months before I did on his 06 and he ended up unmounting the whole engine assembly, the front bumper, the exhaust then the radiator and shifting the block forward to get it off

[@kontrarien5721]

Alternator's a pain for sure. You unbolt the lower rear motor mount and there's one specific way that the alternator comes out through the bottom, one specific orientation. Before you find the way, you want to destroy everything. After you find the way, it's in and out no problem.

[@shigjetar]

Replacing the cylinder head temperature sensor cleared the P0128 code for me.

[@iixxion]

On a car that old, 9 times out of 10 it's gonna be a bad thermostat. The only way to know what's broken is to take the parts off and test them or just replace them. The thermostat is under 40 dollars and is a good starting point, since they wear out eventually anyway. It is a metal spring that expands and contracts based on temperature, and over the course of ten years its ability to expand and contract properly will be severely reduced.
