Absolutely the best thermostat replacement video on KZbin. Thanks for the video.

[@drewheller7400]

Honestly thought car repair was far beyond me, but this video has me convinced I can learn this. Thanks guys!

Your vids are always clear and precise. Best vids on the web. Thanks for all your help. John B.

[@macguireferguson1407]

Awesome video! Everyone will always have their own ways of doing things, especially when it comes to vehicle repair, but i definitely like your methods and how clear everything was. Theres always going to be multiple ways of doing things, but i would say that for me, this is one of the best methods I've seen done. It's definitely not a bad idea to drain the rad, since your already replacing the thermostat, i would definitely want to change my coolant as well. Thanks for the video!

honestly so much easier to just remove the throttle body, gives much more room and no need to touch the alternator bolt. Also a great time to clean the throttle body itself.

[@mountainmover777]

Good point! They do have a video for that too, and I can confirm that removing the throttle body made this job much easier. It also frees up room for replacing the temperature sensor or sending unit. Yes I did clean my throttle body as well!

[@vorpalfire]

Great video really saved my butt and made it simple step by step. Too bad my thermostat wasn't the issue lol. Looks like the houseing got chewed up by the last guy to yank it out. Maybe y'all could do some diagnostic videos in the future? Thanks a million.

[@mountainmover777]

I don't suppose you guys sell the bottom radiator cover do you? Mine's gone.. I suppose I'll have to hit a junkyard and hope to find a replacement. These videos are a God send. Saving me so much money and teaching me skills along the way. Love it!

[@patrickphippspa584]

This guy's GREAT! Love to watch his videos! Thanks!

[@TjarkDProductions]

Thought that was Philip Rivers at first lol good video

[@swivelgate]

Great video, I need to change my thermostat and this showed me how and saved me a few bucks also.

[@1AAuto]

+swivelgate Thank you! Glad we could help.

[@swivelgate]

Just a follow up .I took what I learned from this video and today I replaced my Thermostat . Thanks you 1A Auto Parts. If you could would like to see a video on changing Spark Plugs on a Ford Ranger seems the passenger side back plug is hard to get to. Thanks again

[@richardkey4289]

Did my burst thermo.housing a few weeks ago , a couple things that delayed me : Sensor plug has to be clicked into sensor ( mine is a single sensor) before sliding housing into place on engine block , there's no room to do it after . Farthest rearward of the 3 housing bolts must be dropped into its hole before sliding housing into ace on block , there's no room to drop.it in after housing lands on its spot . * I cleaned my engine block with a green kitchen scrub pad piece before installing new thermo housing . Now for the big job, swapping out a burst heater core . Ouch. All this because I let my coolant % get weak all last summer , then a cold spell arrived . Totally preventable . Check your fluids , folks !!! 1 hour of checking could save you huge problems

[@tonetipreviews]

A1 video from 1A. Clear step by step instructions with a list of parts and tools in the description.

[@intrepidsoul9871]

Do you have any similar videos on replacing the thermostat housing for a 2000 Ford Explorer 4.0 or very similar? Additionally, how about replacing the Timing Chain on the same Ford 4.0 ?

[@intrepidsoul9871]

With the engine in the vehicle, of course...

[@ladonnad.steele2470]

you did it just for me...YOU GUYS ARE AWESOME!!!!

[@1AAuto]

+Ladonna Steele Thanks for watching. We're glad to hear that this has helped you out. 1aauto.com?KZbin&CTA%20Comment&ATony

[@eddieflores7613]

This guy is awesome 👏 ! Thank you for doing this !!!!!

[@timin770]

I have a 2000 ranger with a 4.0. All the videos I see show the thermostat mounted vertically but on my engine it looks like the upper radiator house is mounted to a horizontally-mounted thermostat housing. Does that sound correct? (Tech note: this is not the original 4.0 engine. Maybe its from another year??)

[@justiceschenk5392]

this has gotta be the cleanest engine i've ever seen

[@joerandall3686]

Good video but I would never mess with a radiator drain valve unless u want more problems always drain out the lower radiator hose

[@DGill48]

Good idea.....my 2011 had a brittle hard plastic valve with a "hand turn" valve.... could not budge with fingers, started in with channel locks.....then dreamed about replacing entire radiator. Designed to fail I think. Did the hose thing instead

[@gregdavidd]

What about preparation and gasket replacement?

[@expfighter5112]

aww the ranger you are working on is my exact truck a 2003 Ranger, except mine has the 2003 wheels, but the rest is 100% my truck :)

[@Navyguy1990]

You only created more work for yourself by draining the radiator. I just took the hose loose from the thermostat housing and only lost about an ounce of coolant! 🤷🏻‍♂️ Why don’t you put the truck up on blocks, and remove the drivetrain while you’re at it?! There’s concise and then there’s ridiculous! 🙄

[@alexcastro449]

Awesome video, thanks, you are so professional with your videos!!

[@kyndred2008]

ths this helps alot ,great vid

[@richardvaughan9994]

You guys should probably alert people in this video not to open that rad cap if the vehicle is still hot.

[@bulklogan539]

Common sense should tell you that buddy. But then again, MANY UPON MANY people in America are REALLY REALLY REALLY STUPID!!!!!!!!

[@chrisbaker2903]

Dam right.

[@myagrimm4719]

@@bulklogan539 If you're learning about car repair and don't really know yet how the components work, why would that make someone stupid? They just don't know yet.

[@chesterdarville7824]

Can you please tell the size and length bolts for the thermostat housing for a 1998 ford ranger 2.5L. Thank you!

[@FeedThePuppy850]

i fixed my thermostat but i didnt drain the radiator. there was fluid in a part of the hose where the radiator hose goes into the thermostat and there was some where the thermo was but wasnt too bad. appreciate the video

[@1AAuto]

Thanks for checking us out. 1aauto.com +MinderCodyIzBack

[@Jonbass777]

Excellent video! Thank You so much. Now I need to go and do this!

[@mgomez84]

does it matter which way the jiggle valve is facing? on other vehicles it does

[@Alexwhatisit]

Could I follow the same steps to replace the thermostat on a 95 Ford ranger. 2.3L or am I missing how they differ?

[@1AAuto]

+Alex Zarazua It may be a different procedure on your application. We currently do not have an auto repair video for this particular year, make and model. Thank you for asking. 1aauto.com

[@BeeJayBuzz]

Do you have to drain the radiator before doing this?

[@1AAuto]

+Brandy Winkler Yes it is recommended to drain the radiator. 1aauto.com

[@procowboy1722]

That engine bay is clean

[@vindelsalinas9861]

Very good. Thanks

[@jackwoods2891]

Every time I turned the peacock to drain the rad. it entered turned for me, so I remove the bottom hose. And I also changed the spring clip to.

[@mikec0460]

What was your time to bill on this job?

[@slushjoe]

Thank you nice job

[@CRONIKMASTERBATR]

I removed my old thermostat because my truck was over heating after driving all day it would over heat on stop and go traffic after i drove it all day but now after I put the new thermostat in its over heating right away as soon as I start driving it the needle goes up and down a lot what did I do wrong I barely leaked a little coolant so I just added a little water and I made sure the thermostat went in the same way

[@dylanbarger9044]

Did you ever figure out what it was

[@samcohen5705]

Thank you !!!

[@bladder1010]

Good video, but is it just me, or does this job seem a lot harder than you'd think it would be? Thanks, Ford engineers.

[@1AAuto]

+Maximus Minimus Thanks for checking us out! 1AAuto.com

[@tyreetw]

the housing bolt in the back just keeps turning, it will not come out, i already gotten the 2 bolts out in the front, its an easy job, now its super hard to get that bolt out, all it does it turn

[@Nikkk6969]

Just replaced my leaking radiator 2 weeks ago and now my thermostat housing busted a pretty good leak🤣F Fords cheap Chinese plastic parts I got a 1999 V6 Camry everything’s original in it and metal no plastic wish they would be as good as Toyota

[@jasonstrange6945]

what temperature rating is replacement thermo supposed to be?

[@bobbysmith2599]

190 degree on my 99ranger v6

[@joelrobles9092]

You guys rock

[@jonathanhagler7943]

My truck didn't overheat I believe because the thermostat was stuck open. Do I still need to drain and replace coolant?

[@1AAuto]

+Jonathan Hagler If the coolant is old and has not been serviced in a while you may want to.

[@jonathanhagler7943]

Thanks! I'm doing the job today and using this vid as reference. Hopefully it all goes well. Thanks 1A!

[@nealperez9974]

always pro thanks

[@Kylefishgerald]

Would this be the same for a 2001 3.0

[@1AAuto]

+Kyle Fitzgerald It may be a different procedure on your application. We currently do not have an auto repair video for this particular year, make and model. Thank you for asking. 1aauto.com

[@Kylefishgerald]

1A Auto Parts thanks for the reply

[@Rahani11]

Hey guys, not sure if anyone even looks at these comments anymore but, I recently changed the thermostat on my 2008 4L ford ranger and I had to put a massive amount of pressure on it to get to compress so I could get the bolts back in...that to me doesn't sound right....did the parts store give me the wrong thermostat?

[@1AAuto]

+Rahani11 Thanks for checking us out! Unfortunately, without being with the vehicle and examining the part we would not be able to confirm if the incorrect item was provided. If you are concerned the item is incorrect we would suggest having it looked at by a mechanic. Please let us know if you have any further questions!

[@willieolivas7549]

Cool thanks"

[@elmiguelonchevytunnig263]

Excelent

[@Steve-gj1ev]

The actual thermostat area looks tricky and unclear. I guess I'll just have to kinda wing it. My thermostat came with a gasket around the perimeter. I am guessing that's all that's needed
