Yes the upper and lower thermostat housings were replaced. The actual installation happens on the second part of this video (Part 2)

mannysadventures says:

did you replace the lower and upper thermostat housing in this video?

vnomous92 says:

Put in the thermostat housing this afternoon. Everything went well. Thanks for the extra c-clip and o-ring. No more leaks!

vnomous92 says:

Thanks for the video! The entire area around the thermostat housing on my wife’s ’03 Explorer has a bunch of white “flakes” everywhere. Other than normal maintenance, this will be the first work done to her motor in almost 186,000 miles. I ordered the housing (PN 013971) last night and looking forward to getting it installed.

Jimmy Lee says:

Thanks for this video, I just replaced mine and all went well…. Word of wisdom for anyone doing this repair. DO NOT LOSE the little clip that hold the sensor in. WOW, my replacement didn’t come with a new one and I dropped it in the engine compartment. No auto stores or hardware stores I went to had one. Luckily after about 40 min of looking I saw the little bugger hiding and got it out with a telescoping magnet!! Other than that, pretty easy repair!

Jimmy Lee says:

This may be a dumb question but do you have to drain all the coolant out before you do this repair?

Bob Diamond says:

This is the first repair of a part, other than lighting, on this Explorer with 160,000 miles on it,.. I saved about $95.00 by buying a new housing, complete with thermostat, through Amazon.com. I put it on myself and saved about $150.00 on labor. I put it back together, tested it for leaks and it seems to be working fine now. It appears that I saved at least $250 and am back on the road; not having to worry about water and anti-freeze loss during July and August.

PromoMotion says:

Be careful! The bolts can snap… I had the same thermostat housing problem. Bought the part on Amazon and attempted to install it myself. Unfortunately all 3 bolts snapped off inside the block, probably due to heat & corrosion from the leaking coolant. I was able to get 2 out using a Micro GrabIt bolt remover, but couldn’t get the third off. Had to tow it to a shop. They drilled it and re-tapped it.

cesar56611 says:

You cant say All american cars are garbage because they use plastic for coolant to run on, as far as I know about 90% of cars on the road use plastic parts on their cooling system

APDTY says:

Sorry to hear about the headache you are having. The system is not designed to work with RTV, if it’s still leaking something must be causing it, usually it is a poor seating surface for the o-ring to sit on (often caused by corrosion pitting). As a last resort you can always try RTV, but I cannot recommend it.

Mark L says:

Informative & helpful but the camera is always to low, sometimes missing the focus of the video. Cheers !

Why are all Amerikan Cars Pieces of SHIT? Plastic Housing? Come on F.O.R.D

JAIME ARTEAGA says:

GOOD VIDEO BUT YOUR CAMERA MEN SHOULD DO A BETTER JOB COS’ I CAN’T SEE WHAT YOU REALLY DO!

jz13able says:

If u pull the whole manifold ur an idiot u can get around it i know cuz i did one yesterday took me 15 minutes

DJ CUTLAS PHILLY says:

good detail….just would have like to have seen more motor

DJ CUTLAS PHILLY says:

yes he did

APDTY says:

Hi, the explorer sport actually uses different part numbers. Feel free to give us a call if you don’t see them on the website for your truck.

Max Lauro says:

APDTY, does this kit work for 2002 Ford Explorer Sport?

APDTY says:

It all depends on your local repair labor rates and how much you pay for the part, to save some money you can purchase the parts by following the link below the video, and then try to find a local shop that will be willing to install parts that you bring in yourself.

haroof says:

APDTY, how much should I pay for this if I don’t feel like doing it myself and want my mechanic to do it for me?

Daniel M. says:

ford sux

jmbowen84 says:

Wtf. U guys didnt say when u pull up the housing a ton of coolant will come gushing out

Corey A says:

I have a 07 and I have replaced this thing almost 3 times.Ford surely was thinking when they decided to make a plastic thermostat housing.I was wondering do they have a different design maybe aftermarket?That will not warp,It seems to happen just about every year after the winter sets in.

pcfd20 says:

Just goes to show the US is following china with cheap made parts.. Went down the crap hole when they started using plastic parts…

APDTY says:

You likely have an air pocket or two in the system, if that’s the case, the system should stabilize itself after a few days of driving, if it doesn’t, you may need to have it rechecked.

CAMDENFUNK says:

I just had my entire thermostat housing replace due to leakage.with a new thermostat but the gage inside the car is acting a little weird,noticed this on the same day of replacement.is it normal? or should I get concerned

APDTY says:

Hi, it sounds like you have a coolant leak from somewhere, but there are so many possible places coolant can leak from, the only thing I can suggest is to have the cooling system pressure tested to find exactly where the leak is coming from.

APDTY says:

Usually if it’s leaking, it is the plastic on the housing that has failed, the plastic lip that holds the o-ring in place gets brittle and breaks, allowing the o-ring to become misaligned, and will then cause a leak. Unfortunately it’s one of those jobs that while you are in there, it’s best to just change it all to avoid future problems.

cjtf says:

If the housing is leaking along the seal, how do you know if you should replace the entire housing and not just the gasket ? I have a small leak somewhere and dont know if I need to buy a gasket and housing and thermostat or just a new gasket !!
There is a big difference in price….

APDTY says:

AutoWizardful is correct,, (about the seal, not about us having no idea what we are doing,, haha,, I guess we can’t win em all 🙂 ). but yes, it is likely your o-ring on the CTS (Coolant Temperature Sensor) that is leaking. When the vehicle is cooled off, pull the sensor out and inspect the o-ring to make sure it isn’t chipped, twisted, or hardened. When you replace the o-ring it is a good idea to lubricate it with some silicone based grease to ensure it seats properly. Thanks

APDTY says:

Thanks for the feedback. I am sorry you do not like our video. As auto technicians ourselves, we try to explain everything so everyone can understand it. The housing may be upside down when we are showing it to you, but luckily there is only one way it can bolt onto the motor 🙂 Please let us know if you have any further questions. Thanks!

AutoWizardful says:

your sensor o-ring is likely damaged or missing, you would need a new sensor as the o-rings are not available separately. avoid this guy…they have no clue what they are doing.

AutoWizardful says:

Video sucks and he is holding housing upside down, avoid this as a how to…obviously don’t know what he is doing…even showed thermostat upside down wow…how can you guys justify this video as a how to….you should be ashamed.

WendzDarKnight08 says:

I have a 2006 ford explorer and the thermostat housing was leaking from the back similar to your video. I got a new one, replaced the old one. Im hearing a steaming sound and when I took a closer look its now leaking from the thermostat sensor area where the C-clip is. Any thoughts on that?

APDTY says:

we have them for sale on our website at apdty.com you can enter your year, make, model, engine size,, then look under the “Thermostat, Housing & Rad. Cap” category.

Jules Pellico says:

whould anyone know where i could get a o ring for the gasket on my 2005 ford explorer

APDTY says:

We replaced both the upper and lower in this housing, as it is not much more expensive to buy both parts and while you are in there, it is a good idea to just replace both.

Sonya Hill Darby says:

Was it the upper or lower replaced? Do I need to replace both?

APDTY says:

Yes the whole housing corrodes, replacing the housing is the only way to fix the leak.

Othniel Yisrael says:

Do you have to replace the thermostat housing to stop the leak or can you just replace the O ring

Erik Olson says:

Thank you for this, I would not have been able to get this far

APDTY says:

The best thing to do is to have it pressure tested, I can think of 3 things that would cause a coolant leak to appear there; From easiest to fix, to worst:
1) Heater Hose or Heater Control valve
2) Lower Intake Manifold Leak
3) Freeze Plug Leaking
Each of these is a drastically different repair, so it’d probably be worth a few bucks to have a shop check it for the leak.

bulll911 says:

Hey guys…sorry took so long, its a 92 ford explorer. I gave it to a family member that needed a vehicle, but they put a radiator stop leak in and has stopped the leak for now.

APDTY says:

Hi Bulll911, What is your year make and model? Maybe we can help you figure out what is going on. Thanks!

bulll911 says:

Hey guys, I am having some coolant slowly dripping down the backside of my bell housing and my manual clutch. Not sure there are any lines back there, and haven’t pressure tested it yet. Any idea??

Jonathan Neal says:

Very Helpful with my 02 explorer thanks guys!!!
