Did this video help you?

Zan Glenn: So my 03 escape is leaking coolent when the motor get hot and settle down is that the housing on the thermostat

MIKUKIA11: Thank you! I watched the whole thing but I have zero experience but at least I'll know what I'm talking about when I go back to the mechanic. Also, it will be great to mention the prices of the parts or tool you use, just so, again, women like myself would know if we are being cheated by the mechanics. Thanks again!

Sean Thompson: Good video, thanks. Looks like ordering these parts from you and doing it myself could save me about $225.00 wow...

David Fielder: Whoever is recording did a horrible job. Shouldve gotten closer so we can see the things he's actually talking about

I3igmoon: Anyone else notice the cat walking under the truck he is working on? Hope he did not spill any coolant on the ground draining the system. Animals love the taste of coolant.

bfddr0x: Hi, I ordered this kit as I was having this problem. I went to take out the bad thermostat, when I was removing the bolts from the upper housing the back was rounded. I'm having a hell of a time trying to get this bolt out. I've grabbed a bolt extractor socket, but as you know there's little space to get any sort of wrench into a socket to turn it. I've tried with channel locks and a set of small vice rips on the socket, no luck. Any recommendations on how I could get around this to remove the thermostat to install the new one?

Antonio Restrepo: Very informative, but the camera sometimes misses the action. I'm not a skilled mechanic, but with the help of this video, I was able to make the repair and save at least a 100 bucks. Thank you Auto Parts Direct!!.

mvillan666: Not very helpful with the camera 20 feet away.

Auto Parts Direct To You: @AutoWizardful 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!

CAMDENFUNK: 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

Auto Parts Direct To You: @IOWNNU 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.

DJ CUTLAS PHILLY: yes he did

lewis121701: Why are all Amerikan Cars Pieces of crap? Plastic Housing? Come on F.O.R.D

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

Auto Parts Direct To You: @sodarby 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.

vnomous92: 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.

Daniel M.: ford sux

Auto Parts Direct To You: @WendzDarKnight08 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

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

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

Auto Parts Direct To You: 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.

Auto Parts Direct To You: @bulll911 Hi Bulll911, What is your year make and model? Maybe we can help you figure out what is going on. Thanks!

Auto Parts Direct To You: 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.

bulll911: 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??

Bob Diamond RPh: 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.

Auto Parts Direct To You: @bulll911 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.

jz13able: 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

cesar56611: 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

Auto Parts Direct To You: @sidewalkid Check your intake manifold for leaks. Intake Manifold leaks are really common and could possibly be whats causing your spark plugs to get wet.

bulll911: @APDTY 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.

AutoWizardful: 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.

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

AutoWizardful: @WendzDarKnight08 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.

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

DJ CUTLAS PHILLY: good detail....just would have like to have seen more motor

Sonya Hill Darby: Was it the upper or lower replaced? Do I need to replace both?

jmbowen84: Wtf. U guys didnt say when u pull up the housing a ton of coolant will come gushing out

haroof: 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?

pcfd20: Just goes to show the US is following china with cheap made parts.. Went down the crap hole when they started using plastic parts...

WendzDarKnight08: 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?

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

sidewalkid: hey guys i drive a 97 ford crown vic. when ever im holding the brake down lets say at a stoplight the car rumble a bit. the last spark plug next to the antifreeze is wet......could that be the problem?

Auto Parts Direct To You: @BASICS1A1 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.

Auto Parts Direct To You: @CAMDENFUNK 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.

Auto Parts Direct To You: @The777Apostle Yes the whole housing corrodes, replacing the housing is the only way to fix the leak.

Auto Parts Direct To You: @cjtf 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.

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

Jonathan Neal: Very Helpful with my 02 explorer thanks guys!!!

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

vnomous92: Put in the thermostat housing this afternoon. Everything went well. Thanks for the extra c-clip and o-ring. No more leaks!
