How to Change Thermostat with Housing Assembly 12-17 Jeep Wrangler

Just remove the thermostat with the hose on. Hold the hose with your left hand, twist the thermostat off with your right. The coolant will stay inside the hose instead of pouring down the front of your engine. 👍🏻

You don’t need to drain the coolant. Just replace what leaks out while doing it.

*EVERYONE!* Look for almost invisible cracks in the goose neck of the MOPAR thermostat housing. It took me *FOREVER* to figure this out! My coolent level was always slowly dropping, but I couldn't figure where or how because there was never any visible sign, just a very faint odor of coolent. (Problem even continued after switching out the oil cooler.) When the check engine light told me to replace the thermostat at the 6-year mark, I found red goo on the thermostat housing dried over almost invisible hairline cracks in the goose neck. (I needed a magnifying glass to see them!) The coolent was slowly leaking out and evaporating before it ever had a chance to drip.

The video was right on the money. Took 30 min tops to change it out. Thanks for the video. Great info.

My original thermostat went out after 9 years. Since then, in the last 6 months I’m about to change it for the third time. Granted one of those times the shop used a non-oem one that was known for failing but the other time it was oem. If the dealership doesn’t warranty this one I’ll just do it myself to save on labor

Thank you SO MUCH for making this! You saved me $225!!!

This is an excellent quality video. Thank you so much for making it available. I will definitely be back for more videos and parts.

You are the best mechanic for me...❤

I’ll be buying the funnel and the hose clamp tool. Great video.

100% appreciative...I have heat again in my 2012 Wrangler!

Thank you for this tutorial! 2013 wrangler

You guys always make great videos. Thanks 😁

I wish all mechanics were this gentleman.

Awesome video. 👍 Now, I feel comfortable changing out my thermostat in my 2017 Rubicon.

Really thorough video, as always. Every time I watch one of your vids I feel confident that I can do the project!

Super helpful! Got it done pretty quickly!

glad to see i’m not the only one that has a hard time with those damn clips lol

didn't need to drain the radiator because my thermostat just craked and all the coolant went out cheap plastic dries and cracks i wish they made more durable parts if you off road these parts will break.

Why was this so over complicated?

Replace with OE Mopar part, don't use cheap auto parts store aftermarket part or you'll be replacing it again

I just did mine and DIDN'T have to do half of that nonsense.

Thanks for the video Is it normal for the fluid to push out of the coolant filler ? I think I might of gone past 10 minutes it started to pour out so I turned the jeep off gonna let it cool down and run it for 5 more mins

Sometimes a PIA to “burp”, pull front of the Jeep on ramps, helps the air pass out more freely.

Excellent video, thanks for sharing 👍🏽

Curious as to why you had to remove the air filter assembly? Did you have to change out the hose and needed access to the back of the radiator?

Thank you for your great videos

REMEMBER if you have OEM anti freeze dont use after market,, they dont get a long and might turn to a jell

Thanks. Love these videos.

Where can I get the 10mm bolts that hold down the throttle body air cleaner hose to the radiator?

What’s antifreeze recommended for jeep Jk 2014? 50/50? Or concentrate?

Thanks for the video. No silicone on the housing?

Great video, thank you.

Just curious why disconnect the battery? And do we have to drain all the coolant?

Mine was leaking so bad that my radiator was empty while my reservoir was full, causing the engine to overheat. The crack was barely visible and I managed to stop 99% of the leak by sealing the crack with gasket maker. Nonetheless I am replacing the housing soon.

Bob is my uncle 🤣

I have a 2015 jeep wrangler sport unlimited its overheating Why driving down the hwy Only and when it's siting it's fine in temp what could it be Needing a Burping or Thermostate changed Hope it's not. Blow head gasket ty let me know what ya think sir?

How to Change Thermostat for a 2013 Jeep Grand Cherokee Laredo thank you

GOOD VIDEO thanks man!

mine is leaking from the aluminum housing behind the thermostat and the block itself. is a common issue?? . again its not between the thermostat and housing itself, its the aluminum housing and block.

Hey I followed your step but now my fan sounds obviously louder than usual. Is this normal , how do I fix?

Stupid question but did you unhook the battery?

The drain cock.... counterclockwise? Mine will turn rather easy clockwise, but stops turning counter. (Dealer replaced the radiator a couple years ago. could the replacement drain cock be threaded opposite?

Shop wanted $500 to do this to my daughter’s jeep. 😂😂😂😂

I change my thermostat, but my upper hose is not really hot after few minute later.. why?? And now dont have heat in my side where i sit in the car

Surprised Dorman does not make an aluminum thermostat housing like they do the oil cooler assembly, for which you can replace only the thermostat and not the entire housing, that fails at an incredible, lawsuit/recall worthy) rate.

Call me crazy, is there a good reason to drain all the antifreeze? I just put in all new fluid after replacing a failed water pump. If it's not necessary, I'd rather pull the hose and just let it drain as little as possible.

Do i have to bleed the thermostat

I am curious about the clamp wrench tool that you used. I can't find it on your website.

how much radiator fluid does it usually take.? More than one jug?

Where is the coolant temperature sensor located

Bob’s my uncle?

What code would this cause?

Doing all that, might as well do a coolant flush.

You have hose clamp pliers but you turn a plastic radiator bleed with a pair of channel locs? Lol

Can just the thermostat be changed in the original housing ? Why change the whole unit ?

Great job I have an 2013 jeep wrangler unlimited JK sahara v6 3.6 automatic How often does jeep need a flush and fill? I bought it from a Dealer ship at 91,000 Now it has almost 98,000 Can you please let me know Thanks do you have a phone number I DON'T have a computer or wifi connection just a smartphone

buy a funnel geez

Better remove that thermostat. That causes OVERHEAT AND WILL SPEND YOU MONEY

You take to long on the dumb stuff like the pretty panels show the tabs don’t need to watch everything man
