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. 👍🏻
*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.
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

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.
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
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.
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?
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.
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?
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.
most come as one unit and are pretty inexpensive. I think the plastic starts to warp over time too so it's easier to do them both at the same time. I am on my second one after 114k miles
Great job I have an 2013 jeep wrangler unlimited JK sahara v6 3.6 automatic How often does jeep need a flush and fill?
