Thermostat Housing Replace and Bleeding Air from Cooling System - 2015 Jeep Wrangler JK 3.6L

[youtube https://www.youtube.com/watch?v=k4XEUc8fdRg&w=640&h=360]

It's time to take care of that leak! I wanted to do this before the Moab trip, and I'm running out of time. So, today was the day! In this video, I change out my thermostat and housing assembly. I didn't drain the radiator for this, and then I show how I bled the air out of the cooling system with help of a spillproof funnel.

Here are the parts I mentioned:

Here's what MY manual says about the coolant I need:

MS-12106 OAT (MS-90032)

The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recommended.
Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant
selection.

MAKE SURE YOU KNOW WHICH COOLANT YOUR SPECIFIC YEAR NEEDS. It's confusing I know. Check your owners manual!

  3. I don't blame you for not draining the radiator. I flushed my system before my Utah trip and the petcock is a major pain to access.

    Radiator cracks as re pretty common on this year. Was covered under warranty. The thermostat housing is another common failure item... Just not sure why...

  10. In the words of jeep service employees "its a jeep, its suppose to do that!!"

    yeah just like the engine is suppose to consume a qt of oil every 1000 miles. Unreal

  11. Question: Did you wait for the engine to cool down before you took off the funnel?

    No... just turned off the engine and pulled it right off. There is no pressure build up in the same way you'd have with the regular cap. The coolant is hot... but other than that, it's no issue to pull it right off.

  15. You might consider doing a follow up on coolants for JKs. For anyone that was casually listening in, they may hear that you're taking a 50/50 mix to Moab. Despite being pre-diluted, the Mopar coolant is not the same as off-the-shelf 50/50 coolants. Moreover, the correct coolant for a JK changed between the 2012 and 2013 models. Using the wrong coolant will at best cause it to gel and can seriously damage the engine. WayALife has a good write up o it, and most local Jeep dealers keep coolant in stock (at least for later model JKs and JLs). https://wayalife.com/showthread.php/13239-ATTENTION-Know-Your-Jeep-JK-Wrangler-Coolants-and-Save-Your-Engine!
