2018+ Jeep Wrangler JL 2.0L Coolant Hose Kit Installation Guide by Mishimoto 

Im assuming you had to bleed the system with vac. Where is the video for that?

I am not trying to troll, here, but I am genuinely curious... 1) Why? What are the reasons for doing this? 2) If there is a distinct advantage and reason (question 1), why would you leave that short piece of OEM hose under the vehicle at the T-junction? Literally, if I want to do this, I want to do it 100%. If the response is that it isn’t necessary, then why replace the hoses at all? The smaller hose and its closer proximity to the hotter components of the engine, is more susceptible to heat soak/heat cycle failure than the larger ones. It certainly wouldn’t add too much more expense to a kit like this to have one 10 inch, 85 degree bend hose and two worm clamps. I know that if I was purchasing it, the peace of mind that this was fully developed to replace all the stock items would be worth the (maybe 10%?) extra. AGAIN, NOT TROLLING, just genuinely curious.

Do you guys by chance know the OEM replacemt part # for the main coolant overflow tank ?

How did you refill coolant on this 2018 jeep wrangler jl, cause this jeep don't have radiator cap also 2019 jeep wrangler jl sport 3.6 does not have drain plug and don't have radiator cap, so on this situation how do you change the coolant and refill on this jeep? Please make a video thanks.
