I have 2012 wrangler rhd. Yes I’m a mail carrier. Water pump went out and took serpentine with it. Changed that, also thermostat and then found crack in radiator. Replaced all of those and she is running to the 3/4 mark on temp gauge. Took it back to the mechanic with a coolest temp sensor code. Replaced it also. She is still running to the hotter side. Mechanic says doesn’t get hot at idle. Help!!!

Are you sure you've got all of the air out of the system? Very neat that you've got a RHD.

These can be a pain to bleed sometimes. Open the rad cap in the morning and verify coolant is right to the top there. I usually have to top off a couple times.......the heat cycles will help bring the air to the top for the most part once it's cooled down.

Ok guys, she is still heating to 3/4 temp. I have bled the system over and over. Have as of date replaced, radiator and cap with red lift tab, water pump, thermostat, coolant temp sensor, oh and now a $500.00 electric fan assembly. Aaaawwww

to be clear, when you open that rad cap in the morning, coolant is right up to the top? the system is full, no air, and you're still overheating? had you observed the fan was not operating which lead you to replacing? if so, had you investigated that being electrical vs. bad fan assembly?

I had a hard time removing all the air. Park your keep on an in cline so the radiator is the higher point and follow this

Only thing I find hard to believe is turning up the heat in that video to "open the core". The core is always flowing whether you are heating or not. Heat is controlled by allowing air to pass through the core into the cab or defrost vents. In the summer a flap simply blocks that airflow but coolant is still flowing through the core.

Thank you I’ll try it today
