3.6 JL Cooling Flush

[PMyers21]

Whats the best way to flush the coolant on the
3.6 motor?

With this motor/radiator not having a cap vs the previous years I'm not finding any videos/tutorials that best shows how to do it.

Thanks

Drain the system. You can pull the lower radiator hose and get most of it. The block has some allen pipe plugs too. That will get a little more of it, but they are difficult to get to. If you have the right fender off, you can get to one on that side with an extension and allen ball driver. I think it was 10mm. Catch as much of the anti-freeze as possible, put it in jugs and dispose of it at the local hazardous waste depot. The stuff is nasty for animals that may drink it. Causes blindness in severe cases. Bad for people too.

Fill with a garden hose, run it, drain it, repeat. Close all drains, dump in the flush concentrate, fill with a garden hose. Drive it for at least a few hours. I've left it in for a day or two or three while running around town. Drain, fill with hose, drive a little bit or just run it. Drain. Fill with coolant mixture.
