Radiator Flushing
« on: August 30, 2017, 07:59:15 AM »
Trying to do as much routine maintenance as I can on our Jeep's. Radiator flushing is on my radar. Is it worth installing the hose kit to flush the whole system? Or, is the process of draining the radiator, adding the flush solution with water, running it for a few days, draining that, then adding coolant just as good? From what I've read, it appears the hose flushing is more thurough. Thoughts?

Flushing is typically more effective because you are going in the opposite direction of the flow the water pump drives fluid in, but only if you have a pressurized system to flush with.

I've always done a hose kit for any radiator flushing its a cheap peace of mind.

I do not use the "flush" kits I think cutting a perfectly good hose to install a Plastic  t with 2 more clamps in the mix is just goofy. Just remove one end (or both) of the heater hose and use water pressure from the hose to flush water both directions (keep radiator cap and drain open). U may get a lil more wet from holding the water hose to the radiator hose and the male barb fitting. But you are not cutting anything and it all stays factory.

makes sense too. I'm definitely going the flush route though.

Using the t kit doesn't guarantee the water will back flush since it's an open t the water will just follow the path of least resistance. So a true complete flush may not be accomplished. If you remove a heater hose (engine side) u can force water in both directions by putting the garden hose from the heater hose and the barb the hose came off of back and forth then u can guarantee it gas been completely flushed
