TJ Cooling Question-Repost
Trying to get Outlook to do what I want. Sorry for the repost if this shows
up in another thread.
I am replacing the thermostat/radiator in my 2000 TJ. I would like to flush
the block to avoid getting any crud in the new rad. Any reason why I should
not backflush from the thermostat housing (minus thermostat), draining from
the lower rad hose, wtih the engine off? Would a strail flush, engine
running, from the lower rad be better? I have well water, and I would rather
not use that to flush...that's why I want to backflush using distilled.
TIA

Re: TJ Cooling Question-Repost
You really should be opening the drain on the block to flush it. The
drain is on the back side under the exhaust.
I think I would pull the bottom hose and the drain and flush it with the
well water to get the crud out, then finish up with distilled water.

Hi Matt,
With any luck there won't be any crud, if you changed it within the
last couple of years. Make a full drain by removing the block plug, and
you'll be able see any sediment, indicating a need to flush.

Re: TJ Cooling Question-Repost
Thanks Mike and Bill, maybe I should pick up my FSM more often. :-)
There's no torque rating for the block drain, any idea what this should be?
Any kind of sealant needed on the block drain?
I've been bad, this is the first change but there's only 32,000 miles on it.
The block passage behind the thermostat housing looks OK.
