I'm trying to drain my coolant rather than pull the engine block plug. I read on this forum that you can simply drain the coolant by disconnecting the lower radiator hose.

Where is this hose? I have a 1990 XJ Cherokee. Thanks!

from the front its to your right on the bottom...need a flat head to take it off

To drain, do I disconnect the hose end on the radiator or the hose end that is attached to the engine?

why r u wantin to drain the engine block????

There is a screw cap on the bottom of the passenger side of the radiator to drain it.

to do a proper flush you want to drain the block. There should be a drain valve on the bottom on side of radiator. I would pull the block plug also. You wont flush it properly without doing so. Its a 10mm allen.Dont forget to pull thermostat before flushing.

Yeah and careful with that valve, if it doesn't turn leave it alone, don't use pliers.

i flushed my system a week ago and mine didnt wanna come out so i just undid the bottom hose..

and yes from the radiator.
