T-fitting flush technique
My 94 already has the t-fitting in the hose, and I'd like to do a coolant flush. Never did it this way before....how do you? I'm assuming you just hook a hose up to it and remove the lower radiator hose and flush away???? Do you run the engine and "heat on" while doing it? Please help me out, have no idea the proper steps.

Yes, you do run the engine with the heater on full blast to do the flush. You drain the existing coolant first, then you run the fresh water through till the fluid runs clear, or 15 minutes have past. The coolant will come out through the radiator cap. You may need to purchase another kit for the hose adapter and any other small parts that are parts of the kit if they are missing.

I recently found out that there's a drain plug on the cylinder block. Does it help to use it during a system flush? I know when I open the drain on the radiator for the first time it was clogged with junk. I'm wondering if junk accumulates at the block plug as well.

It might if you power flush with a compressor, but, do not remove it. Many times it is so rusty, you destroy the plug or threads removing it and the only viable option is to use a rubber plug replacement.

Remove the thermostat? I have neer heard of a need to do that when you power flush. The engine is going to be running during this process, and while the removal of the thermostat has a lot of merrits, the main function of the power flush is to clean the engine passages and heater core. A normal drain and refill can take care of most minor deposits in the radiator itself. The aid products do work as well. Run that through prior to your power flush if there are lots of heav deposits. The solution causes the deposits and gunk to suspend in water, so they can more easily be removed. BTW, never ever use tap water to refill the system. You know that scale buildup in the radiators, the white stuff, thats what happens when you use tap water. Use only distilled or RO water, or buy premixed coolant.
