I made up some adapters to make radiator flushing easy. Just remove your radiator hoses (upper & lower) and replace them with the adapters, screw on your garden hose, and let it run. They are for loan just PM me arrange pick up.

Will this flush the whole cooling system, or just the radiator?

My set up above is just for the radiator but with the radiator disconnected the rest of the system is easy to flush.
Just did mine the past weekend. Complete drain and flush with the Prestone kit. Your mod looks like a better option, especially for anyone who's just interested in a quick flush of the radiator. I hadn't flushed mine in over three years and I was very happy with the quality of the coolant that came out. It looked fresh -- would never have guessed that it had been three years.

Reviving an old thread. I’m going to flush my coolant system to convert to Toyota Red. I’d like to make my own kit, so I have it at my disposal. Do you have the specs on these adapters? What size radiator hose did you use? What size PVC adapters?
After I clear the coolant system with the hose, I’d like to flush with distilled water. Any suggestions for pressurizing distilled water to run through the system?
Thanks!

My adapter are buried somewhere and with 110° temp Im not looking.
A quick trip to HD with a radiator hose in hand would be my choice.RO water is fine for what your needs are in the end both RO and distilled consist of only H2O molecules just the process is different. My system for changing color is a solid reverse flush of the system including all heater lines and the block drain. Fill with RO water and drive until hot. Then re-drain (including the block) if during the drain I feel there is any antifreeze present I repeat. Finally Toyota red with RO water.

No worries. No need to go looking at 110°.
How do you ensure that you flush the heater lines and heater core too? Slide the interior cabin thermostat to "heat" to open the heater control valve at the firewall?
Why do you use the block drain too? Shouldn't the pressure of the water hose ensure that all of the old coolant is forced out without removing the block drain?

Not hard to pull heater lines fro the best flush and yes you will want to adjust for full heat
By removing the block side drain you will get better drains.

I didn't pull the heater lines. But I did pull the thermostat and did a 30 minute flush. Then cleared out the tap water with compressed air.
