The block drain is the plug to the right of the front cat?Dawn dish soap works very well. Fill system with water and a good healthy squeeze or 2 of dawn. A spill free funnel is handy for this operation. Start and let it run with the funnel on the rad, the trans fluid will float up into the funnel as the dawn breaks it up. It going to take awhile, generally takes 2 or 3 hours. Make sure the heat is set to hot so the core shut off is open. After you drain the funnel a few times and aren't getting any more trans fluid coming up into it, take the rad return hose off at the block. Beware as it will be flowing hot water. Stick a garden hose in the funnel, start the engine and let it run. Turn the hose up enough that the funnel is overflowing, run like this for 30 or so minutes. You should now have a clean cooling system. If you open rad drain, and block drain you will get 95% of the water out, and be ready to fill with coolant.
Agree.Wow 🍀 lucky break for you! Definitely would perform multiple ATF flushes to ensure that nasty coolant is removed.
Perhaps you work at a Honda shop, or an independent?As someone who has probably done over 100 of these, your wasting your time with almost anything but dawn. Drain/fill will take forever and you'll be getting trans fluid in your overflow tank for the next year. If you want to get it all out the first time, a spill free funnel, dawn, and an afternoon will do it.
One a side note, I think we have only had 1 trans not survive a rad/cooler failure, and it had 450k at the time.
It is what they use on those poor birds that get all gooped up after an oil spill. Ironically, Dawn's secret ingredient is petroleum.Dawn dish soap works very well.
We very much appreciate an experienced tech who shares his knowledge. It's not you we have a bone to pick with as much as your corporate taskmasters.
