Hi guys, I'm going to do a coolant flush on my 150 series diesel prado. I've read other threads about it, like this one with attached diagrams. I just want to confirm I've properly located the engine coolant drain cock because it's hard enough to reach in there and I don't want to remove the wrong nut! See picture taken through the left wheel arch , I've circled what I think is the drain plug in red and it looks like the coolant will actually come out the green circled attachment. Is this correct?
Also, are there any comments on my procedure:
1. Add Nulon radiator flush to coolant reservoir and drive around for 20 min. with heater on hot
2. Open radiator drain plug
3. Open engine drain plug
4. After all coolant has been drained, put both plugs back in place
5. Refill distilled water into coolant reservoir and run engine for ~ 10min to circulate, then repeat steps 2 - 4. Now the system should be clean and empty.
6. Refill with concentrated coolant & distilled water to required level
