Has anyone else tried to flush their radiator and breake the drain pet??? Apparently its only a 1/4 turn wing nut but when you turn it, it does not drain right away and so one thinks you should turn it more. Now the valve and the wing nut are separated...has anyone else done this and fixed it aside from filling it with JB weld???? Its a $7 part from dodge but how do I get it in there!? For the record, this is the longest 5minute job ever.
Are you sure that you broke it? Once mine was loose it would just spin around. I gave it a slight jiggle/pull to break the seal and the fluid started draining. When it was done draining, I had to push on the plug pretty hard to get it to pick up the threads again. It tightened down with no leaks. Here is the procedure I followed:
1. Start truck and turn on heat to full blast.
2. Shut truck off.
3. Open radiator drain but not the radiator cap. This allowed the overflow bottle to drain.
4. Open radiator cap. Inside of the radiator looked perfectly clean. Just under 5 gallons of coolant drained out. The used coolant looked nearly new.
5. Close radiator drain.
6. Refill radiator with 50/50 distilled water and Zerex G-05. I got a couple of big air bubbles out of the system by just bouncing the front of the truck.
7. Replace radiator cap.
8. Fill overflow bottle to max line.
9. Add coolant to overflow bottle over the next couple of days to adjust level as air is purged from the system.
After seeing how clean everything looked after 106,000 miles and 6+ years, I am pretty impressed with the Zerex G-05 coolant. I just wish the Zerex was easier to find.
