Since winter is coming in (or should I say MIGHT come – 71deg in SC today) soon, I figured I would go ahead and drain the water out of the radiator and block, do a good flush (since the water is ORANGE) and refill with 50/50 antifreeze.
This sounds like a fairly simple 1 hr job, and in most cases it would be. Of course, the Jeep was having none of that simple job crap! I started by opening the petcock on the radiator and the one on the block to drain the orange water out. After it was finished draining, I refilled with water and Red Devil(?) radiator flush. I fired her up and went for a 15 min drive up and down the driveway and around the field. I came back and opened up the drains to get rid of the NEW orange water. While it was draining, I replenished what was flowing out with new water. I did this for about 5 minutes, then shut the engine off to let it drain out completely.
Once empty, I filled her back up with water and fired her up. I let her idle until the thermostat opened and it started circulating. The water turned completely ORANGE again! I was out of radiator flush, so I opted for the only other option I had – Super Clean. I added around 6oz to the radiator and headed up the driveway. Halfway up, the Jeep just died – not sputtered and died – just died like you turned the switch off! I rolled backwards to turn around, but didn’t get quite far enough, so I had to push her a little to get her moving back down the drive.
Once back to the shop, I started troubleshooting. I checked for spark at the points – had that, so I went for the carb. I pulled the fuel line at the carb – had pressure where it entered the carb. I removed the filter screen in the carb – it was clean. I pulled the top of the carb off – there was fuel in the bowl. I blew out and cleaned everything I could get to and reassembled – still nothing. I tried starting fluid – NOTHING! I pulled the plugs, cleaned and gapped them – nothing. I sprayed starting fluid again and it sputtered. Let her crank a little bit and she fired up – back in business! I have no idea what happened.
I turned the Jeep around and drained the radiator and engine again. This time when I filled it back up with water and warmed it up, it wasn’t quite as orange. So I drained everything again and refilled/warmed it back up – pretty clear FINALLY!
So, I drained it one last time, then refilled with a gallon of water and a gallon of antifreeze. I started it back up and let it warm up so that I could top it off with antifreeze. Once full, it was the nice transparent green color I was looking for.
It was a long process, but I guess she needed it pretty bad!
