Hi All,
I'm trying to flush the cooling system on a '99 4.0 OHV and first drained the coolant on a cool engine. Rather disgusting:
Nasty stuff. I then removed the thermostat, threw a bottle of Prestone flush + distilled water in there, let it idle with the heat maxed and drained again:
Not much difference. I did a 3rd flush with just distilled water, (again, still no thermostat and up to operating temp with cabin heat on):
Clearly, a lack of progress. I've since done a 4th flush too. The first flush had a lot more sediment and color was darker, (only because I can compare side by side), but even this 4th or 5th flush (with the peacock open), is still pretty nasty. The consistency of each flush is definitely more water-like so I'm not worried about oil contamination, but does anyone have any ideas if this is normal neglect or something else going on? I see no signs of leakage but I'm concerned the sediment I keep pulling might be one of those radiator sealers:
At this point, I think I've gone through about 8 gallons of distilled water. I'll keep going to do it right, but is there light at the end of the tunnel or should I sell this stuff to neighborhood kids?
