Coolant Color
I'm new to jeeps just purchased a 1996 XJ, it's leaking oil and coolant. When I opened the cap on radiator the coolant was a greenish brown color(pic included). Is this normal with old coolant or is oil getting into coolant. I plan on doing a coolant system flush and replacing radiator, upper and lower hoses, water pump, fan clutch, thermostat/ housing, etc... do I have a bigger issue on my hands by the color of the coolant.https://cimg9.ibsrv.net/gimg/www.che...b5b3f95bb3.jpg |
That looks like sediment to me. If you want to know if you've got a cracked head, look at the oil dipstick and also take the oil cap off the valve cover. If you have coolant mixing with the oil, you'll have a milkshake there.
I'd say start by doing a full flush, probably several times until you get clean water coming out the drain plug hole. If that doesn't happen, you may have a clogged radiator. Not uncommon for these or any vehicle for that matter that doesn't get flushed properly. And they are fairly cheap too. |
X2 flush it till you you get clean water then run it for a couple days and see if it needs to be flushed again . I had to flush mine about 4 times before it stayed clean , then I changed the radiator and hoses .

Have fun getting to the radiator drain. In fact, skip it altogether. Place a 5 gallon bucket under the water pump and pull the lower radiator hose off. Pulling the airbox gives you more room to work up top. You might end up taking a bath from underneath. Been there, done that.

Of course, my coolant at the start was a nice clean green - I was doing the flush as routine maintenance since I hadn't done one since getting the Jeep (that and I did the HCV elimination at the same time.). |

Honestly I think this is the best way, I would rather break a five dollar hose than a $200 radiator. Plastic parts get brittle after so many hot-cold cycles.

I have never once opened the drain on the radiator. Like all have said, bad design and expensive if something happens. Pull the lower hose and drain from there.
