Okay! So what I did was cut my car completely off for two days, I drained the radiator by unplugging it, I took the water hose and just let the water flow in and out from the coolant housing under the hood in the right hand corner, I also let the water flow into and out of the radiator, I plugged the radiator back up after just a few clear coats of water flowed through, I filled with 1 1/2 containers of Peak 50/50 Antifreeze/Coolant. I later in the day noticed that one of my fans were out and the other one wouldn't stay on. I ran a kill switch from the inside to the fans, only one is working due to the motor on one of them but I can guarantee that my car hasn't over heated or ran hot since I did this coolant flush. And also when you put the new coolant in make sure that the car is excessively cold. If your fans aren't spinning then that's another reason. I wish you luck.

How do I locate a leak that lets antifreeze and oil mix inside the oil pan?

Most likely a head gasket. The coolant is forced into the oil chambers and mixes. This too leaks into the exhaust gases and burns off as you describe. You usually get oil in the coolant reservoir. This can be checked with a test strip available at automotive supply store. It measures the acidity in the coolant.

How can i tell if i have a blown gasket i cant really tell where water is leaking from but i can kins see it running out what looks like a pan or somthing under like the water pump area under cranshaft and...

Hi, If you see white smoke coming from tail pipe then you will know it is leaking through engine.
I would suggest after you replace head gasket, that you put new radiator fluid (50/50) mix and a new thermostat in. The fluid will keep it from boiling over. Good luck.

White smoke coming out of the tail pipe .

White smoke is caused by water and or antifreeze entering the cylinder...If white smoke is present, check to see if the proper amount of antifreeze is inside the radiator and the overflow bottle. Also check to see if antifreeze has contaminated the engine oil. You can look at the engine oil dipstick, or look at the under side of the engine oil filler cap. If the oil is contaminated with antifreeze, it will have the appearance of a chocolate milkshake. Do not start the engine if the oil is contaminated with antifreeze, as serious internal engine damage can result.
Good luck..i hope this helps.... please rate me a fixya

Engine over heat

This engine could over heat for several reasons. here are a few things to check check and make sure that the radiator fan is working . check and make sure that coolant is filled in radiator check the lower radiator hose it should be hot when vehicle is hot if it NOT then thermostat may be stuck closed and that will be the reason for over heating. If all of the above is good then check for oil and antifreeze mixing. If it is mixing in oil it would look like a milk shake. Look for white smoke from tail pipe.

1. Excessive Pressure in radiator and car over heats
2. Look under oil cap when antifreeze and oil mixes it becomes a cream-ish white like heavy cream almost. It may be under there.
3. White smoke all the time out the tail pipe
4.loosing antifreeze but there is no visible leak.
5. Antifreeze in oil or oil in antifreeze.
