Check the exhaust while it's running. If it is coming out a whiteish smoke it could be going thru the motor and coming out the exhaust. Try pressurizing the coolant system. It should hold at a steady pressure. If not it's leaking into the motor. Sorry!

Why does oil look milky, not like coffee, kinda dark and thinck?


It definitely sounds like there is moisture in your oil. How long has it been since the oil was changed? Has the car sat very long? Has it overheated?

Hi is there anyway I can clean gunk out of my radiator. I recently had it flushed.its causing me to have loss of a lot of antifreeze/water n my radiator. Its shooting gunk through my thermostat area


Describe the "gunk". Is it kind of milky? Like mousse?
If so, you likely have a blown head gasket, and that's oil in the coolant. That's also where your coolant is going.

Ok,I have a 2002Firebird 3.8 seriesII, V6 coolant/water is coming up from radiator with cap off.


When you change antifreeze an air pocket is created in engine behind thermostat. You must let it run until the thermostat opens. Until then, liquid will boil backfkowing through bottom of radiator.
As for milky look, blown headgasket would cause white foam that if left alone wouldclear up. Otherwise it could be an additive in the fluid such as rust preventative.

Loosing antifreeze possibly into oil


If you had been losing coolant into the oil, you're right, it would be like mayonnaise. It's far more likely that the coolant is being lost through cracked hoses or loose connexions between hoses and the block, heater or radiator etc.

99 cavalier, thick milky coolant in overflow, oil is fine, losing "coolant" but level is not going down


Automatic transmission ? If yes, I'd suspect transmission oil mixing with coolant in radiator.

I have 90 toyota 2.4 liter pickup. Its loosing coolant and dont know where its going. Has new t stat, new radiator,new fan clutch, new water pump. Oil isnt milkie and does not smoke. Help!


i would do a compresstion test. If you cant see it loseing coolant on the ground it has to be in the motor, if the oil not milkie and you dont see smoke. ok fell the radiator up with water and let it get to warmed up dont drive it let it get warm. after it warms up open the hood look at your hoses be careful the coolent/water will be hot. first look at all the hoses see if any are swollen or cracked becareful give the motor little rpm like 2000 rpm's this will put more presher in the coolent system and you should see a leak if there is one lot of time you cant see if its leaking after you drive it some holes are very small if you cant find it let me know and i will have you try something else. theres 2 things there for you to try

Losing antifreeze changed thermostat and resivoir cap


Check you oil for signs of coolant contamination. If coolant is present in the oil, you may have a leaking head gasket or intake manifold gasket. If there is no sign of coolant in the oil, the antifreeze could be leaking past the intake gaskets and into the combustion chamber. It could also be a leak that only shows up when the engine is running, and you are losing the coolant as you drive. This kind of leak is very difficult to locate. You will have to look for signs of antifreeze around the upper and lower intake gasket area with a strong flashlight. Also check for signs of leakage at the upper and lower radiator hose connections and the drain valve at the bottom of the radiator. If you smell antifreeze inside the car, check the carpet for dampness caused by a heater core leak. Sounds like a lot of work, but these mystery leaks as I like to call them, can take repeated inspections before you finally locate them. I hope I have been of some help. Good luck and let me know what you find.
