Probably have a leaking transmission cooler in the radiator assembly, this would explain why the two fluids are mixing, replace radiator and flush cooling system, and then have transmission flushed and serviced to remove contaminated coolant from transmission

SOURCE: creamy sludge found in radiator.

Transmission fluid goes through the radiator to cool. The line could be leaking into the radiator as it goes through. Usually at the near the bottom is where the line goes in and comes out the other side.

SOURCE: water reservoir coolant is creamy

There is oil in your coolant reservoir, you may have a big problem, either there is a crack between one of your oil passages in the head or the block and the coolant passage, your head gasket is compromised, or the problem could lie inside the radiator if the vehicle is equipped with an oil cooler.

SOURCE: My Volkswagen polo 1.4, automatic transmission,

take off the highest hose,blank one end and fix a hosepipe to the other,remove the cap on the top of the expansion tank and flush through(this way you will get no airlocks).flush for about 15mins,then reconnect,add anti freeze into the expansion tank,and run engine to hot.check for leaks,all done.
it doesnt matter if a small amount of oil is left in helps if you can use the hot water tap for the hosepipe.ask permission from the wife first.....

SOURCE: Water in oil! Very creamy looking oil,,and

Yes it is a blown head gasket. All of these symptoms are sure signs of a blown head gasket. The only other thing that it can possibly be is a cracked head or cylinder. But 99 times out of 100 it is just a blown head gasket.

97 mercury mountaineering has oil in the radiator and coulant. Help please!

OK, lets figure out what's happening here. You are seeing "oil" in the radiator and coolant. Chances are it is not engine oil. The inly way engine oil can get into a radiator would be if a head gasket was blown. Even then, oil at those locations is not under as much pressure as the coolant is, so when a head gasket blows, what usually happens id that the coolant ends up in the motor oil and oil pan. Verify this by looking at the dipstick to see if it is extremely full. The oil could look like choclate milk. Also, open the oil filler cap and look for signs of chocolate brown goop. I'm betting you won't find that. This is good, but also bad. What you probably have in you coolant is transmission fluid. The transmission oil is circulated through a cooler located inside the radiator. If this cracks or breaks the transmission oil can leak into the coolant. However, at different times the transmission oil and the coolant are at odd with one another pressure-wise. This means that if you have transmission oil in the coolant, you probably have coolant in the transmission oil. This is very very bad, You will need to have the transmission serviced and possible overhauled to repair the damage. You will also need to flush the trans oil from the coolant system. This will require you to replace the radiator, ALL HOSES as well. Coolant hoses do not play well with transmission fluid . The inside of the hose sort of melts and gets real soft and gooey. Changing the hoses and radiator and flushing the motor should work once the transmissionhas been serviced.

I have Mercedes Benz sprinter 210td 1998 170000 miles done,I got oil in radiator,engine not smoking,no water in exhaust,no over heating no creamy from oil cap,I change oil after 3000to4000miles,engine...

Consider if it is engine oil or transmission oil or power steering oil. Transmission oil or power steering oil would indicate a bad radiator. Engine oil could be a bad radiator also if the radiator includes an engine oil cooler ("extra cooling") but usually indicates an intake or head gasket leaking.

Water reservoir coolant is creamy looking... no water in oil... maybe oil in coolant system

There is oil in your coolant reservoir, you may have a big problem, either there is a crack between one of your oil passages in the head or the block and the coolant passage, your head gasket is compromised, or the problem could lie inside the radiator if the vehicle is equipped with an oil cooler.

check the color of the oil. if it is white or yellowish you have water in oil which usually indicates a a blown head gasket
check color of radiater coolant for same.if white or creamy/oily you have oil in coolant which usually indicates cracked engine block

The coolant jug has a creamy tan color fluid in it

that means trans fluid or engine oil is getting into cooant system. Not good. Either a leaky trans cooler in the radiator or a blown head gasket. Hope it's the trans cooler

Engine overheats and I've changed the water pump already along with the thermostat. What could be the problem?

many things can cause an engine to over heat
Look for any collasped water coolant hose. That will cause overheating'
If the inside of the engines oil cap looks to have a creamy filling in it that will be from coolant mixing with the engine oil. Head gasket leak and can cause overheating
A clogged up heater core or radiator can cause overheating
A loose or worn seal on the radiator fill cap can cause overheating as well

Radiator fluid leaking, not from radiator or hoses going into engine block. Comes out from above transmission pan.

If the leak is back there? sounds like an intake gasket or head gasket if you ruled out the hoses

Transmission oil in coolant?

Trans fluid can get into radiator by the trans cooler built into radiator side, automatics...
Engine oil can come thru cracked block, head gaskets

Which oil is it? Either way it needs to be fixed.

Typically with automatic trans they can overheat and cause engine temp issues, because they cool thru the radiator using an in tank cooler along side.
IF you overheat the trans you CAN overheat engine
IF you overheat the engine you CAN overheat the trans
