Want this question answered?
if you have tansmission cooling lines or oil cooling lines that go into the radiator, the cooler in side might have a hole in it.
The cooling radiator needs to be used to keep the oil from overheating. If the lines are plugged, the engine could be ruined.
it cools oil by circulating it thru an external cooler and works on the same principle as your radiator hot oil flows thru the cooler and is cooled by air thus "oil cooler"

It works just as your radiatior works , only instead of water being pumped thru, its the engine oil being circulated thru to the smaller oil radiator fixed to the main radiator with oil feed and return lines going back to where the oil filter is located. Air cooled porsches ,which have no water cooling at all rely on oil radiators to cool their engines.This method along with airflow directed over the finned alloy parts of the engine have served them well for many years.
If it is red or brown it is the transmission cooler (in the radiator) leaking. If it is milky white, internal engine oil leaking in to the cooling system, head gaskets.
Early beetles (original - not new beetles) are air cooled - they have a large fan, big cooling fins on the cylinders and a ducting system ("tin" to vw nerds) that direct air around the cylinders to cool the engine. Also an oil cooler ( a mini radiator within part of the tin duct system) that the oil circulates thru.
If is oil then you have a bad intake manifold gasket. If it is transmission fluid then the cooling tank in the radiator is bad.
Sometomes it is hard to get all of the oil out of the cooling system. However the place that replaced the engine should flush the cooling system until it is clean. Also if your car has an engine oil cooler , it could be the cooler in the radiator and not have been the engine in the first place.
Some vehicles run oil line through the radiator for cooling, instead of using seperate oil cooler, which just looks like a mini radiator.
no there is not,if its automatic than its the trans cooler
in front of the cooling fan
