it could be the sign of a blown head gasket or a cracked cylinder head provided its engine oil in your radiator , if you have an automatic tranmission there is an oil cooler built into the readiator , make sure that its oil or Transmission Fluid before you go making a repair- if in doubt get a reputable shop to diagnose it . on your own usually either the transmission or the engine will loose fluid , whichever one is leaking - also carefully look for signs that the coolant is not going into either the engine or transmission because that is a bigger problem than the oil in the coolant . whatever you find make usee you clean the radiator with a good cleaning product so that your radiator works efficiently , lots of them on the market today but be careful as many vehicles today have aluminum or plastic radiators and the cleaners used on the old copper radiators will turn a plastic/aluminum radiator into a sprinkling can The engine would not need to be replaced unless it has been ruined by the coolant getting into the engine and ruining it . If its not knocking and you dont have low oil pressure youre probably ok . Time is a real enemy on thsse repairs so get right on it

What are causes of overheating on your ford sierra engine?

One common cause is when you need antifreeze fluid for your radiator. Often times, the liquid becomes completely used and that is when your engine heats up, which could further result in a cracked radiator.

The radiator hoses could be cracked, look where they are clamped to the rad. and engine. The radiator itself could be rusted or cracked somewhere.

A hole in the radiator would do that, or a damaged radiator cap. It could be a cracked engine block that is allowing cylinder pressure into the cooling system, pressurizing the water until it breaks through a weak spot in the radiator.


Why would a 1992 Chevrolet Cavalier overheat when the radiator fan motor water pump thermostat and heatercore have been replaced and the system has been flushed?

It could be a head gasket or cracked head. With the engine cold, take the radiator cap off and crank the engine. If the head gasket is bad coolant should shoot out of the radiator. 12 inches to possibly hitting the hood.


Could a cracked radiator make the water go into the oil line and make the oil look milky?

A cracked radiator will NOT put water in the engine and make the oil milky. A bad head gasket WILL put water in the engine and make the oil look milky. That does not neccessarily mean you have a bad engine. Have someone fix or replace the radiator and replace the head gasket. It could be a good engine for a long time yet


Will a car still run if it has a cracked head?

Yes, it will run but the coolant will mix with the oil and eventually destroy the engine. An engine with a cracked head should not be driven until the head is replaced.

Oil in the radiator on any vehicle is a sign that there is a blown head gasket. This includes the E46 318i motor. Oil in the radiator is also a sign that the block is cracked. Either way, it is a major issue that needs to be addressed before the engine quits completely.

The lower radiator hose goes from the bottom of the radiator to the engine block. On the engine side there will be a neck that comes off the block and the radiator hose is attached too it.

You have a bad head gasket(s).

Head gaskets fail when the engine overheats and the head warps.

remove the radiator cap and start engine. if you see foam and bubble, pretty good bet that it's cracked. also look for antifreeze on the oil dipstick.


What is the most likely cause of engine overheating in a 89 Honda Accord LXi?

1- incorrect amount of coolant 2- stuck thermostat If you turn the heater to HOT and run the engine does that reduce the engine temperature a lot? little? If a lot then look at #2. Other reasons for overheating include a worn out fan motor and/or clogged radiator. The original radiators on these cars had plastic tanks which would eventually crack and leak causing a loss of coolant. Check for a greenish colored residue around the top of the radiator. If the radiator is cracked, it must be replaced. If it is clogged, a GOOD radiator shop can clean it and replace the tanks (if they are plastic), or the radiator can be replaced. Cost of replacement is not a lot more than cleaning on these cars, and the confidence of having a NEW radiator is worth a lot.


1994 Honda accord and the radiator was cracked and i replaced it and bled the air out It is now running hot when the car is in idle and it doesn't seem to run hot when i am driving?

Had the same problem on my 1991 accord. Replace the thermostat, gasket, and radiator cap. Also, get a gallon of coolant if your current coolant has been in there for more than three years. The thermostat is in the engine block. Simply drain coolant, remove the radiator hose from the engine - the hose that goes from the bottom of the radiator into the engine. There may also be a small spount that bolts into the block, remove the bolts and there is the old thermostat.


If a 1996 Saturn SL motor was replaced because a head was blown and oil was leaking into the radiator why is oil still leaking into the radiator?

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.
