I hate to be the bearer of bad news but, the most probable cause would be a blown head gasket. Has the engine ever been overheated at any point? This will usually cause this problem. The mechanic should carefully look over the engine block to make sure there are no cracks in the cylinder walls, and check the cylinder head for cracks and warpage. The head gasket seats between the block and the head. There are 2 heads on your engine. If the block is cracked, then you will need a short block, and recommend rebuilt heads as well. Make sure they look it over really good, and I also recommend a new radiator cap, and thermostat. This is the most common cause of overheating.
it could also be bad intake gaskets on the 3.1, I had the same problem with oil in coolant, so I changed intake gaskets, flushed out system, put in new thermotat that was 3 months ago, and the car is still fine. no more oil in coolant!!Honda Man's Answer
Intake gaskets on the 3.1 and 3.4 GM engines are the primary cause of coolant in the oil (just did my brother's today). He didn't overheat his so the head gaskets were ok. Had to change the oil three times before stopped looking like choclate milk. Used the LIS48500 Push rod tool to make the job easier.
coolant tempure sensor,thermastat
could be many things, most likely it needs oil, needs coolant, or it could just have a faulty thermostat, simple
Could be a problem with the thermostat housing or it's gasket, could be a problem with intake manifold gaskets, could be a problem with heater hoses or the fittings that screw into the manifold.
If it is an automatic transmission, the cooler in the radiator is most likely leaking into the coolant system.
A warning on the dic showing an engine power reduce, indicates that there is an electrical problem with the Chevy Malibu. These issues could be worn or damaged sensors, wiring issues, a weak battery, engine overheating or stored codes that could be causing the warning.
The coolant temp. sensor could be bad....or the thermostat could be stuck shut.....there are a few things it could be actually
Need more info. Engine coolant fan? HVAC fan? What year? What model?
could be core plugs between engine and transmission(freeze plugs)
u need to replace the engine coolant thermostat
My car is is running hot and smoking... i discovered the coolant was low i added new coolant and its pouring out the bottom of my car My car is is running hot and smoking... i discovered the coolant was low i added new coolant and its pouring out the bottom of my car
It will be safe to drive short distance as long as the car does not over heat. You can top up the engine coolant or use water/coolant mixture till you fix the problem which could be leaking hose pipe. leaking radiator or faulty radiator cap
Oil in the radiator indicates a possible severe problem, where coolant could also leak into the oil. Driving an engine in this situation at all could lead to severe engine damage.
Diagnostic error code number 118 with high temperature input on a Audi A4 means that the engine coolant is not running at the right temperature. When the engine is cold, it should be warm, and when the engine is warm, the temperature should be cooler in the engine. The problem could be with the Engine Coolant Temperature sensor or the vehicle could be low on fluid.
The coolant sensor moniters the coolant temperature. A faulty thermostat could cause the engine to run cool.
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
Check your oil and see if coolant has leaked into the engine...A known problem with 3.8L engines are defective intake manifold gaskets that allow coolant into the engine block. Costly repair.
check the water pump
A small amount of water can be condensation, however, if it smells like or contains anti-freeze, you have a major engine problem - possibly a cracked engine block which allows the coolant to seep into the crankcase. It could also be a blown "head gasket" which is a less serious problem, but still a large job to fix. This too could allow coolant to leak into the crankcase in some cars.
If you have coolant on the top of the engine it could be a leaky thermostat housing or a leaking intake gasket.
Could be a problem with the wiring from the computer to the sensor.
There are several possible causes for an engine to run hot. It could be low on coolant. The thermostat could be stuck closed. The engine cooling fan is not coming on. There is a blockage in the water jacket, or a problem with the water pump. It could also be a combination of those problems.
Plugged heater core maybe. Maybe the thermostat. Coolant keeps your engine cool under duress. If the thermostat is stuck open, the engine is staying too cool. Your heat is run off of your engine temperature.
The coolant could have frozen in the radiator. If that happens the coolant in the engine will just get hotter. It could also be the thermostat.
Yes, the 2000 Olds Silouette has an engine oil cooler, as well as a transmission oil cooler for the automatic tranny. The engine oil cooler is built in to the engine oil filter housing. Water/coolant enters from the engine block, circulates around the filter housing and exits through a tube to the lower intake manifold. If an engine starts getting oil in the coolant and coolant in the engine oil, this could very well be the source of the problem. An internal leak.
