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 AnswerIntake 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.
........from........????????
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.
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
The coolant temp. sensor could be bad....or the thermostat could be stuck shut.....there are a few things it could be actually
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
