If the smoke is coming from the exhaust then it's coolant. If its not turning over then it could be hydrolocked from a coolant leak.
The coolant leak is pretty cut and dry - you have a leak somewhere. The lukewarm heat (assuming you're referring to the car's heater) could be for a number of reasons. Insufficient coolant could be one of those. Your coolant could be burnt out. It could be a problem with one of your heater hoses. You could have a worn out heater core.
It could be symptomatic of a larger problem. The coolant may not be circulating properly, or the indicator panel or car's computer could be developing trouble.
First thing to do is check the coolant level.MAKE SURE THE ENGINE IS COLD BEFORE REMOVING THE RAD CAP.If the coolant level is low, it is most likely due to a leak.The thermostat might be sticking,or perhaps the electric cooling fan is not turning on when it is supposed to, it is controlled by the vehicle`s computer.Worst case scenario could be a faulty head gasket or a cracked cylinder head. I suppose it could be a circulation problem but I have found this to be rather rare,(water pump problem)
You could possibly have a circulation problem, or a over heating problem. Need more info.
If a car engine stalls when turning, there could be a problem with the power steering pump. There could also be an issue with an emissions control device.
Intake manifold gasket
You could have a partially blocked radiator or a thermostat that is not opening. If neither of THOSE are the problem, you could have a warped head that damaged the head gasket.
If it is an automatic transmission, the cooler in the radiator is most likely leaking into the coolant system.
A bad coolant temperature sensor is one thing that could cause an idling speed problem with a Peugeot 406. There could also be a problem with the idle control valve.
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.
There could be several reasons. Under normal operation, the vehicle will experience this as the coolant heats up and expands into the over flow. A bad water pump, low level of coolant, as well as a clogged radiator could also cause this problem.
It's a coolant system problem. The most popular reason is low coolant. But it could be a leak in a hose, radiator, or gasket. It could also be a bad water pump.
coolant tempure sensor,thermastat
Could be low on coolant or a faulty thermostat.
Head gasket? Low coolant level? Water pump not circulating coolant? Thermostat not opening? Radiator plugged or restricted?
It could be transmission fluid or coolant, or a problem with the catalytic converter.
First and foremost, check your coolant levels. If you have insufficient coolant, you'll get heat but only after a long time. It could be a heater core problem, or a plugged line but low coolant is a common cause. First and foremost, check your coolant levels. If you have insufficient coolant, you may still get heat but only after a long time. It could be a heater core problem, or a plugged line but low coolant is a common cause. There should be a coolant reservoir under the hood, it will have some markings on it indicating hot and cold coolant levels. If that is empty that is a good indicator that you may have low coolant.
my heater doesn't work in my 04 Chevy impala. My coolant levels are correct, and this still does not correct the problem. Could it possibly be the coil in the dash. If not what could problem be?
The first thing is the oxygen censor could be the issue. There could also be a problem with the fuel pump.
It could be that your head gasket is blown.
Could be the thermostat it's stock, replace it.
low coolant could cause this . without some backround ?
Possibly. Under some circumstances it could cause the battery to short out. If the engine has been running hot for long periods, the heat could damage the battery too. It might also be that the engine has internal damage and the starter is having a problem turning it over.
