First check the cooling fans for functionality, also make sure you have enough water put into the radiator otherwise you will overheat the engine. if that doesn't solve the problem, it could be something else that only a mechanic can tell you once he look at it.

How do I know if my head gasket it blown? Why is my car over heating?


to test the head gasket you could do a compression test that will tell you if any cylinders have low compression if you do have low compression this could be a bad valve, bad rings or a bad head gasket. if you can I would do a leak down test on the cylinders this should be able to tell you if you have a bad valve, bad rings or a bad gasket. your car could be over heating if you have air in the cooling system or if the cooling system is bad or if your thermostat is stuck shut.

I have a 2001 nissan sentra 1.8 with 158,000 miles. Problem started a month ago,no heat while idling but when revved up or driving would have heat. Changed thermostat,bled system from bolt above thermostat...


unfortunately these engines are known for this condition and for head gasket failure.with engine cold pressurize cooling system with spark plugs removed.look down into holes with flashlight after about ten minutes.....im betting youll see a puddle of coolant on piston...usually its cyl# 2 or 3.i cant think of any other possibility for system repeatedly airlocking other than a head gasket.good news they are probably one of the easier ones to replace.

Replced pump,thermestat,fan clutch.still overheats when driving


That only leaves 4 possibilites. One radiator cap is worn out, Two hoses collapsing when vehicle heats up, Three water pump has gone bad. Four a blown head gasket.

Most people never replace a rad cap until it actually becomes a problem but its the cheapest of the options. Hoses are easy enough to figure out. Let the vehicle heat up and see if they squeeze shut. Wtaer pump can be easy if you can actually see into your radiator. If you can verify movement of fluid. If its not moving the pump isn't working. There are only 2 ways to verify a head gasket issue. One is steam coming from the exhaust the other is a chemical test you do with the coolant of the vehicle.

Car turns over but does not start. Battery good


If it over heated, could have bad head gasket's, fill radiator with water, crank engine with radiator cap off, if water is push out of radiator while cranking, bad head gaskets', also remove spark plug's, crank engine if any water, bad head gasket, also when spark plug's removed, check for any water on them.If there is any water on plug's, bad head gasket, also could try doing a cylinder compression test, if bad compression, head gasket, no compression, wont start that way.

Over heating/ loss of coolent


If you are not loosing coolant on the ground. You may have a problem of a bad intake manifold gasket or worst a bad head gasket. The two things to look at are coolant in your oil, manifold gasket. Coolant out the exhaust, head gasket.
