SOURCE: 92 mx3 overheating, no heat inside car??

WHen a car overheats its alwasys one of these problems,

  • thermostat failing in the closed position.
  • the fan not working properly.
  • radiator semi clogged.
  • the water pump would cause this too but usually you will see leaking from the pump itself.
  • low coolant, but it looks like you have checked that.

SOURCE: engine runs but has steam coming out of exhaust pipe

water inside pistons increases compression, You do not have bad piston rings and not burn out intake or exhaust valves, your compression is fine, but You have a blown Head Gasket or a crack for sure

SOURCE: Overheated, now won't start

I would pull the plugs and check them for the presence of water beads. Any time an engine overheats severely, there is a good chance of having a blown head gasket and if this happens, when cooling, coolant can be sucked past the breach into one or more cylinders.

Yes, this is most likely a thermostat problem.

As a basic explanation, the thermostat is the device which separates the hot coolant in the engine block from the cool coolant in your radiator. If it gets stuck closed, your radiator coolant will remain at near room temperature, while the coolant in your block (which is what your gauge reads) does not circulate and will skyrocket in temperature.

SOURCE: 2003 Protege 5 overheating on long runs.

I just replaced the radiator and thermostat on my 03. The radiator was defective (corroded) on the lip where the cap seals. This allowed coolant to be spat out. The thermostat was also sticking closed after new radiator and this caused overheating. Replace both while in there for under $100 if doing it yourself.

88 dodge chadow,overheating and no heat


How long has it been going on? You need to check if you have a bad head gasket. A compression test of the cylinders would tell you. Not saying that's what it is, but that can be a cause of overheating. And it can also be an expensive result of prolonged overheating. That's why mechanics caution against running an overheating engine. If you find the head gasket is good, it will give you great peace of mind, knowing the Shadow's engine warrants a few more dollars in repairs. Compared to the cost of a new head gasket and having the head checked for straightness and for cracks, other repairs for overheating is minimal.
First check the coolant level and keep it full. It could be a worn water pump. Feel for pressure behind the coolant when you squeeze the upper radiator hose for a second or two. The engine needs to be warmed up and running, so the thermostat is open. Try to squeeze the hose closed, then let off and feel for a surge of coolant, and watch the coolant in the radiator for pressure pushing coolant on through the radiator. Kind of a rough test if pump is circulating coolant. You might also try a new thermostat. They are cheap and easy to replace. Clean the outside of the radiator of leaves or dirt. It should be checked for blockage. When upper hose is hot, the lower hose should also be hot or quite warm, just not as hot as the upper hose. If it is, radiator seems not blocked.
Don't worry about having no heat at this time. When the overheating is solved, and coolant level is full, the heater will return.

1999 Beetle Motor Overheating, Radiator is cool


sounds like the radiator might b clogged not allowing coolant to flow. remove both radiator hoses and insert a garden hose and see how much water comes out the bottom..if it flows freely then u have a blockage somewhere not allowing coolant to flow... if the hoses are rock hard when car is running and overheating then u have a cracked head and will have to change it with a new one.

My car keep over heating


Some things to look for if your car is overheating: THermostat stuck in the closed position, cracked head, blown head gasket, leak in radiator, punctured hose, low coolant, cracked block.

Examine the cooling system for obvious leaks in any hoses or parts of the radiator. Let the car run until hot and check the upper and lower hoses. They should both be hot and firm to the touch when the thermostat opens. If the top one is hot and the bottom one is cool and flexible then coolant isn't flowing through the system which most likely is a stuck thermostat. If the coolant level is low you have a leak spomewhere in the system. Have someone pressure test the system if you can't do it yourself. Good luck!

2002 malibu runs hot.


Sounds like you have a faulty head gasket or maybe a cracked head.This can cause overheating and the check engine light to come on.The code for the o2 sensor is probably caused by coolant getting into the exhaust system and coating the sensor.The coolant fan may work but it cannot remove enough heat from the rad to make the engine cool off.Try some engine coolant stop leak to see if it will help.This maybe only a temperary fix.Let me know if you need more.MOE

Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

There's definitely a leak in your coolant system. It could be your reservoir, hoses, rad, waterpump.... you could use a black light and try to trace where the leak is....
