Will your car overheat if you have a cracked head?
Yes! if you have a cracked head chances are your oil and coolant are mixing together and coolant and or oil is leaking out causing the vehicle to overheat... if you have a cracked head fix it! do not drive the vehicle
Let your mechanic diagnose the cause of the problem and advise you on repairs that are necessary. No one will be able to tell you exactly what's wrong without physically examining the vehicle.
What makes an engine overheat instantly even though thermostat is removed?
Make Sure That Your Fan Is Running For Cooling The Radiator. Put A New Thermostat Back In. It Will Run Hot Without One. The Water Will Not Stay In The Radiator Long Enough To Cool. If This Doesn`t Help, Have a Good Radiator Shop Look At It For You. Also You May Want To Resumit A Question as To What Happened If This Did Not Cure The Problem. Thank You
If Heater core is bad on a 1984 Mazda GLC will car overheat?
Not necessarily. It depends on what you mean by a bad heater core. The core will either be leaking or stopped up. If it is leaking, then it can cause the engine to overheat and the only fix is to replace it. A clogged or plugged heater core can sometimes be fixed by flushing it. You can also temporarily bypass the heater core until you can get it fixed. Just connect the inlet & outlet heater hoses together.
2001 Chevy Malibu engine overheating?
If the coolant level is full change the thermostat if not check for leaks. You gotta be more specific with the question

Why would a 5.7L engine overheat intermittently in a 1989 Suburban after being rebuilt?
I had a 89 k1500 w a 5.7 L eng that had the same prob with out being rebuilt. turned out the head gasket was leaking and the coolent had air in it. the coolent was rust colored from the leak. you might also consider replacing the thermostat first and see if it will solve the problem. good luck
or replace radiator
if the cylinders are bored .060 over the cylinder walls are too thin. this will cause overheating.
Why does the engine overheat when idling and cool down when running hard or uphill?
Defective cooling fan or bad fan relay.
thermostat is more than likely stuck shut from the overheat. Have to be changed.
Will engine overheat if intake manifold gasket is bad?
If it blows in the right place. The exhaust is getting into the water passage which will cause the car to overheat. Probably in just a few minutes. With the engine cold, take the radiator cap off, make sure it is full. start the car. If the head gasket is blown, water will shoot out the cap for a foot or two.
Why is not safe to open the radiator cap when the engine is overheating?
When the cooling system is overheated, the coolant is at pressure. Removing the radiator cap will release the pressure, and allow the coolant to boil, probably splashing you with boiling-hot radiator fluid. Your arms and hands will certainly be burned, and there's a good chance that the boiling coolant will splash your face.
You wouldn't like it if that happens.
What is the solution of the engine overheating?
The solution to engine overheating depends on the underlying cause. Some common causes of engine overheating are low coolant levels a faulty thermostat a broken water pump or a clogged radiator. To determine the cause of the engine overheating you should first check the temperature gauge on the dashboard. If the temperature is rising then the problem is most likely related to the cooling system.
To resolve the issue you can take the following steps:
- Check the coolant reservoir and refill it if necessary.
- Check the thermostat and replace it if it is faulty.
- Check the water pump and replace it if it is broken.
- Check the radiator for any obstructions or clogs and clean them out.
If the cooling system is in good working condition and the engine is still overheating then there may be other issues such as a worn out head gasket a problem with the fuel injectors or a worn out timing belt. In such cases it is best to take the car to a mechanic for further diagnosis and repair.
check the thermostat to see if it is opening properly (you can remove it and place it in a pan of water on the stove and heatthe water until it opens oh yeah don't forget to use a thermometer to find out what temp. it was) you should also check your antifreeze mixture for accurracy(try that first) if none of these work try flushing your heater core to see if it is stopped up
This could be an indication that you do not have enough antifreeze. The car heater will not work when there is no liquid in it. also the car will overheat.
How do you check why your engine is overheating and to see a picture of the engine?
autozone.com is a great sight for repair guides and online manuals.
Will engine overheat if it only has water in it no antifreeze?
Not the day you change over to water, in fact it should cool slightly better.
BUT
Not having the corrosion protection included in Antifreeze will cause the system to be damaged and overheat very soon.
Why would a d-engine get to the point where it almost overheats and then cool down over and over?
Sounds like the thermostat is not opening soon enough. possibly it has been replaced with the wrong one, or it's going bad. replace with the correct one, and see if this corrects your problem. Other things to check. The radiator fan temp switch...
Why is the engine still overheating after you have replaced the water pump radiator and thermostat?
Have flushed complete cooling system replaced water pump radiator thermostat clutch fan added 2gal straight anti freeze then filled to capacity with water and truck is still over heating. What else could possibly be wrong
What will be the reasons for the engine to be overheating on the fiat bravo p reg?
could be many resons worst end a head gasket fault,lack of water,inoperable fan,seized thermostat,air lock in coolant system
