IF it is leaking you're not going to have high pressure. Coolant is under pressure so it does not boil, which make bubbles, bubbles do not transfer heat to radiator walls where it can be dissipated into the atmosphere. It's the same reason it takes water less time to boil at high altitudes: because there is less pressure.

Not necessarily, if combustion gas is pushing out water from the cooling system it will over heat at normal speeds even when idling.Check thermostat is opening ,radiator, pipes and waterways for blockage,air flow through radiator,fan/water pump belt tention and get a proper service /check over.To find out if the gasket is leaking air into cooling system, fill up by the radiator cap when cool,fill expandtion tank to line, make sure there are no other leaks,run and check again when cool,if the rad is full to the top and tank is on line your gasket is probably not the problem.

In my case, the combustion chamber could be leaked and filled with coolant water and then it turned out white smoke coming out from the exhaust. The coolant level will be lower in the result of overheating.

Will a car overheat immediately or would it only do it occasionally if you have a blown head gasket?

Either. It all depends on the severity of the head gasket leak.

Why does your car overheat as you stop and go?

Some vehicles have higher RPM's (Rotations per minutes) causing them to run at higher temperatures at low speeds. In stop and go situations, you are using low gears at low speeds, causing the engine to work harder. These types of vehicles would be better for high speed commuting where stopping and going frequently is not a problem.

Would blown head gaskets cause your vehicle to overheat as soon as you drive it?

it is possible for heat from combustion to cause an engine to overheat quickly depending on where the gasket is blown, but i would look for a lack of coolant circulation first. if your coolant is not getting out of the motor and into the radiator it will overheat very quickly.

Why would a 1998 Subaru Outback over heat?

these had a head gasket problem - the escaping gas forces coolant out of the engine into the bottle, resulting in overheating. Replacing the radiator cap can help, but not fix, the problem - as will not accelerating hard. Also, it might be the thermostatMy '98 outback had an ongoing overheating problem. It would over heat then take the radiator cap off, and the car would be good. It was undetected by pressure testing, but in the end it was by blown head gasket that caused my car to overheat.

Would a head gasket and thermostat cause similar problems on 2005 chev impala?

A blown head gasket could cause an engine to overheat, just like a bad thermostat in an Impala. One difference is the head gasket will probable leak coolant, either in the cylinders or in the oil.

What will happen if the engine fan does not work on a 2002 Jeep Liberty?

If you do not get the engine fan fixed, you will suffer overheating problems. In the summer, should you take it on long drives, the Jeep will overheat, most likely causing gasket damage to either the valve cover gasket, head gasket, or oil pan gasket. It can also damage the hoses, the connection for the hoses, the thermostat gasket, the thermostat; And that's just for the cooling system. If you allow your vehicle to overheat, you can cause severe internal damage, the worst of which would cause you to have to buy a new engine.

Your 2000 S-10 is overheating . Could a blown intake gasket cause this problem?

I don't think a blown intake gasket would cause it to overheat, Most causes of overheating are: thermostat stuck in closed position; faulty water pump; broken fan blades; loose belt; clogged radiator; radiator cap not holding pressure; blown head gasket; low or no coolant; leaking hoses.

How can you tell if the head gasket is blown on a 1998 Saturn and is there a chance the head gasket is blown if it keeps overheating but otherwise runs perfectly?

The easiest way to see if a head gasket is blown is to check the oil, if it is light brown and milky looking then the head gasket is blown. My 1998 Saturn would always overheat. I had replaced the radiator twice and all of the hoses but it continued to happen. The people at Saturn did not know the problem. I brought it to a raditor place and the replaced the gauge that reads the temperature and fixed the problem. The gauge was reading at a much lower temperature than the car really was so the fan would not turn on to cool down the car causing it to overheat. This might be your problem. There is a chemical that can be added to the coolant that will expose exhaust fumes. The head gasket may be fine, but overheating will endanger it. overheating could also be caused by a bad engine coolant temperature sensor, or a bad thermostat, possibly even a bad PCM. ** Only the top answer to this question actually ANSWERS the question.

Why might a Mazda overheat?

most likely would be a leak in the cooling system or a bad thermostat or a bad water pump or posably a blown head gasket. check your oil if it is foamy and a white creamish coler than its the head gasket
