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.

HEAD GASKET ! HEAD GASKET! blown head gasket is allowing compression from 1 or more cylinders into the cooling system. you can try cooling system repair tablets that are made by g.m. for this problem. however this likely wont cure the problem. head gasket replacement for a 4.6 caddy costs several thousand . good luck!

Yes, a busted head gasket might stall your car if the gasket causes the car to overheat. This can actually blow the heads and cripple the car completely.

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 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.

Why would the alternator over heat the car?

It will not cause the engine to overheat. You have another problem.

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.
