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.
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.
Sounds like a blown head gasket or a cracked head. does the car overheat? check for water in the oil, or oil in the radiator.
Bad thermostat, plugged radiator, blown head gasket in order of expense.
low oil low radiatio flued or the thermistat
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.
Blown Head Gasket or Bad Cylinder Head
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.
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.
If its a legitimate knocking then you would want to go with head gasket if its a tapping you would be looking at a valve
Water pump or leak intake gasket.... also check your T-Stat
It will not cause the engine to overheat. You have another problem.
Blown head gasket or bad radiator cap
it could possibly have either a blown head gasket or intake manifold gaskets leaking
Check the lower intake gasket, or the thermostat...
There are many ways that it can overheat. Coolant loss, blown head gasket, stuck thermostat, clogged radiator ar only a few. You would have to consult a mechanic to know for sure why it is overheating.
thermostats problem my car did the same thing when mine went out
i had high lift blades on my mower & it would overheat. i put regular blades on it & problem went away. could be your problem
NO DO NOT DO THIS. A BLOWN HEAD GASKET WILL LEAK ANTIFREEZE. CAUSING THE ENGINE TO OVERHEAT. I AM NOT SURE HOW MUCH IT WILL COST TO BE DONE BY A PROFFESIONAL.
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.
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.
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.
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.
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
