here's my theory: Either the headgasket has a small leak, headbolts mistorqued, and the high pm combustion pressure leaks into the cooling system, forcing all the coolant into the reserve and out of the bottle. the cooling system has insufficient coolant level, thus overheating.

Why does my car overheat at high speeds?
The potential causes of a car overheating at highway speeds are a stuck thermostat, a restricted radiator, or a kinked hose. ... The fix could be as simple as replacing a radiator hose or your car could require a new radiator altogether depending on which problem you have and how severe that problem is.
Why does my car only overheat when I accelerate quickly or drive hard?
Low coolant is only one reason why engines will overheat. ... Why does my Car only Overheat when I Accelerate Quickly or Drive Hard? Assuming everything is in working order, this typically is because you have an undersized radiator for your application.
Why is my car overheating at higher speeds and when on hills but cools down when driving slower or down hill?
The two most common causes are you're low on coolant or have a faulty thermostat. If you're low and fill it, check the level again as you could have a leak. Other than that you may have a failing water pump.
Can low oil cause overheating?
It's usually noticed if your coolant is low, but low oil can also cause the engine to overheat. This can occur even if your coolant level is fine. If there is too little oil in the engine, it will continue to heat up because it has no opportunity to cool.
Can an air filter cause a car to overheat?
In severe cases, a dirty engine air filter can cause or contribute to overheating. Like poor gas mileage, overheating is attributed to a rich-running engine. ... Whether it's caused by low coolant or a dirty air filter, you shouldn't drive your vehicle if the engine is overheating.
Why does my car temperature go up when I go uphill?
When you're going uphill, the engine has to work harder to get the car hauled to the top - and when going downhill - it doesn't. Hence it heats up more when driving uphill.
What would cause a car to overheat when driving but not idling?
This may be due to a faulty heater blower motor or potentially a bad heater core. ... Engine overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, or a failing coolant fan switch.
Why is my car overheating when the coolant is full?
The primary cause of engine overheating is a lack of coolant. But, if your car is overheating with full coolant, it may be something more severe. Other possibilities include a faulty water pump, a radiator blockage, a stuck thermostat, or even a blown head gasket.
Can too much coolant cause overheating?
If you have too much coolant in your system, it will just flow out of the overflow bottle, but it will not cause over heating. Too much coolant will not cause overheating. But if the ratio of antifreeze is above optimal then the engine will overheat.
How long can a car overheat before damage?
You have around 30 to 60 seconds before you start to do serious damage, such as seized up valves or even pistons, if it reaches maximum hot.
