Sunbird GT 3.1 V6 overheats at speeds of 110kmh but does not fully over heat just to the white line under the redline?

Check to make sure you still have a working thermostat in the cooling system I dont thing your coolant is staying in the radiator long enough to release heat. 60 mph might be pushing your luck with that rusted frame though.

What does it mean when you car overheats at high speeds and when stopped rpms go up and down while in neutral?
check egr valve
Cadillac 1996 deville overheats driving fast?
when overheating occurs at highway speeds the cause is usually. a radiator or coolant circulation problem, Check for a restricted or clogged radiator.
1993 e-150 van overheats when travelling at high speeds?
Check the fans on the radiator of the 1993 E-150 Van. The fans are supposed to turn on when the engine need cooled after reaching a certain temperature. This is usually due when the car is idling at lights or driving at higher speeds.
What could be the possible problems with a 1992 Ford Explorer that overheats while idling and driving under 35 mph but during freeway travel the temperature gauge cools down to normal?
Check and see if the fan cluch is good. Your fan. At higher speeds, the fan is not needed due to the high airflow. At low speeds and idle, you need the fan to operate to cool the car.
What causes a 1998 Mazda Millenia 2.5L to overheat and run rough while driving but at idle it overheats after a period of time but not when the blower fan is on high and the radiator fun is on?
The problem you seem to be having is the cooling temp sensor. It controls the fan speed which has two speeds. Try that.
How do you fix a 95 camaro from over heating?
Your question lacks info. But, if the engine overheats at idle, and the rad is in top shape, and the thermostat is good, and you have a mix of at least 50/50 water/antifreeze, and the fan pulls good air, clutch fan I assume, then add an electric fan to the out side of the rad, to suck more air. If the engine overheats at higher speeds, then have the rad. checked, ( note that the fins on the rad might close at higher speeds preventing air flow ), Rad might be in need of a new core, thermostat might need to be replaced, OR, not enough fan cowling around the rad, and the fan pulls air from around the rad, and not through it. Sure hope this helps to solve the problem.
What could cause a 1988 16v VW Golf GTI to overheat?
sounds to me like the thermostat has gone ... or possibly water pump failure (eg at 100K miles) or an oil problem. First check the coolant level. If it's at the proper level it is probably the thermostat It could be the thermostat, water pump, or even the radiator fan switch. If it only overheats when the car is driven at low speeds or in heavy traffic it might be the fan switch. If it overheats even when moving at a constant high rate of speed (over 45mph or so) then it is probably the water pump or thermostat.

Can you blow up a motor by the revolutions being up to high driving down the road?
Yes, every engine has a "red line." If there is an RPM guage, the redline is clearly marked by red numbers. If you redline it too much, you can tear it up. But under normal conditions, that shouldn't be occurring. About the only way to redline one is to be drag racing, or just revving it constatntly in nuetral, and most new cars have a "governor" built into the PCM that will not allow you to redline it. Yes, you can. Many cars do not have a built in rev limiter and/or are equipped with a transmission allowing the driver to select the gear ratio. This makes it possible to reach very high engine speeds. SSome things that can happen at excessive engine rotational speeds: -Oil film can break down at high pressure locations such as between cam and lifters/followers, main bearings, and rod bearings. This is equivalent to running the engine without oil. This is bad. -Valve float - Valve springs can fail to close the valves fast enough and in an interference (non-freewheeling) engine this can cause impact damage between piston and valve. -As engine speed increases, so do forces on connecting rods. Connecting rods can break, but it is more likely to break a rod bearing bolt. In either case, this can hammer internal engine parts causing additional damage in a fraction of a second. Shrapnel can exit at dangerously high speeds. Block and crank are usually scrap metal at this time. Fires can occur. -Torsional forces can shear the crankshaft. The crankshaft becomes unbalanced and can weld itself at the main bearings. Pistons closer to the front of the engine lose their load and can briefly accelerate to even higher speeds, possibly breaking rods. Pistons at the rear end lose time with the valves and can impact them. Dangerous shrapnel can be ejected from the engine. Fires can occur. It is usually best to operate the engine only at speeds specified by the manufacturer. The engineers who designed the engine have determined that this speed is safe.
