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.
because when you stop the motor is hot from driving but when you drive it is cool because you are moving.
Defective blower motor?
No not at all if you are driving this car stop at once and fix it or you will blow the motor eventually
clean the heat filters
Either the motor has a short, or is seized, for some reason.
Shorting the motor's electrical supply will blow the fuse and the motor will run down and stop.
No. Driving the car with a blown head gasket will cause the motor to fail completely. Get the car towed to a mechanic as soon as possible.
defective motor will not run, also cause the blower motor speed resistor to burn out and eventually blow the fuse. a motor with defective bearings will draw excessive current causing either the fuse to blow or cause the motor to overheat
If it is not supposed to blow air in that direction, the motor is going backwards. The run capacitor has probably failed. Unless the motor was recently replaced then it is either the wrong motor or it is miswired.
The blower motor resistor is generally located close to the blower motor.
Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Not Having any oil in the motor
Your front blower motor has gone out. There is a front and a rear blower motor.
I hear he's driving a bus these days
v 12 motor swap
that's a hard question but i would say 30
Defective blower motor, blown fuse, or a defective Blower Motor Resistor Pack.
the blower motor not getting power blown fuse or thermal switch or motor just went out
sounds like power feed to blower motor is non existant, and or blower motor is finished. The cycling of the compressor only means cold is being made, but not being blown into the car interior.
fuse, wiring, blower motor, blower motor switch, blower motor resistor
Blower motor not working? Bad fuse, relay or motor See if you are getting power to motor
The blower motor is tired. It will eventually blow a fuse and/or burn out the blower motor speed resistor. Time to replace the blower motor. Also check connections for high resistance damage (melted connections).
the easiedt way to fixyour blower motor is to reverse poliality on the blower moter just reverse the wires.who ever worked on this installled the blower motor wheel so that it turned wrong, either reverse poliarity or take blower motor out and put wheel on right .good luck
