The engine overheats and parts can melt, crack, even explode (massive expansion due to heat.)
coolant temperature sensor are located where the coolant runs in the block near the thermostat housing normally the connector are on top of the sensor and the sensor itself screws in with a deep socket. The temperature sensor is usaully located where the coolant runs OUT of the engine close to thermostat housing.
Coolant will enter the combustion chamber. This will cause serious engine damage. Your Catalitic converter & O2 Sensors will also be ruined. STOP driving this vehicle until you have this repaired.
coolants are specially treated liquids formulated to cool your engine instead of water(untreated) Coolant is a substance, usually a kind of liquid made under a certain chemical formulae stored in a device called radiator on a motor vehicle (or other kind of machinery), and it runs/ circles in the cooling system of the vehicle to reduce the heat or the temperature of the engine rises by the running or operating of the vehicle’s engine whenever the vehicle’s engine operates; thus the overheat can be prevented and the engine can be ensured to performing in a mechanical condition.
Assuming you still have some form of coolant (water) in your radiator then the coolant will freeze when the weather is cold enough, coolant expands when it freezes, this may cause permanent damage to your engine, such as split pipe's, burst radiator, cracked engine block
If it is an internal leak the coolant will end up in the crank case mixed with your oil and it will ruin the bearing/engine - if external leak then the engine will overheat when it runs low on coolant, and blow your head gasket
Engine knock happens when an unbalanced air and fuel combination occurs inside of an engine cylinder. If the problem is not corrected the vehicle runs the risk of having a piston malfunction.
You probably have an oil leak somewhere that needs to be repaired. If the engine runs completley our of oil it will freeze up and become unrepairable. Oil is very important to a running vehicle.
If your vehicle runs out of water/anti-freeze the engine will overheat and seize. You should receive ample warning before this happens but the consequences for ignoring the warnings can be disasterous. You could be looking at replacing your entire engine.
our car runs faster depending on the engine
I would say yes, if oil has mixed with the coolant, that's the most probable cause.
No. Coolant only runs through your radiator into the engine and back again. Your condencer is part of your A/C system.
Low engine coolant--when you step on the gas water pump runs faster and is calling for more coolant--check level
