Depends on the car and what is actually wrong with it
Yes, if the coolant is still clean and has not been in the system for long. But if you are changing the coolant at the recommended mileage of your cars manual then it should not be reused.
It depends on what sort of dents you want to repair. If you were repairing dents in cars or something else worth quite alot of money it would be.
This depends on the rating of the thermostat. Any where from 165 to 185 degrees is good.
Valvoline MaxLife coolant.
The cooling system is a closed system. If there is smoke (probably steam) there must be a leak in the cooling system somewhere.
In short no. Your cars cooling system is a sealed unit therefore it should not use any coolant whatsoever no matter the ambient temperature.
Don't! Most cars have a reservoir for radiator coolant ... add liquid to the reservoir. Opening the radiator cap introduces air into the sealed system ... you don't want air bubbles in the cooling system.
you pay money to a person at a car repair shop and they will fix your car
There is no repair cheat in GTA III for the PC. The only way to repair cars in the game is to drive into a so called Pay'n'spray garage. This will cost some money and will in return repair your car and change the colours. You can not repair cop cars such as the tank, FBI car, SWAT car or the Police car. You can not repair the ambulance or the firetruck either.
50% Anti-freeze and 50% clean water is generally used for engine coolant. This mix protects the cooling system from freezing down to -34 degrees F.
We would probably call the "Do Not Remove" cap the radiator cap. In most cars that cap is on the radiator. First - NEVERremove the cap unless the engine is stone cold. Hot water and steam could blast out of the radiator and burn you! Normally you would add coolant to the overflow tank if you are just topping off coolant that is a little low. If you have overheated the engine or blown a hose and lost most of the coolant, you would have to remove the radiator cap and refill the system there. If this happens, check a repair manual for your car, because some cars have a procedure to purge trapped air from the system that MUST be followed, otherwise the engine could be damaged.
Water alone is not used as coolant for automobiles.
