to increase the waters boiling point
to check for leaks or in the case of the cooling system preasure cap to raise the boiling point of the coolant
The cooling system
Back flushing on a cooling system is when you get all of the trapped air out of your cars cooling system. This will make your vehicle run better after you do it.
If the cap is not holding pressure or if it is damaged, the engine will overheat. The automotive cooling system must be pressurised, WHY?? its because when you pressurise the fluid, the boiling point will increase.

A plastic radiator will crack under extreme over heat conditions for example a defective thermostat or bad cylinder head gasket will cause a cooling system to over pressurise and rupture.
To avoid over heatig
There are cooling systems for the engine and the transmission. These are separate, and necessary to keep the vehicle from overheating.
No, but they can cause it to overheat
No, you cannot put Pepsi inside of your car's cooling system. This could seriously damage if not make your vehicle inoperable.
