What happens if you put too much coolant in the radiator?

When you overfill the coolant reservoir, there won’t be much space left for the heated coolant to expand. As a result of which, the pressure inside the reservoir would increase gradually. When this happens, the cap of the tank will open, and the hot coolant would pop out like a puddle of lava.

How much coolant Do I need to fill an empty radiator?

You should have between 1 1/2 and 2 gallons in the fluid bucket or catch basin. Be sure the radiator cap has been removed which will help you get most of the coolant out if the system.

Why is my coolant running out so fast?

Antifreeze leaks can be caused by a variety of things but the two most common factors are age and dirty coolant.

Flushing your cooling system is the best way to stop this type of leak.

Does a cooler engine run better?

Performance vehicles move parts even quicker, from engine internals, to transmission gears, to differentials, only making components hotter. Cooling temperatures throughout the drivetrain will not only keep a car running longer, but will potentially help it run quicker.
