Can a radiator cap go bad?
A faulty radiator cap can result in engine overheating, loss of coolant or major engine damage. So, Pressurized cooling systems help prevent overheating and coolant loss. Also, It raises the coolant boiling point about 3-degrees F for each additional psi above atmospheric pressure.
How do I test a radiator?
What will happen if you overfill radiator?
Most of the time, excess coolant is expelled from an overflow hose. You’ll likely see a puddle of coolant beneath your car if this has happened. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
