Then, what happens if radiator cap is loose?

A loose radiator cap will cause the system not to pressurize, resulting in overheating. Finally, the resulting overheating may strand the driver since the cooling system will have to cool down before it can be refilled and driven. If the engine is operated while overheated, severe mechanical damage may occur.

Additionally, how do you know when your radiator cap is bad? There are several warning signs that your radiator cap is not working right:

  1. You have a coolant leak: If your coolant is leaking, it could mean your radiator cap is bad.
  2. Your engine is overheating: If your temperature gauge starts reading high, your radiator cap could be at fault.

Likewise, how tight should coolant cap?

Do not do it when the engine is hot. So it looks to be just a simple snap cap , if that is the case. Then it is just a press fit until it snaps over the rim. Coolant should be half between cold and hot mark at rest.
