Explanation:
1. If there is a small leak in the system, when the coolant contracts, some air will be sucked into the system and less coolant from the overflow tank causing an air pocket to form at the top of the radiator. That's why the radiator of an automobile is not filled completely .
--------------------------------------------------------------------------------------------------------------
2.Car tyres are filled with lesser air in summer because during the hot summer days, when you drive, the temperature of tyres increases faster, consequently, the heated air inside the tyres expands and its pressure rises quickly, which can lead to tyre blowout with disastrous consequences.
