After a long highway run if let the car sit for a while there's coolant loss , Seems like it somehow overflowed or leaked from coolant reservoir cuz i can find a wet patch near left tire.

Later i found that one of my radiators fan was not working , Now i fixed it and So far there's not been any coolant loss

Initially i was suspecting coolant reservoir or one of the hose has developed a leak, But now that it doesn't leak anymore leaves me confused...

Is this normal to overflow or leak from the coolant reservoir on overheating?

Wondering if i should change the reservoir??

Please give your thoughts

coolant gets to hot, builds up pressure, releases coolant thru the pressure vent built into the reservior cap.
