my car over heated last week from a blown coolant hose. when i noticed my guage hit the red zone i found a place to pull over. meanwhile when i accelerated it made a tapping sound when ever i touched the gas. once pulled over i ran water through radiator to find leak. i fixed my hose (leak) and filled with anti freeze. i got home runnig fine. car runs really hot 2 days later... i see im low on fluid in radiator(water boiled when it got to hot) i filled with antifreeze and runs good. week later and current day when i accelerate with load on engine it makes a poping sound and a loud clicking/ tapping
