BANNSIDERS skipper David Ogilby opened the scoring as early as the 12th minute when he got on the end of a precision free-kick from Stephen Lowry to beat Chris Keenan.
Then, four minutes later, Johnny Black made it 2-0 with a 25-yard half-volley.
Curtis Allen thought he had added a third on 54 minutes only for his neat finish to be ruled out offside.
But, on 77 minutes, Coleraine did grab their third when a Black free-kick ended up in the visitors net via the unintentional help of defender David McAlinden.
It was almost four a few minutes later after referee Stephen Weatherall awarded a penalty for a foul on Allen but the former Linfield man was unable to keep his subsequent spot-kick from going over the bar.
However, Coleraine did get their fourth with five minutes remaining through Lowry whose powerful drive from the edge of the area gave Keenan no chance.
