VOLVO S40 ENGINE COOLING

I Have Had The Cylinder Head Done. Car Has Power, No Overheating, Nothing. Except For The Coolant Reservoir Soaked With Brown Oil....

Just Recently My Fan Stoped Working So I Checked The Fuse And It Was Bad Then When I Changed Every Time I Turn The A/c On It Blows Again...

My Radiator Is Leaking, And I Need To Replace It. I Was Just Wondering How Long That Might Take.
