V6/V8 and turbocharged engines often need bigger or dual radiators.
Electric fans share mounting and are often replaced at the same time.
Best practice to replace - $30-$80 added.

Briefly, with frequent coolant top-offs - but driving overheated will warp heads or destroy the engine. Not a wait-and-see repair.
Typically 80,000-150,000 miles. Skipping coolant changes shortens life - acidic old coolant eats the radiator from inside.
Stock-style plastic-tank is fine for most cars. All-aluminum is for performance/heavy-duty use - more expensive but more durable.
No - a flush cannot fix a physical leak. But flushing during replacement is good practice for the new radiator.
