💬 Frequently Asked Questions

How do I know my radiator is bad?

Visible coolant leaks, low coolant with no obvious leak, overheating, or bent/damaged fins from road debris. P0128 (engine not reaching operating temp) and P0217 (engine overtemp) can also point here.

Can I drive with a leaking radiator?

Briefly, with frequent coolant top-offs - but driving overheated will warp heads or destroy the engine. Not a wait-and-see repair.

How long do radiators last?

Typically 80,000-150,000 miles. Skipping coolant changes shortens life - acidic old coolant eats the radiator from inside.

Should I get aluminum or plastic-tank radiator?

Stock-style plastic-tank is fine for most cars. All-aluminum is for performance/heavy-duty use - more expensive but more durable.

Will a coolant flush fix a leaky radiator?

No - a flush cannot fix a physical leak. But flushing during replacement is good practice for the new radiator.
