Car Overheating

An overheating engine is a time bomb. The longer you drive it hot, the more damage you're doing — and the more expensive the repair becomes.

Car overheating means the cooling system isn't removing heat from the engine fast enough. Common causes include low coolant from a leak, a failed thermostat stuck in the closed position, a dead cooling fan (electric fans fail more often than you'd think), a clogged radiator, a broken water pump, or a blown head gasket that's pressurizing the cooling system with combustion gases. In Jacksonville's brutal summer heat, even a marginal cooling system can push past its limits in stop-and-go traffic.

When the temperature gauge hits the red zone or a warning light comes on, pull over and shut the engine off immediately. Continuing to drive risks warping the cylinder head, blowing the head gasket, cracking the block, or seizing the engine — each of those is exponentially more expensive than whatever caused the overheating in the first place. Let the engine cool for 30+ minutes before checking the coolant level. Never open a hot radiator cap — the system is pressurized and will spray boiling coolant.

Frequently Asked Questions

What should I do if my car overheats?

Pull over, shut the engine off, and wait for it to cool. Don't open the radiator cap hot. Call a mechanic — don't try to drive to a shop.

Can I add water if my coolant is low?

In an emergency, plain water works temporarily to get coolant level up. Use a proper coolant mix as soon as possible, and find the leak.

Still not sure? Call a real mechanic.
