Why Is My Car Overheating?

Potomac, MDTony Automotive

If your temperature gauge climbs into the red, pull over safely, shut the engine off, and let it cool before you do anything else — then call Tony Automotive at 301-401-6669. Driving an overheating engine even a short distance can warp the head, blow a gasket, or ruin the engine entirely, and those repairs cost far more than the fix you started with.

Overheating almost always traces back to the cooling system. The usual culprits are low coolant from a leak, a failing water pump, a stuck thermostat, or a clogged or damaged radiator. Any one of them stops your engine from shedding heat, and Potomac summer traffic on River Road makes it worse when you are crawling along with little airflow.

The trap drivers fall into is topping off the coolant and hoping the problem goes away. If coolant is low, it went somewhere, and that means a leak that needs to be found and fixed. Our cooling system service pinpoints the real source instead of masking the symptom, so you are not stranded again next week.

At Tony Automotive we test the whole system — radiator, water pump, thermostat, hoses, and coolant condition — and give you an honest diagnosis. If you are driving anywhere near Potomac and your car runs hot, do not push it. Call 301-401-6669 and we will keep a small problem from becoming a new engine.

[ 01 ]Common questions

Asked before,
answered straight.

What should I do if my car overheats?

Pull over safely, turn the engine off, and let it cool. Do not keep driving. Then call 301-401-6669 so we can diagnose the cause before it damages the engine.

Is it safe to just add coolant?

Only as a temporary measure. If coolant is low there is usually a leak, and topping off without finding it means you will overheat again.
