Radiator & Cooling System Repair FAQs

Can I keep driving an overheating car?

No. Pull over and shut the engine off — driving hot can warp the cylinder head within minutes.

Can a mobile mechanic replace a radiator?

Yes. Most radiator, hose and thermostat jobs are done in a driveway in 1–3 hours.

What coolant does my car need?

It depends on the manufacturer spec (OAT, HOAT or P-HOAT). We match the exact type.

Why does my car overheat only in traffic?

Usually a failing radiator fan, fan relay or low coolant — airflow drops when you're stopped.
