Keep Your Cool on the Road

Overheating is often caused by low coolant, a coolant leak, a failing thermostat, a clogged radiator, a bad water pump, a faulty radiator cap, or a failed cooling fan. In some cases, combustion gases entering the cooling system (such as a head gasket issue) can also cause overheating. Frogtown Automotive performs cooling system diagnostics to identify the real cause before repairs begin.

Signs include a sweet smell, puddles under the vehicle, frequent low coolant, steam from the hood, or a temperature gauge that climbs higher than normal. You may also notice crusty residue near hoses, the radiator, or the reservoir. A proper coolant leak test confirms where the leak is coming from.

A cooling system pressure test applies controlled pressure to help reveal leaks in hoses, clamps, the radiator, heater core, water pump, and seals. This test helps us find slow leaks that can cause overheating and prevent repeat breakdowns.

Topping off is a short-term fix, but old or contaminated coolant may require a coolant flush. Fresh coolant helps prevent corrosion, protects internal cooling passages, and improves overall cooling system performance. We’ll recommend the right service based on coolant condition and manufacturer guidelines.

A bad thermostat can cause overheating, temperature swings, poor cabin heat, or the engine running too cool. A thermostat stuck closed may cause rapid overheating; stuck open can reduce efficiency and heat output.

Common signs include overheating at idle, temperature creeping up in traffic, rusty or discolored coolant, weak heat, or visible leaks/corrosion. We can test cooling performance and inspect airflow and flow restriction issues.

Yes. The water pump circulates coolant through the engine and radiator. If it leaks, the bearing fails, or it stops moving coolant properly, your vehicle can overheat quickly. We inspect pump operation during cooling system diagnostics.

Overheating at idle often points to cooling fan problems, restricted airflow, low coolant, or radiator efficiency issues. Driving airflow can temporarily compensate, which is why the problem may show up most in stop-and-go traffic.

No. Driving while overheating can cause severe engine damage, including warped components and head gasket failure. If the gauge spikes, pull over safely, shut off the engine, and schedule an overheating diagnosis.

We handle coolant leak repair, radiator replacement, thermostat replacement, water pump service, hose and clamp repair, cooling fan diagnostics, and coolant flushes to restore reliable cooling.
