Vehicle radiators flush coolant through the engine to move heat away from the components and maintain a low temperature. You must get radiator repair immediately if an issue occurs to prevent malfunctions and significant repair costs. Below are four indications you should have a mechanic check your radiator.

Get Radiator Repairs if You Experience These 4 Issues

1. Engine Overheating

If you’re driving and the vehicle suddenly overheats, you’ll likely see steam coming out of the engine compartment from under the hood. Be careful not to touch the hood or engine components, as they’re much hotter than usual. Go to a mechanic for radiator repair to ensure there isn’t an issue with the coolant, water jacket deposits, or broken belts. 

2. Leaking Coolant

Vehicle radiators use coolant, also known as antifreeze, to keep the engine temperature even. These products—made from propylene glycol or ethylene glycol—absorb heat from the engine compartment and move it to metal fins that disperse the heat outside. If there isn’t enough coolant in the car, heat will build up in the engine.

If you notice greenish or bluish fluid under the vehicle, there is likely a coolant leak. The dashboard indicator lights may also signify that the coolant levels are low. Always having to add this fluid is also a sign that there is a leak.

3. Discolored Radiator

Most vehicle radiators will work for up to 10 years when properly maintained through regular inspections and coolant flushes. If you notice the radiator is discolored or rusty, visit a mechanic to replace the part before corrosion further damages the engine. Discoloration and rust can cause coolant leaks and overheat the engine, potentially leaving you stranded on the roadside.

4. Hot Dashboard Lights

The dashboard indicator lights in the vehicle may note that the engine or oil is too hot. This light could indicate a thermostat issue but may also require radiator repair as the engine is overheating. A mechanic will use a diagnostic device to read the code and establish the cause of the light, getting you back on the road safely.
