How Can You Tell If You Have A Bad Radiator?

Although our days are still warm, it’s time to get your vehicle ready for winter.  An important part that drivers often overlook in winter is the radiator.  When it’s icy outside, the coolant in the radiator expands and contracts, adding stress to the radiator.  If cracks and leakages in the radiator go unnoticed, the end result could be damage to the transmission.  

As strange as it sounds, an engine can overheat even during cold temperatures.  Don’t delay for this to happen before thinking about scheduling a radiator repair.  Damage to the radiator can cause an undulate effect throughout the vehicle and cause the vehicle to stop running altogether.  What could have been a minor repair to the radiator can turn into a major transmission job!

So how can you tell if you have a bad radiator? 

• Engine Overheats – The flow of coolant could be limited due to air inside the cooling system, clogged hoses, or too low of coolant level. 
• Leaking Radiator – The constant icy and expanding of fluid could cause cracks in the radiator unit.
• Hose Leak – A hose from the radiator to the engine allows the coolant to flow and cool off the engine.  Over time, these hoses wear our so have them checked frequently. 
• Thermostat Failure – The thermostat regulates the amount of coolant that is recirculated and ensures that the coolant in the engine stays within a particular temperature range regardless of the outside temperature. A failing thermostat prevents the flowing coolant to the engine.
• A Smoking Muffler – Actual smoke coming from the muffler could mean that the head gasket has been broken from an overheating engine.

Before winter come to full force make sure the antifreeze/water mixture in your radiator is still effective.  Your Auto mechanic may recommend flushing the cooling system, or easily topping it off.
