Did Your Coolant System Survive the Winter?

May 14, 2014

With all of the harsh weather, cold temperatures and massive snow, many drivers are left wondering what will need to be repaired on their car to recover.  CarBetween sand, rock salt and other ice melt materials caking in the tire wells and getting thrown into the engine and all over the exterior of the car, no one is probably thinking about the cooling system of their car but they should.

Many people only think of their car’s cooling system as preventing over-heating when  they are blasting the air-conditioner when stuck in traffic (a no-no, of course) but during the winter they assume that Mother Nature will take care of the rest.  The reality is that your car’s coolant doubles as antifreeze and must remain stable at high operating temperatures.  If it does not the risk of the antifreeze freezing (yes, it is possible) when your car is unused and the temperature plummets is a very real and costly possibility.

It is a fact that winter can place stress on your car’s cooling system, so performing a few regular checks will only cost you a little time and possible save you a lot of money later.  Checking that the antifreeze/coolant is filled to the suggested level and performing a visual check of where your car is parked to ensure the automotive cooling system isn’t leaking are two simple steps anyone can do in a few minutes.  Additionally, checking for leaks on the radiator can be done to a point.  More intensive steps such as checking the heater core, hoses, gaskets and freeze plugs can be done simply by your trusted mechanic.

Another potential hot spot is the water pump, essential for moving the coolant through the engine to help dissipate the heat generated during operation.  If it is leaking or defective then the coolant/antifreeze will not be moved through the engine.  In conjunction with the water pump, the thermostat should be checked as its job is to open when the engine temperature rises so the coolant/antifreeze can flow.  If the thermostat is stuck open the engine will have trouble reaching its optimal operating temperature.  A quick way to diagnose this problem is when you turn the heat on inside your car.  If the air coming out of the vent only gets lukewarm then it is likely the thermostat is defective or worn out and should be replaced immediately.

If any of the components of your vehicles cooling system fail it can cause problems with others parts of your engine.  And once we put this brutal winter behind us the last thing any of us need to deal with are the unnecessary costs and inconvenience involved in having our car in the shop.
