๐ฅถ FALL MAINTENANCE #5: YOUR COOLING SYSTEM
Boyertown winters can be tough on your vehicle. Don't forget about the system that keeps your engine at the right temperature.
When most people think about a cooling system, they think about overheating in the summer.
But your cooling system matters in cold weather too.
And a problem that starts with a low coolant level, an old hose or a small leak can eventually turn into a much bigger repair.
Here are some things Boyertown drivers should watch for:
๐ง CHECK YOUR COOLANT LEVEL
Low coolant can lead to overheating, poor cabin heat and other problems. If you keep adding coolant, don't just keep topping it off. Find out where it's going.
๐งช WHEN WAS YOUR LAST COOLANT FLUSH?
Antifreeze doesn't last forever. Coolant breaks down over time and the correct service interval depends on your vehicle and the type of coolant it uses.
If you can't remember the last time your coolant was changed, check your maintenance records and see what your vehicle manufacturer recommends.
๐ LOOK FOR LEAKS
Hoses, the radiator, water pump, thermostat housing, reservoir and connections can all develop leaks.
A small coolant leak can become a big problem when the coolant level gets too low.
๐ SMELL ANTIFREEZE INSIDE YOUR CAR?
A sweet coolant smell coming through the vents can be a warning sign of a leaking heater core.
You may also notice:
๐ช Windows fogging or icing up on the inside
๐ง Damp or wet carpet inside the vehicle
๐ฅ Weak or inconsistent heat
Don't automatically assume inside window fogging or icing is just winter weather. Excess moisture in the cabin can have several causes, and a leaking heater core is one of them.
๐ก๏ธ WATCH YOUR TEMPERATURE
If the temperature gauge starts climbing, an overheating warning appears, or you see steam or lose coolant, don't ignore it.
An overheated engine can cause serious damage. Excessive heat can damage a head gasket and, in severe cases, warp or crack engine components. A failed head gasket can also allow coolant into the engine oil and cause major internal engine damage.
That's a lot more expensive than finding a cooling-system problem early.
