In Wilmette, we’ve finally survived another Chicago winter. But while we’re busy swapping out parkas for light jackets, your car is still recovering from months of sub-zero temperatures, road salt, and heavy idling.
At Hong Kong Auto Service, we consider April the “Spring Cleaning” month for your vehicle. Most folks think about car washes and vacuuming out the winter salt, but the most important cleaning happens under the hood.
The Big Three: Fluids You Can’t Ignore
Fluids are the lifeblood of your vehicle. Over time, they break down, become contaminated, or lose their ability to protect vital components. Here is what we’re looking at this month:
1. Cooling System Flush
Winter is tough on your radiator, but summer is even tougher. Antifreeze (coolant) doesn’t just prevent freezing; it also prevents boiling and corrosion.
- The Issue: Old coolant becomes acidic, eating away at your water pump and radiator from the inside out.
- The Spring Fix: A professional flush removes scale and rust, helping your engine stay cool on those 80-degree, humid days.
2. Brake Fluid Exchange
Brake fluid is hygroscopic, meaning it actually attracts and absorbs moisture from the air.
- The Issue: Moisture in your lines can lead to internal rust and, more importantly, a “spongy” brake pedal or reduced stopping power.
- The Spring Fix: We purge the old, moisture-heavy fluid and replace it with fresh, high-performance fluid to keep your stops crisp and safe.
3. Transmission Fluid
Your transmission works harder in the winter to shift through cold, viscous fluid.
- The Issue: High heat and heavy friction break down the additives in transmission fluid, leading to rough shifts or even transmission failure.
- The Spring Fix: A fluid exchange ensures your gears stay lubricated and cool, extending the life of one of your car’s most expensive components.
Why “Flushing” is Better Than Just “Topping Off”
You wouldn’t wash your dishes in dirty bathwater, right? Topping off fluids is a temporary fix, but it leaves the contaminants and “sludge” behind. A professional flush at our shop ensures that the old debris is actually removed from the system before we introduce fresh, clean fluid.
