The Importance of Your Cooling System

Your engine generates an incredible amount of heat. The cooling system's job is to move that heat away to the radiator, where it's dissipated into the air. If any part of this system fails—whether it's a leaking hose, a stuck thermostat, or a clogged radiator—your engine will quickly overheat. Regular coolant flushes are also vital for preventing internal corrosion and keeping the system efficient.

Frequently Asked Questions

Why is my car overheating?

Common causes include a low coolant level, a leaking radiator hose, a failed water pump, or a stuck thermostat. A pressure test is the best way to find the leak.

How often should I flush my coolant?

Most vehicles require a coolant flush every 30,000 to 50,000 miles. Check your owner's manual for the specific interval for your car.

What is the sweet smell coming from my engine?

A sweet, maple-syrup-like smell is a classic sign of an antifreeze (coolant) leak. You should have it inspected immediately before it leads to overheating.
