Overheating Destroys Engines — Fast

Your cooling system keeps your engine alive. A small leak or a tired water pump can quickly turn into a warped head, a blown gasket, or a seized engine.

Blackstone services every part of your cooling system — radiators, water pumps, thermostats, hoses, and coolant. We pressure-test to find leaks, flush old coolant that's lost its protection, and replace worn parts before they leave you stranded with a steaming hood on the side of I-270.

Cooling System & Radiator Repair FAQs

Common Questions

What should I do if my car overheats?

Pull over safely, turn off the engine, and let it cool — never open a hot radiator cap. Driving an overheating engine can cause thousands in damage. Have it towed or call us for advice.

How often should coolant be flushed?

Most manufacturers recommend a coolant flush every 30,000–50,000 miles or 3–5 years. Old coolant becomes acidic and loses its ability to protect against heat and corrosion.

Why is my car leaking coolant?

Common sources are the radiator, hoses, water pump, or a failing gasket. We pressure-test the system to find the exact leak rather than guessing.

How long does a water pump last?

Typically 60,000–100,000 miles. Since failure causes overheating, many shops replace it during timing-belt service — we'll advise based on your vehicle.
