Why a Radiator Drain & Fill Is More Important Than You Think

Why a Radiator Drain & Fill Is More Important Than You Think

Cooling System Service at Weldon Spring Auto & Tire

Your vehicle’s cooling system works hard to keep your engine at the right temperature—and it needs clean, healthy coolant to do the job. At Weldon Spring Auto & Tire, we recommend routine radiator drain & fill services to protect your engine from overheating and long-term damage.

Coolant (also known as antifreeze) isn’t just there to regulate temperature—it’s specially formulated with additives that prevent corrosion and buildup inside your radiator, water pump, and other cooling system components. But over time, these additives break down, leaving your system vulnerable. If the coolant becomes too acidic, it can actually start to corrode the very parts it’s supposed to protect.

A simple pH test can tell us whether your coolant is still doing its job or if it’s time for a change. Not sure when it was last done? No problem—you can have it checked the next time you’re in for an oil change.

Keeping up with cooling system maintenance is one of the easiest ways to avoid overheating, leaks, or costly repairs down the road. Give Weldon Spring Auto & Tire a call today, and we’ll schedule a convenient time to check your coolant and help your engine stay cool under pressure.
