A coolant drain and fill is vital to your car. It keeps your fuel system’s seals and gaskets supple so they won’t leak, and anti-corrosives in the fluid protect the metal in your engine from corrosion.

After about two years or 30,000 miles, the coolant begins to break down and can no longer protect your engine the way it’s meant to. You then need a coolant drain and fill repair. 

Should I Get a Coolant Drain and Fill?

Coolant deteriorates eventually and needs to be tested, but it can be hard to tell by the way it looks. Testing may show that the cooling and antifreeze still provide adequate protection. However, antifreeze gets acidic over time, which makes it unable to combat corrosion. Smart vehicle owners can often diagnose a coolant problem, but the best idea is to contact DiscountMechanic to book a service or diagnostic appointment.

What if My Car’s Coolant Drain and Fill System Is Corroded?

If you’ve ever lifted your hood and discovered a powdery white or blue substance around your battery’s terminals, that’s not pollen from trees; you’re actually looking at dried battery acid! This residue will corrode your coolant drain and fills and the terminals themselves if it isn’t cleaned away as part of regular maintenance on your battery. Aim for every other oil change for the best results. If the corrosion has already gotten to your cables, however, they’ll definitely need to be replaced. There’s no way to “turn back the clock” when that acidic residue has already eaten away at your wire casings.

What Are the Signs of a Sick Coolant System?

If your car overheats, emits a sweet smell (from antifreeze), or leaks and continuously requires a top off, you may have a coolant issue. It isn’t difficult to learn the symptoms of a sick cooling system. However, ignoring them can cause serious issues if you’re planning extended trips in the summer time.
