Why is my truck leaking?

Why is my truck leaking?

Hi, it's Stacey at Wayside Garage. Today, we're diving into an issue we found on a 2019 Ford Expedition with a 3.5-liter engine. The vehicle was brought in for an oil leak concern, but upon inspection, we discovered the real culprit was a leaking water pump.


Identifying the Leak

When our client noticed what they thought was an oil leak, it turned out to be coolant leaking from the water pump. Alan, our certified technician, found that the water pump bearing had failed, leading to the coolant leak. It's a common misconception to confuse coolant leaks with oil leaks, especially if the coolant hasn't been changed regularly. Over time, coolant can degrade, becoming acidic and changing color, which can easily be mistaken for oil.


The Importance of Regular Coolant Maintenance

Regular maintenance of your vehicle's cooling system is crucial. Coolant should be changed at intervals recommended by your vehicle manufacturer. If not maintained, the coolant can break down and become acidic, affecting the pH level and causing electrolysis. This can lead to corrosion and excessive wear on the water pump bearing, ultimately causing it to fail.


What Happens When a Water Pump Fails?

In the case of the Ford Expedition, the water pump's bearing went out. When this happens, the coolant can leak through a small "weep hole" on the pump, which is designed to indicate a failing water pump. The leaking coolant then drips onto the engine block and onto the ground, signaling a problem.


Signs Your Water Pump Might Be Failing

1. Coolant Leak: A noticeable coolant leak under the vehicle is a clear sign.
2. Overheating: If your engine is overheating, it could indicate a problem with the water pump.
3. Whining Noise: A high-pitched whining noise from the front of the engine could mean the water pump bearing is worn out.
4. Corrosion or Build-Up: Visible rust or build-up on the water pump.


Preventative Measures

To avoid such issues, it’s essential to follow a regular maintenance schedule. At Wayside Garage, we recommend having your vehicle inspected every six months or every 5,000 miles. Our complimentary inspections, as part of our maintenance plan, help identify potential problems before they become major repairs.

These days, keeping your car longer just makes sense. New vehicle prices, rising interest rates, higher registration fees, and insurance costs have more folks than ever asking: 👉 “ How do I make my car last longer?” At Wayside Garage, we specialize in helping our clients get the most life out of their vehicles with affordable, preventative maintenance — and we’ve been doing it for generations. Why Car Maintenance Is Smarter Than Buying New The cost to maintain your current car is dramatically lower than replacing it. Here’s a quick comparison: Maintaining your vehicle: About $0.25–$0.30 per mile Buying new or newer: Anywhere from $0.80 to $1.20 per mile That’s a huge difference. We even have a cost-to-own video that breaks this down in more detail — just ask and we’ll send it to you! Tips to Make Your Car Last Longer Want to protect your vehicle (and your wallet)? Here’s how: 🔧 Stick to a Maintenance Schedule We recommend servicing your vehicle at least twice a year — ideally every four months. At Wayside Garage, we make it easy by pre-scheduling priority reservations for our customers. Here’s what to keep up with: Oil & filter changes Fluid checks & top-offs Battery & charging system tests (especially before colder weather) Brake inspections at least once a year Belts, hoses & filter checks annually 🚨 Don’t Ignore Warning Signs If you hear a strange noise or see a warning light, don’t wait. Catching small issues early can save you thousands and avoid roadside breakdowns. 🛞 Rotate & Align Tires A yearly wheel alignment protects your suspension, brakes, and tires — and improves fuel economy too. Real Customer Example: 300,000+ Miles Strong One of our long-time customers drives a Volkswagen we’ve maintained since it was nearly new. He just passed 300,000 miles — and it’s still going strong. Recently, we caught his wheel bearings needing replacement before they failed. The repair cost him around $800–$1,000 — less than one month’s payment on a new car. That fix will last him years, and he avoided a breakdown entirely. Be Proactive, Not Reactive That’s our best advice in one word: Proactive. Plan ahead. Know what’s coming. Spread out services to avoid big surprises. And treat your car like your body — the more care you give it, the longer it’ll serve you well. Need Help Keeping Your Car Running? At Wayside Garage in Seaside, CA , we’ve got your back.
