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.

ARE MY BRAKES SAFE?

By Stacey Diaz • October 14, 2025

October is more than just pumpkin patches and crisp fall air. For many families in Monterey, it's also the start of darker evenings, wetter roads, and more time on the road. That’s why October is the perfect time to think about one of the most important safety features on your vehicle: your brakes. At Wayside Garage, we participate in the Brakes for Breasts campaign every October. It's not just about brake repair — it’s about raising awareness, supporting breast cancer research, and keeping our community safe on the roads. ________________________________________ What Are the Signs Your Brakes Might Need Attention? Your brakes are your first line of defense in an emergency. If you’re noticing any of these symptoms, it’s time to get your brakes checked: • Squealing or grinding noises • A soft or “spongy” brake pedal • Car pulling to one side when braking • Vibration or shaking when you press the brakes • Increased stopping distance Ignoring these signs can lead to expensive repairs down the road — or worse, a serious accident. We always say: if it feels off, bring it in. ________________________________________ Why Brake Inspections Matter More in Fall With more rain, shorter days, and holiday travel ahead, your brakes are under more stress in the fall. At Wayside Garage, we see an uptick in emergency brake repairs this time of year — many of which could have been avoided with a quick inspection. Our certified technicians will perform a comprehensive brake check, looking at: • Brake pads and rotors • Brake fluid level and condition • Brake lines and hoses • Calipers and hardware And if you’re part of our Wayside Garage Maintenance Plan, your brake inspections are included with your scheduled services.
