Why Is My Car Leaking? Radiator Hose

September 18, 2024

Why Is Your Car Leaking | Radiator Hose

Hey there, Stacey here from Wayside Garage in Seaside, California! Today, we’re tackling a common car issue that could sneak up on you—a fluid leak. Specifically, we're diving into cooling system leaks, which can lead to bigger problems if not addressed.


What We Found on This 2014 Hybrid C-Max

One of our recent customers brought in a 2014 Hybrid C-Max with a mysterious fluid leak. After a thorough inspection, we found two leaks, but today we'll focus on the cooling system. We discovered that the radiator hoses, particularly the lower hose, were leaking.


The Importance of Your Radiator Hoses

Radiator hoses aren’t just small pieces of rubber. In this case, the lower radiator hose assembly was the culprit, and you can’t simply replace a section—it’s an all-in-one deal. Given the vehicle's age and mileage, we also replaced the upper radiator hose as part of preventative care.


Radiator hoses are essential to your engine’s health because they help regulate temperature. Over time, these hoses can crack or burst, leading to engine overheating or even severe damage like a blown head gasket.


When Should You Replace Your Radiator Hoses?

We recommend replacing your radiator hoses every 60,000 miles or every five years—whichever comes first. Even if your hoses look fine from the outside, wear starts from the inside. Waiting too long can lead to leaks like the one we found.


Preventative Maintenance is Key

At Wayside Garage, we're all about preventative maintenance. Regular checks and services can help prevent breakdowns and expensive repairs. For instance, we suggest a cooling system service every two to three years or 30,000 miles to ensure your coolant pH and freeze protection are up to par.


Why Regular Inspections Matter

Many leaks go unnoticed until they’ve caused damage. That’s why we offer a complimentary inspection every 6 months as part of our maintenance plan. This proactive approach can keep your car running smoothly well past 200,000 miles.


If you're due for a cooling system check or suspect a leak, give us a call at (831)-899-2425 or schedule an appointment online at www.waysidegarage.com. Let’s keep your car in top shape!

How Do I Know If My Tires Are Safe to Drive On? Tips from Wayside Garage in Seaside, CA for National Tire Safety Week Tire safety is one of those things drivers don’t think about — until it’s too late. But as a local shop owner with over 38 years under the hood, I can tell you: the health of your tires has a major impact on how your car handles, brakes, and keeps you safe out on the road. That’s why we’re proud to support National Tire Safety Week 2025 , happening June 30 to July 4 — an annual effort from the U.S. Tire Manufacturers Association to educate drivers on proper tire maintenance. And right here at Wayside Garage in Seaside, CA , we’re doing our part to help folks check in before they check out for summer road trips. πŸš— So, How Do You Know If Your Tires Are Safe? It really comes down to four key checks — easy to remember with the acronym P.A.R.T .: πŸ”Ή P = Pressure Low tire pressure leads to poor fuel economy, sluggish handling, and faster wear. We recommend checking pressure monthly, especially before long drives. Always check when your tires are “cold” — that means before you hit the road, not after a grocery run. πŸ”Ή A = Alignment If your car’s drifting left or right, or your steering feels off, your alignment may be out of whack. Misalignment causes uneven wear, hurts handling, and can shorten your tire life — not to mention your patience. πŸ”Ή R = Rotation You’d be surprised how fast tires can wear unevenly. We rotate tires every 5,000–7,500 miles to make sure all four tires wear evenly. This extends tire life and keeps your vehicle handling the way it should. πŸ”Ή T = Tread Tires need grip, especially in wet or winding road conditions. We recommend checking tread depth monthly. If your tire tread is worn down to 2/32 of an inch or less — or if you see visible cracking or bulges — it’s time to replace them. πŸ’‘ Quick Tip: Stick a penny into your tread, Lincoln's head down. If you can see all of Honest Abe's noggin, your tread is too low. πŸ› οΈ What We Offer at Wayside Garage, Seaside CA We’ve been serving the Seaside community for nearly four decades, and tire safety is something we don’t take lightly. Our tire services include: Tire pressure checks and adjustments Computerized wheel alignments Tire rotations and balancing Tread inspections and honest tire replacement recommendations Tire age checks — rubber breaks down over time, even if your tread looks good. Most tires should be replaced every 6 years, regardless of wear. Whether you're planning a road trip or just commuting to work, swing by Wayside Garage in Seaside for a tire check. No pressure (pun intended) — just experienced, straightforward service you can trust. ❓ FAQ: Tire Safety Questions We Hear All the Time Q: How do I know when my tires need to be replaced? A: If your tread is worn past 2/32", your tires are over six years old, or you notice bulges or cracks — it’s time to replace them. Q: How often should I rotate my tires? A: Every 5,000 to 7,500 miles. We include this as part of routine maintenance at Wayside Garage. Q: Can alignment affect tire wear that quickly? A: Absolutely. One pothole or curb can knock alignment off. If your car pulls or your tires wear unevenly, it’s time for an alignment check. Q: What tire pressure should I use? A: Check your driver’s door sticker or owner’s manual — never use the number printed on the tire itself. 🏁 Drive Into Summer with Confidence This National Tire Safety Week , don’t just guess your tires are safe — know they are.
