The Risks of Ignoring Your Car’s Fluid Leaks

October 31, 2024

Fluid leaks in your car may seem like a minor inconvenience—something you’ll get to eventually. But ignoring leaks could cost you more than just a stain on your driveway whether it's engine oil, coolant, transmission fluid, or brake fluid, every drop counts. These fluids are crucial for your vehicle’s performance and longevity , and letting a leak go unchecked can lead to serious damage, costly repairs, or even dangerous driving conditions.

1. Damage to the Engine from Oil Leaks

Your engine relies on oil to keep all its parts well-lubricated and functioning properly. If your car is leaking oil, it can lead to decreased lubrication, causing friction between engine components. Over time, this friction can result in severe engine damage, including worn-out pistons, overheated parts, and, eventually, engine failure.

Even if the leak seems minor at first, losing oil steadily means your engine is being deprived of the very thing it needs to stay cool and efficient. If left unchecked, an oil leak can lead to a full engine breakdown—one of the most expensive repairs a car owner can face. Regularly checking oil levels and addressing any leaks quickly can save you from an engine rebuild or replacement.

2. Overheating Due to Coolant Leaks

Coolant, or antifreeze, is responsible for regulating your engine’s temperature. When coolant leaks, your engine becomes prone to overheating. This can cause the engine block or cylinder heads to crack, leading to massive repair bills. Even worse, if you continue driving with low coolant levels, you could experience a full engine meltdown, leaving you stranded.

If you notice a puddle under your car that’s green, orange, or pink, you might be looking at a coolant leak. Failing to act quickly on this can lead to a domino effect of engine problems, from warping metal parts to a complete failure of the cooling system. Ensure that any coolant leaks are repaired immediately to avoid an overheated engine.

3. Brake Fluid Leaks

Out of all the fluid leaks you could encounter, brake fluid leaks are by far the most dangerous. Brake fluid is essential for your car’s ability to stop effectively. When this fluid leaks, it reduces the pressure in your braking system, making your brakes less responsive. This is an inconvenience and a significant safety hazard , as it can lead to brake failure.

If you notice any brake fluid leaking (it’s typically clear or light brown and slippery to the touch), don’t wait. Even a small loss of brake fluid can severely compromise your ability to stop, putting you and others on the road at risk. A professional should address Brake fluid leaks immediately to ensure your vehicle remains safe to drive.

4. Transmission Fluid Leaks Can Lead to Costly Repairs

Transmission fluid lubricates the gears and moving parts inside your transmission. A leak in this system can lead to gear slipping, slow shifting, or complete transmission failure. If you spot red or brown fluid under your car, it’s likely transmission fluid.

Ignoring a transmission fluid leak can quickly turn into a costly repair. Replacing a transmission can be one of the most expensive fixes, with costs often running into the thousands of dollars. By catching the problem early and addressing it, you can prevent catastrophic transmission failure and extend the life of your vehicle’s transmission.

5. Power Steering Fluid Leaks and Steering Control

Your power steering system relies on fluid to provide the hydraulic pressure necessary for smooth steering. When power steering fluid leaks, you’ll notice that your steering becomes stiff or difficult, making it hard to control your vehicle. If the leak is severe, it could cause a complete loss of power steering, which can be dangerous, especially in tight situations or at high speeds.

Typically, power steering fluid is reddish or light brown, so if you see a puddle of this color under your car, it’s best to get it checked immediately. Ignoring a power steering fluid leak not only puts extra strain on your steering system but can also increase the risk of an accident if you lose steering control while driving.

When it comes to wheel safety, lug nuts don’t always get the attention they deserve. These critical fasteners are what keep your wheels securely attached to your car, and they need to be tightened to a very specific level of force—known as torque. Get it wrong, and you're risking more than just a loose wheel.

It’s difficult to drive anywhere in the Bay Area and not see a lot of Subaru vehicles. Whether it’s the Subaru Crosstrek, WRX, Outback, Forester, or Ascend, Subaru vehicles are everywhere. At Toole’s Garage we are big Subaru fans. Subaru vehicles are built for the great outdoors, and of course California provides plenty of opportunity for on-road and off-road adventures. All wheel drive (AWD) comes standard on many Subaru models, and can provide consistent traction whether you are on a muddy road, or skiing in the Sierras. If a roof rack did not come standard with your model, it’s easy to add. And of course, interior space is pretty generous, especially if you drive an Outback or Ascent – you can stow plenty of camping and hiking gear. At Toole’s Garage we can provide your Subaru with the maintenance it needs to provide you with a reliable ride – wherever your adventures take you. We highly recommend regular oil change – it not only improves performance and extends engine life, but it also allows us to inspect various sub-systems of your Subaru to catch any impending problems (for example, older Subaru models were prone to oil leaks). And if a long summer trip is in the cards, we definitely suggest bringing it in for a checkup. Being a full service auto repair shop, Toole’s Garage can provide your Subaru with routine maintenance services, diagnostics, as well as major repairs. If your Subaru needs new brake pads, has the check engine light “on”, suffers from transmission problems, or needs major engine repairs – we can make your vehicle healthy again. Whether you have owned your Subaru for a long time, or have recently acquired one, bring it to our San Carlos auto repair shop – we will keep your vehicle in peak condition. Call us to make an appointment, or you can make an appointment online, on our website.
