Why Fluid Inspections Matter For Your Vehicle
Your car depends on more than just gas to keep going. Beneath the hood and underneath the frame are several essential fluids in your car that help power systems, cool down parts, and prevent wear. These fluids need to be checked and replaced regularly to ensure your car runs smoothly. At Larson’s Automotive in San Antonio, our technicians offer complete fluid inspections to keep your vehicle in top condition.
What Fluids Are We Talking About?
Modern cars rely on several different types of fluids. Each one plays an important role in protecting moving parts, powering systems, or maintaining safety. These include:
- Engine oil
- Brake fluid
- Transmission fluid
- Coolant (also known as antifreeze)
- Power steering fluid
- Windshield washer fluid
Neglecting to check even one of these could lead to poor performance or damage over time. That’s why fluid inspections should be a regular part of your car’s maintenance routine, especially as your car approaches 50,000 miles.
Checking Your Engine Oil
Your engine oil keeps the engine lubricated and cools down internal components. During a fluid inspection, we check the fluid level, add oil if it’s low, and look for signs of contamination or a burnt smell.
If you check it at home, make sure to:
- Pull out the dipstick.
- Wipe it clean.
- Reinsert and remove it again to check the level and condition.
If the level is low or the oil looks dirty, it’s time for a change.
Brake Fluid: A Safety Essential
Your brake system relies on hydraulic pressure, and that pressure comes from brake fluid. Without it, your car won’t stop properly. To stay safe, check the brake fluid level and locate the brake fluid reservoir under the hood (usually near the firewall). The fluid should be at the proper level and a clear or light yellow color.
Dirty or low brake fluid can be dangerous. At Larson’s, we’ll let you know if it’s time for a replacement to protect you and your passengers.
Engine Coolant (Antifreeze)
Coolant—also known as antifreeze—is what helps ensure the engine doesn’t overheat or freeze. It flows through the radiator and engine block, keeping temperatures in check. During our inspection, we look at the coolant level, top it up if needed, and make sure the mixture is right (usually a 50/50 mix of water and antifreeze).
It’s important to use the type specified for your vehicle, as using the wrong kind can damage the cooling system.
Power Steering Fluid Check
Your power steering system helps you turn the wheel smoothly. If the fluid gets low, steering becomes harder and can wear out the system. We’ll check that the fluid is full and in good condition. If it looks dark or has a burnt smell, it may need a flush.
Transmission Fluid
Transmission fluid keeps your gears shifting smoothly. Some cars have sealed transmissions, while others allow you to check them with a dipstick. If your car has one, bring your transmission fluid with a dipstick to us—we’ll check the level and quality. Transmission fluid should be red or pink; brown or burnt-smelling fluid means it’s time to service.
Washer Fluid And Reservoirs
It may not be critical to your engine, but windshield washer fluid is essential for visibility. We’ll inspect the washer fluid reservoirs, refill them, and make sure the system sprays properly. It’s a small step that makes a big difference during bad weather or dirty road conditions.
When Should You Get A Fluid Inspection?
A full fluid check should be done:
- During every oil change
- Before long trips
- Every 6 months or 5,000 miles
- At key milestones like 50,000 miles
