How To Check Your Fluid Levels Between Services

How To Check Your Fluid Levels Between Services

Keeping your car running smoothly isn’t just about regular servicing - it’s also about what you do in between. One of the simplest and most effective habits you can adopt as a car owner is checking your vehicle’s fluid levels. Fluids are the lifeblood of your car, and monitoring them regularly helps prevent costly breakdowns, keeps your vehicle safe, and extends its life.

Below, Pearson Automotive had a guide on which fluids to check, how to check them, and why it matters.

Engine Oil

Engine oil lubricates moving parts, reduces friction, and helps regulate temperature. Low or dirty oil can cause severe engine damage.

How to check:

1. Park on level ground and turn off the engine.
2. Pull out the dipstick, wipe it clean, then reinsert and remove again.
3. Check that the oil level is between the “min” and “max” marks.
4. If it’s low, top up with the recommended oil for your vehicle.

Tip: If the oil looks dark and gritty, it may be time for a change.

Coolant

Coolant regulates engine temperature and prevents overheating. Without enough coolant, your engine can overheat and suffer expensive damage.

How to check:

• With the engine cold, locate the coolant reservoir.
• The side of the tank should have “low” and “full” markers.
• Ensure the coolant sits between these marks.
• Top up with the correct coolant mixture if needed.

Important: Never open the radiator cap when the engine is hot.

Transmission Fluid

Transmission fluid keeps gears shifting smoothly and protects internal components.

How to check:

• Some vehicles have a dipstick similar to engine oil; others may require professional inspection.
• If accessible, check the fluid when the engine is warm and running, with the gear in park.
• Fluid should be a bright red colour. If it looks dark or smells burnt, book a service.

Brake Fluid

Brake fluid is critical for safe stopping. Low levels can indicate worn brake pads or a leak in the system.

How to check:

• Locate the brake fluid reservoir under the bonnet.
• The fluid should be between the minimum and maximum lines.
• If it’s low, top up with the correct type - but also have your brakes inspected as it could point to a bigger issue.

Power Steering Fluid

This fluid keeps steering smooth and responsive. Low levels may cause stiffness or whining noises when turning.

How to check:

• Look for the power steering fluid reservoir.
• Check the level against the marks and top up if needed.
  
  

Washer Fluid

It may not affect performance, but washer fluid is essential for visibility and safe driving.

How to check:

• Open the washer fluid reservoir, usually marked with a windscreen symbol.
• Top it up with washer fluid or a mix of water and cleaning solution.

A quick fluid check once a month can save you from unexpected issues and keep your car safe on the road. If you’re unsure about any of these checks, or notice frequent drops in fluid levels, it’s best to get your vehicle inspected by a qualified mechanic, like those at Pearson Automotive.
