Essential Fluids to Check Before Your Road Trip

Nothing ruins a road trip faster than an overheated engine or a failing transmission. Your car relies on several key fluids to keep everything running smoothly, and neglecting them can lead to costly repairs or even a breakdown in the middle of nowhere.

Before you hit the open road, take a few minutes to check these essential fluids—or better yet, let a Repco Authorised Service technician do it for you as part of a full log book service.

Engine Oil – The Lifeblood of Your Car
Oil lubricates your engine’s moving parts, reducing friction and preventing wear. Low or dirty oil can cause overheating and serious engine damage.

Check the level using the dipstick and top up if needed.
Inspect the colour—clean oil should be golden brown, not dark and sludgy.
Stick to your service schedule—if your oil is due for a change, don’t wait.

Coolant – Keep Your Engine Cool Under Pressure
Long drives put extra strain on your engine, and without proper cooling, you risk overheating

Check coolant levels in the reservoir and top up if needed.
Inspect for leaks—puddles under your car could mean trouble.
Ensure the right coolant mix—water alone won’t cut it.

Transmission Fluid – Smooth Shifting for the Long Haul
Your transmission is one of the most expensive parts of your car to repair, so keeping its fluid in check is crucial.

Check the fluid level and colour—it should be bright red and free of debris.
Top up if low, but never overfill.
Watch for warning signs—slipping gears or delayed acceleration mean it’s time for a professional check.

Brake Fluid – Because Stopping is Just as Important as Going
Strong, responsive brakes are essential for road trip safety.

Ensure the fluid is at the correct level—low fluid could indicate worn brake pads or a leak.
Check for discolouration—dirty fluid affects braking performance.
If your brakes feel soft or spongy, get them inspected immediately.
