Why Fluid Flushes Matter More Than You Think
Why Fluid Flushes Matter More Than You Think

Most drivers know about oil changes — but what about the other fluids in your car? Transmission fluid, coolant, and brake fluid often get ignored, yet they’re just as critical to your vehicle’s performance and safety. At Car Aid Auto Repair, we help Metro Detroit drivers protect their investment with routine fluid flushes that keep cars running like new.
⚠️ What Happens If You Skip Fluid Flushes
- Transmission fluid: Dirty fluid causes slipping gears, overheating, and transmission failure.
- Coolant: Old coolant loses its ability to regulate engine temp, leading to overheating or cracked engine blocks in Michigan winters.
- Brake fluid: Absorbs moisture over time, causing spongy brakes and dangerous stopping distances.
- Power steering fluid: Breaks down and leads to stiff or noisy steering.
🛠️ How Often Should You Flush Fluids?
- Transmission fluid: Every 30,000–60,000 miles
- Coolant: Every 2–3 years
- Brake fluid: Every 2 years (or as moisture levels rise)
- Power steering fluid: Every 2–3 years
At Car Aid, our ASE-certified technicians check fluid condition during every inspection and give you honest recommendations — no upselling, just what your car actually needs.
💰 Why It Pays Off
- A $150 transmission flush can prevent a $3,000 rebuild.
- A $100 coolant service saves you from a $4,000 engine replacement.
- A $120 brake fluid flush ensures your $600 brake job lasts longer.
