✅ Key Features & Benefits
| Feature / Benefit | What It Means / Why It’s Useful | ||
|---|---|---|---|
| Anti-freeze / anti-boil protection test | Helps you know whether coolant will properly protect against freezing in cold weather or overheating/boiling in hot conditions.
|
||
| Measures coolant concentration / density | A more concentrated coolant offers better protection — the tester shows if coolant is diluted (e.g. too much water), which weakens protection. | ||
| Visual inspection for rust, sediment, debris | Over time coolant can accumulate rust or particles — the tester’s clear chamber lets you see this, so you can decide if a coolant flush is needed. | ||
| Universal compatibility with ethylene/ glycol coolants | Works with most common coolant types (ethylene-glycol based), not just one brand — making it versatile across vehicles. | ||
| Simple, fast, DIY-friendly | No special tools or skills required: draw coolant, read the gauge, inspect visually. Good for car-owners doing maintenance at home. |
