Robinair Coolant Test Strips 50 Pack — Freeze Point & pH Dip-and-Read

Robinair 75134 Econo-Clean coolant test strips are a simple dip-and-read kit that measures freeze point and pH for ethylene and propylene glycol automotive coolants.

Keeping engine coolant within the right freeze/boil protection range and pH balance helps reduce corrosion and maintain heat transfer performance. The Robinair 75134 Econo-Clean pack contains 50 single-use strips in a labeled bottle with an easy color-key so technicians and DIYers can quickly interpret results for a wide range of vehicles including cars, trucks, SUVs, motorcycles, ATVs and snowmobiles.

How do these strips tell me the freeze point of my coolant?

Each strip reacts to the glycol concentration in the coolant and changes color to indicate an approximate freeze point. After dipping, you compare the strip’s color blocks to the bottle’s color chart to read the estimated freeze protection temperature.

• Dip strip into coolant for a few seconds, then remove and wait the specified reaction time.
• Match the stripe colors to the bottle’s freeze point key for a temperature estimate.
• Use the freeze point reading to determine if coolant needs topping or replacing.

Can these strips check different coolant types and vehicle applications?

Yes — the Econo-Clean strips are formulated to indicate results for both propylene glycol and ethylene glycol based coolants used in many vehicle types. They’re suitable for routine checks across automotive, light‑duty, and powersports applications.

• Works with ethylene and propylene glycol engine coolants.
• Appropriate for cars, trucks, SUVs, vans, motorcycles, ATVs and snowmobiles.
• Good for fleet, shop, or home garage preventative maintenance.

What does the pH result show and why is it useful?

The strips include a pH indicator to identify coolant acidity or alkalinity levels that can accelerate corrosion or degrade additives. Monitoring pH helps detect coolant that has aged or become contaminated so you can address potential cooling system damage early.

• pH reading highlights possible acidification from breakdown or contamination.
• Early pH shifts can indicate need for flushing or coolant replacement.
• Simple color-match on the bottle gives a quick go/no-go assessment for service.

How many tests are in a bottle and how should I store them?

The compact bottle contains 50 individual test strips, enough for multiple vehicles or recurring checks. Keep the strips sealed in the bottle and store in a cool, dry place away from direct sunlight to maintain accuracy.

• 50 single-use strips per bottle for routine monitoring.
• Resealable bottle protects unused strips from humidity and light.
• Store at room temperature; follow label instructions for best results.

Who is this for: The Robinair 75134 Econo-Clean pack suits professional technicians, independent mechanics, fleet managers and vehicle owners who want a low-cost, fast method to check coolant freeze protection and pH. It’s ideal for seasonal maintenance checks before winter or summer, for pre-trip inspections on powersports vehicles, and for shops that need a straightforward screening tool to decide when a full coolant service is required. The dip-and-compare process takes only moments, and the 50-strip supply keeps test costs low while helping you maintain cooling system reliability across many vehicle types.
