Coolant Test Strip 100-Pack - Determine When to Replace Automotive

In this review the Phoenix Systems 8001-B Coolant Test Strip is presented as a simple, scientific tool for DIY mechanics and shop technicians who need to know when to change engine coolant. The bottom line: it is most useful for anyone who wants clear, visual proof of coolant condition because the strips measure both pH and glycol percent in about 60 seconds, and come in a large 100-count aluminum-sealed container to keep results fresh. That reliability and ease of use make it a practical addition to routine maintenance checks.

Key Features

• Universal compatibility: Works with all coolant colors and formulations including conventional, long life, extended life, Dex-Cool and Low Tox, so users do not need separate strips.
• Quick visual test: Provides an easy to read 60 second result so a technician can make a rapid service decision without lab equipment.
• Measures pH and glycol: Gives both acidity and freeze/boil protection information to indicate corrosion risk and antifreeze effectiveness.
• Large fresh supply: One bottle contains 100 test strips sealed in an aluminum container with a molecular sieve in the lid to preserve accuracy over time.
• Practical guidance: Designed to be used on coolant diluted as it sits in the vehicle (generally 50/50) to deliver relevant, real-world results.

Who It's For

The ideal user is a DIY car owner, fleet manager, or independent shop technician who wants a low-cost, evidence-based way to determine coolant condition without guessing. Anyone who performs routine maintenance and prefers to see test proof before flushing or replacing coolant will find these strips useful.

People who should look elsewhere are those needing laboratory-grade analysis of every additive or trace contaminant, or anyone who will test coolant only in full concentrate; the product specifically requires proper dilution for accurate readings.

Pros & Cons

Pros

• Accurate, easy to read results for both acidity and glycol percentage that customers report as reliable.
• High value for money with 100 strips in a sealed container and molecular sieve for freshness.
• Works with many coolant types and colors, including orange Dex-Cool, reducing the need for multiple test types.

Cons

• Requires proper dilution (generally 50/50) to avoid incorrect readings, which adds a small step to testing.

Frequently Asked Questions

Do I test coolant straight from the radiator?
Test the coolant as it is in the vehicle, generally diluted 50/50; do not test full concentrate without proper dilution.

Will the strips work with orange Dex-Cool?
Yes, the strips are formulated to work with all coolant colors including Dex-Cool and Low Tox formulas.

How long do strips stay accurate?
Strips are packaged in an aluminum container with a molecular sieve in the lid to keep them fresh and accurate until used.
