Phoenix Systems Coolant Test Strips 100-Pack — Dual-Read pH & Glycol, 60-Second Results

Phoenix Systems 8001-B Coolant Test Strips are a 100-count kit that quickly checks engine-coolant pH and glycol concentration so you can decide if coolant replacement is needed.

Keeping engine coolant within the right chemical range helps protect radiators, hoses, water pumps and other cooling-system components. The Phoenix Systems 8001-B test strips give clear, 60-second visual results for both pH and glycol percent and come sealed in an aluminum canister with a molecular-sieve lid to preserve freshness. Designed for use with diluted in-vehicle coolant (typically 50/50), these strips work with conventional, long-life, Dex-Cool and low-tox formulas and remove guesswork from maintenance decisions.

How quickly will I get a reliable result?

Each strip produces a two-parameter visual readout in about 60 seconds, so you can assess coolant condition nearly instantly. The test covers pH and glycol percentage, providing actionable data for service planning.

• Results visible in roughly one minute
• Dual-read strip checks pH and glycol concentration
• Color comparison chart provides immediate interpretation

Can I use these with any coolant color or type?

Yes — the Phoenix Systems strips are formulated to work across coolant chemistries and colors, including conventional, extended-life, Dex-Cool and low-tox formulations. They are intended to assess diluted coolant as it exists in the vehicle, not full-strength concentrate.

• Compatible with all coolant colors and major formulas
• Works with ethylene- and propylene-glycol based coolants
• Not designed for testing undiluted concentrate

How are the strips stored and kept accurate?

Strips are supplied in an aluminum container with a molecular-sieve insert built into the lid to absorb moisture and extend shelf life. This packaging approach keeps the test chemistry stable so each of the 100 strips delivers dependable readings when stored properly.

• Aluminum canister shields strips from light and moisture
• Molecular sieve in lid reduces humidity exposure
• Each bottle includes 100 individually usable strips

What is the correct way to test coolant with these strips?

Remove a small coolant sample from the vehicle’s system and use it as diluted in the cooling loop (commonly 50/50 coolant-to-water). Dip the strip, wait the instructed 60 seconds, then compare colors to the reference chart to determine pH and glycol percent. Do not test undiluted concentrate.

• Sample coolant as it is in the vehicle — typically 50/50
• Dip strip, wait ~60 seconds, compare to chart
• Use results as scientific evidence when planning service

Who this is for: Phoenix Systems 8001-B Coolant Test Strips are aimed at professional technicians, fleet managers, and DIY vehicle owners who want a fast, affordable way to verify coolant condition and glycol concentration. If you perform routine maintenance, diagnose overheating or corrosion concerns, or manage multiple vehicles, these strips provide a repeatable test method and documented proof to support coolant replacement decisions. They are not a substitute for laboratory analysis in complex failure investigations but are an effective first-line check to reduce risk and support timely service.
