Phoenix Systems Brake & Coolant Test Strips — 100 Double-Ended Strips, Dual-Purpose Kit with Customer Cards

Phoenix Systems 100 Double-Ended Brake & Coolant Test Strips are a shop-ready tube of 100 dual-purpose test strips that quickly evaluate both brake fluid and engine coolant for routine inspections and customer reporting.

Designed for independent repair shops, service departments, and fleet maintenance teams, this single compact kit gives technicians a repeatable, easy visual method to assess brake and cooling system fluid condition. Each strip is double-ended — one tip evaluates brake fluid using Phoenix Systems' patented copper-detection approach, while the opposite tip tests coolant against common industry guidelines. The metal tube contains 100 strips plus 100 customer-facing rating cards so shops can document results and explain recommended next steps to drivers.

How do I perform a brake fluid test with these strips?

Testing brake fluid is straightforward and intended for in-service inspections. Dip the brake-fluid end into the reservoir, gently agitate to remove air bubbles, wait the specified reaction time, and then compare the strip color to the supplied chart to determine if the fluid is degrading.

• Dip only the brake end into the fluid reservoir.
• Shake lightly to ensure contact and disperse contaminants.
• Read color match after approximately 90 seconds.
• Use the included color chart and customer cards to record results.

What does the coolant end check and when should I use it?

The coolant end evaluates diluted coolant condition and inhibitor levels according to established MAP, ASL, and ASTM reference values. It’s designed for use on coolant that is properly mixed and below 140°F; this helps confirm protection levels and service timing without specialized lab equipment.

• Only test coolant that’s correctly diluted and under 140°F.
• Dip the coolant tip, shake gently, and read after roughly 60 seconds.
• Compatible with common coolant chemistries, including HOAT and OAT types.
• Compare to the included guide to determine next steps.

Which fluids and vehicles can these strips be used for?

The strips accommodate the wide variety of brake and cooling fluids found in modern shops. They read DOT 3, DOT 4, and DOT 5.1 brake fluids, including many synthetic low-viscosity formulas, and they test all common coolant colors and families when correctly diluted. Note: Do not use the strips to test DOT 5 silicone brake fluid or undiluted concentrate coolant.

• Works with DOT 3, DOT 4, DOT 5.1 brake fluids (not DOT 5 silicone).
• Tests OAT, HOAT, and other common coolant types when diluted.
• Suitable for cars, trucks, and fleet vehicles in routine inspections.
• Useful for shops performing quick checks during service appointments.

How long do the strips stay accurate, and what’s in the kit?

The sealed metal tube with desiccant helps preserve strip performance once opened, supporting reliable testing for high-volume environments. The kit bundles 100 double-ended strips plus 100 customer rating cards so technicians can present documented results along with recommendations.

• One metal tube contains 100 dual-ended test strips.
• Includes 100 printable customer rating cards for transparency.
• Desiccant-lined container helps maintain shelf life after opening.
• Certified under MAP and BAR standards and built on copper-detection technology.

Who is this for? Phoenix Systems' 100 Double-Ended Brake & Coolant Test Strips are built for automotive shops, dealership service bays, quick lube centers, and fleet maintenance teams that need a fast, repeatable way to evaluate brake fluid and coolant on-site. If you want a simple visual test that technicians can perform during inspections and that service writers can present to customers as documented evidence, this kit provides a practical, shop-friendly solution without requiring lab equipment.
