Sample Scheduling and Consistency
Sampling coolant at regular intervals under normal operating conditions can detect and prevent damage caused by:
- wear metals and contaminants
- imbalances in glycol to water ratio
- coolant additives
- breakdown
- excessive levels
- mixing and detrimental chemical combinations

Coolant Analysis Training Seminar - Now Available
| Basic Testing |
Advanced Testing |
| Recommended sampling interval for basic coolant analysis is every 250-500 hours of service (10-20 days). |
Recommended sampling interval for advanced coolant analysis is every 4th sample or about 4 months whichever comes first. |
Preparations:
Make sure:
- sample bottle is clean and free of contaminants.
- samples are drawn from consistent sample points.
- samples are labelled clearly.
If sampling water used in the coolant:
- run the water for at least one minute.
Procedures:
All Sampling Supplies Listed Are Available From The Fluid Life Corporation.
Sampling with a Suction Pump
Sampling with a suction pump draws coolant from the radiator. With the engine off and cool,
insert a clean piece of plastic tubing into the radiator or coolant reservoir that reaches about 6 inches into
the fluid. Screw the sample bottle firmly to the suction pump. Fill the bottle about 90% full (80ml).
Avoid taking a coolant sample from the bottom of the radiator or coolant reservoir. |
 |
Sampling with a Pushbutton Valve
Remove the protective cap and wipe the valve with a clean cloth.
Press the push button slowly to avoid a sudden burst of coolant.
Extract then discard the first 150 ml (5 ounces) of fluid to remove any debris from the valve.
Fill the sample bottle about 90% full (80ml). Seal the bottle tightly and wipe clean. |
 |
Sampling with a Probalyzer Valve
Wipe the valve with a clean, dry cloth. Slowly push the needle valve probe onto the sampling valve.
Please be cautious as coolant may be under pressure!. Discard about 150ml (5ounces) of the initial fluid
from the valve to make sure dirt and debris are removed. Fill the sample bottle about 90% full (80ml).
Seal the bottle tightly and wipe clean. |
