Coolant Analysis

Coolant Analysis Service

Our Coolant Analysis service tests your coolant for: levels of contamination, system wear and its chemical make-up. These tests (detailed below) are performed in laboratory conditions and the findings, along with any recommendations or required actions, will be detailed to you in a comprehensive report.

The FA-ST Complete (UK) Coolant Analysis & Sampling Kit (COOLKIT1) - featured below - is perfect for use to submit your coolant samples to us. The kit can be used with all coolants and comes with a pre-paid Jiffy bag and return address label, and is inclusive of the coolant analysis service.

Please note the pre-paid Jiffy bag and return address label are not included in our International Coolant Analysis & Sampling Kit (OMKCOOL).

Coolant Analysis Tests Performed

Contamination Testing

Contamination testing is split into a number of different individual test. We will perform:

Glycol Volume Testing

Glycol Test determines the presence of ethylene glycol used in coolant.

Solid Volume Testing

Total Dissolved Solids examines the combined content of all inorganic and organic substances contained in Coolant.

Sediment Testing

Sediment tests determine the amount of free sediment in the coolant.


This includes the colour and to visually to see whether the coolant is in good clear condition.

System Wear Testing

The Ferrous Wear Index gives an indication of the total measure of Iron (regardless of size) in the sample. This technique is used to determine early component wear.

Chemistry Testing

Foaming Testing

Foaming can result from excessive agitation, improper fluid levels, air leaks, contamination or cavitation - the pitting or wearing away of a solid surface as a result of the collapse of a vapour bubble. Foaming can cause sluggish operation, air binding in pumps and tank or a sump overflow.

pH Testing

pH is a measure of the coolant's acidity or alkalinity. Whereas a coolant's neutralization number is related to the quantity of acid- or base-forming materials in a solution, pH indicates their intensity. Coolant pH range should remain between 7.5 and 11 to provide adequate corrosion protection.

Resistivity Testing

the resistivity of a liquid is a measure of its electrical insulating properties under conditions comparable to those of the test. High resistivity reflects low content of free ions and ion -forming particles and normally indicates a low concentration of conductive contaminants.

Rust Testing

This test identifies any rust within the coolant indicating lack of rust inhibitor.

Freezing Point Testing

Tests what point the coolant freeze to ensure it is able to carry out the job it is required to do.

Nitrite Testing

Nitrite is an inhibitor for cast iron, steel and liner cavitation protection. Excessive levels can lead to solder corrosion, precipitate formation and water pump failure.
