WATER QUALITY FOR MIXING WITH COOL-
ANT CONCENTRATE

Engine  coolants  are  a  combination  of  three  chemical 

components: ethylene glycol (EG) or propylene glycol (PG) 

antifreeze, inhibiting coolant additives, and quality water.

Water quality is important to the performance of the 

cooling system. Deionized or demineralized water is 

recommended for mixing with ethylene glycol and 

propylene glycol base engine coolant concentrate.

All water used in the cooling system should meet the 

following minimum specifications for quality:

Chlorides

<40 mg/L

Sulfates

<100 mg/L

Total solids

<340 mg/L

Total dissolved I hardness

<170 mg/L

pH

5.5—9.0

 

IMPORTANT!

Do not use bottled drinking water because it often con-

tains higher concentrations of total dissolved solids.

Freeze Protection

The relative concentrations of glycol and water in the en

-

gine coolant determine its freeze protection limit.

Ethylene Glycol

Freeze Protection Limit

40%

-24°C (-12°F)

50%

-37°C (-34°F)

60%

-52°C (-62°F)

Propylene Glycol

Freeze Protection Limit

40%

-21°C (-6°F)

50%

-33°C (-27°F)

60%

-49°C (-56°F)

DO  NOT  use  a  coolant-water  mixture  greater  than  60% 

ethylene glycol or 60% propylene glycol.

TESTING COOLANT FREEZE POINT

The  use  of  a  hand-held  coolant  refractometer  is  the 

quickest, easiest, and most accurate method to determine 

coolant freeze point. This method is more accurate than 

a test strip or a float-type hydrometer which can produce 

poor results.

A coolant refractometer can be used to provides an eco-

nomical solution to accurate freeze point determination 

in the field.

To use this tool:

1. 

Allow cooling system to cool to ambient tempera-

tures.

2. 

Open heat-exchanger cap to expose coolant.

3. 

With the included dropper, collect a small coolant 

sample.

4.  Open the lid of the refractometer, place one drop of 

coolant on the window and close the lid.

5.  Look through the eyepiece and focus as necessary.

6. 

Record the listed freeze point for the type of coolant 

(ethylene  glycol  coolant  or  propylene  glycol)  being 

tested.
