Engine Coolant Antifreeze - Check
NOTICE: Over-concentration of antifreeze or use of high silicate antifreeze can cause engine damage.
Check the antifreeze concentration. Use a mixture of 50% water and 50% ethylene glycol or propylene

To check antifreeze concentration:
1. Place a drop of coolant on a refractometer window and shut the lid.
2. Look through the eyepiece and focus.
3. Record the freeze point protection for either ethylene glycol or propylene glycol coolants.
NOTICE: Antifreeze is essential in every climate.
