Engine Coolant
WARNING: This page is about a different car, the 2004 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Engine coolant contains monoethylene glycol and other constituents, which are toxic if taken internally and can be absorbed into the skin after prolonged contact.
Engine coolant concentration should be checked through the neck of the expansion tank with a hydrometer. The acceptable range of specific gravity (sg) of correctly balanced fluids is between 11.10 and 11.20 lbs/gal, which represents an engine coolant concentration between 40 percent and 55 percent. If the concentration falls below 40 percent there is insufficient low temperature protection and the corrosion resistance will be inadequate. In such cases the concentration must be brought back to specification.
The engine coolant should not be mixed with other coolant types. For cooling system top off, only use coolant which meets specification. For additional information, refer to SPECIFICATIONS .
