Coolant Description
WARNING:
•
Keep hands, tools and clothing away from radiator cooling fan to help prevent personal injury. This fan is electric and can turn on whether engine is running or not. The fan can start automatically in response to ECM with ignition switch turned on.
•
To help avoid danger of being burned, do not remove degassing tank cap while engine and radiator are still hot.
Scalding fluid and steam can be blown out under pressure if cap is taken off too soon.
•
Check to make sure that engine coolant temperature is cold before removing any part of cooling system.
•
Also be sure to disconnect negative (–) cable from battery terminal before removing any part.
When the system cools down, the coolant is drawn back into the radiator.
The cooling system has been filled at the factory with a quality coolant that is a 50/50 mixture of water and ethylene glycol antifreeze.
This 50/50 mixture coolant solution provides freezing protection to –36 °C (–33 °F).
•
Maintain cooling system freeze protection at –36 °C (–33 °F) to ensure protection against corrosion and loss of coolant from boiling.
This should be done even if freezing temperatures are not expected.
•
Add ethylene glycol base coolant when coolant has to be added because of coolant loss or to provide added protection against freezing at temperature lower than –36 °C (–33 °F).
NOTE:
•
Alcohol or methanol base coolant or plain water alone should not be used in cooling system at any time as damage to cooling system could occur.
•
Coolant must be mixed with demineraled water or distilled water.
