Prowler V6-3.5L VIN G (1999)
Coolant: Fluid Type Specifications
GENERAL INFORMATION
Performance is measurable. For heat transfer pure water absorbs 1 btu for each degree of temperature rise for each pound of water. This formula is
altered when necessary additives to control boiling, freezing, and corrosion are added as follows:
-
Pure Water (1 btu) boils at 100°C (212°F) and freezes at 0°C (32°F).
-
100 Percent ethylene glycol (0.7 btu) can cause an engine to run hot, cause detonation, and will freeze at -22°C (-8°F).
-
50/50 Ethylene Glycol and Distilled Water (0.82 btu) is the recommended combination that provides a freeze point of -37°C (-35°F). The
radiator, water pump, engine water jacket, radiator pressure cap, thermostat, temperature gauge, coolant sensor and heater are all designed for
50/50 ethylene glycol.
-
Where required, a 56 percent glycol and 44 percent water mixture will provide a freeze point of -46°C ( -50°F ).
NOTE: Richer mixtures cannot be measured with field equipment and can lead to problems associated with 100 percent glycol. If there is doubt
that the coolant mixture is to rich for field equipment to measure, put a sample in a clean container. Add exactly the same amount of water and
retest. If the coolant in the vehicle is 100% antifreeze, the diluted sample will read 50%. If the coolant in the vehicle was 70% antifreeze and 30%
water, the diluted sample will read as 35%, etc.
SELECTION AND ADDITIVES
The use of aluminum cylinder heads, intake manifolds, and water pumps requires special corrosion protection. Mopar Antifreeze or their
equivalent are recommended for best engine cooling without corrosion. When mixed only to a freeze point of -37°C (-35°F) to -59°C (-50°F). If it
looses color or becomes contaminated, drain, flush, and replace with fresh properly mixed solution.
CAUTION: Do not use well water, or suspected water supply in cooling system. A 50/50 ethylene glycol and distilled water mix is
recommended.
