DISCUSSION:
Some owners have expressed interest in using engine coolants made with propylene glycol instead of ethylene glycol due to its lower toxicity and
resultant reduced hazards to children and animals. Based on recent test data, most owners should not experience significant effects on cooling system
performance when using propylene glycol based coolant. The use of national brand propylene glycol based engine coolant that meets the same Chrysler
ethylene glycol specification of MS-7170 (or equivalent ASTM D5216) is acceptable for Chrysler built vehicles.
NOTE:
ANTIFREEZE SOLD FOR PROTECTING PLUMBING ETC. (RV ANTIFREEZE) IS NOT A SUITABLE ENGINE COOLANT.
However, owners should be discouraged from changing their engine coolant prior to the regularly scheduled maintenance period. Prematurely changing
engine coolant unnecessarily adds to the risk of environmental exposure.
Sufficient freeze protection for the region should be maintained. However, do not use more than a 55% solution (-35 F, -37 C). Use the chart that
accompanies the propylene glycol coolant, since a higher concentration is required to obtain the same freeze points as ethylene glycol coolant. If the
temperatures for your region fall below this, use ethylene glycol coolant.
Under severe driving conditions (towing a trailer in hot weather etc.) there may be a slight loss in cooling performance. If this is noticed, the system
should be changed back to ethylene glycol coolant.
