This TSB article describes Ford Motor Company’s position on the use of propylene glycol-based engine coolants.
Ford Motor Company does not recommend nor endorse the use of engine coolants made with propylene glycol in Ford vehicles. Ford Motor Company currently recommends the use of ethylene glycol-based engine coolants.
Published information suggests that engine coolants made with propylene glycol may provide engine cooling performance equivalent to engine coolants made with ethylene glycol. However, different brands of engine coolant provide varying corrosion protection for the cooling system. Ford does not have performance data for the multitude of engine coolants available in the aftermarket and therefore cannot recommend the use of any coolant except those sold by Ford Customer Service Division. Consult the vehicle’s Owner’s Guide to determine the appropriate Ford Customer Service Division coolant for the vehicle.
Furthermore, claims of toxicological and environmental advantages of propylene glycol over ethylene glycol may be misleading. When significant new information is developed, Ford will review this policy.
Ford Motor Company specifications recommend that vehicles be maintained using certain ethylene glycol-based engine coolants. Those specifications do not refer to engine coolants made with propylene glycol. Although the Ford New Vehicle Limited Warranty is not automatically voided upon the use of a coolant made with propylene glycol, if such use results in damage to the vehicle or its components, the cost of repairing the damage would not be covered by the Ford New Vehicle Limited Warranty.
