Dodge 2009 Caravan - Manual (Page 455)

CAUTION! (Continued)
• This vehicle has not been designed for use with
Propylene Glycol-based engine coolant (anti-
freeze). Use of Propylene Glycol-based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (antifreeze) that allows extended maintenance
intervals. This engine coolant (antifreeze) can be used up
to five years or 102,000 miles (170 000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same
engine coolant (antifreeze) throughout the life of your
vehicle. Please review these recommendations for using
Hybrid Organic Additive Technology (HOAT) engine
coolant (antifreeze).
When adding engine coolant (antifreeze), a minimum
solution of 50% recommended MOPAR௡ Antifreeze/
Coolant Five Year/100,000 Mile Formula HOAT (Hybrid
Organic Additive Technology), or equivalent, in water
should be used. Use higher concentrations (not to exceed
70%) if temperatures below Ϫ34°F (Ϫ37°C ) are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant (antifreeze)
solution. The use of lower quality water will reduce the
amount of corrosion protection in the engine cooling
system.
