The 2014 Jeep Patriot uses Mopar Antifreeze/Coolant Type 2 (OAT) in a pre-diluted 50/50 blend with distilled water.
For the 2.0-liter and 2.4-liter engines used in this model year, Jeep specifies a Type 2 Organic Acid Technology coolant. If Mopar Type 2 isn’t available, you may choose a third‑party OAT coolant that is explicitly approved for Chrysler/Jeep applications and is silicate‑free. Do not use conventional green coolant or other non‑OAT formulas in this vehicle, and avoid mixing coolant types.
Official coolant specification
Jeep’s service literature and the owner’s manual specify Mopar Antifreeze/Coolant Type 2 (OAT) in a 50/50 premixed solution with distilled water. This is designed to protect the cooling system from corrosion and deposits over time.
To help you shop, here are acceptable options and guidelines:
- Mopar Antifreeze/Coolant Type 2 (OAT) – premixed 50/50
- Third‑party silicate‑free OAT coolants formulated for Chrysler/Jeep applications and labeled as compatible with Mopar/Chrysler engines
- Avoid using conventional green IAT coolant or any coolant with silicates; do not mix coolant types
Using one of these OAT coolants in a 50/50 mix will protect the cooling system and simplify maintenance. If you switch types, follow the manufacturer’s flushing recommendations to prevent chemical incompatibilities.
Maintenance tips and best practices
Here are practical guidelines for topping up and servicing the cooling system:
- Check the coolant level when the engine is cold; keep the reservoir between the low and full marks
- Use a 50/50 mix of the specified OAT coolant and distilled water; if you start with concentrate, mix it first before adding
- Top off with the same coolant type—do not mix different coolant chemistries
- If you notice leaks, overheating, or air in the system, have the cooling system serviced and bled according to the manual
- Refer to the owner’s manual for service intervals; Mopar Type 2 coolant is typically recommended on a multi‑year/maintenance schedule (e.g., around 5 years or 100,000 miles, depending on climate and use)
Bottom line: stick with a Chrysler/Jeep‑approved OAT coolant and a 50/50 mix, and follow the official service guidance to keep your cooling system performing reliably.
Summary
In short, a 2014 Jeep Patriot takes Mopar Antifreeze/Coolant Type 2 (OAT) in a pre‑diluted 50/50 blend with distilled water. If Mopar Type 2 isn’t available, choose a Chrysler/Jeep‑approved, silicate‑free OAT coolant and avoid mixing with non‑OAT or traditional green coolants. Always consult the owner’s manual for exact intervals and capacity, and use the same coolant type for topped‑offs or full exchanges.
