Automakers standardize coolant to protect the engine and cooling system, and Jeep's 2016 Grand Cherokee follows Chrysler’s Type 2 HOAT guidelines. The simplest way to ensure you’re using the correct product is to choose Mopar’s own Type 2 HOAT coolant, or an equivalent that explicitly meets Chrysler’s Type 2 HOAT specification.
In brief, the Grand Cherokee requires a HOAT (Hybrid Organic Acid Technology) coolant from Mopar, commonly sold as Extended Life Coolant in an orange formulation. It can be bought as a premixed 50/50 solution or as concentrate to dilute with distilled water, depending on your preference and service needs.
Understanding the specification for the 2016 Grand Cherokee
The 2016 Grand Cherokee spans multiple engines (for example, the 3.6L Pentastar, the 5.7L Hemi, and the 3.0L EcoDiesel). Across these variants, Chrysler/Jeep specifies a Type 2 HOAT coolant that is compatible with aluminum engine components and formulated to resist corrosion over the long term. Hoat stands for Hybrid Organic Acid Technology, designed to provide long-life protection and better performance in modern cooling systems.
Recommended coolant options
Below are options commonly accepted for the 2016 Grand Cherokee when following Chrysler’s Type 2 HOAT guideline. The list aims to balance authenticity with practical choices available at many auto parts stores.
- Mopar Extended Life Antifreeze/Coolant Type 2 HOAT (orange) — available as premixed 50/50 with distilled water, or as concentrate to mix on-site.
- Other brands that specifically state compatibility with Chrysler/Jeep Type 2 HOAT or Chrysler MS 9769 Type 2 coolant — ensure the product is silicate-free and suitable for aluminum engines.
- Do not use coolant formulas not labeled Type 2 HOAT or that are not explicitly compatible with Chrysler/Jeep engines (for example, some Dex-Cool or non-HOAT conventional formulas).
When in doubt, choose a coolant labeled Type 2 HOAT and guaranteed to be compatible with aluminum engines, and follow the bottle’s dilution instructions to achieve the correct 50/50 mixture if you’re using a concentrate.
Practical tips for replacement and maintenance
Before replacing coolant, consult the owner’s manual for the exact specification and service intervals. If you’re switching from one type of coolant to another, a thorough system flush is recommended. After filling, run the engine to operating temperature, bleed air as needed, check for leaks, and verify the coolant level once the system cools.
Maintenance reminders
Keep to the vehicle’s service schedule for coolant replacement and vehicle-specific guidelines. Using the correct Type 2 HOAT formulation helps protect the engine, radiator, and water pump, especially in hot climates or frequent stop-and-go driving.
Summary
The 2016 Jeep Grand Cherokee uses Mopar Extended Life Coolant Type 2 HOAT (orange), in premixed 50/50 form or as concentrate to dilute with distilled water. Use coolant that is explicitly labeled Type 2 HOAT and is compatible with aluminum engines; avoid non-HOAT or Dex-Cool-like formulas unless they clearly meet Chrysler’s Type 2 HOAT specification. For the exact match to your engine variant, consult the owner’s manual or a Jeep service representative.
