What type of coolant does a 2007 Dodge Nitro take?
The 2007 Dodge Nitro uses Dex-Cool extended-life HOAT coolant (orange). Use Mopar Dex-Cool or an equivalent HOAT coolant that meets Chrysler specifications, typically mixed 50/50 with distilled water unless the product is premixed.
Coolant type and specifications
Dex-Cool is a silicate-free, long-life coolant formulated for modern engines. For the Nitro, Chrysler/Dodge recommends Dex-Cool or an equivalent HOAT coolant that meets Chrysler specifications. The orange color identifies Dex-Cool, and you should avoid mixing it with conventional green coolant or other non-HOAT formulations.
Approved coolant options
Before listing options, note that only products labeled as Dex-Cool or HOAT coolant that explicitly meet Chrysler specifications are appropriate for the Nitro.
- Mopar Dex-Cool Extended Life Antifreeze/Coolant (orange)
- Equivalent HOAT coolant that explicitly meets Chrysler specifications (orange, silicate-free)
- Premixed 50/50 Dex-Cool or HOAT coolant in bottles designed for automotive cooling systems
Using the wrong type or mixing incompatible coolants can cause deposits, corrosion, or cooling-system issues. Always verify compatibility with your vehicle’s manual and use the recommended 50/50 mix unless the product is already premixed.
Notes on mixing and maintenance
When topping up or replacing coolant, ensure you use the correct formulation and avoid introducing contaminants. Do not dilute Dex-Cool with non-HOAT formulations, and never mix Dex-Cool with green or blue conventional coolant.
Replacement and maintenance steps
To perform a coolant refresh or top-up, follow these steps carefully.
- Park the vehicle on a level surface and let the engine cool completely before opening the cooling system.
- Relieve any pressure by slowly removing the radiator cap (when cool) and open the reservoir cap if present.
- Drain the old coolant from the radiator and engine block as applicable, then close the drain plug.
- Flush the system if recommended by the manual, then refill with a 50/50 mix of Dex-Cool or an equivalent HOAT coolant and distilled water.
- Replace the radiator cap, run the engine to operating temperature, and check for leaks and proper level. Recheck the coolant level when the engine is cool.
After a refill, monitor the system for air pockets or leaks and top off as necessary to maintain the correct level.
Important cautions and quick guidance
Key precautions to keep in mind when dealing with Dex-Cool HOAT coolant include:
- Use only Dex-Cool or an equivalent HOAT coolant that meets Chrysler specifications.
- Avoid mixing with green or traditional IAT coolant.
- Always add coolant to a cool engine to prevent scalding and pressure-related injuries.
- Dispose of old coolant at an approved facility; do not pour it down drains or onto the ground.
Following these guidelines helps maintain cooling-system performance and prevents damage to the Nitro’s engine components.
Summary
In short, a 2007 Dodge Nitro requires Dex-Cool extended-life HOAT coolant (orange), with Mopar Dex-Cool or an equivalent that meets Chrysler specifications. Use a 50/50 mix with distilled water unless premixed, follow the vehicle’s manual for service intervals, and handle and dispose of coolant safely. If you’re unsure, consult a dealer or qualified mechanic for confirmation and service.
