The 2017 Jeep Wrangler JK is a versatile and iconic SUV designed for both adventure and daily driving. To keep its powerful engine running smoothly and efficiently, maintaining the cooling system is crucial. A key part of this is knowing the coolant capacity, ensuring you use the correct type and quantity during maintenance. Let’s explore everything you need to know about the coolant system for the 2017 Jeep JK.
Coolant Capacity by Engine Type
The 2017 Jeep Wrangler JK comes with two engine options, each with a specific coolant capacity:
- 3.6L Pentastar V6 Engine
- Coolant capacity: 14 quarts (13.25 liters)
- 2.8L Diesel Engine (if applicable)
- Coolant capacity: 10.2 quarts (9.7 liters)
Accurately refilling the coolant to the appropriate level is essential for optimal engine performance and to prevent overheating or damage.
The Importance of Coolant in Your Jeep Wrangler JK
Coolant, also known as antifreeze, plays a vital role in regulating your engine’s temperature. It prevents the engine from overheating in the summer and freezing in the winter. Additionally, coolant protects internal components from corrosion, ensuring the longevity of your Jeep’s engine and radiator.
Recommended Coolant Type
For the 2017 Jeep Wrangler JK, it is important to use the correct coolant type to maintain system efficiency. Jeep recommends using Mopar HOAT (Hybrid Organic Acid Technology) Coolant or equivalent, which is typically pink or orange in color. This type of coolant provides long-lasting protection for the cooling system and is designed to meet the specific needs of Jeep’s engine designs.
- Coolant Specification: Mopar 10-Year/150,000-Mile Coolant (OAT)
- Mixture: A 50/50 blend of coolant and distilled water is ideal for most climates. This ratio ensures effective temperature regulation and corrosion protection.
When to Check and Refill Coolant
Regular maintenance is key to keeping your 2017 Jeep Wrangler JK in top condition. Here are some tips:
- Routine Checks: Inspect the coolant level in the reservoir every 3,000 miles or as part of routine maintenance.
- Signs of Low Coolant: Look for warning signs such as the engine temperature gauge rising, coolant leaks under the vehicle, or visible low levels in the reservoir.
- Seasonal Maintenance: Perform a coolant check before extreme weather conditions, ensuring the mixture is adequate for the season.
- Flushing the System: Jeep recommends a coolant flush every 100,000 miles or 5 years, whichever comes first, to remove contaminants and maintain system efficiency.
Steps to Refill the Coolant
Refilling the coolant in your 2017 Jeep Wrangler JK is a straightforward process, but it requires care to avoid air pockets in the system:
- Cool Down: Ensure the engine is completely cool before opening the radiator cap to prevent burns.
- Drain Old Coolant: If flushing the system, drain the old coolant completely using the radiator drain plug.
- Mix Coolant: Prepare a 50/50 mixture of Mopar coolant and distilled water.
- Refill Slowly: Pour the coolant mixture into the radiator until full. Top off the reservoir to the “FULL” line.
- Bleed the System: Start the engine with the heater on high to circulate coolant and remove trapped air.
- Check Levels: After the engine cools again, recheck the levels and top off if necessary.
Common Coolant System Issues
Even with proper maintenance, issues can arise in your Jeep’s cooling system. Watch out for:
- Leaking Coolant: Puddles under the vehicle could indicate a leak in the radiator, hoses, or water pump.
- Overheating Engine: This could result from low coolant levels, trapped air, or a malfunctioning thermostat.
- Discolored Coolant: Rusty or murky coolant may indicate corrosion or contamination, requiring a system flush.
Addressing these problems early can save you from costly repairs and keep your Jeep running reliably.
Conclusion
Maintaining the cooling system of your 2017 Jeep Wrangler JK is essential for its performance and longevity. Understanding its coolant capacity, using the recommended Mopar HOAT coolant, and performing regular checks and flushes will ensure your Jeep is always ready for the road ahead. Whether you’re traversing trails or tackling the daily commute, a well-maintained cooling system keeps your Jeep cool and your adventures uninterrupted.
