A Guide to the Engine Coolant Thermostat for the 2014-2015 Nissan Rogue Select
Understand, diagnose, and choose the right replacement engine thermostat for your Rogue Select.
- A failing thermostat most often causes overheating (stuck closed) or an engine that runs too cool with a P0128 code (stuck open).
- Never drive a vehicle that is actively overheating; pull over immediately to prevent engine damage.
- For this part, using an OEM or a high-quality aftermarket brand like Gates or Beck Arnley is recommended for reliability.
- The replacement is a moderately difficult DIY job, but requires draining and refilling the coolant.
Is Your Rogue Select's Thermostat Failing?
A thermostat is a simple part, but when it fails, it can cause noticeable problems. Thermostats typically fail in one of two ways: stuck open or stuck closed. Both conditions can affect your engine's performance and health.
Common Symptoms of a Bad Thermostat
🎬 Watch: 7 common symptoms of a failing thermostat- Engine Overheating: If the thermostat is stuck closed, it traps coolant in the engine, preventing it from reaching the radiator. This is the most serious symptom and can lead to severe engine damage if not addressed immediately.
- Engine Not Warming Up / Check Engine Light (P0128): A thermostat stuck open allows coolant to circulate constantly. This prevents the engine from reaching its proper operating temperature, especially in cooler weather. This condition will almost always trigger the Check Engine Light with a P0128 trouble code.
- No Heat from Vents: If the engine isn't getting hot enough because the thermostat is stuck open, the coolant flowing to your heater core won't be hot enough to warm the cabin.
- Temperature Gauge Fluctuates: The needle on your temperature gauge may swing from cool to hot erratically, indicating the thermostat is struggling to regulate temperature.
Warning: Do Not Drive an Overheating Engine
If your temperature gauge is in the red or you see steam from the engine, pull over immediately and shut off the vehicle. Driving an overheated engine for even a few minutes can cause catastrophic damage.
Known Issues, Recalls, or Service Bulletins
Based on available data, there are no specific recalls or technical service bulletins (TSBs) from Nissan or the NHTSA for the engine coolant thermostat on the 2014-2015 Rogue Select model. Problems with this part are generally due to normal wear and tear over time.
Choosing the Right Aftermarket Thermostat
While an OEM (Original Equipment Manufacturer) thermostat from a Nissan dealer is always an option, quality aftermarket parts offer a reliable and cost-effective alternative. For a critical part like a thermostat, it's wise to stick with reputable brands.
- Tier 1 / OE-Equivalent Brands (Beck Arnley, Gates): These brands have a strong reputation for producing parts that meet or exceed original specifications. Beck Arnley specializes in sourcing parts from OEM suppliers, and Gates is a leader in cooling system components. Choosing from this tier provides a good balance of quality and value.
- Tier 2 / Standard Replacement Brands (Motorad, Calorstat, Facet): These are widely available and offer a functional, budget-friendly solution. While generally reliable for daily driving, some professional mechanics prefer OEM or Tier 1 brands for maximum longevity.
Pro Tip: Replace the Gasket
Always replace the thermostat gasket or O-ring when you replace the thermostat itself. Most new thermostats come with a new gasket included. This ensures a proper seal and prevents coolant leaks.
Cost to Replace a Rogue Select Thermostat
The cost can vary based on the part brand and local labor rates. The replacement is a moderately difficult job that takes a professional about 1.5 to 2.5 hours.
| Item | Estimated Cost |
|---|---|
| New Aftermarket Thermostat | $14 - $58 |
| New OEM Thermostat | $40 - $90 |
| Shop Labor | $150 - $300 |
| Total Estimated Cost (Aftermarket Part + Labor) | $164 - $358 |
Frequently Asked Questions
What is a P0128 trouble code? 🎬 See how to diagnose and fix a P0128 fault code
The P0128 code means "Coolant Temperature Below Thermostat Regulating Temperature." The engine's computer expects the coolant to reach a certain temperature within a set time. If it doesn't, usually because the thermostat is stuck open, it triggers this code.
Can I replace the thermostat myself? 🎬 Watch this step-by-step guide to replacing your Rogue's thermostat
For a DIYer with some experience, this is a manageable job. It requires draining the cooling system, accessing the thermostat housing (usually on the lower side of the engine), and having the right tools like sockets and pliers. If you are not comfortable working with the cooling system, it's best to leave it to a professional.
Is an OEM thermostat better for my Rogue Select?
OEM thermostats are designed specifically for your vehicle and have a proven track record of reliability. However, top-tier aftermarket brands like Gates or Beck Arnley are widely considered to be just as reliable and are a great alternative.
What happens if I ignore a bad thermostat?
Ignoring a thermostat stuck closed will lead to overheating and likely severe engine damage. Ignoring one stuck open will cause poor fuel economy, reduced heater performance, and can lead to increased long-term engine wear and failed emissions tests.
