Locating the Thermostat on a 2014 Infiniti Q50
The thermostat on a 2014 Infiniti Q50 is an integral component of the engine’s cooling system, responsible for regulating coolant flow based on engine temperature. Finding its exact location requires understanding the layout of the engine bay and the cooling system pathways.
Typically, the thermostat is housed near the engine block, at the junction where the upper radiator hose connects to the engine. On the Infiniti Q50, this is generally found on the front side of the engine, close to the cylinder head. The thermostat housing is a metal or plastic casing that bolts to the engine, enclosing the thermostat itself.
To locate the thermostat:
- Open the hood and secure it with the prop rod.
- Identify the upper radiator hose, which is a large rubber hose running from the radiator to the engine.
- Trace this hose to where it connects to the engine block; the connection point is the thermostat housing.
- The housing will have a cover held by bolts, which when removed, exposes the thermostat.
It is important to ensure the engine is cool before attempting to locate or remove the thermostat to avoid burns from hot coolant.
Tools and Equipment Needed for Accessing the Thermostat
Accessing the thermostat on the Infiniti Q50 requires specific tools to safely and efficiently remove the housing and replace the component if necessary. Having the right tools on hand streamlines the process and reduces the risk of damaging parts.
Essential tools include:
- Socket wrench set (including extensions and universal joints)
- Screwdrivers (Phillips and flathead)
- Pliers (needle nose and regular)
- Drain pan for catching coolant
- Gasket scraper or sealant remover
- Replacement thermostat and gasket
- Torque wrench (for correct reassembly torque specifications)
- Clean rags or shop towels
- Safety gloves and eye protection
Steps to Access and Inspect the Thermostat
Once the thermostat location is identified and tools are ready, proceed with careful steps to access and inspect the thermostat:
- Drain Coolant: Place a drain pan underneath the radiator drain plug and partially drain the coolant to below the thermostat housing level to prevent spillage.
- Remove Components: Depending on engine configuration, you may need to remove components obstructing access, such as the air intake duct or engine covers.
- Disconnect Upper Radiator Hose: Loosen the hose clamp with pliers or a screwdriver and carefully detach the upper radiator hose from the thermostat housing.
- Unbolt Thermostat Housing: Using the appropriate socket, remove the bolts securing the thermostat housing to the engine block.
- Remove Thermostat: Carefully lift the thermostat and note its orientation for proper reinstallation.
- Inspect Thermostat: Check for signs of wear, corrosion, or damage. The thermostat valve should be closed when cold and open when heated.
Thermostat Specifications and Operating Temperatures
Understanding the thermostat’s operating parameters helps in diagnosing cooling system issues and selecting the correct replacement part. The 2014 Infiniti Q50 uses a thermostat designed to open at a specific temperature to maintain optimal engine performance.

This temperature range allows the engine to reach optimal operating temperature quickly while preventing overheating by regulating coolant flow to the radiator.
Common Issues Related to Thermostat Location and Access
Accessing the thermostat on the Infiniti Q50 can sometimes present challenges, particularly due to the engine bay layout and surrounding components. Being aware of potential issues can save time and prevent damage.
- Limited Space: The engine bay on the Q50 is compact, requiring removal of nearby components like the air intake or battery bracket for better access.
- Corroded Bolts: Thermostat housing bolts may be corroded or seized due to exposure to coolant and engine heat.
- Coolant Spillage: Improper draining or disconnection of hoses can result in coolant spills, which are hazardous and require cleanup.
- Incorrect Reassembly: Misalignment of the thermostat or improper gasket installation can cause leaks or malfunction.
- Thermostat Orientation: Installing the thermostat upside down can lead to improper engine temperature regulation.
Proper preparation, including having a service manual and following recommended procedures, helps mitigate these issues effectively.
