Coolant Thermostat Housing

As a core component category in automotive engine cooling systems, the Coolant Thermostat Housing is a critical link ensuring engine temperature stability, and the Coolant Thermostat Housing products under JIATIAN have been widely recognized for their compliance with industry standards and reliable performance. With a 32,000-square-meter company area (26,000-square-meter factory area) and a complete R&D and processing system, JIATIAN integrates advanced equipment such as CNC fully automatic pipe bending machines and hydraulic internal forming machines into the production of Coolant Thermostat Housing, ensuring each product meets strict quality requirements.

1. Core Working Principle of Coolant Thermostat Housing
The Coolant Thermostat Housing is typically mounted on the engine block or cylinder head, and its core working logic is divided into two stages around the thermostat it houses:
Cold start stage: When the engine is in the cold start state, the thermostat remains closed under the Coolant Thermostat Housing's fixed protection. The coolant only circulates inside the engine (small cycle), which accelerates the engine's temperature rise and shortens the warm-up time.
Normal working stage: When the engine temperature reaches the preset threshold, the thermostat senses the temperature change and opens. The Coolant Thermostat Housing guides the high-temperature coolant to flow into the radiator (large cycle) for heat dissipation, and then guides the cooled coolant back to the engine, forming a closed loop to maintain the engine at an optimal working temperature.
JIATIAN has built a comprehensive laboratory to verify the matching degree between the Coolant Thermostat Housing and the thermostat in the R&D stage, ensuring the accuracy of temperature sensing and flow control.

2. Common Core Attributes of Coolant Thermostat Housing Products
All Coolant Thermostat Housing products of this category share the following core attributes, and JIATIAN has optimized these attributes through its advanced production technology:
Functional attribute: It serves as both the mounting carrier of the thermostat and the flow channel of the coolant, realizing dual functions of component fixing and flow guidance;
Performance attribute: It has high pressure resistance, high temperature resistance and corrosion resistance, which can adapt to the harsh working environment of the engine compartment;
Matching attribute: The dimensions and connectors fully comply with OE specifications, ensuring seamless matching with the vehicle's original cooling system and reducing installation difficulty.

4. Application Cases of JIATIAN Coolant Thermostat Housing
JIATIAN's Coolant Thermostat Housing products have been applied to multiple vehicle models due to their stable performance, and typical cases include:
Passenger vehicle field: It has been matched with a domestic independent brand's compact SUV series. The product has passed the 50,000km road test of the vehicle, and the cooling system has no leakage or abnormal temperature control, ensuring the vehicle's stable operation in high-temperature areas such as southern China;
Commercial vehicle field: ?In the high-load operation scenario of long-distance transportation, the Coolant Thermostat Housing has maintained good sealing and flow guidance performance, reducing the failure rate of the vehicle's cooling system by 18% compared with the original configuration.

5. Maintenance Guidance for Coolant Thermostat Housing
Proper maintenance can extend the service life of the Coolant Thermostat Housing. JIATIAN recommends the following maintenance standards based on industry experience and product characteristics:
Daily inspection: Every 5,000km, check whether there is coolant leakage around the Coolant Thermostat Housing (focus on the gasket/seal position), and confirm that the connection between the housing and the engine block/cylinder head is free of loose bolts;
Regular replacement of sealing parts: The gasket or seal of the Coolant Thermostat Housing should be replaced every 40,000km or 3 years (whichever comes first) to avoid aging and leakage;
Fault handling: If the engine has abnormal temperature (too high or too low), after eliminating the thermostat failure, check whether the Coolant Thermostat Housing has cracks or deformation. JIATIAN provides matching replacement parts and technical guidance for its products, and users can contact the after-sales team for support.

6. FAQ about Coolant Thermostat Housing

Q1: Can JIATIAN's Coolant Thermostat Housing be applied to non-OE models?
A: JIATIAN's Coolant Thermostat Housing is produced in strict accordance with OE specifications, and the product is matched with specific vehicle models. For non-OE models, the R&D team can provide customized solutions based on the vehicle's cooling system parameters, relying on the company's 8 large-scale machining centers and flexible production capacity.

Q2: What is the service life of JIATIAN's Coolant Thermostat Housing under normal use?
A: Based on the test data of JIATIAN's comprehensive laboratory and vehicle application feedback, the service life of the product can reach 80,000km or 6 years under normal use conditions (compliant with vehicle maintenance specifications).

Q3: How to confirm that the Coolant Thermostat Housing is the cause of the cooling system failure?
A: First, check whether there is obvious leakage or structural damage to the housing; then, through the temperature detection of the cooling system, if the small cycle and large cycle switch abnormally after replacing the thermostat, it can be judged that the flow channel of the Coolant Thermostat Housing is blocked or deformed. JIATIAN's laboratory can provide professional failure detection services for customers.
