Auxiliary Coolant Pump fit for Model 3 & Model Y – Electric Cooling Water Pump– & Drive Unit Thermal Management

Fit for Restore Your Cooling System PerformanceThe auxiliary coolant pump is a critical component of your Model 3 or Model Y thermal management system. This brushless 12V pump proper circulation of coolant to regulate the temperature of your pack, drive unit, inverter.Why This Pump Is a Critical Cooling Componentthermal management system does far more than the cabin comfortable. It regulates temperature, manages motor heat, conditions cells before, and drivetrain components from thermal stress . The auxiliary coolant pump is the heart of the low-temperature loop, circulating coolant through, drive unit, chiller, and heat pump circuits .Why These Pumps Failcoolant pumps are compact brushless 12V units that run continuously under thermal load. Common failure causes include:Coolant leaks or air in the system – Small leaks at hoses, O-rings, or the manifold let the pump run low on coolant until it overheats and seizes Improper refill / no vacuum fill – If the system is filled without a vacuum tool, trapped can cause cavitation, noise, and early pump failure thermal load – Repeated Supercharging, hot-climate driving, towing, or track use loads the thermal system and exposes marginal pumps Age and contaminated coolant – Old or contaminated coolant accelerates internal wear, increases drag on the impeller, and can cause electrical faults Signs Your Coolant Pump Is FailingWatch for these signs:🔴 Thermal system warning messages on your touchscreen 🔴 Reduced vehicle performance or power limiting 🔴 Poor cabin heating or weak defrost performance 🔴 Coolant circulation faults🔴 Unusual humming, whining, or clicking noise from front compartment Why Choose This Spec Replacement✅ Thermal – Restores proper coolant flow through the low-temperature loop (drive unit, chiller, and heat pump circuits). Stable temps during Supercharging help maintain speeds and long-term pack health ✅ Cabin Comfort Restoration – On heat-pump Model Y/3, the coolant loop integrates with. A pump restores strong heat and defrost performance ✅ Plug-and-Play Design – correct mounting alignment. No coding or modification required Package Includes1x Auxiliary Coolant Pump Quick reference guide⚠️ NOT INCLUDED: Coolant, O-rings (sold separately), mounting hardware, or vacuum refill equipment.CompatibilityModel YearsModel 3 2017, 2018, 2019, 2020, 2021, 2022, 2023 Model Y 2020, 2021, 2022, 2023, 2024, 2025 Professional-Grade Replacement – Important Installation NotesWhile DIY-capable owners with thermal system experience can perform this replacement, proper procedure is critical:Put car into Service Mode – Access via touchscreen controlsSafely disconnect low power Drain coolant – Approximately 2-3 liters of G-48 blue coolant3 bolts (10mm socket) – torque to 5 Nm on reinstalllightly lubricated O-rings on the manifold ports – lubricate with clean coolant to aviod tearing Install pump and reconnect electrical connectorRefill with spec coolant – use vacuum fill tool to aviod pocketsRun full Coolant Fill/Drain routine in Service Mode Do not drive immediately after installation without performing the coolant bleed procedure. pockets can cause cavitation and immediate pump failure. Vacuum refill is strongly recommended Professional installation strongly recommended for owners unfamiliar with Service Mode and thermal system bleeding procedures .Why Replace Your Coolant Pump ProactivelyA properly functioning coolant pump:Maintain ideal temperature during Superchargingthe drive unit and power electronicsEnsure proper HVAC and cabin heating performanceAviod costly thermal system faults and damageMaintenance Tip: Any time you replace a coolant pump on Model 3/Y, install, lightly lubricated O-rings on the manifold ports and run the full Coolant Fill/Drain routine in Service Mode. Simply topping off the reservoir can leave air pockets that cause noise, poor therm

• Fit for ✅ Critical for & Drive Unit Cooling – This brushless 12V electric pump circulates coolant through your pack, drive unit, inverter, and HVAC system. Proper flow aviod thermal derating and preserves Supercharging speeds .
• 🚨 Fixes Common Cooling Issues – Direct replacement for pumps that fail, causing thermal system, reduced power, poor cabin heating, unusual front compartment noise, or coolant circulation faults .
• 🌡️ Aviod Performance Derating – Maintains ideal temperature during DC fast. A failing pump triggers thermal limits and power reduction – replace proactively to your.
• ⚙️ Professional Installation Recommended – Requires coolant drain/refill with G-48 blue coolant, Service Mode bleed procedure, and lubricated O-rings. Includes pump only – O-rings sold separately .
