Coolant Pump fit for Model 3 & Model Y – 1Auxiliary Water Pump – Drive Unit Cooling

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 electric pump proper circulation of coolant to regulate the temperature of your pack, drive unit, inverter, and HVAC system .Why These Pumps Failcoolant pumps are compact brushless 12V units that run continuously under thermal load . Common failure causes include:Coolant leaks or in the system – Small leaks at hoses, O-rings, or the manifold let the pump run low on coolant until it overheats and seizesImproper refill / no vacuum fill – If the system is filled without a vacuum tool, trapped air can cause cavitation, noise, and early pump failurethermal load – Repeated Supercharging, hot-climate driving, towing, or track use exposes marginal pumpsAge and contaminated coolant – Accelerates internal wear and can cause electrical faultsSigns Your Coolant Pump Is FailingWatch for these signs :🔴 Thermal system 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 compartmentWhat This Replacement Pump Does✅ Restores proper coolant flow – coolant moving through, drive unit, chiller and heat pump circuits to aviod thermal derating ✅ Supports DC fast – Stable temps during Supercharging maintain speeds and long-term pack life ✅ Improves cabin comfort – On heat-pump Model Y/3, the coolant loop integrates with HVAC; a pump restores strong heat and defrost ✅ Direct replacement for 3/Y – Shared Model 3/Y pump design with electrical connector and mounting – no wiring modifications CompatibilityProfessional Installation RequiredReplacing a auxiliary coolant pump requires:Service Mode access via touchscreen Coolant drain (G-48 blue coolant) and vacuum refill Removal of front shields to access coolant manifold Full Coolant Fill/Drain routine in Service Mode to bleed air ⚠️ CRITICAL: 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 .Installation Torque SpecificationsPump mounting bolts (4x): Maintenance 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 thermal performance, or a repeat pump failure .Package Includes1x Auxiliary Coolant Pump Quick reference guide⚠️ NOT INCLUDED: Coolant, O-rings, mounting hardware, or vacuum refill equipment – sold separately.your cool and your performance strong. Replace your failing auxiliary coolant pump today and drive with confidence.Professional installation strongly recommended for owners unfamiliar with Service Mode and thermal system bleeding procedures.

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