Coolant Pump (50W, LT, Service) for Tesla Model S (2012-2016) | 1057257-01-G

Why This Coolant Pump Is Non-Negotiable for Your 2012-2016 Model S

What It Actually Does (No Tech Jargon)

• Battery Temperature Guardian: Circulates coolants to pull heat from the battery pack, preventing overheating during fast charging, highway drives, or hot weather. No more “Battery Temperature High” warnings that slow charging.
• Protects Power Electronics: Keeps the inverter, motor, and charger cool—components that generate massive heat during acceleration. A cool power system means smoother performance and no unexpected power dips.
• 50W Efficient Operation: Tuned for Tesla’s 2012-2016 Model S electrical system, it delivers enough power to circulate coolant effectively without draining the battery unnecessarily.
• Quiet, Reliable Flow: Built with precision bearings to run quietly (no loud humming from the engine bay) and maintain consistent coolant pressure—critical for steady temperature control.

Signs Yours Needs Replacement

• Battery Overheating Warnings: Your touchscreen shows “Battery Too Hot” or charging slows dramatically (even at a Supercharger).
• Reduced Range: You’re losing 10+ miles of range compared to usual—overheated batteries can’t hold a full charge.
• Loud Humming from the Front: A grinding or high-pitched noise from the engine bay (the pump’s bearings are worn out).
• Coolant Leaks: Puddles of bright green/blue coolant under your Model S (a cracked pump housing or failed seal).
• Power Shutdowns: Your Model S limits acceleration or shuts down temporarily to protect overheated components.

Built to Tesla’s Factory Standards

Why It’s Better Than Aftermarket Pumps

• Tesla-Exact Electrical Match: Built to work with your vehicle’s 12V system and cooling controller. No “Coolant Pump Fault” error codes on your touchscreen (a common issue with generic pumps).
• Perfect Fit, No Mods: Uses the same mounting points and coolant hose connections as the original. Installs in 1–2 hours with basic tools—no drilling or rewiring.
• Tested for Durability: Runs 500+ hours of simulated driving (including hot/cold cycles) to ensure it lasts 50,000+ miles—same as Tesla’s OEM part.
• Leak-Proof Seals: High-temperature O-rings (rated to 250°F) prevent coolant leaks, unlike aftermarket pumps that fail in 6–12 months.
