This OEM-style extra powertrain coolant pump is used in specific Model X thermal management configurations to supplement coolant flow through the drive-unit and inverter loops. It is a direct plug-and-play replacement for Tesla part number 1037328-00-G, restoring correct circulation and helping prevent temperature-related power limits on the Model X.
The 1037328-00-G extra powertrain coolant pump is a compact brushless 12 V electric pump dedicated to supplemental flow in the Model X powertrain cooling system. Certain configurations use this unit to back up the primary powertrain pump, improving temperature control of the drive unit and inverter during heavy use, steep grades, or trailer towing. As the pump ages, you may notice more frequent cooling alerts, fan noise, or derated power well before any obvious leakage is visible.
| Part Number | 1037328-00-G (extra powertrain coolant pump, Model X only) |
| Application | Auxiliary / extra powertrain coolant pump used in the Model X drive-unit / inverter cooling circuit to supplement the primary powertrain pump. |
| Compatible Vehicles | Tesla Model X vehicles equipped with coolant pump 1037328-00-G. Confirm by part number on the existing pump or VIN before ordering. |
| Electrical | 12 V brushless EV-grade pump, PWM-controlled by the vehicle; plug-and-play with the OEM Model X harness (no splicing required). |
| Installation | Bolt-in replacement in the Model X powertrain cooling circuit; requires proper coolant handling, vacuum fill / bleed, and leak verification. |
Gruber Motor Company can supply the pump by itself or as part of a comprehensive Model X powertrain cooling service. If you are unsure whether your vehicle uses part 1037328-00-G, contact us with your VIN and we can confirm Model X–specific fitment before you order.
When replacing an auxiliary powertrain pump on a Model X, inspect quick-connects, hoses, and wiring for heat damage from the underbody and front subframe area. Use Tesla-spec coolant and a proper vacuum-fill procedure to eliminate air pockets that can starve either the primary or extra pump.
Our Tesla specialists can help you distinguish between the primary and extra powertrain pumps on your Model X and confirm which one you need. Call 623.433.8500 or email our service team with photos of your existing pump and coolant plumbing.
