Coolant Pump – Powertrain – 1037327-00-G

Powertrain Coolant Pump 1 – (1037327-00-G)

This OEM-style powertrain coolant pump circulates coolant through the Model S / Model X drive-unit and inverter cooling loop. It is a direct plug-and-play replacement for Tesla part number 1037327-00-G, designed to restore proper flow, reduce temperature spikes, and keep the power electronics and drive unit operating in their ideal temperature range.

Why these pumps fail

• High under-hood temperatures and continuous duty cause bearing and seal wear over time.
• Debris or degraded coolant can erode the impeller and housing, reducing flow to the drive unit and inverter.
• Electrical stress or moisture intrusion may lead to intermittent operation or no-start conditions.
• When flow drops, the vehicle may respond with limited power, reduced acceleration, and powertrain temperature warnings.

Our solution

The 1037327-00-G powertrain coolant pump is a compact brushless 12 V electric water pump used in Model S and Model X powertrain thermal management. It provides flow to the front drive unit, gearbox housing, and inverter cooling plates. As these pumps age, you may see reduced coolant movement in the sight lines, higher drive-unit temperatures, or derated performance under sustained load, all of which are corrected by a healthy replacement pump.

• Direct replacement for Tesla part 1037327-00-G with factory-style connector and mounting bosses.
• Restores proper coolant circulation through the powertrain loop on Model S / Model X.
• Recommended whenever you have noise, leakage, stored cooling-system faults, or high-mileage components in the drive-unit cooling circuit.
