This pump is a cross-platform workhorse common to the S / 3 / X / Y Tesla Vehicles. This OEM-style auxiliary coolant pump circulates coolant through the battery, drive-unit, and radiator circuits on compatible Tesla S / 3 / X / Y vehicles. It is a direct plug-and-play replacement for part number 1619322-00-C, designed to restore proper flow, reduce temperature spikes, and keep thermal management systems performing as they should.
The 1619322-00-C auxiliary coolant pump is a compact brushless 12 V electric water pump used in Tesla’s shared liquid-cooling architecture on Model S, Model X, Model 3 and Model Y. Multiple pumps circulate glycol-based coolant through the battery pack, drive units, power electronics and chiller/heat-pump assemblies; this unit is one of the key components that keeps those loops moving. When it starts to fail you’ll typically see reduced coolant flow, higher component temperatures, more active radiator fans and occasional power derating rather than a classic “overheat” light.
| Part Number | 1619322-00-C (auxiliary coolant pump) |

Gruber Motor Company can supply the pump on its own or as part of a broader cooling system service. If you are unsure whether your vehicle uses part 1619322-00-C, contact us with your VIN and we can confirm fitment before you order.
Any time you replace a coolant pump on a Tesla, inspect hoses, quick-connects, and the coolant manifold for leaks, and use the correct Tesla-spec coolant. A proper bleed procedure helps prevent air pockets that can overheat the pump.
Our Tesla specialists can walk you through diagnosing coolant flow faults and selecting the right parts. Call 623.433.8500 or email our service team with photos of your existing pump and plumbing.
