Hybrid Inverter Coolant Pump Repair in Las Vegas
Your Toyota Prius, Camry Hybrid, Highlander Hybrid, or Lexus hybrid model relies on a dedicated electric inverter coolant pump to keep the power control unit (inverter) from overheating. Unlike your engine's main cooling system, this small electric pump circulates coolant exclusively through the inverter assembly, protecting the sensitive IGBT power transistors that convert your battery's DC power into the AC power your electric motor needs.
Because the inverter coolant pump runs almost constantly whenever your hybrid system is active, it experiences significant wear over time. When it starts to fail, the consequences can escalate quickly — a failing pump often leads to inverter overheating, and inverter damage is one of the most expensive hybrid repairs on the market. At Prius Battery Repair LV, we specialize in catching inverter coolant pump failure early, before it turns into a much larger repair bill.
Signs Your Inverter Coolant Pump Is Failing
- Whining, grinding, or rattling noise from under the hood
- "Check Hybrid System" warning light
- Diagnostic trouble code P0A93 (Inverter Coolant Pump Performance)
- Sudden loss of hybrid power or limited "turtle mode" power
- Inverter running noticeably hotter than normal
- Coolant reservoir level dropping without a visible external leak
- Hybrid system shutting down unexpectedly after extended driving
Why a Failing Coolant Pump Puts Your Inverter at Risk
The inverter coolant pump exists for one reason: to keep your inverter’s internal components within a safe operating temperature. When the pump slows down or stops circulating coolant, heat builds up rapidly inside the inverter housing. Left unaddressed, this heat can permanently damage the IGBT transistors and capacitors inside the inverter — turning a relatively affordable pump replacement into a far more expensive inverter rebuild or replacement. Catching pump failure early is the single best way to protect your hybrid investment.

Frequently Asked Questions. Ask us
It circulates coolant specifically through your hybrid inverter (power control unit), keeping its internal electronics at a safe operating temperature.
We strongly recommend against it. Continuing to drive with a failing pump significantly increases the risk of permanent, expensive inverter damage.
Most replacements are completed within a few hours, often the same day.
No. Your hybrid has a separate electric coolant pump dedicated solely to the inverter, distinct from the engine's cooling system.
Yes, every inverter coolant pump replacement is backed by our exclusive hybrid repair warranty.
