How are Hybrid Inverter Cooling Systems diagnosed?
If any of the mentioned symptoms are noted, the cooling system will be checked for leaks, and, if any are found, not only will the leak be repaired, but the system will be flushed and refilled. However, if no leaks are found and the coolant level is correct, the system may be flushed as a diagnostic step. Finally, no diagnosis is normally needed to flush the system because it is a factory scheduled maintenance item. The only symptom necessary is mileage.
How is the Hybrid Inverter Cooling System serviced?
Flushing the hybrid inverter cooling system is much the same as flushing the engine cooling system, except there are fewer components to deal with, and the components are typically more accessible. Chemicals are introduced into the hybrid inverter cooling system through the fill port, and the system is ran. Afterwards, the system is drained, purged of old coolant, and the drain plug is replaced. Finally, the system is filled and purged of air.
RepairPal Recommendations for Hybrid Inverter Cooling System issues
RepairPal always recommends following the factory scheduled maintenance plan when servicing a vehicle. If the service mileage or time has elapsed without the service being performed, have it done next time the vehicle is in for service, or make a specific appointment. completing all services on time will reduce the likelihood of inverter cooling system failure and hybrid inverter overheating.
What to look out for when dealing with Hybrid Inverter Coolant System issues
Not all hybrid vehicles require cooling systems for the hybrid inverter. Some do not become hot enough to need cooling, and others are cooled by fans only. It is important to understand which system your vehicle uses to prevent fraudulent services from being performed or billed.
Can I Flush and Refill the Hybrid Inverter Cooling System?
This is something the average DIY can accomplish, but only if the system is completely understood. It is not identical to an engine cooling system, but the flush, drain, and refill procedures are very closely related. If the proper instructions are available in the service manual, the proper coolant and flushing chemicals are on hand, and the used coolant can be recycled, this can be done by the DIY mechanic.
