What is the difference between inverter coolant and engine coolant?
Inverter coolant cools the device that turns DC power (batteries) into the AC power that runs the electric motor. Has nothing to do with engine coolant.
How do you check antifreeze in a Prius?
You can get a quick check of the level by looking at the markings on the side of the reservoir. Should the liquid hit the “full” marking line, you’re all set. If it falls short of that, remove the radiator cap and add in the coolant or a 50/50 mix of coolant/water.
What kind of cooling system does a hybrid have?
Most hybrids have a separate cooling system for the inverter and electric motors/generators in the transmission case. These cooling systems typically have their own electric pump, heat exchanger and special coolant. On the Fusion, Escape and Prius, there are two coolant reservoirs under the hood. Always make sure the fluid is at the correct level.
Is the coolant in the inverter the same as the engine?
Yes, it’s the same coolant in both the engine and the inverter. Considering this, what is an inverter coolant? Inverter Coolant Pumps.
What kind of inverter coolant do I need for my Prius?
It is also backward-compatible and has a longer specified change interval (50 k miles vs 30 k miles) so one might consider using the new stuff instead, at the next change. No other coolants are known to be acceptable for use in Prius, so your only choices are LLC or SLLC.
Can you drain the coolant from the inverter loop?
You can easily do the ICE coolant loop drain and refill yourself, but the Inverter loop coolant is difficult to refresh as it tends to retain air bubbles. If you don’t get the air bubbles out, you may overheat the inverter ($$$). As was said, stick with Toyota coolant (preferably SLLC). I had the dealer do the job. Ditto on Jeff’s remarks.
How does the hybrid inverter cooling system work?
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.
What kind of coolant does a hybrid car use?
These cooling systems typically have their own electric pump, heat exchanger and special coolant. On the Fusion, Escape and Prius, there are two coolant reservoirs under the hood. Always make sure the fluid is at the correct level.
Yes, it’s the same coolant in both the engine and the inverter. Considering this, what is an inverter coolant? Inverter Coolant Pumps.
How often should a hybrid inverter be flushed?
It is not wise to have services performed after the service interval has elapsed. How often should the Hybrid Inverter Cooling System be flushed? All hybrid vehicles should have the hybrid drive DC to AC inverter cooling system flushed, drained and filled at least once in their useful service life.
