Coolant Heat Storage Container price/maintenance

If the Gen 4 Plug-in Prius includes an electric heater in the coolant tank, to warm it up, along with the interior when it's plugged in, that might be the deal-maker that makes me trade in my 2012.

 

great answer.

 

Please explain the "system" to us.
How does it work ?
What is it supposed to do ??

Heating the coolant in the overflow bottle would do little or nothing because that liquid does not usually circulate through the engine.

 

Yeah, that part is replaceable and you can DIY. Looks like it is sold as a set w/ some other parts. $821.56 at Camelback Toyota.
You can try Steve at Autobeyours, to see if he has any inverter coolant heat storage tanks for sale.

Dealer labor/greed rates vary all across the country and w/in the same city (if multiple dealers exist). If you live in a more urban area or close to one, many service departments are open on Sundays, so start calling to know definitively.

In Long Beach, there are two Toyota dealers. One wanted $800 in labor for front strut and rear shock replacement. Another wanted $1035.​

Did something hit the coolant canister, thus the need for replacement?

EDIT:
Maintenance for this item (coolant canister) is part of the engine cooling loop coolant replacement. At 100K, drain the coolant from the canister and radiator as these two items are connected.. Then this needs to be done every 50K miles. It is a simple drain/fill procedure. But careful bleeding is required otherwise problems will arise. Maybe this is what you are talking about?

There is also the inverter cooling loop that cools the inverter and transaxle (think transmission). This cooling loop has the same 100K mile, then every 50K mile, drain/fill maintenance. But careful bleeding is required, otherwise problems will arise.
