UK / Europe Prius 2 Coolant Change

Was the radiator full to start with?

I got 3.8 litres out when I did mine. Never figured out why it was so little. I eventually got 3.8 L back in but initially only got 2.8 L in.

 

Not sure. I did the same, I drained the majority from the radiator before opening the engine block drain. Very little came out the engine block.

 

As long as the radiator cap is off, it shouldn't make any difference.

 

Worth noting: you’ll never get the specd volume, some will always hang up in knooks and crannies.

but you shouldn’t be getting significantly less than what others are getting, following the same procedure.

 

Some coolant always remains in the compartments and pipes.

To drain as much coolant as possible from the engine systems, I raise the rear of the car while tilting the front of the car down.




To fill the engine system with coolant as much as possible, I raise the front of the car by driving onto a hill. Or two hills))
