Hi usnavystgc My 2008 prius has a terrible coolant reservoir leak. The coolant tank empties within seconds and everything comes out from the bottom. When I press the reservoir hard against the inverter, the leak substantially decreases. Am I right in assuming that changing the reservoir would fix this issue? However, it seems impossible to get to the back nuts of the reservoir. How do you do that without taking out inverter? Any help is highly appreciated because driving with this problem has probably caused red triangle to on on the dash board. Please Edit: OK. So, I succeeded in getting the reservoir out by undoing the cawl (?) and wiper system. It indeed had a crack in the port that goes into the inverter. While I wait for a replacement to come from ebay, I would try to use epoxy to fix the one I have and see if it holds up. Thanks VDA
