Glad to know it helped! Yes I think you are right that the MGs are in the same cooling loop. If the csv log files are not deleted yet you can also plot the history of the various temperatures during the drives.
Thanks I already did that. Last week , to determine definitively before taking out the pump, I plotted the inv1 temp from the log files going back to September 2016. I plotted the inv1 portion of the log files using Excel , The plots indicated that the pump failed sometime after Jan 31 2017 so early this week I headed over to my local Toyota store with the non-functional pump still bolted in. ( weather is cool here at the moment) ccdisce
