Driving and triangle lit up with check engine: Drove Fine: Is this invertor coolant pump?

It's been over 90 degrees. Triangle lit up with check engine and I know the invertor coolant pump is a common failure, so hoping that is the culprit.

How do I know for sure? I could take to O'Reillys and scan it to see if I get related codes...but don't want to drive until fixed.

On my previous gen 1 prius the pump failed and it drove poorly...lacked power (from what I remember)...Maybe even cut off once or twice...

This prius described in this thread drove perfectly normal but it just happened a half mile ago! Please advise!

 

Well, thanks to the forum, I found my old post from 3 years ago!!! Interestingly enough, last time it happened it was also July when it gets very hot....And same dash lights....Only difference is I did not scan the code yet but pretty sure it is invertor coolant pump....Here is screenshot of old thread:

 

Next question: Here is a how-to video (looks like you have to partly remove front bumper):

Is it necessary to remove bumper? How long if everything goes smoothly...Please say 2.5 hours or less!

 

I'll drive it to O'Reilleys but I'm about 100% positive it's the pump. Exact same look (screen, triangle, CEL) as my old prius that I posted a thread about 3 years ago. Was actually getting ready to order the part online but I suppose I'll scan the code first.

 

Well, that was a wasted trip, if it's over 90 degrees and you get those 3 things simultaneously (CEL top right, red triangle top left, dash screen saying warning) it is the pump.

Code was P3130 Inverter Cooling System Malfunction.

 

I just didn't want to damage hybrid battery or motor driving it....seemed risky.

Shop down the street charges $185 labor but I was thinking of having my cousin do it (he'll probably charge $100 or slightly more if it becomes a nightmare)...You think he can knock out the job in under 3 hours? Shop said 2.5 hours. Also, do I need to buy coolant?

 

Couple questions on this job...installed pump but check engine /red triangle still there, how do i reset? Reservoir has turbulance now so i believe it did the trick.

Number 2, we lost maybe 1 ounce of fluid, barely anything...we did not bleed the system...is it necessary and would i notice if air was in system? Sounds normal to me....
