I am getting hit by disaster after disaster but might have a solution My 2009 had it coolant pump replaced about 40K miles ago. I believe the inverter coolant pump is part of the inverter? Can I just simply swap inverters? Edit: Never mind, I found that the inverter water pump is actually just under the driver's side headlight. I think I can do the same thing however.
Replaced the pump with the one from the 2009. I checked before I changed them out and there was no fluid movement in the fluid reservoir before I replaced it and saw rippling with the replacement In my 2009, I had it changed out by Toyota, thinking it would be too hard for me to do. The whole job likely took under an hour between both cars. Definitely less than two hours. I really feel ripped off considering that they charged me something like $500. Drove the car back and forth to DAV, 15 minute trip each way and about 8 miles each way. Hope that was at least a half decent test. Is Code P00A93 95% of the time "Replace Pump?" I know if can be due to air bubble, fuse to pump, and a few other things but are they pretty rare?
20 min change leaving original pump bracket left in place. new pump on old bracket. Cooloant in air gone code should be gone.
It could also be something like leaves and dirt blocking the bottom 1/4 of the radiator. The code just indicates that the inverter got "too warm", so anything that affects the cooling SYSTEM can be a concern. Yes, most times it is the pump. I have read accounts here of some people having problems with some aftermarket pumps that would occasionally just "not pump". Then work fine next drive. Posted via the PriusChat mobile app.
If I have to buy a new pump, it will have to be an aftermarket due to current finances but currently using a used one from my wrecked car. Should be a revised model of the pump.
I've replaced my coolant pump multiple times in 10 years. there are pumps on amazon new for 25$ can't help but wonder if they are the same pumps that places like advance auto sell for 200$ my factory pump lasted to 133K (2009-2019) the Toyota OEM dealer replacement at 133K only lasted 79K and ran for 3247 hours that was replaced with a used one that got me 56k and it ran for 2057 hours. the current replacement from nov 2024 is an advance auto lifetime warranty model its run for 762 hours and 18K and as another mentioned, don't bother replacing the bracket, just remove the 3 bolts that hold the pump to the bracket. it will save you so much time
There are 12 volt low and medium flow coolant pumps available from major mfgrs smaller easier to fit w 5/8 barbs in proper orientation
I am tempted to buy an Amazon one to put on my wrecked car just for now Eventually it will be donating its engine if I can ever get a snapped bolt off. Also, I am a big believer in the concept "If you hear hoof beats, think horses, not zebras." It is a medical concept but works for other things as well. Why I often ask in these threads what the most likely issue is.
In my generation too I can drive without it in 100° weather I'm usually not on hi way running svc calls did gor a year not an issue at all
