Used about 10 oz of coolant a week for about the last 2-3 weeks.
Just last week I started getting P300, 301, 302, and I think 304, but not until then. Of course I've had some hard starts- but minor. No over heating (I have a scanner app I use every time)
What is this? Normally I thought you would see a "steam-cleaned"...

Then I got a bunch of errors afterwards. The brakes were pumped.

What brake fluid is recommended for a 2017 toyota prius prime? Also what do you recommend?

Exciting news! I’ve not only discovered another Toyota model that shares connectors to the back of the MFD/Radio with the Gen 2 Prius, but I also found a company that manufactures these Tesla style screens. I'm currently collaborating with them to make sure that these radios can showcase the diagnostics menu. Even better, since they already have access to the CAN bus from behind the radio, I’m...

I wrote “Fraud Return to Sender” and “Address on back.” I dropped off at my local post office. I’m fighting back by complaining to the post office.

If (when) I get another, I will escalate too. I suspect it is a conspiracy to filter voters and challenge any who don’t follow their toxic views.

As @Paul Gregory mentioned in another thread, there is a fair amount of ground clearance, at least compared to my MINI.

I just put a hockey puck in the cradle of my old 3.5 ton floor jack, pushed it under the front tire change jack point, and pumped away.

It had to go a little high to get both wheels off the ground, which I usually did with my...

I disassembled the rear passengers section for battery replacement etc.

Weeks later I cant recall where this white duct attaches. Anyone out there know and have a picture or diagram?

During this time my 2007's pump emits an unstable squealing sound that reminds me of the "ah-ooo-gah" horn sound on an old car. This sound is not unique. At times I have heard it from other Gen 2 Prii.

Is this sound indicative of a pump with worn bearings? I wonder if this is the time to replace it?

I don't know the car's history re the age of the pump.]]> 12 Tue, 10 Mar 2026 19:03:58 +0000 https://priuschat.com/threads/transmission-leak.259284/ https://priuschat.com/threads/transmission-leak.259284/ invalid@example.com (ronlewis) ronlewis 2 Tue, 10 Mar 2026 18:42:43 +0000 https://priuschat.com/threads/right-amount-of-coolant.259286/ https://priuschat.com/threads/right-amount-of-coolant.259286/ invalid@example.com (priusrust) priusrust Parts guy looked it up and said 13 quarts ......

Then looked up cooling system in my owners manual, and it tells me for capacity: 6.2 quarts (gasoline engine) and 1.5 quarts (power control unit).

I'm confused.....I want to drain coolant and fill up with new coolant. Simple.
I asked them about discrepancy and they and they honestly were mystified....not slightly off...it's double!
Help appreciated, thanks!]]> 2
