Prius engine coolant change: Part 1, drain and refill

This video is the first part of a two part video showing one of the ways to change the engine coolant in a 2006 Toyota Prius. I'm pretty sure the same process will work on the 2004-2009 model years. Part 1 of the video covers draining and refilling. Part 2 covers bleeding the air out of the system.

Even if I didn't need advice to change my coolant, it's awesome seeing a dad being a dad. This is the good stuff. Thanks for sharing the information and entertainment of heart:)

Thanks for your videos. Helped me change my inverter and engine coolant. Like you I replaced 1.5gal in my engine coolant (took a while to drain, but wasn't too bad). My inverter coolant was around 0.5gal (or a little short). Here are the tricks that I found (no bleeder hoses needed). Just pour the coolant in, and when it is hard for it to naturally flow, just squeeze your tubes. Then when that is "full" and can't be burped, use the motor to run the fluid through the system. Whether that is the one for the engine coolant (and the relay short) or turning the inverter on by pushing the power button twice. It only take a few seconds maybe twice of doing and doesn't kill your 12v much. Then pour and burp the hose. Still make sure to open the bleeder tubes, but not like you have to drain a whole bunch. And after a day of driving, I will likely top off my inverter coolant. After doing this and taking 3 hours, I would say it could be done in an hour, and only consuming 2 gallons of the Toyota SLLC2 50/50 coolant. Hope this helps!

Thank you for showing the location. So many people dont show the location

[@kvjackal7980]

Thank you so much. Really appreciate the vid. Tell your son thanks for filming, it helped me out a lot. 🙂

[@mark52111]

Excellent video! Thank you for posting. Your input made this job much much easier. Not including research and parts procurement time, I was able to complete the job in 2 hours. Jacking up the passenger side seemed to help a lot with draining and filling. Drain time was about 30 minutes for me. Refill was a breeze using the "hot wired" coolant tank pump and bleed valve. I ran the pump roughly a half dozen times. I drained 1.5 gallons as shown in video. Only mistake I made was not reconnecting coolant tank heat sensor before startup which threw a code on startup. I cleared the code w no problems using my minivtech and laptop. Also, as I posted earlier, the bleed hose should be smaller than 1/4" inside diameter. I made an adapter to get the 1/4" tubing to work. Also, I only needed to remove 3 "wood" screws and one plastic clip to gain access to bottom of canister/drain valve and sensor. Jack that side of car up to do this, makes it much easier.

[@AnthonyGalations329]

My check engine light came on. Is there a way to turn off the light without a minivtech laptop?

[@scottjames9739]

Just wanted to add my thanks. This is definitely the most helpful video on this process out there. Saved about 400$ doing the engine and inverter coolant with your help. Freaked out a little when the engine light came on, but then I remembered I hadn’t reconnected the electric plug under the coolant drain. Did a battery disconnect to clear the code and a ok after that.

[@AnthonyGalations329]

Scott James is ur battery in the truck of the car ? Is there a video on how to do that ? I can’t turn of my check engine light off.

[@bishopforme]

Very informative, just bought an 08 P2 with 150K miles. Will be doing this & ATF changed soin

[@ypaut]

Hello, thanks a lot for the video! Little tip I read somewhere is to plug a tube from the bleeder valve to the overflow tank so that you can see when it starts leaking coolant, without spilling it EDIT: well that's exactly what you did right after actually

[@jerrelbailey1714]

Jason, you do sound like a Goober, but that's how most instructional video narrators sound like. Lol. I just bought two 2007 Priuses and your video has set me on a path to maintaining my cars at a low cost. I'd like to send you a gift. I'll private message your channel to make arrangements. I'm placing this message in the comments to get other viewers that have benefitted to do the same. I'll also send you some suggestions, as problems come up. Maybe I could sponsor some future videos. Thanks.

[@Typhoonbladefist]

Thanks, for these two videos, it really helped me change my coolant after a dealer repair fuck up. Not only did they use the wrong coolant, they didn't even bleed it. I drained a little over a gallon and that was after I had put in half a gallon of water when I suddenly found it overheating on the road.

[@onefixitman]

Only 90k views. This video is awesome. You did a great job.

[@megajlaing]

That plug at 6:20 I unscrewed the bolt you see at the base and twisted my wires up, now the temperature guage doesn't register. Loved your video though! I watched several tutorials of this process just to cross examine how different set-ups might look compared to mine. However, when it came time to the job I drew a blank on that step. The plug would not come undone even with a crecent wrench. So I moved to default, UNBOLT. I later noticed my fans didn't kick on and quickly noticed my botch-job on the wires from twisting out that plug.

Thank you and great job at being a Dad.

In A great video, Would be nice to see complete video of work done.

[@recentmuslim01]

[@jorgediaz-kb3dd]

Thanks. It's a great video.

[@kumara5492]

Nice Video. I wanted to do this for my Prius V 2013 , but not sure where the drain plug is located Can someone please confirm how to get to the engine coolant drain plug on Toyota Prius V 2013. Thank you. I subscribed

[@keithandrew3079]

thanks for sharing this video, wee have a 2002 gen 1 prius, left hand drive here in New Zealand, but most of the info was great for us, but could not find bleed valve on this model? any other info would be appreciated, maybe we will have to burp ours by squeezing the hoses ect,

[@fluxquantum1404]

@reedjasond Thanks so much for putting this together. I was wondering, if I'm just trying to top off the coolant, do I need to worry about bleeding air from the line?

[@ginakim4706]

should I drain the reservoir coolant fluid first? can't I just refill the new coolant fluid over the old one in the inverter coolant tank?

[@AdrienneShianne]

I felt like I was here lol thank you !

[@James-mw4sh]

How hard is it to flush the system before refilling?

[@Sammie_E_Tellem]

Is the car on while refilling?

[@farmerinchico]

Very helpful. Thanks for posting this video!

[@peng28]

thanks you so much

[@richarddavis5603]

is there a difference in how this is done on a 2010 prius there is no radiator cap. Is there also a bleeder on the 2010 like the one in videp

[@victorrader4349]

FYI, there are 3 drain locations: Radiator, the one shown, and one at the back of the engine. kzbin.info/www/bejne/ZoeZgaqOjdhqfrM

[@recentmuslim01]

very grateful for your video

[@amealnet2495]

Car ramps might make it more accessible.

[@donutworry]

Where can I buy his favorite tool at time 2:15 - the socket wrench that swivels into ratcheting screwdriver-type wrench? Anybody know?

[@mackuss]

Wait so, engine coolant and inverter coolant aren't the same thing? Isn't that what the 3 way coolant control valve does? It's the hub point between both halves of the engine? It's an entire system isn't it?

[@RyanJordanrwj]

two different systems. I'd recommend checking out Lucious Garage on youtube.

[@Kay-dx8vm]

Thanks for making this video. So we use this coolant for both engine and inverter?

[@cdgregOG]

Yes, both the ICE and inverter use the pink Toyota sllc.

[@modified93tc]

Thank you for this video my friend....

[@renmedia]

It`s an old video, but he mixed up engine coolant with hybrid coolant big time.

[@PakReviewMachine]

Very Well done.

[@gp1003]

you forgot to flush the radiator. There is a small yellow valve at the bottom of it as well.

[@squirrelgray945]

Thanks for the info.

[@blue52851]

Thank you. This is great.

[@anouarhemmouch2073]

Hey I’m looking for the bleeder I don’t have one in my car I literally checked every corner

[@robertjara2744]

I have an '04 and also have the same problem, is this model specific or should we just dump coolant everywhere?

[@MIAH700]

Great video....

[@karlinamillion]

I am changing the water pump, could I save & reuse the coolant, as it's not due a change?

[@UnitedPebbles]

It is a $80 bottle at the dealership. If it clean but you know these thing changed when it heated and then expose to air also changed the chemical?? I would not reuse it if it expose to that much air after heated?? I am just guessing based on engine oil concept.

[@Bk2fut100]

thanks!!!

[@Ddoglatin]

Like it

[@schoc13]

This is funny! :). But thanks!

[@danbeavers8387]

See comments on part 2!

[@danbeavers8387]

Dan Beavers Also, using an amp meter to power the pump is a great idea. Mine was a little over 4 amps with no air being pumped. It would be a good idea to measure the amps before draining to have a target value to compare to when you think you are done.

[@jimmyharris2006]

speak a litle louder on next , but thanks for the video

[@moeajarmah2954]

This part is not exist in my car

[@BawdSpeellar]

Make sure to taste it to make sure it's the right stuff.

[@cbnx82703]

Can you do a Brain surgery video for us as well? You can use your camera person as the subject!

[@archypop]

wow dude please learn how to use a ratchet first ....damn
