The ULTIMATE 4Runner Coolant DRAIN and FILL 

Great job. Just a note. Regardless of how well you burp it while idling, the system will continue to burp small amounts of air over the next few hundred miles. That will impact the overflow tank level. Don’t panic, it will eventually get all air out and the tank level will stop lowering.

That res makes life so much easier

Just did my driveshaft and rear differential luckily my 4R is 2wd so i only had my rear diff and only 2 grease points on my drive shaft so now ima do the coolant flush this weekend and your videos are definitely my go to on how to videos

Thank you for creating this channel and providing clear and fantastic videos! You and The Care Care Nut are my go-to for anything 4runner/Toyota/Lexus!

Awesome! Thank you for providing such high quality content. The 4R community is just amazing. God Bless you all!

Followed this video on my 4Runner and Yaris with 0 issues. You've got the clearest instructions out of all DIY videos I've watched. Thank you!

Thanks for doing these videos. I love the list of tools and parts before you run us through the job.

Found your channel a couple weeks ago and have started purchasing everything i need for the 100k maintenance on my 2015. Thank you so much for this. Your videos are high quality, very informative, and have fantastic execution!

Thanks for the video….just did this yesterday. Easy job but your video was very helpful.

Good job man.. you rock.. I do all the work on the 4Runner myself too... please be always extra safe and always use double jack stands for backup.. and put tires under the car if lifted...

I just decided to drain fill every 30k when I do my tranny and diffs as well as brake fluid. Cheaper than water pumps and head gaskets. I diy so it’s convenient for me to just do it myself

The best video that I have seen on doing this job....Thank you

Another banger, thanks for making. I think you've pretty much done videos on all routine maintenance at this point. We're going to have to start requesting more obscure tasks. 😂

5/16 ID tubing fits the block drain perfectly, FYI.

Good job. Nice vid. Make sure not to back off the drain valve too much on the radiator or it will drain down the tube as well as all over the skid plate. Thanks 👍

So your hose sizing did not fit on the engine drain. Might I recommend people use the radiator pickup hose from the radiator reservoir to connect to the drain ports. Then you also don’t have to purchase the tubing and it doesn’t make a mess of coolant on the engine block. Otherwise great video thanks for posting.

Thanks! Never knew about the block drain.

I’m pushing 40,000 on my 2016 5th gen gonna go ahead and do this for some preventative maintenance hopefully the water pump will last longer..🤙🏽

Thank you! Heading out today to get fluid to do the flush. ALways great content and I appreciate your time and effort.

Great video with clear instructions. Thanks

Excellent video, clear, concise, to the point. I had kind of forgotten about this, I'm gearing up to change all my other fluids, I'll add this to the list.

Your video instructions are simple, on point and effective. Thank you and I subscribed and follow you on IG as well.

Great video. Very easy to follow

Great videos, keep them coming!

I just drain the radiator, refill as you did, drive for a few days and repeat. I don't do the engine block. I mean, with your method you're getting 8 out of 11qts (so even with the engine block drain it's not a full drain) and with my method I pretty much get the same. Sure, mine may keep a bit more of the 'pre-changed' coolant, but it's really easy/quick to do and I've done it every 50k (first at 50k and just repeated as I turned 100k). Either way is more than enough, I'm sure! Thanks for the video.

Thank you for the video it was high quality it’s video and audio and your skill to talk us through the process is excellent. I will ask you to check out “The Car Care Nut” video on Toyota Cooling replacement to see how he truly bleeds out the entire cooling system, to really remove air pockets from the system.

Very well done on this video!

Thanks man, great video and info

Thank you so much for making this video....unfortunately for me I don't have a place to lift my 4runner limited and change it's coolant.i gotta pay someone to do it instead.otherwise just a few questions. 1.can the old coolant fluid be flushed out using a vinyl tube instead of removing the platic jug that's inside the engine bay instead of removing it completely to empty out ? 2.i have a 2014 4runner Limited almost approaching 100,000 miles,would there be an additional drainage on the front passenger side engine block ? I'm definitely gonna stand and watch the mechanic to make sure he's doing exactly what you have done.again thank you so much,I really appreciate these maintenance videos.😊

Thanks a lot for the very good video. It will help me a lot. I read some things about draining the thermostat too. What about it? Why did you not include it in the video. Is it necessary? Thank you

Another great video! I know oil changes are easy and I don't think you have ever done a video on one, but my question would be what your thoughts are on engine oil additives like Ceratec Liquimoly for 4Runners?🤔

Thanks

Very nice.. doing that

Awesome job on the step by step video. This will help me tremendously and gave me the courage to try this for myself. Thank you for all the great information and as others have said listing what is needed. Please keep the videos coming ! Quick question on changing the coolant. When graining the blook do I turn the heat knob to the heat position ? Thank you in advance for your reply! Also how difficult is it going to be to burp all the air out of the system and in all tips will be very helpful. Again thank you so much!

i know its very basic, can you do a tire rotation indicating all the jack points dont want to mess the part/body that is not the jack points. Thanks.

3UG V8s(last one) are popping head gaskets from people skipping coolant bc acidity goes up and it eats away the head gasket between cylinders... gonna do my 5G soon she just crosswd 105k

Thank you

Have you ever used a compresssor to pull a vacuum on the cooling system (to check for leaks) and then filled it using the vacuum to eliminate trapped air?

Great video. Is it a good idea to change the hoses at 100k as well?

@T4Rgarage Very nicely done video. I think you did a great job explaining the procedure and detailing each tool that was used. Two questions though - can an ordinary funnel be used or is there something in the bleeding that makes the funnel in the video better? Is more bleeding required if the funnel with the seal is not used?

Two things-The blue cap with the blue nozzle from the funnel kit shown here fit tighter on my 2018 the green one in the video was very loose and leaked when filling the funnel. The recommended tubing is definitely too big for the engine block drain it drips and runs everywhere. 1/4 is too small so what’s the secret to keep this thing from dripping all over the place?

if you leave the radiator cap on during the initial drain you will drain most of the reservoir.

looks like you have some significant oil leaks... unless that is some sort of undercoating?

Is it necessary to drain from the engine block? What if you just drain from the radiator?

Awful lot of oily residues down there at the bottom?

Great video as always.. I have 2016 4runner Sr5.. and manual states 11.1 qt so I need 3 Gal? Thank you

If you don’t wanna deal with draining the block just drain and fill the radiator 2 or 3 times over the course of a week while running heat to flush/mix out all old fluid

Will this video apply to the 2015 4Runner limited v6 ? Also I have 65k miles should I go ahead and change the coolant let me know you guys thoughts thank youuu👊🏼

Hello. I am about to do this process on my 4Runner. When refilling do you wait for the thermostat to open and then add more fluid.

Will this process work for a 4th gen too? Specifically, just draining the coolant from the engine block. Is there a drain on the block for 4th gens?

In your video you show 55-45 pre-diluted coolant. On the Amazon link the coolant shown is 50-50. Which one is the correct one?

Is that rust prevention all over the place or leaks?

Did you fluid film underneath?

So... the bolt under the passenger side snapped off. Apparently it was on super tight and rusted. So, its broken off. (5:14) Tomorrow Ill attempt to use a bolt extractor to get it out. Do you know if that bolt fully unscrews?

Why is there so much oil under your 4-runner?

Probably should add what to do with the used coolant.
