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.
Yeah, I noticed the same thing when I changed the coolant in my Yaris. I just topped it off over the course of about a week when the fluid dipped slightly. After that, it leveled and was good to go.
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!
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
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 👍
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!
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. 😂
Maybe you can focus on the 'soft skills' of 4Runner maintenance,@@T4Rgarage - like how to convince our wives to let us install mods like the Victory 4x4 DAM on their daily drivers.
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...
Great video.. just did this on my 4Runner. I pulled out about 1 gallon from rad and 1 gallon from engine block. One thing is the 3/8 hose is little loose for the engine block drain.... But I managed.... Thanks again..
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.
Thank you for all your vids. So, I just did this on my 2010 t4r after almost a year of sitting on the product and after I finished, I just realized that red isn’t just concentrated pink. I drained the petcock valve and the block with no extra water flushing, and just refilled with 50/50 red and distilled water. Am I good? There is no definite answer online and Im worried about the residual pink that was still inside mixed with the red. Thanks again
Great video, just did this today and if you have an OE skid plate it aint that easy. You just dont remove 4 bolts. After removing those bolts the plate is hinged in the front with these funky metal tabs that were a pain to get loose and a royal pain to get back in. Next time i do this job im just going to cut the tabs off with a grinder. Not worth the hassle IMO
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!
Thank you! Yes, you should have the heat knob cranked to max. Follow the procedure to burp most of the air, little bit will work its way out on its own after. Just keep an eye on your overflow tank for 2 weeks and top up if necessary.
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
The Toyota service manual calls for the engine drain(s) and radiator drain only. I think this is why the service interval after the first change goes from every 100k to every 50k, as you don’t quite get all the fluid out. This method gets most of it out though without overcomplicating things. Hope that helps
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?🤔
Thank you! I haven’t researched additives much. I think I would stick to whatever is recommended by the manufacturer unless there was an issue. A high quality synthetic is what I use with factory Toyota branded filter
I just watched a video on additives, they ran lab tests on oil with and without the extra additives, turns out the additives actually made the oil perform worse.
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.
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?
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.😊
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?
@@michaelfrymus damn… I’m sorry to hear that man. I don’t know if it fully unscrews. Is the fluid coming out or is it still sealed? If it’s still sealed I might just use other methods to get a good amount of fluid exchange
@@T4Rgarageyeah, the bolt is broken. I'd need to get the whole Cylinder block drain cock plug replaced to do a proper flush.. so far I can only drain from the radiator. :/ There's a hole in the bolt too, so I'm a bit worried. It's not leaking, but maybe it could blow from the pressure when it warms up?
Also, while picking up the Toyota coolant grab a new radiator cap and thermostat if your vehicle is near 100k miles and look your radiator over for any signs of seepage.
Does your reservoir coolant go down time to time? Or it stays filled? For mine ive had to put just a little bit like 2xs in 5k miles. Just a lil concerned if its the head gasket
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.
@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?
You’ll be spilling coolant all over the place without the type he uses. Also burps much better with the sealed adapter to slip tip funnel kit as air will travel to the highest point which is the top of the coolant in the funnel
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.
Your method is no where near as effective. By draining block it allows you to add 2/3 capacity for equivalent 66% fresh coolant. By doing just radiator it is 33% first time but you are then drawing 1/3 volume which includes 1/3 fresh coolant and replacing it. You method is thus ending up with 55% fresh coolant equivalent (100%+33%×2)/3=55%
That’s a waste of money and time. Drain the radiator and block, get as much out as you can and just refill with the pink coolant. You’d be getting out ~2/3 of the old coolant out instead of just ~1/3 and not have to waste perfectly good coolant. The block drains are easily accessible on a vehicle this high off the ground.
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?
You’ll only drain about a gallon (4qts) from the radiator alone. Draining the engine block will allow you to drain almost another gallon. You will exchange much more fluid by draining the block
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👊🏼
@@T4RgarageGood Product, my 2023 SR5 Premium is also covered with oil based rust proof including fluid film. Just trying to protect my investment from rust as much as possible. Our winter is brutal here in Toronto Canada.
@@teddynaicker2997 I hear ya, our roads here have been terrible these past few weeks. Lots of salt being used by our municipality. Some of the salt chunks are the size of small rocks. You have to protect the undercarriage and frame on these things so they last as long as the drivetrain

On the topic of coolant flush, thank you for the video! I’m definitely going to drain the block and rad next time, last time I just did the rad.
If you have the V6 it should be the same, except you will have two drains on the block. Drivers and passenger side. You could get away with just draining the drivers side though
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

@@kimbuck-2 i listen to the toyota car care nut a lot. he says old rad fluid goes acedic . it may still cool fine but goes acedic. also said to think of it as a lubricant, which makes sense. toyota are known to be reliable but after 160k also known to need a water pump so i'm swapping mine frequently
@@kimbuck-2 camrys are tanks., i have a corolla and tundra, each 11, 9 years old im keeping them at least that long again. its becoming a challenge to me to see how long I can keep them.
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
@@lenghtofpull I wouldn’t introduce water, just because you’ll never get it all out. This means that the ratios will get thrown off when you add the premixed oem SLLC coolant. The bottle says right on it “Do not add water”
