Toyota Tacoma Coolant Change // Easy Tutorial From A Technician 

Great videos man. Can't tell you how much I appreciate you taking the time to explain everything thoroughly. Adding the extra "if this happens then do this" or "watch out for this" type stuff really gives those of us who are learning some confidence because we already know what to watch out for, instead of having to find another video to explain what went wrong and how to fix it.

Just got a 2014 tacoma This guy make the best tacoma maintenance videos👍🏾

Ran by this in my suggested videos solid quality. I am 100% on board with aftermarket coolants and I do coolant swaps every 50,000 miles. As my grandfather said when he was still here. Oil is cheap iron is expensive. (I get we aren't dealing with oil and the 1GR-FE is an aluminum engine but you get the point)

Best change video that I've seen so far. Now I can change it in my 2011 Taco with 197,000 miles without a change!

Very helpful. Before putting the stopper in the funnel, I squeeze the upper hose to push a little fluid back, then put in the stopper. You won't lose a drop! Thanks for all the great videos; I have learned a lot from you!

Great video! I have a 2nd Generation (2005-2011) Tacoma with the 4.0 Engine. After draining the radiator, you will find a "block drain cock" on the left side of the engine slightly above the starter. This should be drained also. You will have to remove part of the inner fender well plastic cover to see it. Next there is a "block drain cock" on the right side of the engine block. It must be accessed by getting under the truck. Both drain cocks required a 10 MM socket or wrench. Sock with an extension works the best.

Thanks bud! I got a 15 and your videos are informative!

Thanks for this video. Thanks especially for adding the note about of your don’t have the plug funnel. Great video!

Great video. If you are doing this at home, make sure no pets are around the coolant. It is very poisonous, and dogs are attracted to the sweetness of it.

Thanks for this video. I will for sure need to replace my radiator fluid ASAP.

Thank you! This video will save me a trip to the mechanic and save me money too!

I did a flush, added a thermostat and temperature sensor at same time, truck idles lower / smoother , seems to run better and get better fuel mileage

Thanks for another great Tacoma video, glad I found your channel. Glad you also posted the kms for changing the coolent, I'm overdue at almost 200000, I better do it before it gets too cold here in nova Scotia!

Thanks Kelly!!! I’ll check back and read all comments. Too many times I have dealt with trapped air.... what a pain and any hot air pockets up high can’t be good. I guess you could say I now have a phobia about trapped air,,,,, and no experience yet with pulling the system into a vacuum.

Thanks for putting this out here. Much needed

Another thing that everyone should do is also flush out or blow out the radiator fins and a/c condenser from the inside out on a regular basis or more often the in dusty dirty conditions. There are also spray cleaners that are made to clean out radiator and condenser fins. But make sure you read the directions if you use those products. You can also wash out the radiator fins when you are at the car wash. Just make sure not to damage or lay the fins over.

Back in the day we just squeeze the top hose a few times and fill it. when it went low add more fluid. Tell it was at the top. Drive it around the block let it cool then check it again tell there was some fluid in the reserve.

Another great one!👍👍

Nice and detailed. Thanks

Excellent, thank you!!

awesome DIY video! Now I feel confident to service my 2010 Toyota 4Runner coolant just sub to your channel thank you!

Thank you Sir. Good deal.

Good job!

great video thanks for making it

Would you recommend replacing the thermostat when doing a flush??

Great vid man thanks! I have a 2015 Taco V6 4.0L at 80k miles and noticed the coolant was a little low so I filled it to the full line with OEM coolant but I poured it straight into the reservoir instead of from the radiator. Is that going to cause an issue? Thanks again

Can't wait to share this w/my daughter... Faye! LOL! You mentioned, "way eariler than 50k change interval". Totally. My 2015 Taco 4X4 w/2TR-FE engine has 42k and I can't believe i'm just getting to this now. Gonna run the truck w/a coupla gals of distilled water before I refill w/Xerex. Amazon price for Toy coolant is $33/gal now. Uhhhh, no thanks!

Great video, thank you, I have a 12 Taco that needs service. Is it possible to do the old school full flush like I used to do on my Jeep CJ? As is, hose in rad, motor running, lower hose unhooked, or something similar to flush the block, heater core, entire system?

Hello, I have a 2008 Tacoma Base, and I have to change the water bypass hose or as it is known in English "Water Bypass pipe" (which is made of plastic and already has a coolant leak) and I came to your video because I wanted to take advantage of doing a wash on my truck, since I also have to drain all the coolant. It is one of the simplest videos I have seen since it is practically draining and filling, although I still have doubts regarding the fluid left in the block/engine, remembering that my truck has 162,000 m and I honestly believe that they have never changed that fluid. Hola tengo una Tacoma 2008 Base, y tengo que cambiar la manguera de paso de agua o como se le conoce en Ingles "Water Bypass pipe" (la cual viene de plastico y ya presenta una fuga de refrigerante) y llegue a tu video porque queria aprovechar de hacer un lavado en mi truck, ya que de igual forma tengo que drenar todo el refrigerante. Es de los video mas sencillos que he visto ya que es practicamente drenar y llenar, aunque tengo aun dudas en cuanto al liquido que queda en el bloque/motor, recordando que mi truck tiene 162,000 m y honestamente creo que nunca le han cambiado ese liquido.

Thank you

What about the remaining of coolant that is in the engine chambers, doest drain all out or not? Thanks..

Nice TSA shirt and gloves

When adding coolant again the next day like you suggested, do you add it back to the reservoir or should I open up the radiator cap again? Great video! I just did my 2013 4runner with this with perfect results :)

Question? I know you had the throttle around 2000 rpm’s, but shouldn’t you also just turn your heater on to circulate fluid in your heater core as well. I would think now might be a good time to change out your thermostat as well since your draining all the fluid out .

Hi, drained the coolant from my 2009 v6 4.0 Tacoma this weekend. I barley got a 3/4 of a gallon out of the radiator drain and passenger block combined. Engine was cold, radiator cap was off before I opened the drain. Only thing that is different is that I connected a plastic rubber hose to the radiator drain outlet so it wouldn't make a total mess. I did open the plastic drain plug almost fully off though. Any reason I only got 3/4 of a gallon out? I just got drops from the passenger side block. I didn't do the driver's side. I refilled with about the same amount of fluid I got out. Burped it and zero issue on my 30 min test drive.

How hard is it to remove the drain plugs on the block? I'm afraid they will strip so I was going to just do a couple drain and refills.

2008 taco with 121k miles and original coolant. Never had an issue, but now its bothering me mentally. I think I'll finally do it.

If I replace the water pump the block will definitely be drained out right. I don’t want to flush the block out, is it ok if I just fill the coolant back in without flushing the block out? Thanks 🙏

How many gallons did you end up using? I’m currently doing this and it has yet to accept a full gallon after revving

2015 Taco here as well Im at 46k, time for a drain yet? You mentioned 100k Also how many bottles of coolant did you use? Was it premixed 50/50 or?

Great how to video,I was wondering will changing the color of coolant do harm to the engine of my 2012 tacoma,or should I stick the factory coolant.

I drain my coolant out. Flush it with water running while engine is on. Is it safe for now a day car?

Hi there was a very nice video and I like to ask how many gallon of coolant you used one or two and the mind time I have a 2014 Toyota Tacoma SR-5 close to 95,000 Miles I never have any issues so far is Automatic thank you for you tima and be safe a 100% please send me a respond if you can Adios!

Did this truck have a motor coolant drain on the passengers side that should be opened, drained, and then filled at the radiator? Thanks.

How many gallons of antifreeze does that Toyota Tacoma take?

Is there a reason why you didn’t drain it from the engine block (The drain by the passenger tire) ?

Is using a radiator flush chemical recomended?

What about the coolant in the engine block?

Thanks for another great video.Is it normal to hear gurgling sound after turning off the engine?I have the 4.0L engine if that matters.Dealer replace my AC compressor assembly and don't know if they needed to pull out one of the radiator hose for easy access.I can't remember my truck doing that before.Coolant level is okay.Temperature is okay.I dont hear it while driving.Can just hear it after turning off the engine.

Does this apply for 1st Gen Tacomas too?

Can you just turn the heater on if your by yourself

With proper maintenance your Tacoma will last a long time so Just get the Funnel and like he stated change it more often than the 100,000 mile.

Is it not necessary to flush the whole system with distilled water prior to putting in the new coolant?

Great video. Is it pretty much the same with a gen 3 tacoma?

Engine coolant drain plugs?

How much coolant did you use

Is it the same process for a 3rd gen tacoma?

Do you have a video of doing the serpentine belt. I have a 15 Tacoma to.

I was wondering about draining the block or does that not apply to the V6 version? I have a 2.7 four cylinder and it has a drain on the block.

I’ve heard you can also turn the heater on.

What about the old coolant that's in the engine block? Could I use Distill Water to flush out the old coolant in my engine block? I have a V6 4.0L 2013 Tacoma TRD Sport 4x4 Double Cab.

Isnt time/age important too? Coolant thats 2/3 years old vs miles?

That funnel makes a big difference when working alone.......and a pedal depressor.

2010 tacoma 2.7....drain and refilled ..no air lock problems

? does the rusted rotted Gen2 skid/splash undercarriage plate NEED to be removed to access the drain on the bottom of the radiator? TY!

Question for Kelly. I have a 2004 V6 4Runner SR5 with single climate control. When running the heater, the air on the drivers side is much warmer than on the passenger side. What can be the cause of that? I replaced the temperature blend actuator and the mode actuator is working fine. Any ideas? Thanks much!

By any change would it be possible that it is not necessary to wait for the bubbles go out with that type of funnels, because it has the reservoir tank, where the bubbles con go? I mean, what if we drain the radiator, re-fill it up, with the reservoir tank included, and then start the engine, and use the reservoir tank as an alternative of the anti-spills funnel, and then at some point when the operative temperature is reached, and thermostat opens and start the flow, the bubbles trapped inside will travel at some point to the reservoir tank and get integrated with the rest of the air in the reservoir tank. If not, what if we leave the reservoir tank opened until that happens?

I have a question on what position you put the temperature indicate on cold or hot if you put on hot you settle it on run or off

This is a great video explaining things step by step for a drain and fill. Would these steps in the video be the same for a 3rd Gen Tacoma? Also, notice the engine block was not drained. Should that be done or is it optional? Again, thank you for taking the time to make these videos!

Yasss

Nice job on the vid. I have a 2011. In the "old days" as you call it I used to do this with the heater opened full. Would you recommend doing that with this type vehicle or does it matter? Thanks!!

I've seen the video, but my question is this: How many quarts go into the cooling system?

just watched your video...Running a 05 tacoma 4.0, recently purchased and discovered the green coolant in there. Its not dexacool, but there seems to be controversy using this universal coolant instead of the pink/red toyota one....Any thoughts on that? much appreciated

What's up with flushing out old pink fluid and replacing with universal all models coolant. Should I keep flushing til pink changes clear, then add universal coolant. I've heard not to mix different antifreeze/coolant.

Doing this procedure when did you add coolant in the coolant reservoir?

When do you remove the funnel? When engine still running? Or turn off with funnel in and wait till it cools?

Question is this the same for a 3rd gen tacoma? Bc im about to change mine

Why didn't you drain the antifreeze from both sides of the block after draining from the radiator? I got more out of the block than I did from the radiator.

How much coolant did you use?

It would be incredibly helpful is you did this with a 2016+ / 3rd Gen Tacoma as well.

Is this the same on a 2006 Tacoma 4.0L V6? My mother in law asked me to do this for her and change her thermostat.

I have a plate I need to remove below my radiator ( engine ) to even get to the drain plug. It has 4 bolts I have to remove 🙄

Are there any differences on this process for the 3rd gen?

Is flushing necessary or can I just do what you did? My Haynes repair manual says to remove the thermostat and do other stuff to flush which seems unnecessary at 50k miles. What do you think?

Imma go ahead and go ahead...

If the reservoir is low should I fill it directly in the reservoir or in the radiator itself. Thanks

So for the record, 2015 Toyota oem coolant is PINK correct ??

I think we should trade lifts. I have a sick floor jack 😂

You are also supposed to put the heater in the highest temperature

Isn't there a drain on the engine block? What about that?

🙂👍

You MUST DRAIN THE BLOCK!!! It is EASY on the 1GR-FE - Open the drain petcocks. Regarding coolant, Pentosyn Pentofrost A4 = Toyota SLLC. DON'T USE ZEREX, or PRESTONE.

first things first...where is your washroom ?..I was hoping to see a Toyota tech doing this

What about draining the block ?

Did you have to turn on the heater?

How would you do a complete flush?

Don't you TURN HEATER......ON, so you can circulate the COOLANT through the HEAT CORE?

Thank you, Tony Stark!

From someone who works at Toyota you dint even talk about if you should have your heater off or on or your defroster.

Antifreeze 100 or 50/50
