I have a 2004 Honda Accord. All your videos are very helpful and easy to understand. You are truly an asset to the DIY's. Thanks for all you do. I wish you had a repair shop near me.

Thanks!

@@NutzAboutBolts hey man I did this but my accord had green coolant before I flushed it and put blue in it and after I put blue in it the whole coolant burnt thru the exhaust what did I do wrong the coolant was the right type I put the blue Honda coolant can u help me out???? Thanks man

[@AG-ux9mn]

@@bryanc2608 If you did not flush the green coolant from the white resiovor, you'll end up mixing both coolants.

[@AlexAyoub_]

For anyone using this kit from Amazon (I purchased in 09/2021), the fitting for Accords of this year is actually the B fitting now. They have since changed the funnel to be smaller and the C fitting (at least in my case) plastic piece fit in fine, but you will find the metal adaptor that acts as the top of the radiator cap no longer fits. Even if you try and force it to fit (yes, I did this like a moron), it does not force the plastic part down to create a seal. Instead, the B fitting has the perfect fit now and the plastic portion has a lip on it that, when you secure the metal top, forces the plastic part down and allows the rubber to create a seal. Just wanted to update people who have purchased the kit since this video was made. Always helpful videos though, so thank you! :)

[@vincentcleary3891]

Hi can you tell me the name of this kit? Based on another u-tube (2012 accord) video I believe it's Lisle 24680 but I need to be sure before purchasing. I have a 2007 accord 2.4L. Thanks.

Yuchin Cheng but they did not show how they drained the overflow tank or if they even did!

[@NutzAboutBolts]

@@jogmas12 when you drain the coolant from the peccock, the vacuum will suction the fluid out of the reservoir. If you want to thoroughly clean the reservoir, there’s a bolt or a clip that is held onto the container and you can remove it to drain the rest of the fluid out.

[@jogmas12]

@@NutzAboutBolts thanks. I have a quick question, I have a 2006 accord with four cylinder. I put a new power steering reservoir, and put the two new low pressure hoses leading to and from it, however .... the bottom of the reservoir is still wet from from power steering fluid. Why do you think this is happening?

Heads up for anyone doing this, please make sure u only use the genuine honda coolant or you will rust your coolant lines then overheat and warp your engine head.

[@Esuper1]

Good job showing us the procedure. It does help alot. It would be nice if honda sold kits which included all the needed parts and stuff. It would also help if the amount of coolant sold was exactly what the drain and refill needed to avoid the waste of having coolant left over which will probably be stored and lost or simply thrown away.

[@HaroldJohnson]

Great video. I just lost a lot of coolant while replacing the starter (had pulled the coolant lines from the throttle body) and added blue Honda coolant but I believe the coolant that was in there was green. I’m really nervous about running the car with both those coolant types mixed together so going to be flowing your procedure if I decide to change the coolant entirely.

[@NutzAboutBolts]

It should be fine, I wouldn’t worry too much about it since the green is aftermarket coolant, may not be oem but it’s still coolant.

Two questions. #1 If you have the funnel on and waiting for the fans to kick on to remove the air, you mention you can drive around for 15-20 min to get the fans to kick on then turn on the heat. How do you do that with the funnel on. And if you put everything back together then drive around then turn on the fan how does that remove the air in the system? #2 can i turn the heat in the car on full blast while the car is running before the fans kick on? What is the negative of this?

Tim Kwok you can if you want to fully flush the cooling system. This vehicle coolant is OEM so the system still looks good since we've taken care of this vehicle well and didn't see any build up of sludge or grime. So we opted for coolant drain and refill. If you saw our other video on the honda civic, we did drain and refill 3 times with water to flush out the cooling system.

[@NutzAboutBolts]

if your fan doesn't turn on, you should check your upper and lower radiator hose to see if its hot or not. If the upper hose is hot and the lower hose is cold, that means the engine is not hot enough for the fan to kick on, when the upper and lower radiator hose is hot, it means the engine is hot, the thermostat is open and the radiator fan should turn on to cool the engine down. That's when you turn the heater on so it can flow through the heater core.

does the drain plug also drain the resivour tank? i have a 2015 accord 4 cyl. and want to do it myself rather then pay the dealer 200 to do it. the owners manual says it takes 1.5 gallons. Is that 1.5 gallons in the radiator, plus refilling the tank? Or is it 1.5 gallons in the radiator and tank? thanks!

[@kunalhuhu]

my car is basically the same set up, with the small tank right next to the radiator

[@nuothe11th]

Draining fluid will also drain the reservoir but only if you don't open the radiator cap while draining (the draining creates a vacuum which sucks the fluid out of the reservoir). It is probably quicker to just remove the reservoir and drain it by hand even tho those reservoirs can be in an annoying spot. It's probably a good idea to just drain it by hand and rinse it out since it is a spot for sediment to collect. The 1.5 gallons is for the whole system, not separate from the reservoir. The reservoir is just a place (edited) for fluid to go when it gets hot and expands (pressure increases) after running for a while/on a hot day/when standing still and the fan is the only thing blowing air over the radiator fins. Then when the car cools off, the reducing pressure of the system sucks some of the reservoir fluid back into the radiator. If you use the funnel as shown here, the space in the funnel acts as the reservoir - the reservoir itself won't fill (maybe a little that gets around the adapter tube) during the fill - that's why you gotta do it manually at the end, but I'd argue you don't need to fill it to the max - especially if you forget to use the heater during the fill (edited) or fill it on a particularly cold day and don't let the engine run very long while filling the radiator - but that's why they have extra space above and below the min/max lines. It's a pretty foolproof system.

[@NutzAboutBolts]

Touche :)

[@Brotherjaweed]

Do you have coolant in the reservoir while filling the radiator?

[@jtk49]

so can i add water first to fully flush out the old coolant and repeat it for 2,3 times; then add honda coolant at the end. Also, how do you take old coolant from the reservoir?

[@NutzAboutBolts]

+jtk49 if you're going to do that, add in 100% concentrated coolant, or else if you add 50/50, it'll be diluted to 25% coolant and 75% water since there is 100% water in the system already.

[@nickv4073]

+jtk49 There is no need to fully fully flush out old stuff. That is a myth. Just drain and fill like in the video. As for the reservoir, you can use a cheap turkey baster to suck out old stuff.

[@NutzAboutBolts]

Nick V well, we only recommend a flush if you have non OEM coolant in there that is causing mold in the cooling system. As for removing the fluid from the reservoir, you can pull it up and out from the place that its on. You don't need a turkey baster to suck it out since you can remove the reservoir and clean it out with clean water.

[@nickv4073]

+NutzAboutBolts When you're right, you're right. Sometimes I forget that reservoir comes out.

[@josiemacdonald4023]

Can you mix old Honda green coolant with the new Honda blue coolant? The dealerships only have the blue stuff.

[@NutzAboutBolts]

Green isn’t Honda coolant. Flush out the green and replace it with the blue.

[@KINGSALAMI8INCH]

What if cooling fans stay on, could that be because the car has no thermostat, and what is procedure for this case?

[@claytonclark6851]

Thermostat lets coolant into your engine block so no it’s not that

[@kvang254]

So I'm planning to do my coolant change in a few days since I'm at about 110k and I bought two of the 1 gallon honda blue coolant. I used maybe a third of one gallon just to keep my coolant levels good. Do u think I'll have more than enough with about 1 and 2/3 gallon of honda coolant?

[@kvang254]

[@supersabrosinho]

Sounds like Walt Jr decided to launch himself into an automotive technician career

[@jamescc2010]

Is it better or necessary to do complete flush instead of drain/refill?

[@NutzAboutBolts]

you do complete flushes to get rid of any left over gunk in the system. If your system is clean and you know there's nothing dirty in there, you can just do a drain and refill.

[@86banks47]

I've got Pentofrost A3 recommended from Napa Auto is that the right kind for 2004 Honda Accord LX sedan 2.4 liter? also how do I flush it out? because I had green antifreeze in it other times they gave me was blue.

[@86banks47]

I meant it has green antifreeze and I have blue to put In it....

[@NutzAboutBolts]

Napa should carry Honda blue coolant, not sure about pentofrost.... Flush out your green coolant by doing the drain and refill 3 times...

[@86banks47]

+NutzAboutBolts drain and flush using distilled water?

[@NutzAboutBolts]

no, you will dilute the coolant even more to 25% and 75% water.... the 50/50 blue coolant is already mixed.

[@Patrick94GSR]

I have got to get one of those funnels. I've been draining and flushing coolant in cars for the last 15 years with only a little 99-cent funnel that fits loosely in the radiator cap opening. It's terrible, always makes a mess.

[@NutzAboutBolts]

yup, this funnel is a great investment. You will never spill any coolant again lol

[@thesupernormal3720]

You make some of the best videos your detail and how you show the whole process really helps. I got a question if my coolant resivoure starts at the minimun when cold and when the car is at normal temperature the resivoure fills up to the half way mark what does that mean , is it normal?

[@marckjviernes4489]

I have odyssey and I'm the second owner and I have no idea what kind a coolant they used so any advise what to do?and what kind? coz I'm just afraid to mix a different type coolant

[@NutzAboutBolts]

+Marck Jerney Viernes Honda uses the Blue Coolant, the blue coolant is already mixed with 50/50 and it should say it on the bottle. If you are in doubt, you can ask the Honda parts guy and they should know.

[@marckjviernes4489]

+NutzAboutBolts hi sir so i change my coolant and thermostat as well.. I waited like 5-10 minutes but the fun didn't turn on so I just turn on my heater (max) and waited my fun turn on but it didn't... I have hot air and my temperature was on normal (drove it for 30 minutes) why my fun didn't spin if I have my heater on?

[@NutzAboutBolts]

Marck Jerney Viernes I would recommend redoing your coolant drain and refill then. The reason your radiator fan doesn't turn on is because your engine isn't hot enough. Just make sure you're doing the job right, especially putting in the thermostat properly, or else it'll over heat if the nipple was placed in the wrong position.

[@theotful]

+NutzAboutBolts I had this same issue. I flushed the car and filled it with distilled water to flush it. I turned the engine on and waited 15 minutes but the fan never kicked on. Also the header stopped blowing hot air. I started revving the engine a lot and engine almost over heated so I turned it off. I then burped the system and filled it with more water, and tried again. The heater worked fine, and the engine will not over heat, but the fan will not come on. The only way the radiator fan comes on is with the AC button turned on, but it only comes on for a few seconds at a time. Does this mean my radiator fan has a broken component? Do I need a new thermometer? Could my water pump be broken? Why would a fan never come on even when the engine is hot?

[@NutzAboutBolts]

+theotful if you just have the engine on and running idle, it'll take 30 mins for the radiator fan to kick on. If you rev. it at 2k rpm, it'll be on in 15-20 mins, if you drive it around on freeway miles, it'll turn on 15 mins. When you turn the AC button on, that's the condenser fan, not the radiator fan. The car has 2 fans, one is the radiator to cool down the engine, the other is the condenser fan to remove heat from the A/C system.

[@taz211lama]

hello pls help me..ok so fan wouldnt come on, and there is small amt of smoke from around the left side fan.. i tested the fan motor and its working fine, such a headache

[@NutzAboutBolts]

There shouldn't be any smoke coming out of the engine compartment... Can you upload a video for us to see?

[@NutzAboutBolts]

tash lam If a working fan wont come on, its either bad thermostat, fan switch, or relay.

[@taz211lama]

NutzAboutBolts oh wow, thank you for the response..you are the first one that actually replied..i posted so many places..anyway i will try and upload the video but as far as smoke i think its more like old antifreeze burning off, because i didnt use the spill free before and had a lot of antifreeze spill over...but i will see if i post a vid after i check fan switch and relay..i am scared and not good with electrical stuff...but i am going to give it a try..the thermostat i tested with boiling water and it opened up..so i think the thermostat is good..as far as the fan, i tested the one on driver side with alligator clips and it worked fine, but when i did the same thing on the passenger side it started sparking and burning the clips lol..after that i gave up..but i will go and try one more time..not sure how to test the relay..i looked at the fuse box and felt pretty dumb...no clue what i am looking at lol...but i really want to thank you for responding.

[@NutzAboutBolts]

tash lam check that fan from the fan switch for sure, if fan turns on from there. that's it.

[@taz211lama]

[@themachine8009]

Why can’t I have the heater on right away before the fans turned on?

[@ericcraighead9158]

Not 100% sure but Iy guess would be having heater(another coolant circuit open) would divert coolant away from motor and up into heater core which when not at 100% full capacity, could cause the motor to slightly overheat.

[@Esso2o2o]

What is the use of the reservoir? Im sorry if its a silly question. Just curious.

[@NutzAboutBolts]

Esso Janahi Its to keep coolant from over flowing or spilling and it helps the coolant system suck in more coolant when its low while running the engine.

[@Tanganyi]

Is it half coolant and half distilled water? Or all coolant?

[@NutzAboutBolts]

the Honda blue coolant is already 50/50, so you don't need to mix anything. Just pour in as in.

[@nabsansha]

Could anyone tell me that there is a pipe with blue cap in my honda accord 2004, i was thinking that i could add coolant from there but i saw on this video adding coolant fron the another place. so what is that pipe for? what do i add from there, is water?

[@NutzAboutBolts]

+Nabin Shrestha you can add coolant through the coolant reservoir, that is fine as well.

[@australianmade2659]

Are you talking about the window wiper water reservoir. Blue cap is water.

[@NutzAboutBolts]

Rationalist Society No, its that bottle right beside the radiator. You can see it in the video. You can see the blue coolant is inside there. The blue cap on the left side is the windshield washer reservoir.

[@HeyitsJose]

Can I use the peak brand coolant found in my local autozone instead of the honda? Peak comes in blue as well

[@NutzAboutBolts]

I'm not too sure about peak, you can read the info in the back and see if it's compatible with Honda or not, some of them say it. Blue doesn't always mean it's for that vehicle, it's an after market brand so just read what vehicle it's compatible with.
