How to Flush Cooling System in Your Car - Easy Radiator Coolant Change DIY - 2015 Honda CR-V

[@romanroque8866]

I just got a little over the 100k on my crv-2014 and for some reason this pop in my head for things to do thanks for the amazing video

[@110897100]

Appreciate it Man. Thank u

[@starkeymorgan4142]

Definitely time if you haven't done it.

[@le150gj]

Technically not a flush, just a drain and fill.

[@user-Rsmlopasc]

How did you take off the coolant reservoir bottle? Please help, im scared of breaking it!!

[@tomkoolman]

A quick tip. I would squeeze the coolant hose before removing the anti spill funnel to ensure all air out.

[@110897100]

Thats a good Tip brother! Thank you!

[@gordonbushell5964]

Thank you. Exactly what I wanted to know. !

[@r_x004]

so no need to wash the system with deionized water 1st before filling with new coolant?

[@Zz2424zxcvbnn]

This is the best and most detailed video I’ve seen yet, thank you! May I ask though, as I do not plan on using the method with the extended stationary funnel you used here, would I first fill the radiator to full with new coolant and the reservoir to half way ? Also, while burping out the air, does the radiator cap need to be open? One video mentioned that you have to close the cap while burping the air out, wasn’t sure! Thank you for any advice you can offer

[@rickleger3528]

Outstanding video helpful and very professional as well great job this will help me do a better job thanks

[@110897100]

Thank you brother

[@garyboyh]

There's a sticker on the hood that you should change your coolant based on maintenance reminder code or 10 years whichever comes first then every 5 years after. Too early to change the coolant. Good video anyway

[@110897100]

You are right brother. My honda dealership recommended to change for preventive maintenace. So i did myself. My bad i didnt read the sticker before i change the coolant😅

[@r.c.850]

???.. my car is 2017 with 110,000 miles. and I saw reservoir is empty, I not sure the level of coolant in the radiator, ... Question: Can I just add to fill or its better to flush all and put a new one? ....

[@Woodra_YT]

Thank you!

[@dellkickass]

I have questions. Can we just don't turned heater on for engines getting hotter faster and wait until fan kicks in , then we turned heater on maximum speed later.

[@TheAikiToneRanger]

I have two quick questions: - This looks more like a basic change than an actual flush. - What are your thoughts on doing a proper flush and changing from the Honda OEM coolant to (gasp!) an aftermarket coolant so you can upgrade to a HOAT coolant?

[@110897100]

Basically this is only my first try to do the flush. Iam not really a mechanic but i love to do the basic maintenance of my vehicles. I dont know but i might just use honda OEM for my cars😀

[@TheAikiToneRanger]

@@110897100 Great video! The general issue with upgrading from an IAT or OAT coolant to a HOAT coolant is that you need to fully flush out the IAT or OAT first. While generally speaking HOAT coolants are superior because they last longer, the further issue specific to Honda is that Honda does specify to use their (or at least a comparable) non-silicate non-borate coolant. The issue with the silicates is that they precipitate and act as an abrasive in the coolant system. In an iron engine they're supposed to absorb into the surface layer of the coolant passages and coat the cooling system to prevent corrosion. In an aluminum engine like the Hondas, they don't absorb and begin to collect around rubber bits and edges, consequently causing leakage premature wear. HOAT coolants, while longer lasting, do tend to have at least low amounts of silicate. So aside from needing a full flush to make the change regardless, there's also debate as to whether they are actually superior for the Honda engines' coolant system, or if it's actually better to stick with the not as good but perhaps more fitting Honda coolant, or at least something that fits the description closely enough.

[@110897100]

@ The Aiki Tone Ranger Thank you for your very informative ideas. Do make sense to me😀..I need more of this to learn more😀. Thank you and i really appreciate it. Godbless

@ The Aki Tone Ranger Thank u brother. Keep safe and healthy too in this difficult times..

[@DIYJIM]

very nice video I'm going to change my CRV cooling. How many gallons of OEM Honda coolant did you use?

[@110897100]

Thank you.. about 1 and 1/2 container of OEM Honda coolant. Just dont turn the engine off untill the radiator fan kicks in..While filling in coolant try to squeeze radiator host..

[@frankfromupstateny3796]

Nice job...do you suggest...running...them flushing again...or just drain. Squeeze hoses...drain...put drain plug back...open up heater core for an hour...add more fluid...etc?

[@DrKniz]

So can we do this without that self burbing bottle by just leaving cap open and topping off as needed?

[@user-bp5jv1fp4t]

I want to know, too.

[@DrKniz]

@@user-bp5jv1fp4t I did it that way without any problems..

[@schemeteam2954]

No because it'll spill out when it gets got unless u make a funnel with tape in the bottom where u fit into the radiator.

[@holycow3355]

I enjoy car diy as much as cooking, which is not a lot. But may have to do myself as if take the car to a mechanic, even pay for OEM fluids, they may just use cheap generic stuff !

[@110897100]

I do the same. By doing your self you are confident that you are using the right fluid and right amount needed to your vehicle…

[@erick_rivera7261]

i’m doing it right now, after i started the motor the coolant level went a little down and now is hot, once the fans kick in should i full it again, then close the cap and turn off the engine? thanks for the video.

[@erick_rivera7261]

the fans started al 25 minutos more or last and the they turned off, i filled it again and turned off the engine… was it done correctly?

[@110897100]

Yes fill it.. once the fan kick in, we are sure that theres no more air in the system.

[@erick_rivera7261]

@@110897100 thank you so much!

[@lambcor]

Excellent video, a question if someone can answer me, how do you prevent the antifreeze from filling the reservoir through the small hose while you fill the radiator?

[@110897100]

In this case it could be a bad radiator cap.. check also the thermostat and water pump. But first check radiator cap. Or maybe your radiator itself is malfunctioning.

[@edubb2491]

When the engine is off..their is no suction..so while pouring..it will go straight into radiator

[@metzmatu8409]

Just uncap the reserve tank and whole it up, with the tube higher then the radiator opening, while pouring/filling the radiator. (defeat the gravity of fluid going into the reserve tank with hose higher then radiator open mouth.😄)

[@rodrobinson6111]

I have a question for u. BTW, thanks for the informative video. My drain plug is on tight. I’ve tried using pliers to turn it, but it’s not moving. Do you know any other tools I can use to get this plug to turn? Thanks

[@milkmancow5]

Try spraying it with wd40. Let it sit for a while and then try turning it with a pliers.

[@johnnyzang308]

Hi Bro, thank you for ur video! Very nice! I have a quick question: after fan turns on I squeeze the hose and air bubble comes out, and fan stops. Then I wait for extra 30 min and notice that fan turns on and off. Is that ok? Does ur fan always on?

[@110897100]

Thats preety normal bro. No problem. Dont worry. Bubble came out and fan turned oN so theres no more air in your system.

[@metzmatu8409]

Why waiting for 39 minutes when you can raise the rpm to 3,000 RPM to raise tge engine temp faster, 3-5 minutes with do it. *Take note, don't rev a cold engine highr then 4,000 RPM.

[@110897100]

@@metzmatu8409 its my first time to do it😅😅.. i will do that in the future😅😅.. many thanks

[@SeahorseWorkshop]

Nice going. Exactly what I needed. Why it took 1.5 hours for the fan to turn on? I think you could leave the fan knob in off mode (not turned to blast mode). I am going to change my coolant today.

[@110897100]

I did turned to blast mode. I suspect i didnt squeeze the raditor tube while filling up coolant resulting to have air in the tube. I guess thats the reqson why it took a while. The fan finally turned ON after squuezing the radiator hose.

[@edubb2491]

Mine turned on right away..lol..so..I didn't have to wait till fan turned on..I jus let it run to operating temp..then another 5 more owns jus to make sure no overheating..yea with in 1 min of idling my fans turned on

[@roberthouston3809]

Would this be the same for a 2010 CRV?

[@110897100]

I believe so. Both are hondas. Just do the same procedure.

[@maureenaba7149]

Nice one.

[@110897100]

Thank you Mau😊..

[@sunflowers3393]

🙋‍♂️ what if the fan not turn on I wait for 1 hours the radiator fan not kick in so I turn the engine off any change the air inside the system?

[@110897100]

@Bong Xinh - yes! Most likely theres an air in the system. You can try one more time. Remove the radiador cap and turn on engine with Heater on High. Squeeze the rubber hose on the radiator because there could be air in there..You can step the gas with 3,000rpm also. I’ve waited 1 1/2 hours before the fan kicked in on mine

[@sunflowers3393]

I leave the car running 2 hours long finally afterwards the fan kick in .phew

[@110897100]

😀.. im glad! Now you are now confident that your cooling sysytem is alright! You know air in the cooling system might cause problems in the future.👍well done brother! Make sure coolant levels in the radiator and coolant resovoir is right

[@reginaldsmall3766]

@@110897100 you don’t have to idle engine1 1/2 hrs. I just changed my antifreeze and I let it idle 10 min. With heater on and drove 2 miles .1. Drain antifreeze 2.
