- I demonstrate the thermostat replacement on Honda on the 2003 - 2007 Honda Accord 2.4L K24 engine. This procedure applies to Honda Element 2003 - 2006, the 2003 - 2008 Odyssey and other Honda's with the K24A engine. This was done as part of preventive maintenance on a high mileage car to prevent overheating.
Thermostats are a critical component of the cooling system. Thermostats may become stuck on or off when they fail. Ideally, a thermostat should be replaced when other critical components of a cooling system are replaced e.g. radiator, water pump etc.

Although most manufacturers do not provide guidance for replacing the thermostat, it's one of those parts that should be replaced as part of preventive maintenance in high mileage cars. Especially when critical components of the cooling system are replaced.
Short and to the point. Thanks a lot bro 🇳🇬
You're welcome!
Excellent explanation 👌
I am a huge fan of DIY Auto repair on youtube. I must confess, i haven't seen been excited with ur review since i sent my eyes on one. You are just too much at it meen!. I love u. Keep up d good work sir.
Thanks! All the best.
finally good video about this replacement!, thank you a lot bro❤️
GREAT DETAILED VIDEO.THANKS 👍🏽
Thanks!
Great helpful video, thank you so much, brother!
You're welcome!
Excellent video! Thanks
You're welcome!
Great job 👏👏
Exelent video brother.
Many thanks!
I greatly appreciate this video - I have a 2007 Accord. I can't get the bottom left screw. I've tried almost every different size ratchet and extension but can't get the necessary leverage for the last screw. I know it's a Size 10 but ..... just frustrated as I got everything drained, hose off and 2 of 3 screws off in minutes. I'll keep at it ........
Thanks! Wish you all the best. Just take your time, and try different approaches and angles.
Great job. You did excellent job. Thanks
Appreciated! 🙏🏼🙏🏼🙏🏼
Awesome job. Thanks!
You're welcome!

Ima try to fix my ,thermostat tomorrow morning,I had a leak maybe didn’t tighten the bolt . 😮 wish me luck !🍀
All the best!
I’m having trouble with my heat on my 03 accord 2.4. The blower works but the air is cold, also the temp needle doesn’t reach the half way mark on temp gauge. Do you think this can be a bad thermostat? Thanks
Yep. A stuck open thermostat is a potential culprit. Low coolant, bad heater core valve and a few others.
Good day sir, u made a review on Gumout All in one cleaner. I want to know if it works for all engine type. I plan using it on my Hyundai Elantra 2010 4cyl DOHC 2.0L. Their hasnt been any sort of cleaning done in d compostion chamber since i porchased it 4 years ago. I noticed a litle reduction in compression compaired to wen i just got d car. Can i use d Gumout cleaners stuff on it. Or is thare other types of gumout out there u can recommend i use. Thank u
Combustion engines have a relatively basic setup and Gumout should work on the Elantra once the steps from the manufacturer are followed correctly.
Bien muy claro gracias
Eres bienvenido. Gracias.
Can u tell me why the autel 906tsdoesn’t communicate with abs? It says use connector which I did still can’t comm with dodge Dakota 2002 3.9 and 2003 4.7 please help me with this
Hi. I checked Autel's vehicle coverage page, and did not see 2002 & 2003 listed under Dodge Dakota. This may be the reason.
When I got to your "lightbulb" moment on my car, that part would not budge. Had to break it and get a new one at NAPA. I swear Honda makes this hard this on purpose. Two hours later - I also could not remove the two bottom bolts. Rusted in place. Took it to my mechanic. Will never own a Honda again.
😂 🤣 🤣. That's the hardest part of this replacement! Luckily mine came out in one piece.
I have my first and last Honda. Overly complex., hard to work on, overpriced cheap plastic parts. I have had several Honda motorcycles that were topnotch but not my Element,Junk. Next vehicle will be a Toyota.
Seems like it wasn't a good experience. All the best! I have a Toyota in the family too, but I must say my Honda's have been bliss!
Yeah, those quick connect are not quick to disconnect.
😂
Thank you so much
Your welcome!
I took my 2007 accord to a radiator repair shop last week and he told me to buy the thermostat at the dealer because the aftermarket ones are crap and don't last. Can you please provide your opinion on this? Great tutorial video, thank you!!!!!
On certain parts, I only do OEM. Thermostats are one of them! I agree 100%.
Thanks for the compliment!
True. Along with radiator cap. OEM from dealer. Spending $20+ on a radiator cap is cheap compared to the headache the $5. Will give you.
Thank you
You're welcome
Good afternoon. I recently bought a honda accord 2005 model and the former owner already removed the thermostat. The mileage is at 230000. Recently we started developing overheating. I want to ask should i get a thermostat reinstalled back or thats not the reason for the overheating
It's not the reason it's overheating. You'd need to work through the causes of overheating. I did a video on this that may be of help ruclips.net/video/Jxax0Rk6NsM/видео.html
Great!
To change the thermostat, do you have to drain the coolant or can it be changed without draining?
You have to, but I would imagine it can be done without draining if you have a clamp on the lower radiator hose. I won't want to subject the hose to the stress though..
Thankyou 🌹👍
You're welcome!
Do you have to drain the coolant out before removing the all ?that please respond
Yes. You'll have to drain the coolant.
Yes. You'll have to drain the coolant.
The first time you replaced was at 250,000 miles? Thinking about doing mines at 160k..
Yep. The first time I replaced.
first issue i had was that the heater control valve broke.
The center screw came right off and started leaking coolant and overheated the car.
I replaced it and test drove it but i noticed the temp gauge was going up and assumed the thermostat stood closed since it overheated,
i also replaced the thermostat. I test drove it and again it started over heating at this point i check the radiator and i noticed a small leak from one of the plugs in the bottom.
i replaced the radiator and again overheating issues. the fans work. the thermosensor works too. any suggestions?
Sorry man. What's the color of the coolant? Milky? Head gasket could be burnt. Are you able to inspect the cylinders via borescope or check compression?
@@DIYAutoworksNG do you have an Instagram? I barely noticed you had replied. I’ll check those things out that you mentioned
@@DIYAutoworksNG when I replaced the thermosat the coolant was normal. I didn’t flush the coolant for the thermostat replacement. I just sealed the edge of the hose.
keep in mind it was the same coolant for the thermostat. However when I was replacing the radiator I did the flush & the last 2 small tubes at the bottom of the radiator were the last 2 to disconnect when I did this dark water came out of what was left I assume of coolant and that was about it.
What car is this?
Yes, I do. Search for piykediyautoworksng
what size bolts are they?
10mm
Can this also cause my car idle so high on cold start
A bad thermostat that is stuck open can cause a high idle, but "so high" is subjective. Is it a Toyota? If yes, did you reset the ECU recently, take off the battery terminals or clean the throttle body, and didn't do an idle speed relearn? Those will cause a high idle.
Bro where did you get the thermostat to buy and my fan has been made to run directly with ignition. Can you direct me on how to revert this, also can you help me buy the thermostat I'll reimburse you
Got from either Amazon or hondapartsnow.com, can't remember. Both in the US. Unfortunately, I don't run a procurement service, but there are loads of procurement services you may explore e.g. horlogistics.com/
Please do due diligence before potentially engaging them.
Can you ever sell this car. You seems so glued to it
Lol. I have a knack for car maintenance and doing it myself. Just doing what I'm passionate about and love. It's less about the car but more about keeping my car in top shape.
Both fans turn on when AC is engaged, but neither fan turns on with a hot engine with the heater going full blast. Does that mean the thermostat needs to be replaced?
You may want to look at your coolant temperature sensor/switch. I'd go there before the thermostat except if they're integrated.
@@DIYAutoworksNG I replaced both and still the fans don't turn on unless AC is engaged or the switch wiring is jumped with a paper clip. When I turn the heater up full blast, it doesn't get hot really. Maybe the water pump is the issue.
Does Thermostat help in fuel consumption?
Yep.
Boss what is the name of the OEM thermostat u bought and where can I order it.. better still can I get d old one from you since it is also OEM. Thanks
Hello,
Honda calls it "Thermostat assembly (Nippon Thermostat)". You can order it here www.hondapartscheap.com/v-2003-honda-accord-sedan--lx--5-speed-automatic/engine--water-pump-l4
It's number 8.
I actually kept the part for a buddy of mine whose Accord doesn't have a thermostat and he's on a budget.
I'd let you know if he goes with something else. Obvious caveat is that my car had over 255k miles before I removed this.
@@DIYAutoworksNG
Alright thanks sir , I just bought used 2005 Accord .. I have been following you on RUclips, nairaland and blog long time ago..
I will be looking up to you for some questions if you don't mind sir.
Congrats on your new car! Also, thanks for following! Will be quite happy to be of help any way I can. All the best!
@@DIYAutoworksNG boss has your buddy taken that thermostat ? I am still interested
Taken, boss. Hope your car has been good?
Where do I buy this thermostat?
This was either from Amazon or hondapartsnow.com
Is it the same on the 2009?
I haven't worked on the 2009 but it should be roughly the same. Same K24A engine.
Will this cause ur radiator to leak? At the top and cause ur engine to overheat???
A blocked thermostat will overheat an engine. Not sure about causing radiator leak but plausible, though I think radiators leak mostly from ageing.
@@DIYAutoworksNG ok a blocked thermostat , I get that part but what about will that also cause it to leak at the top of the radiator near the top hose
Are these bolts known to snap im worried ill break one
Haven't seen one snap, but not impossible. Though I don't think you should be that bothered. Is it rusted in place?
@DIYAutoworksNG ill take a look later on but the car is at 220k+ miles and according the dealership papers and the last owners the water pump hasn't been touched since it was bought over 15 years ago
Hey boss man you never gave the torque specs for the thermostat bolts.
Hello. Just double checked. I gave the torque spec from 4:30 onwards. Its 10Nm. Cheers!
Should have change the upper and lower hose too since the car is so old.
Very fair preventive point. However, I would replace those only if they show signs of wear. They were still in good shape despite being old! The recommendation from Honda is to replace if they show signs of wear. Great point though.
Bro... How much is a Thermostat costs actually.? Please get back to me I need to replace mine
Varies. Just check Amazon, dealer websites (e.g. hondapartsnow.com), Rockauto to mention a few.
Turtle nose dives into a Castro😅
🤣
You completely failed to mention all the stuff you had to take apart to get such a clear view of the thermostat.
I only took out the things shown in the video, nothing else. I used a mobile phone camera for this video. Works better in tight spaces than a mirrorless camera or DSLR.
