Honda Civic Runs Hot, Overheating, cooling fans not coming on, cooling system 8th Generation

[@johnsitar7871]

Thanks again for another well thought out video for the DIY'er. I'm constantly picking up knowledge and tricks from your very informative videos.

[@dannysdiygarage]

John, I always appreciate your comments, thanks so much for your kind comments 👍🏼

[@marcomanzano6865]

Thank you very much for teaching us about the fans and cooling system 🙏

[@dannysdiygarage]

You bet!

[@HiFiInsider]

always keep an eye on the engine temp to avoid blowing the head gasket. I need to find a good OBD1 tool.

I really liked this video. Very informative. Now I just need to save up for a good scanner. Thanks Danny, really appreciate it.

Greetings from Veenzuela, excellent explanation of how it works, but I have one detail to see if you can help me. I have a 2007 civic, it does the entire cycle, only the fans turn on at low speed, and the water reservoir begins to bubble, the cycle does so at 96 degrees Celsius and ends at 92 degrees Celsius, if I turn on the air conditioning, if they turn on at high speed.

[@dannysdiygarage]

I don’t have that answer

Hi.. Thanks for video.. My car Honda Fit 2017 Fan High Speed Running about 96c.. Fan Low Speed Running with ac on only..its normal?

[@NELSONG12]

Great info. Gracias!

[@dannysdiygarage]

You’re welcome, appreciate you

[@aakudev]

I have an 8th gen Civic, the temp gauge stays in middle, but when I open the hood it feels very hot. Is it normal, or I am just thinking too much, i have flushed and changed my thermo and coolant already

[@dannysdiygarage]

Yeah, probably thinking to much

[@greendirtt]

Got 2008 civic lx. When i start car, the temperature gauge goes all the way up to hot within couple minutes. If i turn off car and restart, temperature gauge goes to the middle. Any ideas?

[@dq3283]

is the radiator fan supposed to start spinning as soon as the car comes on?

[@coffeedollsvp]

What is part number for bottom sensor

[@Jonathan_Destang]

I refilled my reservoir with coolant but still overheating. Fans are running. Do I need to also put coolant directly via the radiator cap?

[@dannysdiygarage]

Yes, when the vehicle is cold

[@AmaraSesay-g8y]

You are great

[@dannysdiygarage]

Appreciate your support

My civic 2010 overheated change radiator cap 19045-paa-a01

[@dannysdiygarage]

Appreciate you sharing this information

[@WilliamDavis-f7j]

2010 honda civic running hot at idle and while driving. Fans only come on with ac switched on. Oil is new and full. Cooling system is full, topped off, and burped. At high temperature overheating without ac fans don't work. Also new temp sensors are new. Please help

[@dannysdiygarage]

Let me do a little research and I’ll get back with you

[@kylekramer1260]

make sure your radiator fan is working when not using ac. issue i'm dealing with currently and trying to figure out.

[@The.khushwinderbrar]

@@dannysdiygarageam finding same issue is there any solution for it .?

[@willfreethemfreethem7671]

The engine was so hot the plastic was burning my hand

[@dannysdiygarage]

Engine temperature can get up to 220 degrees without overheating, plastic could be hot to touch, I suggest getting a scanner that read both coolant sensors, I have links in the description

[@atgn70]

2012 civic..NO heating or cooling codes....Replaced BOTH fans,,BOTH coolant temperature sensors and the thermostat..I also replaced the hvac pressure sensor...fuses and relays working properly....Car still got hot in the drive thru with the red light on,and the fans refused to come on,,this is after everything has been replaced...Later tonight fans came on,,,,work for five seconds or so ,then shut off...Both fans would come on every 30 seconds or so then shut off..When the fans were working,,civic would not overheat...Then sometimes the fans won't come on at all while the car is overheating....It's very inconsistent....I'm at a loss...And all of the parts were brand new..The last thing I put in was the AC condenser fan today...There were times where it was working while car parked running...Fans never stay on for more than five seconds...You have anything for me? lol...I also am having issues with my ac...Car runs great,,I don't want to hurt the motor...In the civics,can a condense issue cause this problem?? I mean,,it's thE ONLY thing I haven't replaced!

[@dannysdiygarage]

Have you watched this video kzbin.info/www/bejne/n2qXc6lugMaJsKMsi=LBkjO7lAS8qy1hbd

[@atgn70]

@@dannysdiygarage I watched the video...I don't believe it spoke of what I'm dealing with as far as the inconsistency....Can a bad condensor cause fans not to come on when car is overheating?

[@dannysdiygarage]

Short answer no, send me an email with your phone number I’ll call you and try to help, but only if you’re in the USA

[@atgn70]

@dannysdiygarage Hi Danny. Email sent last night.

[@dannysdiygarage]

@@atgn70 are you ready to talk

[@willfreethemfreethem7671]

Hi again my Honda Civic is overheating without showing signs of overheating

[@dannysdiygarage]

That doesn’t make sense

[@willfreethemfreethem7671]

The gauges said that it was fine but even my spark plug covers were hot to touch

[@dannysdiygarage]

@@willfreethemfreethem7671 if you want peace of mind and want to be 100% sure, buy this: amzn.to/3H3yrkg this will check both coolant sensors and you can be sure there is no air pockets, also check your level 👍🏼

[@dannysdiygarage]

@@willfreethemfreethem7671 I'm working on a video that should be out next week that might help you with this issue
