Good stuff Jabo, I seviced the same vehicle. It was overheating while stop and go driving. Pin point the issue to autozone coolant temperature sensor, replaced it with an oem and problem solved, easy pay day.

Bro it definitely helped me out 🙏 got a 2014 civic with 130k starting to overheating only on idle (in a drive through for ex) and ive been told about those water pump problems. Gonna run through the text u did right away

[@ikzuq]

Bro did u manage to fix it or anything? I get the the H flashing once i idle for like 10-15 mins and never when i drive, help plz 😢

[@abcdefggg5658]

@iKzuq it was the thermostat! Got one for like 20$ and replaced it along with all the coolant and flushed the air pockets out the system and its been perfect simce👌

​@alexcruz5658 yup i have a 2003 civic lx same thing happen to been and once I replace the thermostat it's been fine since

[@bruceang82]

Thanks Jabo , I was wondering about my water pump functioning properly , it seems to be, when the fans finally kicked on the air was hot. still haven't figured out why its dumping the coolant in the overflow , i drive a 100 mile a day & am adding about 1/2 pint in it a day, runs fine otherwise, no oil in coolant...no coolant in oil 345K miles & I've had it since near new & have always taken care of it . i get little trickles of air bubbles in full coolant tank. I super flushed the entire coolant system ,radiator, heater & engine block all separately , ran 150 miles with thermostat removed & radiator flush fluid in system, flushed again & put all back together & refilled with proper coolant & purged...still the same.

[@JaboTheMechanic]

What other things did you check did you check the radiator cap that could cause it to purge out did you check compression in each cylinder to make sure that the compressions not low you might have a blown head gasket or you could have a bad water pump from improper flow that would cost it to build-up pressure over heat and overflow into the over flow tank

But what I found out is that my car do go over the half mark by the heat gadge when I put on the heater on in the car. Thanks and plz if u can maybe help me with this.

Hey Jabo we just had the head gasket, water pump and timing belt done about a month ago on my son's car and now it's pumping water out the resevior. Before taking it back to the mechanic that did the work we changed the thermostat, radiator cap and radiator. So having that issue. His fans do engage so they're good. Is it possible that he's gasket messed up that soon or the water pump?

I've had this vehicle for over 10 years and realized I'm better off connecting fans direct. I made a switch on the section next to cigarette lighter. These cars are notorious after stop and go driving to creep up in temp.

[@jessicachapados6280]

I have a '05 civic with 186,000kms. (Live in Canada) I've only had it for 4 months now and had MANY overheating issues since! I've replaced rad, hoses, thermostat (OEM), sensor on thermostat housing, and bled the system many times. It didn't over heat for about a month after all that was replaced, but then it overheated AGAIN last week. I saw my fans weren't kicking on so I checked and found a bad fuse. Replaced it which fixed the fan problem, but when it overheats it pukes coolant everywhere from the overflow tank.... Now I'm having the popular problem where it sometimes blows hot air when I'm driving (sometimes just cool air), and cool air when I'm stopped/idling... I don't want to load the parts cannon anymore but I'm aiming toward waterpump (I'm told after 180,000kms it should be done) but I don't know. I'm just tired of thinking I've fixed it and then BAM I'm back to square one. PLEASE give me an idea of where to go with this...either rad cap, water pump or head gasket?? PS. Would not puting the OEM coolant in, be an issue? I'm asking cuz I was told these cars only run properly with OEM stuff..?

My civic isn’t overheating (the radiator cooling fan is coming on as normal) but the coolant overflow bottle is always full but when I check the coolant level in the radiator it more low then other times, is this normal? Is the overflow bottle and the radiator both always supposed to be full? (My mechanic says it’s not a head gasket problem)

[@michaelg6641]

I think the radiator cap can definitely be an issue as my coolant was simply disappearing and gauge would go way up but never actually overheated, so I changed mine twice, and the second one I noticed had a real firm seal as I screwed it on and topped up the coolant with the 5050. I got the more expensive $10 cap instead of the cheaper one at ORileys.

[@nmot97]

Did it solved the problem?

[@michaelg6641]

@@nmot97 Seemed like it did, but now its getting warmer out and gauge already went higher as I was sitting at a drive through the other day. I bought a new Honda thermostat on line that Ill have put on next. Actually last summer it got so hot it went into limp mode, which I didn't know civic had that, (but it was driving it hard though) and it barely ran until I got home. But it recovered next day and been fine since, after I checked oil and r. fluid. Somehow if I forget to llook for a week or 3, the fluid will disappear, both times in Arizona and Nevada, where its super hot in summer like 90 - 100 all day long.

Will not burping it cause overheating? If you don't have a reservoir cap will that cause overheating? How can I check for vacuum leaks?

Yo Jabo, I’m having overheating issues , when idle, I don’t over heat when I drive . I replaced the thermostat, radiator cap and bleed out air. Don’t think it’s the coolant temp sensor or allowing the fans to kick on fast enough ? I have a 2009 Honda civic ex 1.8l

[@SummerEaze]

I'm trying to diagnose the issue on an 03 Civic. Car was losing power while driving no matter how hard I gassed it. Both brake & gas pedals felt stuck. Needles would all go down near zero. While parking, I couldn't even reverse the car as engine was not responding to the gas pedal. It worked after letting car sit to cool down. But within minutes of driving, started to lose power & overheat. (Needle doesn't point to H) Made it home just in time as I was seeing white smoke coming up the passenger side of the engine. -Fans blow fine. -AC & heater blows fine. -Did not see any coolant leakages. -Car battery is new. -No electrical issues though. Car starts up strong everytime & gears shift without a problem. First thing I will do is replace the air filter. It was dirty. I assume there's a clog somewhere & hopefully no additional issues. Any ideas what it could be? Thanks for the vid too it was a great general diagnostics for overheating issues.

[@lidiagarcia8512]

Is over heating a probable cause of a blown head gasket? Also I rode around with my hood off while overheating & it splashed coolant all over my windshield, thought I blew a coolant line but it all seems in tack.... I would genuinely appreciate any advice thank you!

[@emangee9268]

A blown head gasket can be causing your vehicle to over heat, best way to know if you've got a blown head gasket is by checking your engine oil. If your engine oil does not look clean and it looks milky, then you've got your engine oil mixing with the coolant. The cylinder head gasket would need to be replaced and the cylinder head should be pressure tested and worked on by a machine shop.

My mom's 01 Honda Civic is overheating after I changed the thermostat gasket , and I changed the lower radiator hose... Only on long trips or when I push it on the highway. I also changed the radiator fan and coolant temperature sensor. For some reason it makes thr coolant in the reservoir over fill...

My car was doing this for a while, but only just recently has it been overheating even while driving. I can smell the coolant burning and when I open the hood I can see there's some mild leakage with steam, but never anything under the car after it's been sitting. Car has no AC (didn't come with it), but the heat/defrost has been working fine. Not looking to pour a ton of time and money into the car if I don't have to (I'll just sell it), though if it's an easier/cheaper fix, I'll probably do it.

[@Papaijanos]

D16V1 cooling problem is known! The point is that the expansion tank should be filled to the maximum level when the engine is warm, and the radiator should be filled to the maximum level as well. If there is still air in the system, the car should be parked on a sloping driveway with the front facing upwards. With a warm engine, idle the car and turn the heat to maximum and set the internal air circulation to on. Remove the radiator cap and wait until all the air comes out through the radiator. When no more air is visible coming out of the radiator, the engine speed can be increased to 1500-2000 rpm. This further circulates the water and more air will come out of the system at this point. As air comes out of the system, the radiator should be continuously refilled. After this process, there should be no more problems. Every mechanic told me that my car had a blown head gasket, this was 6 years ago, and there has been no problem to this day! I hope I was able to help...

[@neuro82h]

Hi! After that procedure, did you set the reservoir tank between the min-max level? Or how did you mean max. level, fill it up completely or just up to the maximum indication on the reservoir? I also have a problem that looks like a head gasket failure, however, there is no coolant in the oil and no oil in the coolant, also no exhaust gas in the coolant. Only a symptom, which is, the coolant level always goes up in the reservoir (until it fills it up completely eventually) and gets lower in the radiator. But does not disappear from the system, only moves from here to there, if I fill it back to the radiator, it looks good again. Perhaps this is only an issue of an improper coolant change, air bubbles can be in the system? Happens after I was at a mechanic who turned out doesn't really do Hondas, or japanese cars at all.

Also after leaving the engine on and running in parked, after about 20 mins, it starts to heat up but not as fast as when I am driving. I took it to a shop and they told me that the bigger fan is not a original part it is a universal fan n therefore the big fan is not performing what it is suppose to and it’s causing the smaller fan to over work n may possibly be y the car overheats. Is this correct? Because the big fan works, but yes it is not the original part.

If your civic is overheating (especially after running it at highway speeds), and you keep on having coolant getting pushed out of your reservoir, its very likely you have a blown headgasket causing exhaust gases to enter your cooling system and push out the coolant with enough pressure (for me its about 15 minutes of highway driving and then if I stop at a light off the highway I will overheat because I have no more coolant in the car).

If the head gasket was blown the heat wouldnt fluctuate tho. It would just continue to rise

I have a 05 civic can’t figure it out please some advice lol my car overheating only blows hot air while driving it gets cold when I stop at a light... seems like radiator gets dry and overflow fills up but doesn’t return to radiator.. have changed radiator, thermostat, checked all hoses can’t figure it out..

[@LUIBEFISHIN]

Also fans seem to be operating fine..

[@JaboTheMechanic]

It could be a faulty water pump

[@LUIBEFISHIN]

I’m a try a flush tomorrow just too see if it helps but I honestly think it’s the water pump too ... is there any way to rule out head gaskets ? Btw thanks for the advice

[@JaboTheMechanic]

If it's the head gasket you could have a quick rough idle during cold start up. And it would immediately overheat during driving or idling

[@LUIBEFISHIN]

It has done that a few times lately but hasn’t overheated I drive it to n from work lk 20 min each trip ..I think it’s the water pump .. I did a test spark plug by spark plug witch I changed as well just cause I was removing them .. and cranked it w one spark plug in at a time to see if radiator would bubble or shoot water out but nothing happened..also tried taking all the air out w a spill proof funnel but car wouldn’t stop giving air bubbles had it on for about 40-60 min

I just bought an 03 civic. I noticed the temp gauge will go up to H and right back down to normal and kinda bounce around a little. Had it 2 days doing that. This morning was chilly so I had the heater on and was working fine. All of a sudden the heater stopped, temp went up, and check engine started flashing. It over heated and cut off and I pushed it to nearest gas station. I know both my fans work. Has a new radiator supposedly. Any idea on what it can be?

If you’ve done anything with the radiator you might need to “burp” it. Meaning. There’s still air inside

Hey man. So my civic recently started over heating at first I noticed the heat wasn’t working until I started driving around 40 mph. I changed the radiator and it stopped over heating for like 2 days. (Heat only worked while driving). It hit the the top when I was in a drive through so I had to pull over and checked. And the fans stopped working. Now I’m starting to think it’s either the thermostat, fans, water pump. Any advice or anything?

Sounds like either your fan switch is bad or the fans could also be the relays for the fans

My 2004 Honda Civic started overheating. I changed the coolant temperature sensor, fan switch sensor, new thermostat, new radiator, and new radiator cap. I don't know what the problem is now. Clearly not the head gasket because I took out the spark plugs and pressure tested while the spark plugs were off and no sign of pressure drop. Any suggestions?

[@Nellyyyyyyyy]

I believe you did a compression test if you removed your spark plug. doesn’t really tell you if your head gasket is bad, usually tests your the Piston rings and valve seal. If you want to test your head gasket you would have to pressure test it on the radiator cap. A good indicator to see if your head gasket is bad is if it overheats on long drives, and coolant spills over reservoir. On these Hondas

[@drippingwax]

@@Nellyyyyyyyy You can also use an exhaust gas tester to see if the exhaust is leaking into your cooling system. That is how I diagnosed a blown head gasket in my 2000 Civic.

I had the same issue on my 2004 Honda Civic. It was the fans for me.

[@pmexplore]

@abdul fitt replaced the fans and the issue was gone for about 4 weeks. Then the top radiator hose collapsed. So that tells me there is a vaccum issue. And a pressure issue. I replaced the radiator cap. And so far the issue seems to be gone. I think I will have to do another coolant flush soon and also change the water pump.

Thank you sir, but I have 2 questions: - How would I know if a car is overheating if the thermostat sensor is out and is giving me a false reading? - If the lower hose is cold and the upper one is hot that means the thermostat sensor is out right?

[@elitrevolution1812]

2nd statement is true

[@libragal1750]

My car overheats and coolant starts squirting out all over my hood and windshield after driving it for a bit. Especially after I go uphill. Just had the water pump, radiator cap and thermostat replaced. I found a slight crack in the radiator and that's where the coolant is squirting from. Went today and purchased a new radiator but here's the weird part....prior to seeing the crack in the radiator my hose that goes to the overflow kept popping off and antifreeze was squirting from it and my radiator cap is stays cold even after long trips. Everyone I talk to about the radiator cap says they've never heard of that before. Do you know what the issue may be with my car in general? Thanks

[@libragal1750]

One more thing I forgot to add was issues first started happening a few months ago when I was using my air conditioner. Tons of steam started shooting out from under my hood. Guy at garage changed the water pump and timing belt. Got the car back and one one I used my defroster and I had the same issue,car overheated and steam started shooting out, radiator cap cold to touch. 😕

[@JaboTheMechanic]

If the cap is bad. It will not hold pressure and cause the car to spit out the coolant

@@JaboTheMechanic I replaced the cap. I also just had the radiator and air conditioner compressor changed. It was driving beautifully today then BAM all of a sudden steam starts coming from under my hood. This time it was coming from near the area of my heater core hose. I looked and I could see a puddle of antifreeze near it. Do you know what it might possibly be? I did find one skinny hose with wires on the end that looks like some kind of sensor and it was all corroded. I wish I was able to show you a pic in the comments so maybe you could pin point me in the right direction. I don't know much of anything when it comes to car mechanics 😕
