Aries Cheng: yah,,,my oil change guy needs a really good complain

MrUrenov: Hi there, my problem is on a 2002 civic ex overheated when I got to traffic bumper to bumper after driving at freeway speed . Temperature went all the way up, checked the coolant in reservoir was full but not hot, radiator was low in coolant but I'm wondering why the coolant from reservoir didn't transfer to the radiator 

Declan Meaney: hi,I have an overheating problem, my car has had a new fan a new thermostat no leaks externally and I am not losing any coolant, also my heaters are blowing cold..... takes about half hr of the engine running from cold to run up to the red..... I am not driving it this happens just sitting on my drive...please help?????

Jong Nicol: hello all, i'm having heater trouble about my Pontiac Montana. I tried to drive this Montana van for about 30minutes up to an hour and even more just to reach the normal operating temperature.. I observed the temperature gauge it reached the normal operating temperature but STILL NO HOT AIR is coming out both in front and rear vents (always cold air). The heater and fan control knob is pointed to high already. No engine overheat temperature, I checked the radiator fan it runs well when required. The radiator coolant level is okay and the overflow tank as well. I already did coolant bleeding or burping several times but still no hot air. Your help or any suggestions is highly appreciated.

Frankie Soto: My problem is the following which is I have no leaks !, although i replaced the radiator but every two days i'm adding coolant to the radiator and it's just evaperating. I plan to change the hoses and also i noticed that the presure gage is not installed. HELP !!!

Christopher Pausz: You explain these things very well. Thanks for the info

Paolo Panetta: very helpful information, thanks

Indo Lanka: My car overheated (running with a/c and lights on after driving about 100km's) and cut off the engine on the freeway. Now the engine light comes on and cannot drive it for more than 10 min and heats up like a hell. Any advice with out finding the codes or is there any way of finding trouble codes manually on this vehicle. Searched everywhere could not find for this vehicle. 

soundspur: Thanks for video which helps. Trying to first time diagnose my overheating 99 Civic Can’t make a wrong diagnosis as were in mid-winter,& I’m not all that capable. I have tools but no pressure testers etc Symptoms: No heating inside car:.Radiator fan never kicks in. After topping right up, radiator coolant leaks out for a minute or so then stops. From cold Temp gauge hits the red in about 6 minutes. So I do short trips as I need to! H/Gasket seems OK and no oil & water mixed. Gut feeling is it's the radiator and I should change it! Or could something else -thermostat have triggered or contributed? Can 1 problem trigger another? 

Savannah Soto: hi i have a 2000 chevy impala my car would over heat after 8 or 10 mins of driving it it would go all the way to the red part and start to shake and make shaking noise..my steering wheel and dashboard area would shake and than the car would start to go slow like 20 miles no matter how hard i press the gas than the meter would go back up and the car would be fine and drive normal speed and than go back down red and do the same thing ...... do you think u might know the problem??

YOURmainCHANNEL: Have a Integra blows hot air then goes cold/heater .. also hoes to over heat by then goes back down. My upper hose is hot but lower hose cold/radiator... 260k change thermostat and radiator plus coolant Neva change the water pump car was used but iguess those symptoms of a bad water pump????

blacktai28: I have a 1995 caddy sadan deVille telling me engine coolant hot idol engine and it's constantly getting hot any tips on how to fix this Thanks

North Perth Mechanics: If symptoms occur, don't hesitate to go to your nearest car repair shop to avoid accident. Thanks for the tips. Good job!

Shane Blandford-Scherr: My sister drives a 1985 Toyota tercel and the guage rises up to just unnder the H on and off the red line, the single electric fan works and the raddiator is full/doesn't leak it is the factory radiator and hoses though not sure if that changes things have any idea what's wrong? Also I took out the thermostat completely for a day then re installed it and so no difference without it, thanks 

Chas onay: Hi! I warmed my car up for about 20 to 30 minutes on a Monday below 0 degree weather (Chicago). Soon after, the gauge on the dashboard starts to rise near the H with cold air blowing out of the vents instead of heat. The coolant in the reservoir is kind of slushy due to the freezing weather still. Can this be a thermostat gone bad (thermostat stuck closed)? Mind you, i just replaced a thermostat a month ago. I also blew a head gasket afterwards and gotten all of that repaired two weeks ago. My second question is was my mechanic suppose to change the thermostat as well after installing a new head and head gaskets? Now Sunday before the overheating occurred, my car was operating normally, a lot of heat blowing and the gauge (car) is at the normal temperature. I can;t afford another head and head gasket, so i did not move my car by any means. Please help me!!!!!!!!

Allan A: awesome great help thanks

AMOS MOSES: QUESTION.....if i take off a radiator hose and then start the car (92 bmw)... shouldnt the water come out at a high velocity??? ...trying to determine if water pump has stopped working???????

william kwak: new car, burning smell when driving at 4000 rmps, what do you think is the problem? madza cx-5 grand touring AWD

Gul Bax: That is very helpful thank you ...I have a 2007 Komatsu 3 ton Forklift Engine that used to Steam overheat , Opened the engine changed The Pistons ,bushes & gaskets now after a week the same problem again , though we have checked all the water lines and hoses no leaks in or out ! What you think ?

Shaundrika Shinn: Hello, I have a 2000 maxima the temp gauge was going up as if it was overheating but no smoke at all. The thermostat and water pump was just replaced but the gauge still goes up while driving and it goes back n forth from up to down. Do u know what could be the problem

mark Loria: Hello sir.. Question: i just get into overheat engine and my check engine light is on. After few minutse I check my oil dipstic and my oil was very low. After adding oil in my car engine and try to drive it around I noticed that my check engine light is still on.. what is might be the caused why is my check engine light is still on? Thank u for the responds 

Norlistapes7: Hey Trust i got a question,my 2000 Chevy Impala overheats,i have had the coolant switch,radiator and thermostat replaced and there are no air bubbles running through the system and i've ruled out the head gasket as there is no leak in the block the car runs better but the temp still climbs when i'm idled and the low coolant sign comes on periodically what's wrong? Oh, only one fan works on my duel system..

Danny S: I have a kia sedona 2004. Radiator hose blew out on a highway then it overheated the engine. Engine doesn't start any more does it mean I have to change the engine or is the a chance to save it nay be there is a part to replace.

Vijay Chandrashekar: Wonderful guidance. thank you so much. appreciate it sir. i detected myself that i have a water pump leak which is causing the overheating now. thank you so much

enrique mora: my truck is over heating on freeway

TariQ Alaa: I have a 84' Mercedes 190E and i was just wondering at which temperature should i start to worry about overheating? When the car is idled in traffic it reaches up to 100C , Other than that its mostly at 80 or slightly below or up. Should i be worried?

7SickoZ: Have a question if someone can help me with, Is the Hose running from the engine to the collant reservior supposed to have fluid in it when the car is off and engine is cold? 

allsaw31: 06 Chevy equinox has an overheating problem. Mechanic replaced the radiator but now says that car had a blown head gasket. Coolant/water still leaks from the overflow hose and no heat in car.

DION BROWN: HELLO... have a question Monday my car was over heating put antifreeze in it the antifreeze start to boil so I waited until the next day to drive my car... drove it to the oil place to see why the antifreeze was boiling... the man told me to get it flush but he didn't wanna do that cause he said something about moist being in my oil so when he pop the hood something was steaming and leaking the man said it had to be antifreeze took it to the shop... the man said that it was my y pipe it had burst do to rust... Do have to take the trans out to replace the pipe that was what I was... doesn't sound right to me.... have Suzuki Forenza 04 and also my car was blewing out white smoke from the tailpipe... he said its not a head gasket could a y pipe cause a car to over heat and make the antifreeze boil 

Marquise Callaway: I have a 99 Nissan Maxima, I really don't know much about cars but recently my car has been overheating so I thought I just needed antifreeze but I have to add antifreeze almost every week and it still over heats I think there's a leak in the radiator I also found a hole in the radiator I have now on the upper plastic that smoke comes out of which I think helps the car overheat as well. Please help. 

Murad Sen: Hi, I have a '02 Jetta. It started to overheat , it usually happens when i am driving on freeway and it also happens after some time when i am driving on regular road. The radiator hose gets hot so i think that it is not a water pump problem but motor still feels cool when the gauge needle starts to go over 190.Can be the head gasket ?

ferne wilkinson: I have a 2002 jeep cheeroke that overheated. And put antifreeze back into it and still overheard and put antifreeze bfn into over flow jug what should I do help pleasand there is no antifreeze in my oil and still overheating

Brooke S.: Question:[04 Monte Carlo] I have replaced my thermostat (& the housing), the intake gaskets, and bled the coolant system several times and my car is still overheating and the heat is not working. Everytime it overheats the antifreeze is full (no leak anywhere).. could it possibly be the water pump?

Israel Perez: Question. My car gets to 3/4 hot ONLY when going uphill. I can push the hard as hard as I want either on the freeway or the road. I don't get why it would do that? The temp stays right below the middle mark. Also i don't know if this is relevant, in cold mornings it has low idle. And when it hot it goes away. 95 eclipse Gst . Thank you

phrozen17: First of all I think it's awesome that you actually respond to peoples question on youtube. My cabin heat randomly turns off and immediately the temp starts to skyrocket, often the heat will then randomly start again and the temp will drop back to normal range. It once overheated into the red, when I looked under the hood, all the rad fluid was in the overflow tank. I took off the cap, it flowed back into the rad. I changed the rad cap, wasn't that. Also the temp gauge is jumping around as it begins to overheat and then returns to normal. Any ideas?

YOURmainCHANNEL: Thanx alot for your reply sir... I hope is not the water pump got a $550 quote without them even looking at it & if its just air bubble? Stopping the flow then it should be a easy fix correct?.. and by the way I haved topped the radiator and had to refill the reservoir since it kept going emty/weird... Hope there's no leak around the pump causing it...that's my thoughs... Never had to experience this its new to me.. 

shelsi morse: Hi I have '99 ford Taurus and am wondering why my engine is knocking and coolant is leaking

Neal Stevens: HI, about 2 months ago my temp gauge would read that my car was overheating and I had to replace the coolant temperature sensor. This fixed my problem but today my car overheated and I had to add coolant. After I added the coolant it didnt leak out but was bubbling in the reservoir. Any insight what could be causing this? I haven't tried to drive it after this happened but I'm sure there is something that needs to be fixed and wondering where to look. Thanks in advance!

Amouzou Smith: Hi my car is overheating I added a cooling but it can't stayed for 5 minute and I don't see any cooling on the ground, what is that problem thank you

fash9120: where do you get a cooling system pressure test?

TrustMyMechanic.com: More than welcome. If you think you have a coolant leak then you need a Cooling System Pressure Tester. A compression tester is used on the engine to determine if there is internal wear/damage.

westin1985: These new cars have electric fans. Are those fans able to pull enough air across the radiator to easily cool the vehicle at idle and slow speeds in hot weather. I get they use electric fans to make the car more fuel efficient. Don't they allow the car to easily overheat. The fan in your truck pulls a lot more air than those electrics fans do and should easily cool the engine.

Paul O'Neal: A bunch of the fins on the radiator are bent. I just noticed it overheating yesterday when I took it to a city with lots of traffic lights. The fans are operating fine. I just replaced the thermostat and it did nothing. I will be replacing the radiator in a few days.

TrustMyMechanic.com: You want to get a cooling system PRESSURE Test to help locate a leak, if you have one. A compression test will help you determine if there is internal wear inside the cylinders, which I dont think is your issue. You should be able to get an aftermarket radiator for about $150-200 or you might see if you have a radiator shop in your area that can "boil out" yours, sometimes its better to get a new one than try and mess with your old one though.

TrustMyMechanic.com: As long as there are NO coolant leaks and you are not constantly adding coolant to the system I would lean toward a problem with the radiator...a restriction at the bottom that can not be flushed out. When its running hot, feel the upper and lower radiator hoses, they should be pretty close to same temp. If not, there is air in the system that needs to be bled out, there is a leak and not enough coolant, or a restriction is happening. Does that help? Probably not an issue with the fan clutch.

TrustMyMechanic.com: I would first start with cleaning the throttle body, I have a video showing you how to do that in my youtube channel (sorry I can't put a URL in the comment here) try that first and see what happens.

TrustMyMechanic.com: Those vehicle are notorious for small headgasket seeps, but if the engine is not overheating and you are not having to continually add coolant I would not worry to much about it. I do have a really good headgasket sealer additive I show in my youtube channel....."best headgaket sealer" you might want to try it and see if it helps.

Omar Chisolm: did u bleed the cooing system? anytime u open the cooing system u allow air inside which can cause overheating, and lack of heat in the winter.

westin1985: What is the maximum air temperature a typical vehicle can endure with out overheating with the AC and blower running? Do they put out these statistics/information on cars?
