Matthew Rainey: Good video thanks for the knowledge 

Joel N: I watch your video nice video explanatory,I am mechanic but but when it comes to check for plugged or flow problem I am not that good or have the right Techniques , I will give you an example I have one customer that calls me because his vehicle is being over heating he told me he already replace the thermostat and radiator cap, when I get to the vehicle I checked for cooling fan operation and they came on on time according to temperature, he told me is been loosing coolant so I pressure tested the system and no leaks external and holds pressure, next test I did is block tester fluid , fluid never change and temperature at idle was very high fans on, and a lot of pressure coming out from radiator cap , vapor and trowing out coolant still did not change color of block tester fluid, I touch upper and lower radiator hoses and both were hot and pressurized. I am suspecting of radiator flowing or plugged, the front of radiator fins are clear, how do you test for plugged or flow problem I have a temp gun but the front is cover with condenser and the other side with coolant fans , would you give me some tips how test radiators on vehicles please, thank you for sharing.

Chitab Koret: YOU ARE ALWAYS RIGHT #TrustMymechanic.i believe you and TRUST YOU!! I took my radiator for thorough check and cleaning.i thought my Daihatsu Feroza is dead but believe me NO MORE OVERHEATING,i felt the radiator cap it was cold as if in a refrigerator,not like before,it was so hot you wont attempt to feel it! Hey man,welcome to Kenya i give you a ride to Masai mara national park!

Ronald Jones: I have a problem. . When Im driving, my car runs cool. When I slew down or stop at a light it starts to get hot. As soon as I'm rolling again it starts to cool. What can that be? ? I put a brand new thing of coolant, put a new radiator, and still get the same problem

Mike Cameramike: I am in Costa Rica - hot here all the time. No water in oil - no oil in water. Have changed and removed thermostat. I do need add antifreeze after 1-1.5 hours highway driving about 10 oz. Replaced cap. Suspect head gasket but no test fails. Replaced upper rad hose was weak. The metal pipe that the upper rad hose is badly rusted. Could my radiator be plugged - is there a good test for this? Fans operate wired them with manual control for a while - is wired back to normal now. Did HC test and it passes. Do not want to take to dealer - is last resort. Here is a video of cooling system pressure test. http://youtu.be/wHKXCcyItrI

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 !!!

Paolo Panetta: very helpful information, thanks

Vonetta Cousins: Ok , when was driving yesterday . My car was runing hot . But , when I pick up speed it cool off . I had the hole change last year . And when I park the car it leak little antifreeze . I have 2004 grand pix . 

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.

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????

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? 

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!

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

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. 

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!!!!!!!!

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???????

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??

lindytown: Great video, Very informative. Thank you!

Heather Sickmiller: We have a 93 corolla and we drove it on a freeway when it over heated and added radiator fluid with no visible leaks. we attempted to get it somewhere lit(it was night) and it kept overheating as soon as we accelerated. A hose came off and we stopped and towed it from that point. My question is where do we connect the hose back to troubleshoot whats going on with the car?

Gurdev Singh: hi, i just filled water in radiator tank 2 days ago, today water was damm boiling from radiator water tank. i just released cap and water start leaking from cap. i couldn;t even touch the cap it was very hot. what could be the reason? i just filled water, do i need to mix coolant as well or it is optional? plz help

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

Justin Cooper: I'm from Michigan and it is cooler now and it's nice to have the heat on. I was driving down the expressway the other and the car started to overheat while at the same time I lost heat to the cabin. I have had no problems with leaks and do not see any leaks where I park. I do notice, however, that now my antifreeze reservoir is over its "hot" mark, even when cool. If I drive around town, it over heats and I lose heat to the cabin, and then the indicator returns to normal and I regain heat to the cabin. Furthermore, I'm not seeing the electric fans kick on to cool. Any help would be much appreciated! Justin '95 Lumina 3.1

dave willis: 05 sebring lx 4 cylider looses water but i cant seem to find where its going no water in the oil and none in the transmission. it dont get hot never has the only reason we knew it was low on coolant was the heat quit working one morning but would work when she stepped down on the gas. now ive been driving this car i havnt had an issue but i havnt been driving 100 miles a day either maybe 25. nothing has ever been done to this car ever regularly maintained is all. if this is a water pump isnt this attached to the timing belt at just over 150000 debating on even keeping this just because of a cost that should be minimal.

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?

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 

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? 

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..

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?????

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.

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.. 

levi knox: On my 98 oldsmobile cutlass keeps overheating changed water pump t stat no white foam in oil keep loosing colant out of the over flow any suggestions 

caleb tetloff: my dad was driving up a hill and the car stopped and overheated we open the radiator and it sounded like a teapot and steam shot out of it. we we had jut gotten off the high way. we put water in it and noticed it did not have coolant in it so if we put coolant in it will it stop over heating?

Martin Corleone: i dont pickle around, i replace hoses,water pump,thermostat, flush, everthing the cost of this is nothing compared to a new engine and install, my thermostat was stuck open, also the water pump should be mentioned

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

Jairo Razo: Houston :D

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

Atuomobile C a t: my 08 nissan titan have a belt driven fan & an electric fan as well.

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 

Allan A: awesome great help thanks

Muhammad Bello Garba: What a nice video, a lot of thanks! 

Cory Sanfilippo: Hey there, so I have a 79 BMW with the inline six 528i . I live in Arizona and its hot. I just bought the vehicle and replaced the water pump and got rid of the thermostat. I did a radiator flush and cleaning. I filled back up and did the regular all around service, oil, tranny brakes. She I start the car. There is smoke emitting from the exhaust manifold instantly but doesn't have a rattle like its lose? And suggestions. Also. When I start it. Within two minutes my coolant is just bubbling in my reservoir and really hot. Do you have any idea what could be wrong? Thank you very much. 

Mark Snodgrass: 2000 s10 overheated and quit and hasnt cranked since,checked forir fire and its getn fuel,oil isnt milky,not sure what to do next

Mario s: I own a 2005 Ford Freestar 4.2L I've been having overheating issues for weeks only on the freeway, flactuating temperature. I replaced my thermostat, flushed out entire cooling system, replaced with 50/50 premix. My van still overheats only on the freeway, keeps flactuating from just under 1/2 to over 3/4 on temperature gauge every 5 minutes. In the city stays under 1/2 on gauge and has very good heat without overheating. Also top radiator hose is hot but the bottom hose is only lukewarm. Overflow tank is to proper fill line. Just prior to the stat instal, I dumped all the antifreeze, removed the old stat and ran the van for 3 days. Temp stayed on cold all the time, freeway & city. Do you think my radiator is partialy pluged? Why would it be cold without overheating without stat in place?

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. 

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.

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?
