Been racking my brain for days, checking everything, flushed my whole system ect and ordered a new heater core, going to face the daunting task of changing it..... Just to find out my climate settings had been changed to cold 😅😅 Thank you so much for this video, saved me hours of wasted time 🙌

my heater stopped working all of a sudden, I thought it was the thermostat, $300 later i saw this video, i unplugged the green harness and plugged it back in and it worked, saved me $600 more!!…thank you for the video!!!😅

You’re welcome.. Now send me $300 🙌🏻

Great video. I have a 2015 Mustang, whose heater started randomly blowing cold, hot, nothing. At first, I thought it could be one of the actuators under the dash controlled by the temperature knob or a fuse, etc. Turned out to be a small leak in a radiator hose. This caused the overflow reservoir to empty. The low coolant sensor that monitors the overflow reservoir, then caused my heater to quit working properly. Never thought it would be anything like this. Temp fix is to fill reservoir. Long term fix is to replace hose.

[@maverick_2352]

My ford focus had an airlock which is why it was blowing cold air.Fixed by purging it by holding rpms at 3500 for 30 secs, idle for 30 secs, then turn off for 1 min.Repeat these steps 4 or 5 times till heater blows hot at idle.

[@StigLeivo]

Heater core is in many cars so high vs engine that it's hard to get all the air out. Find the steepest hill and park front up. Give some revs and that's it.

Hello, question, when turning up the heat on that dial, which my dial looks different BMW 525i series, my heating dial was not full. I turned it on full heating but then my cooling is full as well.

[@johnjones607]

Thanks for advising to watch this, however, im pretty sure its none of the issues mentioned in the video, the heater core pipes are both hot, inlet and outlet so i think i can rule that out, it has the right coolant at the right levels, it doesnt have a heater control valve (2009 BMW E92) thermostat has just been replaced as there was an error code for that, system has been bled by mechanic and myself....i've done it at least 20 times since the thermostat was replaced. The actuators/mixers in the dash seem to be working, they certainly move.....i know there's a sensor behind the radio but im sure thats only to do with the climate control, ie, gets to a set temp then keeps it at that temp. Think i may just part ex it against a car with heating pmsl!!!! Freezing out, not fun...i have heated seats but they do nothing to help clear the windscreen or keep me warm. Used car prices are ridiculous, i was looking at buying an X5 but they have just got more and more expensive over the last year, seem to be going up £200 a month or so!

[@startingtech3900]

I’m having the same issue. Just coolant flush new thermostat severs bleeds. Nada just cool air. I think we have fcked heater cores possibly man or they are clogged which could be why the pipes are hot but we’re not warming up.

hey there. i got a problem with my Peugeot 508 1.6L diesel. The radiator fan does not work. I found fan resistor corroded and rusted so changed, thermostat sensor also changed to new still the fan does not work at 90*C temperature. i tried bleeding the coolant near the sensor for air in the system, still no luck. what else could be the issue please..??? the car runs smooth when cold but as soon as the temperature rises to above 50*C, the car starts strangling...??? even when i bypass the thermostat sensor and unplugg it to run the fan in full speed, the car still strangles..?? please help with these 2 issues. thanks.

[@jaankuus3063]

Thermostat opens/closes the "big circuit" which is the engine cooling once it is up to temperature. A thermostat does not affect the car heating because the "small circuit" which is the heating system of the car (it is the same for other machinery. Diggers, trucks, tractors etc.) is always open. That is for winter mostly, so that the car can start defogging the windows before it's up to optimal temperature. You can use even tap water in the cooling system (not recommended) and it should work fine. You might want to change the thermostat when you have to have heating settings on full to stop it overheating.

[@randomoverpopulatedworldid3286]

what if you get heat on one side but not the other.... and sometimes the defrost only works on that side as well... is that the door inside under the dash that isn't opening or closing correctly? we did the water pump/thermo when we bought the car and I watch the coolant temp on my OBD reader phone everyday to see that the coolant temp is getting up to temp. there must be a door under there that's stuck closed???

Europeans drag stuff out for so long things that could be said in America in 10 words you guys take 500 words to say. The reason you don't get heat from your heater is because the heater core is not getting the hot water now how do you get the heater core to receive the hot water is there a valve somewhere that turns on and off I know with the older cars in the summertime you turn that valve off but where is that valve at

[@crnigruja2220]

Best antifreeze/distiled water ratio is 50/50, if you live in areas where temperatures don't fall below -20 degrees celsius, if you using only antifreeze without water, than on very cold temperatures antifreeze became very dense and flow of that dense liquid is slower, which means slower engine cooling, and not only that, 100 % concentrated antifreeze will freeze faster than mixture with water in 50/50 ratio! I'm watched some tests in some series llike "Mythbusters" (i don't remember how it's called) where they tested it in all different ratios, and different temperatures, and best results they get is 100 % concentrated antifreeze with one half of water in it (50/50). I don't know what kind of antifreeze liquid people who live in Siberia using, when temperatures falling below -30 celsius, probably they have some electric heaters in engine space, or they leaving engines running all night (they never turning engines off). But in "normal" temperatures -20 to 50 celsius, 50/50 ratio of water and 100 % antifreeze is best!
