    Excellent information... I'm currently experiencing my fans taking quite a while to turn on when im warming up or idling on my CR-V 2nd Gen. I will check my thermostat.

      It could be normal fans do take a while to turn on as long as it dosent over heat they only operate at certain temperature

    My heater works, Ac works, my upper radiator hoses gets hot on time, but my bottom radiator hose satays same not hot, but when I drive my car and hit the gas over 30 mph, my temperature gauge says car overheating, I watched your 2009 mazda water outlet video big leak, and did it step by step, and no leaks, but my cars says over heating, and I also checked the bottomed radiator hose without turning my car off after it says overheating, that hoes I’m not even hot what’s the problem here sir? And I thought there was air stuck in my coolant system, but I blurb it, so please help what’s the issue? Could it be the coolant sensor cause it came with the cheap water outlet.

    Hi, What if the upper radiator hose gets instantly hot along with engine, but bottom hose remains relatively cold. Plenty of heat inside cabin. If I turn off cabin heat, engine starts overheating while driving on highway.

    • @RBTheMechanic
      @RBTheMechanic  Před 6 měsíci

      Lower hose I think suppose to be cooler cuz it goes through radiator to cool off depends where thermostat is

    Hello im in a dire situation and i have a question, my car started off blowing cold air from the AC if we would turn the AC on in the winter then a few months later it started overheating and reaching the red line and running out of battery in the winter. We replaced the battery but its still overheating and today it was overheated without driving it in a day.
    Please respond as soon as possible 🙏🏾 thank you.

    Can a bad thermostat keep antifreeze from flowing to your heater core? Also can a heater core that needs flushing out cause a person to think that the heater core has to be replaced, that it is no good at all when only the flush out is needed?

      I can replace my thermostat myself. Easy to get to. And after the engine is cooled off overnight.
      Just common sense. Can drain my coolant but DONT think it's 100% necessary

    We did a heater core flush and the heat still isn’t working but the car heats up fine in the dash still possible it’s thermostat? Both heater core hoses don’t get warm unless driving and then the heat works inside as well.

      If only a flush out is needed for the radiator plus the heater core, and that's the problem, could a person automatically assume (mistakenly)
      that he or she has a bad heater core and it must be replaced?
      May not necessarily be bad, just clogged.
