    don’t know if you solved your pblm: most likely a hose is leaking, tell them to pressure check the cooling system..but curious why you say fluid finishes…can’t really know well if you are losing coolant unless you check it before on a cold engine. also, you would know since your car overheats…(the gauge by the speedometer would show the temperature of the engine rising.. if that is happening, defintely have it looked over..

    You can dump it in my neighbor’s yard.

    But you should actually take it to a recycler. Any quick lube center should take it for you free.

    thats not proper dumbass. you have to take out the thermostat because the cold water from your garden hose will not allow the thermostat to open, also its best to open the drain valve on the bottom of the radiator before you flush it that way, because the rust and sediments rest at the bottom this has to be done a couple of times. and lose the beenie you look like fag, i have no tollerance for faggotry

    Great how to! I just have one question, what do you do with the water that comes through the system? Do you have to take it to someone special or just dump it in your neighbors yard? :)

    Please help me. Thanks in advance.
    (Note: I have no chance to take my car to another service because of its motor guarntee)

  14. cypriotlion says:

    Hello, I drive a 2006 mini cooper and coolant fluid finishes continuously. I have to refill it everyday. Car service changed the radiator tap. But the problem could not be solved. I took my car service twice and they could not get rid of the problem. I saw water under the reservoir but I am very bad at understanding car mechanics since i am a girl :(
    Do you think that I need to flush engine coolant? guarantee)

  15. monaLMAO says:

    1. Steve89z is right, unless you removed the thermostat b4 doing this.

    2. Isn’t the water pump pumping with the engine on and going against the flow?

    i was gonna say the same thing

    the way he talks is so annoying

  19. Brockie777 says:

    Thank you. You service a cooling system properly! Most idiots just drain old coolant without properly flushing the old stuff properly, thus causing a chemical reaction. You rock!

    is that a ford ranger you are working on?

  21. steve89z says:

    you don’t want any tap water in the system at all.1.drain radiator and block,2. add distiiled water through the expansion tank,close drain,start engine,put heat on,let it reach normal temp,then drain,let cool then add 50/50 coolant.use distilled water throughout.i use the 5 year universal stuff.

  22. steve89z says:

    the thermostat does not open with cold water running through it! only opens when operating temp is reached.
