How to SUPER FLUSH your Cars Cooling System

  • Published on: 06 March 2015
  • Learn how to flush your cooling system including the radiator, heater core, and engine block. I go though every step to SUPER FLUSH your cooling system completely. My truck's cooling system was really really bad and it needed a good flush. Now the cooling system is filled with brand new coolant and is clean!

    If your system is old or dirty, that dirt could be clogging holes in hoses, seals, and gaskets so take that into consideration when you do this.

    Black Socket Set I use:
    Hose Clamp Pliers:
    Large Drain Pan:

    You did not use a funnel for adding distilled water to the coolant reservoir?

    great job. Just a general note for anyone with pets, please be very careful around dogs - coolant is toxic. For some reason dogs like the smell and taste - even a small amount of licking it will lead to kidney failure. I have been in a vets office when they tried to save a dog who had ingested a tiny amount, the poor thing died.

    I like how well you explain how to do these jobs at home and walk us through step by step. I have a 98 ford f150 shortbed and I have just started a basic tune up. I decided to flush the cooling system after watching your videoes. I have no mechanical experience or training and with your videoes I have been able to change the read end on a mustang and paint the same mustang with spray paint, and fix its odometer

    That 50/50 antifreeze is a terrible waste of money. You're paying a high price for a half gallon of AF. Just keep an empty gallon jug around. Buy 1 gallon 100% AF, and pour half of it in the empty jug. Fill both jugs the rest of the way with water, and you have 2 gallons of AF ready to pour in your vehicle. Also, using that high priced distilled water to do this is a waste. Water out of your hose is fine for this use.

    I doubt dumping the chemical cleaner in the overflow first would do anything since it only gets pulled into the system if the pressure in the system is high enough to compressed the radiator cap spring. I may be wrong

    Your ratio isn’t accurate bc you still had 100% water in the heater core and the engine block which then mixed with your added 50/50 pre mix bringing that ratio lower say 60/40 or possibly 70/30 depending how much water was held in the block and heater core...maybe you already know this but just saying it for someone who needs it to be 50/50 all the way through in colder climates

    Is it really ok to keep the thermostat in when performing the flushes? I really don't want my car to over heat

    I just changed out my thermostat on my 3800 supercharger but I didn’t do the flush just yet. Whenever I do the flush (soon) would I need to change the thermostat again ?

    Is there a requirement to use distilled water with the chemical flush? I know you have to use distilled water with the antifreeze if you are going to make the 50/50 mixture. When I have done this in the past I have used tap water out of the hose for the flush. I used to have a Prestone flush kit in which you installed a Tee fitting in the heater hose and attached a garden hose. After running the cleaner through the engine I attached the hose to the Tee, put a spout in the radiator fill and turned on the hose and engine. When the discharge ran clear you were ready to drain and refill with new fluid...Pete

    A question i had was that what do you do with the distilled water that has all the gunk? Did you recycle it just like the antifreeze?

    Bought that Stanley black socket set. Been watching your videos for a while and currently working on my AC system following a combination of your instructions and the Chilton manual. Those videos lead me to this video. Now I'm fired up and motivated. I need to find me a part time job at a dealership or car repair shop to play with cars... LOL

    If you own a vintage vw just put a house fan in front of your engine for a while and that'll super flush it

    Took my car to get a coolant flush. Now my AC isn't cooling well. Any ideas? Have a 95 Monte Carlo z34. Haven't driven it much due to quarantine. When I turn my AC on now, not only is it not as cold there is a click sound. AC was working just fine (cold air and no click) but not anymore since the flush.

    4:00 that's actually air going in.The draining coolant is pulling a vacuum and the volume of coolant drained is being replaced with atmosphere..

    😂😀🤢😷Oh my, I wouldn't use my mouth to get the suction started. I would hope not, it is highly toxic and you can die rapidly. If any of you know anyone who drank even a couple of drops, call 911, Don't drive yourself to the hospital, CALL 911, AND START DRINKING, DRINKING ALCOHOL TO SAVE YOUR LIFE! I worked with the top expert on antifreeze poisoning, Dr. Donald Barceloux.

    Note: when you start it up yes turn the heater on and the fan on but take off the radiator cap off so air can bubble out, you really don’t need to drive it! Just a thought

    when you drain the radiator there is still almost half the coolant is still in the block. So after all the water was run through the system draining the radiator would not get all of the water out of the in the end by putting a 50/50 mix wouldnt it be more like a 75/25 mixture or so????
