A diagram of the flushing of a radiator and block of a chevrolet blazer LS 2000

Theres no such thing as a diagram, here are the draining instructions, hope this helps...
  • 1-Place a large drain pan beneath the radiator drain plug. The drain plug is located on the passenger side at the very bottom of the radiator on the engine side.

  • 2-Make sure the engine is cool. Open the hood of the truck and remove the radiator cap.
  • 3-Loosen the drain plug. On the 2000 Blazer, the drain plug is a wing-nut type of plug. Twist it with your fingers until the coolant begins to drain.

  • *To flush the block, once you have drained the radiator, run the engine for a bit untill the temp gauge goes up to normal, then the coolant will have been evacuated from the block. DO NOT leave the engine on, once it reaches normal temp, (this will happen quick) turn off right away, otherwise you'll be forking out a few hundred $$$ to fix the worped heads.
    4-Tighten the drain plug with your fingers once the coolant has drained fully from the radiator. Remove the drain pan and dispose of the used coolant properly.
    Some service stations will take and recycle your used coolant.
    Hope this helps...

    I need to bleed the radiator system. Where is the bleed valve?

    Uncap the radiator, and unscrew the radiator drain plug. Normally, this drain plug is located on the inside bottom of the radiator, but models will vary. Once the drain plug is unscrewed, coolant will rush out into the drain pan. If there is not a drain plug, then disconnecting the lower radiator hose will be adequate.

    Where is the drain plug for the radiator

    Should be a drain **** at the bottom of the radiator that unscrews out. It looks like a wing nut has been welded to a bolt on the end of it. Another way to do this is just pull off the bottom hose.

    Have to replace water pump on 98 Ford Taurus. Any hints or suggestions would be appreciated before I get out in the snow and cold to fix this.

    You can change the water pump by doing these steps:

    • With the engine off and cold, o pen the hood and locate the vehicle’s radiator and water pump.
    • Remove the radiator cap.
    • Install a pressure tester on the radiator. Apply the pressure indicated on the radiator cap or in the owner’s manual.
    • Inspect the water pump for leaks. Remove the pressure tester.
    • Place a drain pan under the radiator. Open the drain valve or remove the lower radiator hose to drain the cooling system.
    • Remove the drive belts or serpentine belt.
    • Remove any hoses connected to the water pump.
    • Unbolt the water pump from the engine. Remove the water pump.
    • Using a gasket scraper, clean the mounting surface on the engine block.
    • Install a new gasket and attach the new water pump to the engine with the original mounting bolts. Tighten the bolts to the manufacturer’s specifications.
    • Re-install any hoses and belts that were removed.
    • Re-install the drain plug or lower radiator hose.
    • Refill the radiator with a 50/50 mix of coolant and distilled water. Pressure test the cooling system and check for leaks.
    • Check and fill the overflow reservoir with coolant.
    • Leave the radiator cap off and start the engine. Idle the engine to remove trapped air from the cooling system. Add coolant if necessary.
    • Install the radiator cap.
    • Road test the vehicle and monitor the temperature gauge. If the vehicle runs hot, there may be an air pocket in the cooling system. Allow the engine to cool off and add the necessary coolant.

    Drain cooling system

    Make sure the engine is cold before you drain the cooling system. First remove the radiator cap. Under the hood on the bottom of the radiator you will find a drain plug. You turn it counter clockwise and drain the coolant into a container. After it has been drained add new coolant using the half and half (half coolant half clean water.) After having added the coolant. Be sure to add the kind of coolant that ,("goes with any color".) Replace the radiator cap.Run the engine to operating temerature then be sure to bleed the cooling system. They have a bleed screw near the thermostat housing . (That's where the hose from the radiator connects to.) Make sure all the air comes out from the bleed valve screw until coolant starts coming out. Tighten the screw and let the engine get cool again. check that there is coolant in the container where it says coolant only near the radiator.

    Need to drain coolant from 1998 Olds Intrigue. What is best way? (3800 Engine)

    1998-'99 Intrigues equipped with the 3800 engine have a specific process for replacing antifreeze. It is somewhat of a lengthy process and you should refer to your owners manual for doing this. After you empty and flush your system with water (garden hose), only fill the system with green 50/50 antifreeze, NOT Dex-Cool. Avoid Dex-Cool. If you bring your Intrigue to a shop to get serviced, make sure and inform whoever doing repairs and/or leave a note (clearly visible) to NOT use Dex-Cool if they're doing any work pertaining to cooling system.

    I need help on replacing a radiator on my 2000 chevy cavalier

    Disconnect negative battery cable. If you have Delco Loc or Theftlock audio system, turn off feature which reqiers disconnecting the battery. Make sure engine is cool and turn cap slowly to release pressure. Drain cooling system. Disable airbag system by disconnecting the electrical connector from the airbag system's forward discriminating sensor located on the hood latch support bracket. Remove the cooling fan and shroud assembly. Next loosen clamps for upper and lower hoses then Disconect from radiator. Disconect the coolant reservoir inlet and outlet hoses from radiator. You will need a couple drain pans and rags. If your car has an automatic transaxle, Disconect it from the left side tank of the radiator. Use a back-up wrench on each welded nut while loosening the cooler fitting. Be careful not to bend or brake any lines when loosening the fittings. If they are tight spry some WD-40 and wait about 10 mins. Plug the ends of the disconected lines to prevent leakage. Remove right and left head lamp assembiles. Remove hood latch support brakets from radiator crossmember. Remove condenser mounting bolts. Remove the radiator upper mounting bolts located at the upper left and right ends of radiator's side tanks. Now carefully remove radiator. To install just follow directions backwards. I hope this helped.
