You don't give engine size, but I suspect it'll be like most crossflow radiators. Typically a crossflow radiator won't hold much more than 4 quarts (if that much)....but DON"T BE CONFUSED by this number, it is only what I think the radiator itself will hold (which was what you questioned). Overall the cooling system (radiator, block, heater core hoses, etc. may well hold 12 to 15 quarts.

A vehicle specific repair manual (obtainable at a auto parts store) should provide this info.

Once you've established the total cooling system capacity, fill with a mixture of anti freeze and water at a 50 / 50 ratio. You can buy premixed antifreeze and not have to worry about getting the correct ratio. When replacing the coolant, you might want to consider adding a water pump lubricant / anti rust additive.

If the cooling system is dirty, flush until clean before adding back any antifreeze or other additives.

While you have it down for draining, cleaning, etc. is a good time to look at replacing your radiator, heater and bypass hoses (if so equipped). Might also want to consider a new thermostat at the same time.

Once you have all this done, make sure you don't have any air trapped in the system that can reduce the cooling effectiveness. Usually if you'll run the engine until the thermostat opens and the coolant level drops, you can add enough coolant to fill and this will probably take care of any trapped air issues. It's a good idea to check the coolant level after it has completely cooled (say overnight) to make sure the radiator is filled to the proper level (usually about 3/4" below the neck)

On the 4 cylinder you will need 1 1/4 gallons of antifreeze mixed with an equal amount of distilled water for a 50/50 mix. On the V6 you will need 1 5/8 gallons of antifreeze mixed with an equal amount of distilled water for a 50/50 mix. Make sure and use the correct type antifreeze.

Install a radiator in 1998 buick skylark


Jack the vehicle up and then place a jack stand under the A-arm. Complete the same process on the passenger side of the vehicle. Jack the vehicle high enough to allow placement of at least a 3-gallon bucket under the radiator.
  • 2Locate the drain valve on the left hand side of the Skylark's radiator toward the bottom of the radiator. Place a 3 to 5-gallon bucket under the radiator in a manner that will allow the bucket to catch the fluid.
  • 3Turn the valve open with your fingers. If the valve will not open with your fingers use a small pair of pliers to open it. The further you open the valve the faster the fluid will drain.

    Radiator fluid disappers with out a leak


    Half a gallon a week? Bad for the car, bad for the pocketbook.
    Have a shop do a pressure test of your coolant system to check for leaks. You might also want a block test where they check for exhaust gases getting into the coolant system-maybe your coolant is getting into a cylinder and burning off. How does the car run? any white smoke out the exhaust? Or signs of overheating?
    That's kind of a worst-case scenario (head gasket problem, or cylinder head problem), but that's an awful lot of coolant loss, and it's got to be going somewhere.
    Good luck.

    How do I change the radiator fluid in my 95 cavalier?


    OK, turn the car off and use a screwdriver to remove the lower radiator clamp and drain it out there into a wide mouth container that holds a few gallons of fluid.

    Then, you can replace the lower radiator hose, and fill with a 50/50 solution of radiator fluid (coolant/antifreeze) of your choice (brand wise).

    This method is very good for getting a lot of fluid out quickly since the lower radiator hose is rather large compared to just opening the petcock if so equipped.

    Radiator fluid coming out opening just below radiator cap


    There is supposed to be a hose there. It goes to the overflow tank (should be a clear or semi-clear tank, maybe a half gallon in size, somewhere behind the radiator off to the side). Look for the tank, see if there's a hose attached to it, and that hose will attach to the small flange where you are seeing the coolant leaking out.

    Likely have a restriction in cooler flow.The radiator has a tank built into it that cools the trans fluid,if it's restricted,the fluid flow will also be restricted.Disconnect cooler RETURN line,after the radiator,and put into a gallon jug.Have a helper start the vehicle with the selector in NEUTRAL,and measure cooler flow after the radiator.It should be minimum 2 quarts (1/2 gallon) in 20 seconds.Good luck.
