Varies form car to car. Please ask a new question with year, make, model, and engine size.
The amount of coolant to fill a Regal radiator depends on the engine size. A smaller motor might only use 1.75 gallons of coolant, while a larger motor could use 3 gallons.
Start with a cold engine.Remove the radiator cap and fill the radiator with Dexcool coolant (I think it's a red/pink color, not the usual green. DO NOT use any other product.)If the radiator was very low, start the car and add coolant as far as you can. Running a cold engine without the cap won't harm anything and allow air to escape from the cooling system.Replace the cap and add coolant to the overflow bottle. I fill it to the "cold line" so that I can see if it needs more over time.Drive the car and check for changes in the cold level. If coolant is still being lost then you must decide if you want to continue replacing coolant or take it to a shop for proper repair.
To actually "flush" the coolant in this vehicle you will need a flush machine. To do that we did at the dealership, drain the radiator (you need a 1/4 inch ratchet and 1 inch extension) then use a vacuum fill too to fill with new coolant.
It will be safe to drive short distance as long as the car does not over heat. You can top up the engine coolant or use water/coolant mixture till you fix the problem which could be leaking hose pipe. leaking radiator or faulty radiator cap
Allow the car to cool. Remove radiator cap. Add water or coolant to fill radiator. Start engine leaving cap off. check to see if coolant is circulating in radiator. Locate upper rad hose, and squeeze to move air bubbles out, or to ecourage circulation. If large air bubble works its way out, add coolant to fill. Once coolant starts to expand and spill out, replace cap. Watch temperature gauge to esure the problem has been rectified. You may have to repeat this procedure.
I need to fill my car's radiator with antifreeze before winter comes.
The 1999 Wrangler is equipped with an overflow tank. The amount iof coolant to add to the radiator is slightly less than 2 gallons. Be sure to use either a 50/50 coolant (pre-mixed with water) or a gallon of concentrated coolant mixed with an equal amount of water. You will have about 3/4 inch of coolant left in the container when the radiator is full. The overflow tank is there to hold coolant when the radiator gets warm and needs to expell some of the coolant. So just fill the radiator with coolant. You'll know when it's full.
You need a special tester called a block check. You fill it with a special fluid and then use it to suck fumes out of the radiator . if the fluid turns yellow it means there is exhaust gasses in the coolant.
After water pump or t-stat replacement, this is how. First, close the pet-cock at the RF side of your radiator. Make sure to use "Toyota" brand coolant and buy the concentrate. Mix it to a 50/50 ratio with water. Fill up your radiator. Make sure the overflow bottle is empty. Once the radiator is near full, use needle-nose pliers or a channel-lock wrench to remove the clamp on the upper radiator hose. Fill the hose with coolant, then re-install. This will fill up the thermostat housing and cover the CTS(Coolant Temp Sensor). Note: Make sure to remove the hose from the top of the radiator next to the filler cap: Start the engine and let it warm up. Once the t-stat opens, the coolant should start moving through the radiator. Make sure to leave the radiator cap off. Top-off the radiator after it warms up. Replace the rad cap. Fill the overflow bottle half-way. Drive it for 5-10 miles. Make sure to run the heat on full blast while your driving. After the drive, park the car and let it cool down. Remove the rad cap only after the engine has cooled down completely. Top-off the radiator again and fill the overflow bottle half-way. Drive the car for 30+ miles, then check the radiator again. You may need to top-off once more _-+=
The assumption is, the engine is hot and if you open the radiator cap you will be sprayed with hot radiator coolant. If I'm not mistaken, didn't the 95 Buick use the "permanent" radiator coolant? If so, don't change it until the specified time. Just don't open it while it's hot. Do it when the car is cool.
Tap water will be fine - but if you live in a country where there are freezing temperatures, you will also need to add antifreeze (in the amount stated on the bottle). Tap water works in a pinch,, but to properly fill your coolant system you should use a 50/50 mixture of Distilled Water and Antifreeze
Drain the collant from the radiator by opening the stopcock on the bottom left (looking towards the front of the car)of the radiator. Remove the cap from the overflow tank to speed up the flow. When you are ready to refill, close the stopcock and fill the system from the overflow tank. Do not use cheap coolant since the aluminum engine block corrodes more easily than a cast iron block.
