What is total capacity of your car's cooling system? How much fluid does the radiator hold?
Use 50 percent high quality anti-freeze and 50 percent tap water.
Is the radiator new or re-cored? Ask the manufacturer what they recommend for anti-freeze.
Aluminum radiators may require a special anti-freeze.
Good Luck!
I need to fill my car's radiator with antifreeze before winter comes.
Use a 50/50 mix of antifreeze and water and fill SLOWLY to prevent an airlock through the top of the radiator
50% anti freeze 50% water, so use half the bottle and the other half of the antifreeze in the bottle top it off for water for next time
use half water half antifreeze to the fill level
PUT IT IN THE RADIATOR. MAKE SURE YOUR ENGINE IS COOL AND USE THE DRAIN COCKPIT LOCATED ON THE BOTTOM OF YOUR RADIATOR TO DRAIN ENOUGH OF THE FLUID TO ACCOUNT FOR HOW MUCH ANTIFREEZE YOU ARE ADDING.
If your use anything more concentrated than about half anitfreeze and half water, the radiator water will freeze at a considerably warmer temperature. There will be less protection. Also, antifreeze actually helps keep your car running cooler in summer. If you use straight antifreeze, the car will "boil over" at a much lower temperature. There will be less protection.
Most lawn mowers are air cooled, and do not HAVE a radiator (so no antifreeze). If you have a mower with a radiator, you will need to check with the manufacturer to see what they recommend.
You should always use a 50/50 mix of antifreeze and water.
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
Yes, you can add antifreeze / coolant to a car without flushing the radiator. It's best to use the same type that's already in your car / truck - conventional or long-life. Antifreeze / Coolant comes in 'Full Strength' which needs to be mixed with distilled water (usually 50/50 for mild weather regions, and more antifreeze 70/30 for really cold weather regions.) Also available is pre-mixed 50/50 antifreeze. PEAK Antifreeze & Coolant protects from -84 degrees to 276 degrees Fahrenheit when mixed 70/30. If it's been 2-3 years since a flush & fill for conventional antifreeze / radiator fluid, or 5 years for 'long life' antifreeze, it's likely time for a flush & fill.
From the radiator reservoir located at the top driver side of the engine compartment, you fill it up with at 50/50 mixture of GM Dexacool Antifreeze and Distilled Water. Make sure that you use the stuff that says GM Dexacool or else the engine will not cool correctly. Trust me. I know from experience.
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.
