How do i add antifreeze

Add anitfreeze in the top of the radiator. Lift the hood in front, take off the radiator cap and add antifreeze until it is full. Purchase Prestone
50/50 pre dilluted antifreeze solution at WalMart.

what kind of antifreeze?...radiator fluid?...if Rad fluid..look for your overflow tank, and add it there. The cap may be yellow, and may have "rad fluid only" printed on it.


gas line antifreeze goes directly into the fuel filler
windshield washer winter(antifreeze) goes into the wishy washy reservoir

Was it knocking in the radiator when it over heated if so you most likely got an air lock in the system by pouring the new antifreeze in to fast. You need to add it real slow and once you think the radiator is full start the truck and let it warm up and leave the radiator cap off until the thermostat opens and then add more antifreeze because when the stat opens the level will go lower. Once you are sure the antifreeze is circulating an full then you can go drive the truck. Some people use a 50 percent mix of antifreeze to water but I always use 100 percent antifreeze it runs cooler.

If it has dex-cool in it now then yes add dex-cool to it. So if the antifreeze is orange add dex-cool and if its green add the green antifreeze. It won't hurt it to switch the antifreeze but if you are topping it off, add what is already in it.

sytem capacity is 8.6 qts. you want a 50/50 solution, so drain alittle more than a gallon of the straight water out, and add 4.3 qts. of dexcool antifreeze or equivalent. i always go slightly stronger just to be sure, but not too much antifreeze as it doesn't work straight. no more than 4.5 qts.

drain the antifreeze ,then add water and when nearly full put about half a cup of caustic soda in the rad and run this for a day or so till teh heater get hotter then flush completely and then re add the antifreeze

Yes, water works fine. You just will need to add some antifreeze to the system before freezing weather arrives. If you have antifreeze in the vehicle and are just diluting it some, then drain it about halfway and refill with antifreeze when winter arrives. If it is empty and you are just putting water only, then if your engine is an alluminum block and head, it will be fine for now with just water. If you have a cast Iron block, then you will need to add antifreeze to lubricate and prevent your block from rusting on the inside!

Yes you can add water to the max line when the engine is hot or to the other line when it's cold. It's not unusual to loose coolant over time. You can usually find another brand that qualifies for the manufacturers brand. You can get an auto supply store to help select it. Some manufacturers don't recommend an antifreeze with silca as it can damage the water pump.

Most vehicle Mfg.'s do not want you to access the radiator, so they put in overflow tanks.
You can add coolant there. You will find it under the hood next to the interior fender.
Only check or add coolant when the engine is cool.
I would start looking for a coolant leak. Vehicles are not supposed to leak or lose their coolant.
Check for green coolant spots on the ground where you park your vehicle.
Please let me know what you find.

50/50 mix will take care of it
