How do I change the antifreeze on my car?

Question

How do I change the antifreeze on my car? I had to put in water over the summer when the car overheated and I changes the thermostat. But now, with the cold weather, I need to empty the water and put in 50-50 antifreeze.

How do I accomplish this?

Answer 1

drain it and refill with 50/50 making sure you dont get any trapped air bubbles, look for a bleed plug at the highest location.
and remember not to drain it into a storm drain, it is a biohazard :(

Answer 2

At the bottom of the radiator should be a nut which, when loosened will let the radiator empty. Alternatively, you can disconnect the bottom hose and empty it that way.

As a quick point, it is not a good idea to run plain water for too long - as anti-freeze is used not only to prevent freeze-ups but ALSO contains a corrosion inhibitor.

You might well find your water is a little rusty looking when you drain down, don't panic unduly, but you might then want to put the garden hose i the top of the radiator and keep it running until the water is running clean. THEN drain down. put pipe back on (or tighten up the bolt) and then refill.

Answer 3

Simply lay on your back, shimmy under the front of the car where the radiator is(pull a nice size flat pan under with you to catch the fliud you are going to let out) search for a butterfly shape valve(adjustable wench needed) to open the radiator drain valve and let the water drain into the pan untill the radiator is empty. Close the valve and, come from under the car and refill your new concoction through the top of the radiator after taking the pressure cap of. Note; use eye goggles when working underneath and check for any leak at the drain valve and you don't have to remain under the car while it is draining.

Answer 4

Unscrew the drain plug at the bottom of your radiator and let the liquid come out them flush the radiator out with a water hose or special flush liquid from the cap on top of the radiator put the plug back in and fill the radiator back up with 50/50 put the cap back on and there you go!

Answer 5

on the bottom of the radiator theres a relise mechanism that looks similar to a wing nut turn it till the old antifreeze starts coming out then let it all drain out and then tighten it back up and add the new antifreeze till its full then start you car let it warm up then cool off and check it you will prolly have to add some more antifreeze and thats it nothing to it good luck catcha later bro

Answer 6

There's a drain on the bottom of the radiator. Drain the radiator, and then pour in the antifreeze.

Answer 7

probably go pay to have it drained, flushed, and filled. If you want to do it yourself, find the drain plug, put a container under it, drain, flush with a garden hose a couple times, put plug back in, refill. If your have an older car, I suggest you do it yourself, if you really dont know much and it is an expensive one, put out the 100 bucks or whatever to have it done by professionals.

Answer 8

start your engin. open the peacock valve on the bottom of your radiator, let all the water run out including the water in the block. watch you temp. guage. do not over heat to a boiling point. shut off engin, let cool, install anti freeze depending on the size of your raditor. then top off with half water.

Answer 9

you drain out enough water so that you can replace it with anti freeze. I think you remove the bottom radiator hose to allow the water to flow out. there may be a plug somewhere but I don't think so

Answer 10

It sounds to me such as you have a Toyota. (you haven't any longer reported what form of vehicle it is). that's particularly significant to no longer blend coolants with diverse colours or from diverse manufacturers. all and sundry that tells you that coolant is usual is under-knowledgeable (study stupid) in this undertaking. Coolants of diverse colours blended mutually will inevitably reason gelling issues. perfect now, GM is in touch in an high priced lawsuit against their Dex-Cool form because of the fact the chemical compounds in it have been shown to eat away at gaskets ( and intake manifolds) and reason untimely engine failure. the common "eco-friendly" coolant ought to be OUTLAWED and not be used in something!!!!! interior the previous days while American engines the place made up of one hundred% forged iron, the "eco-friendly" stuff became perfect (yet nevertheless no longer all that sturdy). It led to untimely gasket, radiator fin, water pump and heater middle placed on and failure. The extra recent colored coolants have been designed with specific advantageous properties that make larger provider existence and forestall corrosive build-up and water pump bearing failure. crimson coolant frequently ability that that's formulated to be silicate loose and phosphorus loose. different colored coolants have much extra homes. foreign places vehicle anti-freeze is fairly diverse (and extra effective). while you're uncertain, have your gadget flushed out and use Mercedes Benz (gold) coolant. while you're using a foreign places vehicle, USE THEIR coolant!! The MB coolant will artwork merely effective in ANY vehicle and could final for over one hundred,000 miles. Doing so will ward off the destiny use of flushing out the cooling gadget in any respect!!!!
