ok lets say u drained all ur antifreeze out right, now what would be the proper way to fill it all back up? are u supposed to pour it strait into the radiator or into the overflow tank? but then overflow tank is so small so i dont see how that would be enough. and how much coolant do u need altogether (by coolant i mean antifreeze that has already been mixed 50/50)

 

One Jug of prestone is about all you need just funnel it in and what ever you have left put it into the overflow tank....

 

by jug u mean the big bottle it comes in? and funnel it into the radiator?

 

YES you have it....

 

also, remember to let the coolant settle into the system. if you are pouring it in using a regular funnel a lot of air pockets are going to form.

you can try to push some of them out by squeezing the main line lightly.

 

If the system is completely dry you also need to make sure that you get all the air out of it after you fill it. You should check the manual or get some conformation on this cuz' I don't have mine handy, but I think it goes something like this:

Set the heat all the way on high to make sure that coolant is flowing through the heater core and no bubbles get trapped their.

Add coolant to the radiator with the engine running until it's full.

Open the bleed screw (don't take it out) until coolant flows out in a steady stream. If your **** you can connect a small length of rubber hose onto the bleed screw and rout the coolant past the block onto the floor.

You may have to go back and top off the radiator/bleed again until all the air is out and it's full. And note that the rad had a bit of an S in the neck so don't try to visually gage how much fluid is in it, just poor until a bit spills.

I had about 2 days of driving where I had to do this periodically after draining and filling the system. But I don't hear other people having the same problem so maybe I just got some really badly trapped air bubbles...

never put in coolant in your radiator when its empty if your engine is hot. that **** can crack your block

 

 

and you know what I have never had any trouble refilling my radiator with a funnel of course my engine is cold when I do this work and I have a C&R so that could have something to do with it. If you use a small enough funnel to where you can keep the fluid at the top while pouring the antifreeze in then it goes into the radiator with very little air in the fluid you will not have any problems. If you want to be safe then with the engine at full operating temperature then release the bleed valve enough to clear the air bubbles out then you have it....

 

I thought you were supposed to let the car run for a while with the rad cap off to get the air out.

 

how cold does the engine have to be before u can dump in new coolant?
