I searched and couldn't really find anything. I know you might think I'm dumb or something, but that's ok ..........where in the heck do I add the coolant? Please post a picture or something. There is like 3 caps and I don't know which one I add coolant to. Please advise as soon as possible. Thanks.
ast is attached to the intercooler which is more to the drivers side. The other one is the coolant filler neck which is attached to the engine more on the passenger side right next to the air pump. the overflow tank is the white (ish) colored tank on the passenger side right behind the headlight.
A nice variation on adam c's method is to open the filler neck (this is the cap on the engine itself, the furthest rearward of the caps) the AST cap (the one right next to the battery), and pull the throttle body coolant return line on the backside of the throttle body (the hose points towards the passenger side of the car and is held on by one of those stamped steel hose clamps). Start slllooowwwwlllyyyy filling the system at the filler neck (the one on rhe engine )until the level reaches the top of the AST. Cap the AST at this time. Then keep filling. You will hear a gurgling sound at the TB coolant line. Keep filling until coolant just comes out the TB. Put the hose on. Fill any remaining coolant needed in the filler neck and cap it. Make sure the overflow tank is filled to at least halfway full, 3/4 is the best. Start the car and run it until the radiator becomes warm, and let it run for about a minute once the rad is warm. Shut the car off, let it cool completely, open the AST and top it off, then open the filler neck and top it off. You should have very few air bubbles after this, and those should work their way out through the overflow without needing any more coolant added to the AST or filler neck. That's my two Lincolns (the funny tasteing ones!)
It will lead to all of them, BUT if the AST cap is on while filling the system, you will end up with a pretty large air space in the AST, specifically from the upper hose connection (the one to the thermostat housing) to the top of the AST. This air space will eliminate the possibility for the overflow system to deal with coolant expansion and removal of bubbles (such as arise from boiling in the turbos. Note that those housing easily reach 500 C during normal operation, so the coolant DOES boil, which is why the AST was placed in the car in the first place). Further, the filler neck is NOT the highest point on the engine coolant system with the TB line in place, and this is the other place air bubbles can and do get trapped during coolant refill.
guys: I think he's just trying to add a little coolant, not fill the system. Just check the level in the overflow tank. If you need to add some coolant, open the filler cap and add some.
RX7SpiritR: Give us a break. I understand that the three caps make things a little confusing but to not even know what people are talking about is pathetic. Look in your damn owner's manual for christ's sake. If you don't have one, download it for free from www.iluvmyrx7.com We'll help you but at least have the courtesy to make any effort at all....
dang dude calm down. This is where people come to get info....FRIENDLY info and advice. I just wanted a diagram. Just calm down, no need to get all hostile. Thanks for being nice in the begginning but geeze. I don't have a manual and I didn't know where to get one. Thanks for letting me know where I can get one. But please be nicer in the future. I have A.D.D. and sometimes it's hard for me to concentrate and understand things. Thanks for being so understanding as to what my disability is!!! Next time think about it hard before you go accusing and yelling at people because now you hurt me and I'm in a bad mood now. Thanks a lot you jerk! But thank you for some helpful info everyone.

I wasn't accusing you of anything. It appears from your posts that you weren't even trying to discover this information on your own. This information is basic knowledge of the car and you would know it if you read the owner's manual (or even better, looked at the service manual).
I'm sorry you have a disability. I really do try to help people and contribute to the forum when I can, but I don't have much patience for people who spend absolutely no effort in finding the answers for themselves first. If you did spend effort and just didn't understand it, I apologize.
well number one would be the fact that like I said I have no manual. Number two I'm at work, can't do much from here. And number three would be the fact that I don't have my car right now, it's in the shop and I get it back tomorrow. The coolant light was going off before I took it in and I didn't know what to do so that's why I asked you guys. But please don't get mad at me, I was trying, but I can't look at the car or aanything like that right now. The first couple of posts would have been fine, but I would have forgotten once I picked up the car. I at least have a picture now that I can use. I didn't mean to get mad at you but I just got mad that I was being yelled at for asking questions. Just couldn't do anything that's all. You have to understand my position at this point please. Thanks though. I too sometimes have no patience for incompitent people, or people that don't get it from small explanations. I just wanted to make sure that's all.
If you just want to remove a few cups or so of coolant, the best way is to do it "fishtank style", get a length of nylon hose and sort of suck it out until it gets going and then it'll just keep draining. You can also pick up the kind with a pump so you don't have to risk getting coolant in your mouth. Also note that the overflow bottle is not connected to the rest of the system per se, so filling up the overflow will not add coolant to the filler neck and ast and vice versa.
