hi.
there is usally a coolant level switch just underneath the coolant bottle to tell you if the coolant level gets too low. check that the wires on this switch are ok. if they are, then the switch should just unscrew/unclip to change it for a new one.
it should be a fairly easy and quite cheap repair.

hope this helps.

You will have to drop the transmission. Inspect the pressure plate for excessive wear and stretched springs when you remove it. Replace your throwout bearing at the same time, they are usually worn out by the time you need a clutch.

Taking flasher control away from the CPU is not difficult. I had to do this on an 81 a few weeks ago as flasher was burned out and not able to find a replacment CPU. On the 81 there were only two wires that were involved with flasher control. Both were at one end of the CPU connector. Green with White Stripe was power in from the turn signal switch and Green with Black stripe was output to the turn bulbs. I simply removed the wires from the connector. Soldered in two spade connectors to the wire ends and connected these two wires to a basic 2 pin flasher unit. Works like new!!

Check that on your carburetor, when you press on the throttle, it still shoots a little bit of gas out into the barrel. If it does not, you may need to replace the throttle pump. what is happening is this: As the throttle is opened higher, the vacuum drops severely, and the fuel doesn't get put in. The throttle pump pushes a little squirt to retain the vacuum. If it is an EFI unit, you have other issues, that I would recommend a mechanic for.

Should be the black wire. And the battery will have a + sign for positive and a - sign for the negative.

On the RX7 it will most likely be a fuse. If you do not have a service manual refer to automd.com and search for the basic guide on replacing a fuse. Should you need specifications, head over to your local auto parts dealer for a book outlining the specifics on your fuse box or module.

Do you have wiring diagrams?

Not to be hurtful in any way,but do you
understand vehicles at all, or the systems
on the one your working on?

for starters -- the battery is going to be shot,, and the gas in the fuel tank is going to be bad,, and yes' look at all the hoses and belts for cracks and splits. it would also be a good idea to change the oil and spark plugs. check the tires for cracks and also check the air filter box and filter.
if you have any troubles along the way -- please feel free to write back and ask me.

You need to take it to shop or good parts store with OBII scanner. They can reset your lights provided there isn't a problem.

Check to see if you missed a bolt first. What I have run in to often, is the input shaft gets stuck in the pilot bearing. Raise the trans as far as you can and release toe jack as low as you can a few times. Also try moving the whole trans side to side as far as you can and the shaft will work itself loose. You can also carefyully slip a pry bar in between the flanges on each side and pull both together and some times that wiill pop it out. When you make the final pull try to have the trans with an imaginaty line with the engine crank shaft if both are aligned it should come right out.

Hi there,

My name is Mike. A couple times a day I go looking around to give some pointers to our clients (you).

Look at it your question from our point of view, at this point no one here has a clue which diagram, for which model, which year or which specific configuration you need. We need a little more info.

More is better:

If you are serious about getting an answer, include Make, Model of the product that's misbehaving and what type of product it is.

Describe your problem clearly, concisely and with as much detail as possible.

For future reference:
Often, a problem can be the result of a seemingly unrelated event. It is always a good idea to include a recent history.

Additional information such as what steps have already been taken, has the product ever worked, is it new, etc. can have a bearing on providing the best solution for your particular circumstances.

Remember, you are a key participant in this process. We are not there, you are. We depend on you to be our eyes and ears. We can only respond to what you provide us. Without you, all our talent is worthless. How's that for an ego build?

What you get out of the experience depends on what you put in to it. So help us help you.

It would be also be advantageous in your case to repost your problem so that it is correctly categorized and starts over at the top of the queue. This way it can be directed to someone with expertise in the area you need. They may have the manual memorized. Who knows?

Best regards

Mike

There is a special Radiator funnel that is made just for this purpose. You can buy them at most auto parts stores. You install the funnel, fill with coolant and allow the engine to run up to operating temp. It will expell air and **** down coolant from the funnel as it is running. Very easy to use. Good investment for a few bucks.
