Coolant Problem and starting problem
Everytime I start my car the coolant buzzer/light comes on . I filled the thing up with fluid raidiator all the way up to the cap was full even the overflow is where is should be . I don't have any visible leaks which is leading me to think that the seals went bad . But is that was the case I would't have compression would I ? I am not getting any hesitation or anything just no mater how full it is the stupid buzzer comes on ?
On the other hand the other day I went to start my car and it was hard to start like it sounded like it was backfiring but it wasn't backfire just sounded like it . I had to give it some gas to get it going its happend twice now in the last day and a half ?

I can only tell you what I've learned so far.
For the buzzer, you need to bleed all the air out of the cooling system. However, I just drained all my coolant from the hoses and the drain, just not the engine block. I then filled it up and let it warm up while I was attending to it. THe buzzer never sounded, but you can check it by pulling it out the radiator and waiting a few seconds.
The backfiring sounds like emissions. Could be anything, but I suggest adjusting before replacing. YOu can get a multimeter and check several things. I just adjusted the TPS with $3 and some parts I had lying around.

Probly just air stuck in th system, make even more sense if the buzzer keeps turning off (coolant is sloshing around). Trouble starting could also have to do with the coolant sensor reading being out. If you have an air bubble around the temp sensor you'll get a false reading. You ECU uses the temp senor reading to help it control the A/F mix, especially while the engine is cold

If it's air then close the radiator cap, squeeze a hose repeatedly, remove radiator cap, add coolant, repeat. That won't do much, but it'll help. If you're able to add more coolant after doing this, then you definitely removed some air. Later get the Lisle funnel (forum search for more info, Google search to buy) to do a more thorough job without any hassles.
www.aaroncake.net has a cooling system diagnostics section in case it turns out to be something worse like the seals.

I kind of suspected there might be an air bubble in the radiator especialy because when I go around turns it comes on . Yeah if I have the cap off and squeeze the hose little buble come up . Ill check out the funnel

I remember getting that buzzer a few times, until I learned how to refill my coolant correctly (no air bubbles).

This happened to me one time, all i did was removed the bleeder while filling the coolant but be careful because I didn't know coolant could come out of there. After you close the bleeder cap. Bam! It was fixed when I started up the engine.

By bleeder to you mean the sensor in the top of the radiator if so I have tried that . I am looking at draining the coolant and refilling it with the lisle funnel now .
I dunno if this has to do with it but when the car get up to 5k and 6 k it hes's when it hits 5k and then when it hits 6k . I think the fuel pump on the car is to big for the FPR could that have somthing to do with it ? I have delt with hes problems in the past an know how they can be fixed . looking for a second opinion on that one . What would cause backfiring somtimes when I turn off the car I'll hear a little pop about 5 seconds later ?
