helping friend - once again, coolant buzzer goes off at low rpm
Well basically helping out my friend once again! I was driving it around to see wut is the problem. The coolant like buzzer comes on low rmp and at idle. Once the car reach 2500rpm or higher the buzzer turns off. I check the reservior tank and filled coolant. Also i notice his reservior tank level always changes everytime he starts his car or drive it. It went from low to high to overfill to empty.

Check it out...the only way coolant can go to or from the resevoir is the pressure bypass valve on the cap on top of the radiator, so if coolant goes to and from the resevoir, you probably have a bad cap, my reccomendation: replace cap, or if you want to be legit about it you could pressure test it but its a 3 dollar part so you should probably just replace it.
P.S........your motor is blown.........i'll give you $100 for it.

I posted about this before I think, It worked for me.
Unscrew the Sencor in the front black coolent tub.
This will take all the air out of the car and when you put it back on add more threw the radiator cap, run the car for a bit and the buzzer stoped going off for me, I had to do this after I did a Coolent flush, the buzzer hasn't been on since.
try that, it worked for me.

You need to find where you're losing coolant. If it's dripping externally it's pretty simple to find. Common places are caps, hoses, water pump, thermostat neck. If you can't find an external leak, you're losing it inside.
Make sure your coolant is 100% topped off. Fill the radiator to the top. Cap it. Remove the hose/T-neck cap. Fill to the top. Cap it. You can also use the "air bleed screw" on the top left of the radiator to remove air pockets... you don't have to turn it very much.
Poor man's coolant seal check... with engine cool, remove your EGI fuse, remove your radiator cap. Have a friend crank the ignition while you watch for bubbles from the radiator. There shouldn't be any. If there are, you have a coolant seal problem.

From full as in the whole reservior over flows to half full to empty to like full again.

Still sounds to me like there are air bubbles sitting right on that sensor. This same thing just happened to my car, right after I changed the water pump. Had a bad clamp on the upper rad hose, so I just replaced the hose and clamps. For a day or two, I'd occasionally get the coolant buzzer at idle or on cloverleafs. When I'd stop, I'd just top off a little coolant until it stopped. I wouldn't be too worried, unless you have steam coming out of your exhaust or something. Then worry.

dood, go to your local mechaninc and have them do a coolant system pressure check.....they remove the radiator cap, put oon another cap with a pump at the end and pump it a couple of times the coolant will begin to squirt out of wherever there is a leak......when I checked my car 3 little sprays of water shot out from the thermostat neck........
CUT the coolant warning WIRE?????are you retarded?

DON'T kill your buzzers dude. As annoying as they may be, they save your motor. I caught an oil leak because I heard the oil buzzer go off for a split second as I took a corner... I would have never noticed the light that briefly and I was about to take an 800 mile round trip in a couple days. Luckily it was just something really minor.
Fix the problem, don't kill the buzzer. Replace the radiator cap, bleed the air out of the system, and if that doesn't work get it pressure tested.
