You might just have air pockets in the cooling system. Top it off, then cool it down, then top it off, etc. until it won't take anymore. You should also get the system pressure tested to find out if there are any leaks.

 

All this and not once have you mentioned that you checked the coolant level when the car was cold ?? ? ? ? ? Was the level topped off each time before you drovee the car ? ? ? ?

 

sorry guys i checked coolant i bought some yeterday
and put some in didnt need any i put some in to reserve tank
just in case

 

Go out and get it pressure tested as soon as posible. You might want to check the wire to the sensor as well; that it's not frayed and grounding out.

 

p'cola fd im having issues with the ecu i also forgot to mention
the ecu is showing me a constant check engine light.
im suppose to get a another ecu this week do u think that might be the case or something.. pls help

 

yea sucks i didnt see or smell anything man hopes everything turns out good...

 

Have you checked to see what code your ecu is throwing? The coolant level sensor should not send off a check engine light(I think).

 

no havent checked checkengine yet i will on fri morning
my friend just scared me told me my motor is going south
same thing happened to his.mixed with oil it didnt leak though
is that tru
im sorry im dumb on coolant rx questions.

 

If it's leaking into your oil you will notice that the oil on the dipstick looks milky. If it smells like coolant from your exhaust or you get little champagne bubbles in the coolant when you crank it up in the morning, then you need to save for a rebuild. It only takes about 5 minutes to check your check engine light codes. Just get a little wire and jump the TEN and GND pins in the diagnosis box under the hood. Note how many long and short flashes there are.

 

You can also try checking your thermostat. I had the same problem a while ago and changed the thermostat, radiator, and AST at the same time. Keep topping off the coolant and see if the buzzing goes away.

 

Hey I just had a problem like this almost sounds exact, and now its gone. Is your aluminum radiator vertical? Or better yet do you have a pic? I have some advice straight from the experts at RE, R-magic, Cockpit and my mechanic..

When Im answered, I will fill you in, this is GREAT! If you have an aftermarket radiator and its vertical you know what a pain in the *** it is to get the air out, right?. My air was out after a flush. After filling the air was gone in less then 20 minutes and never had any air problems again. This is the same system used on the aboves race cars. Easy and cheap to install, does require some welding but it will be cheap.

 

you guys are great im check the dipstick 1st
2nd try to burp the thing and should i look for oil in the coolant
or is that impossible.
i have a stock ast and not sure if i changed my thermostat
when i checnged my waterpump and radiator i think i did.almost positive
thanks guys keep suggestions coming you guys are great

 

This what I did to fix the same problem. Remove radiator cap then remove 3/8" water hose at the back of the throttle body. Fill this hose with water untill it comes out cap. This highest point in the system and air gets trapped here. I had to this twice. I have not seen or heard the buzzer in a month now. Hope it work for you.

 

Hopefully you didn't blow a coolant seal.

 

guys i checked dipstick was okay no milky substance.
it was alittle hot today so i went for a drv,when i stopped and
got out talked to friend at shop.got back in car and coolant light
went on again and in 20 sec went off. i drv home about 20 min drv.
got home some anti-freeze was dripping from the reserve tank cover.
was that i over filled it yesterday.i popped hood and ast was bubbling
so was the reserve tank lid when i lifted it off i heard the tank boilling,
after i opened cap and some anti freeze spilled out(threw-up)
i poured new anti-freeze.but **** i only notice buzz when i start car.
and goes away and i drv looking at gauge nothing past middle temp?

 

When you first start it in the morning, look in the filler neck and ast. If you see little bubbles coming up then we might have some bad news for you.

 

MAN IM PISSED AT MY CAR
THANK YOU GUYS AGAIN FOR THE HELP
IM STILL TRYING TO FIGURE OUT THE PROBLEM

 

Coolant seal man, Mine does the same ****. Engine compression is passing into the cooling system causing air pockets that rise to the top whan car is off. Then when you statr the car all the air trapped at the top causes the buzzer to go off

 

well guys its been a month or so and has only done it once
i didnt want to jinx it but by now i think shes back to normal
i hope.thanks everyone for all ure help

 

cool.....hope it stays that way.. You did nothing else to it?

 

checked almost everything my self and flushes radiator
and put new anti-freeze in thats it
im gonna order the pettit ast just in case mines ever goes.

 

have you seen the AST by Fam speed, looks like the original only is polished aluminum...

 

Just for the hell of it try replacing your AST cap. It may not be working right. Or get a friends to borrow, let your car cool down and try it again with someone elses cap to see if thats it(not the water neck cap with the yellow label). I dont mean to rant but get the aluminum AST as soon as possible, its not worth chancing a overheat with the stock plastic one in place.

 

I had the same problem with my 2nd gen and it was the sensor. I am sure the 3rd gen setup is basically the same. so you might try to replace it they aren't very expensive
