today i drove my car bout 15 miles (highway mostly) .. when i got to my destination i let it sit with the engine running for bout 5 mins .. turned off the engine and let the fans run .. 5 minutes later it starts ringing .. the water temp buzzer is going off .. i dunno why this is happening .. its about 75 F degrees where im at .. i just upgraded my radiator (fluidyne) .. i do however have a stock exhaust .. my question is why is this occuring? i thought the new radiator would be sufficient for keeping it cool enough .. i noticed this never happening before when i had a apexi n1 exhaust (while running a stock radiator in the summer time) .. is it cause my stock exhaust is too restrictive?

mods:
apexi intake
downpipe
fluidyne radiator
rest of car is stock

 

i wanna kill my ****** coolant buzzer, it is sooo finickey, goes on and off like crazy

 

Do you have a water temp gauge? (the stock one doesn't count)

nope dont have a water temp gauge .. next mod on my list

 

its a buzzer for coolant low coolant level, not temperature. I had to replace my sensor once because it was acting strange as well. As long as you have coolant above the sensor at the filler neck, you know your coolant is not low, and that the sensor is possibly going bad.

 

cool thanks overkill

 

Since it wasn't doing it prior to swapping in the fluidyne, and now it does do it. I believe you have found the source of the problem. The change allowed air into the system. It can sometimes take up to a week or more ( depending how far and hard you drive the car) to burp out all the air bubbles. Just keep checking the level ( when the engine is cool )

if you still need to burp it more you can remove the hose at the Throttle body upper coolant conection. This will be the highest point in the cooling system and help get the air out of the engine or radiator. put a rag under the hose so that when the coolant comes out it doesn't make a big mess. and then smoke making you think you have a leak somewhere

 

good advice .. will do

 

lots of burping... and also check the wire that goes under the alternator to the black plug on the front of the cooling neck... mine completely broke off the harness and had to be redone... the coolant ate it

 

I just finished the hose job today, and started it up and got the coolant buzzer...for the first time in 6 years.
During my work I 'spilled' about a pint of coolant. Oddly enough, coolant spilled out of the upper throttle body hose only when I was pressure testing the pre-control and wastegate actuators.
I am expecting the buzzer to stop when I put some distilled water in tomorrow.
