sahouse Posted September 24, 2015 Share Posted September 24, 2015 When I first start my vehicle in the morning, it makes a sound like a coffee percolator (like a chirping sound). What could be the cause of this? Quote Link to comment Share on other sites More sharing options...
mikaleda Posted September 24, 2015 Share Posted September 24, 2015 My first guess would be air in the cooling system. Subarus can be hard to burp out at times Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 24, 2015 Share Posted September 24, 2015 (edited) def. check the radiator level - safely, when the engine is cool. actually look in the rad - don't trust the overflow bottle. not sure from how you are describing the sound - could this be a slipping accessory belt? or, does it really sound like a fluid? maybe open the hood and have someone else start the car and listen. If it's louder inside the car, could be something with the coolant, a/c or fuel tank. If it's louder under the hood, maybe a slipping belt or.....? also, next morning before starting, remove the gas cap. note any pressure in there, start the car.
