johegman Posted February 12, 2013 Share Posted February 12, 2013 Hey guys this is my first post and I searched the best I could but could find nothing. So I had my hood popped and with the keys out of the ignition there was a faint buzzing coming from the radiator area. I open'd the overflow coolant side and the buzzing stopped. What the hell right? Closed it and it started again. I topped up the coolant which it took maybe a 1/2 liter total ran it for awhile and it stopped. I've been loosing a little coolant lately but not a whole lot. I have the X model auto. I'm lost, any thoughts would be great! Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted February 12, 2013 Share Posted February 12, 2013 first thought, maybe a bad rad cap but, more info on the car would be helpful. Quote Link to comment Share on other sites More sharing options...
johegman Posted February 12, 2013 Author Share Posted February 12, 2013 Sorry kinda new to message board stuff. What kind of car info? Its got 160k on the original motor no issues with heads so far. Its the base motor and I just replace the spark plugs and wires. It lost that 1/2 qt of coolant in about three months. Quote Link to comment Share on other sites More sharing options...
yohy Posted February 12, 2013 Share Posted February 12, 2013 Check out this post: http://www.subaruforester.org/vbulletin/f88/noise-back-13202/. According to ferret (#7); "This is common. Remove your grill and unplug the sonealert (beeper). It's mounted front and center to the center upright bracket. Dry out the connector and apply a coating of dielectric grease to it and put it back together.Some moisture, salt ( allowing conduction ) or other matter allowing the water to conduct, gives a low resistance path to the ground. So the sonealert makes a low volume, high pitch noise until the connector drys off again." or this post: http://www.subaruforester.org/vbulletin/f108/hello-help-25903/ again ferret to the rescue: "Look in the manual for replacing one of the bulbs in the headlight. It has How to remove the grill.The 'sonealert' ( Beep Beep ) when you lock the doors has a high resistance to ground thru it's connector from salt and water. It'smounted front and center behind the grill, on the center vertical upright. Simply disconnect the connector, clean it thoroughly, coat it with some Dielectric grease, and put it all back together.Common problem .... IF you have GOOD Young Ears !!!! I can no longer hear the high pitch when someone comes to me with the problem." Quote Link to comment Share on other sites More sharing options...
johegman Posted February 14, 2013 Author Share Posted February 14, 2013 Thanks so much for the info! I really appreciate the help. Thanks again Quote Link to comment Share on other sites More sharing options...
naru Posted February 14, 2013 Share Posted February 14, 2013 It is the Rad cap vacuum valve,not some silly beeper. Why else would removing the cap make a difference? Is it beeping or buzzing? Quote Link to comment Share on other sites More sharing options...
johegman Posted February 18, 2013 Author Share Posted February 18, 2013 It was more of a buzzing. Its stopped now so not sure which it was but we will see when it gets sloppy up here again if it returns. Thanks guys Quote Link to comment Share on other sites More sharing options...
