For the past 3 days when i cold start my 04 g sedan..their has been a high pitch squeak coming from the engine. The squeak goes away after about 8-9 seconds. This coincided with the recent drop in weather in socal 39-43 degree weather for the past few days in the morning time. Their no smoke coming from the hood. Anyone ever experience this issue? I see on my temperature gauge that it takes a little longer for it to get to the middle between cold and hot. I'm doing my 90k maintenance tmrw at the dealership, so I will inquire with them about this issue.

 

Most likely your belts are worn and are slipping for a few seconds.

 

Def belt, or idler pulley issue

 

Mine will do it at way colder temps (5-10*) replaced belts 40k/2yrs ago.

 

Slipping belt. Try tightening just a tad

 

Does anyone have the part number for the ac belt? I have my drive belts replaced a month ago. I believe it might be the ac belt because when i turn on the heat the high pitch starts again. I'm going back to the dealership to have them diagnose the issue.
