every day when i start the car in the morning i hear a chirping noise coming from the timing belt area. when the car is warmed up it goes away. or when i accelarate no chirping. strange!
Chirp during cold and/or first start of the day. Improves with acceleration. No relation to steering. Resolves after 10 minutes of driving.
I had my timing belt changed along with the water pump. i have noticed this chirping noise every since I had these items replaced.
constant-squeal/squeak--when engine cold. dissipates immensely when engine warms// i replaced o ring ($2.55)//part on one of the power steering hoses// noise basically quit! but now iam concerned about this idler issue?
I just had my water pump replaced on 2003 accord 2.4lt. It has 256,000 on it and this is the 3rd waterpump thus far. The best is and was working fine until I got the car back from the mechanic. Now it chirps until the belt warms up approx. 3-5 min after first start up. I think it is either alignment problem with new pump. Mechanic is going to try to scuff up the belt - he thinks any coolent on the belt or pulleys while changing the belt might have glazed the belt. we will see.
Idler Pulley makes a vibration noise when you step on the gas. Wonder how much it costs to fix it??
new idler pulley had to be installed
