Hello,
Well I have never heard a Motor Mount make a chirping sound. The most it will do is cause engine vibration and may when the rubber is totally gone make a knocking or clunk sound.
There are a few possible causes of the chirping.
The Belt
The Idler Pulley Bearing
or
The Tensioner Pulley Bearing
To test the Pulleys.
With engine off locate both the Idler and Tensioner Pulleys. Then using a spray lube spray the center bolt of one of them, start vehicle if chirping is gone for short period then replace pulley. If chirping still present repeat proceedure on other pulley.
If chirping still present start vehicle and spray lube on belt grooves. Replace belt is chirping stops.
