Timing Belt Tension
Volumes have been written on "proper" belt tension values.
Engine Torsional Vibration with sufficient acceleration can cause large speed fluctuations with each cylinder firing pulsation. This results in strong instantaneous torques and consequent belt tension fluctuations. Typical consequences include belt rumbles and vibration.
Accessory system response to even moderate input oscillations can be harsh if a component torsional resonance is excited. Esprit engine is not equipped with a crank harmonic damper. Cams rotating mass in combination with the belt as a spring can vibrate independently of the engine input amplitude with same results as if the engine vibration amplitudes were large.
If belt is not "tight enough" (forgive me for this scientific expression), it'll eat into your water pump inlet hose.
I'd prefer whining of a tight belt!
