Cold start noise

[Namemaker]

My 1998 Continental makes a noise during cold starts that sounds somewhat like the starter is not disengaging. The noise lasts a few seconds longer the colder the outside temperature is then disappears unless engine is revved. The noise completely disappears once the engine is warmed up. Thinking it was a starter issue I put a new one on, but it didn't change anything. Then took it to a local mechanic who I trust and also the Lincoln dealer. Both thought it was a vibration (resonance) coming from the power steering line (apparently there is a TSB out about this) and both said the cost to fix it wasn't worth the money unless I couldn't stand the noise.
Has anyone else experienced this? Is there anything else I should consider?
Thanks for any insight you can give.

The sound you are hearing does it sound kinda like a squeel?It could be a loose or worn belt.Possibly a bad bearing on your power steering pump or altinator maybe.The best advise i can give is to check all the simple easy to fix things first.

Typical Low-Speed Vibrations (Less Than 72 km/h [45 mph]):

• exhaust vibration
• engine harshness/vibration
• power steering pump vibrations
• drive belt vibrations
• engine cooling fan vibration
• take-off shudder (excessive CV joint operating angles or bad CV joint)
• brake roughness or harshness
• driveline roughness
• excessive wheel runout
• tire flat spots
• components/material trapped between the body and the frame, the engine and the frame or the engine and the body
• automatic transaxle clutch slippage

Typical High-Speed Vibrations (Above 72 km/h [45 mph]):

• excessive tire-wheel and brake disc imbalance
• tire roughness due to high non-uniformity (force variation) or out-of-balance condition
• excessive tire and wheel runout
• components/material trapped between the body and the frame, the engine and the frame, or the engine and the body
• worn suspension components
• front end accessory vibrations
• exhaust vibration

• Power Steering Pump Noisy

• Low fluid level and possible leakage.

• REFILL to specified level. REFER to System Bleeding in this section. CHECK for leaks. REPAIR and/or REPLACE as necessary.

• Plugged reservoir filter.

• REPLACE the reservoir; REFER to Section 211-02 .

• Power steering pump.

• REPLACE the power steering pump; REFER to Section 211-02

• The Generator is Noisy

• Loose bolts/brackets.
• Drive belt.
• Generator/Pulley.
