screech sound comes when i start the engine in the morning for 30 seconds

Sounds like the belts need tightening or replaced

Though this only happens in the MORNING SPECIFICALLY. Later during the day, when i start the engine the noise disappears

If it go's away,most of the time its the belts. Leave the engine off pop the hood,look at the belts do they look worn split or frayed. Next morning pop the hood,start the car and verify that its coming from the belts. If so have them tighten or replace them. To keep it cheap get the belts from the dealer and have someone put them on for less money.Labor at the Bens dealer will kill you.

yea could be that too

ill try that i recorded a video of it. If i can forward to anyone , please availe ur email #

Save even more money and buy the belt from a car spares shop cos they usually sell oem stuff a lot cheaper than the dealer, next in the grand money saving scheme, fit the thing yourself! Look at the engine, draw a diagram of the pulleys and the direction of the belt. Now just locate the belt tensioner, slacken it off and swap the belts. Tighten the tensioner tight enough that the belt won't slip off the pulleys and give her a whirl.

anyone have an idea on my Mercedes c220 sportcoupe, when i start it in the mornings all lights works but the engine doesn't take power for some minutes, after some three or four times try it starts normally till the end of the day without . but the problem repeats every morning over and over it sucks, if you have any idea please help.

you need to lubricate the engine belt with DOVE ,SOP not for your shower only , we use it to see,, if the sound comes from the belt or the dolly belt may it help watch your fingers please/// abdull best regrades

I have learned from haynes manuals on my benz. It took 7 manuals of various types to find the belts tensioners and pulleys that are actually used on my car, But a call to autohaus for belt parts before correcting the tension just took 3 minutes.
