Hi, I have a 96 GLE with almost 140,000 miles. Lately when i start it up cold, I hear a sound like a belt slipping or something for about a second..then just normal engine noise. this does not happen when the engine is warm, only cold start-up. Does anyone have any ideas?....the car runs great otherwise.

 

the belts get harder in the winter cuz of the cold weather from what i know, its normal if i was to guess but im not sure

 

i have read somewhere else in here about timing belt tensioner....would this make a noise like what i described earlier on start up?....looking for any answer

 

is it more of a whizzing sound than a squeak from a belt? if so, it's your starter sticking.

 

on every car iv owned and driven iv eventualy had this problem :P i thiiiink its just cold belts. if you tighten them too tight though it could be bad. i think it's normal, but im no expert

 

hold your key in the start position for 1 more second on a cold start to make the noise go away.....it is your starter sticking, I think it's normal...in cold weather...

 

turn your heater off when you start the car.... I got the same problem... but when the heater is off it goes away

 

it's not your timing belt as our cars don't have a belt they have a chain so if it's not a chatter type noise then you can eliminate the timing chain, most likely is a belt, see if it persists when the weather warms up, if so get someone to help you locate it and either replace or tighten. Doubting it's the starter itself they make a whinning noise but consistantly regardless of engine temp, not just on cold start up. Could be your alternator belt. Good luck.
