Question about Daewoo Lacetti

Open Question

When I turn on my "Chevrolet optra5 2007 2.0L" the first thing in the morning and when the engine is cold, it gives a noisy sound that stays 20 to 25 seconds then disappears. I park the car after going to work, when I take my break after like 4 hours, the engine gives the same noisy sound again. I changed the power steering pump and the serpentine belt but still the same noise.

Hi , aparentlyyour mechanic just dont want to check nothing else,any new noise should be checked before major damage may happens,the first noise sounds like the new timing belt is rubbing the cover because they removed the alternator and air conditioner belts to install the timing belt ,may be that they did not re install everything right the way it was.......

SOURCE: power steering problem, noise coming from engine, 97 montero

Your experiencing the same thing my 02 is experiencing- your crankshaft pulley is slipping on the crankshaft. It only does it under load, i.e. turning steering wheel(loads the power steering pump) running heater blower on high with headlights on (loading the alternator) or running the a/c with blower (loading the a/c compressor and alternator). Turning off all lights, blowers, ac, etc and allowing the car to idle should kill the slipping until loaded again. This problem is very serious and very expensive if your don't catch it early. It require repairs ranging from tightening the crank to pulley bolt, to replacing the pulley AND your crankshaft if it is allowed to continue. if you cannot get it serviced immediately then do your best to keep loads off of your belts by driving with the blower off, A/C off, and lights used only when necessary. Also try to avoid extreme tight turns which load your power steering pump. Your repair, if not done asap, will cost you upwards of around $3k since the motor must be removed and completely torn down to replace your crankshaft and pulley. I would seek a tech who will exhaust every other method- i.e. sleeving, welding, etc. to effect a repair. Just don't put it off because it will only get worse...

i would check the power steering fluid level. if thats ok. then i would bet its your power steering pump. other possibilities although rare are :
if its power assisted rack and pinion, rack may need to be replaced if its damaged or corroded on the inside. or could be a pinched hose in the power steering hose routing. Wrong fluid in the power steering pump (causing the valves to swell shut) this happens when quick lube places put the wrong fluids in the wrong places. ( i went to one and they put the wrong fluid in my brakes and had to have my master cylinder replaced and brake system flushed... yes they denied it still cost me 350.00) also could be damaged suspension parts causing the resistance to your steering. hope this gives you some leads to find out whats up.

Service Engine Soon Light comes on but doesn not stay on.


If your battery starts turns the engine over, it is doing it's job well. It sounds like your engine computer is not liking the cold engine. If it has been a while since a tune up, it would not hurt to go ahead and do it, but if it runs ok after it warms up, I sould not worry about it a whole lot. When the engine is cold, the egr valve and other things that are made to limit polution tend to stick and give the computer bad readings. A serious tune up may fix it, and I think should, but you MAY still be in the same boat! That does not FIX it for you, but should ease your mind on the light.
