I have a 02 lancer and ever since i had my belts changed (alt and timing). I have had a very loud squeal when i start my car sometimes. Generally it has to be a little damp out like dew on the grass. Any ideas i added new PS fluid and used the belt spray. The belt spray works for only the first startup. Any help would be great. Thanks

Just for testing, a few seconds, will the vehicle start and run w/o the belt? Have a helper work the throttle, is the sound gone? If problem not the belt, check the belt driven accessory. Sometimes you can use a long metal rod of some kind, with belt on, one end of the rod touches accessory housing, the other end goes on that bone behind your ear, helps to magnify the sound. I guess you could use a mechanics stethoscope to do the same thing. Have helper work the throttle while you listen to each. Don't get tool or anything caught in belt. This is a serpentine belt, I haven't looked?
Maybe an accessory trying to freeze up or bad bearing? I can't think of anything else at the moment?
i checked the engine at gates.com, a manufacturer of timing belts. the '02 lancer is listed as an interference engine. that means if the belt broke while the engine was running, you might have some damage to the valves. also if it is slightly out of time, the problem could occur. you must make sure the timing is spot on, which may require going back into the timing belt and checking crank and cam position. you may also have to tear the valve train down and check for damage
Shortly after replacing the serpentine belt in my lancer, the same thing happened. It is NOT the timing belt. Belts squeal when they slip. If your timing belt slipped it would cause your car to run funny.
have somebody check the belt for wear (or do it yourself), replace if necessary. If it doesn't need replacement, just tighten it.
If you have the 4cyl engine that I have, the tightening is kind of a pain in the ****. Not a great design by mitsubishi. There's a pulley near the front right corner of the engine in front of the alternator. the belt should be running around this pulley GROOVE SIDE OUT. This is the tension pulley.
To tighten: 1) Lightly loosen the bolt in the center of the pulley (slightly loosen, DO NOT REMOVE). 2) Under that pulley there's another bolt. You can see that the bolt goes through a piece of metal attached to the back of the pulley. Figure out which way you need to turn the bolt to move the pulley toward the front of the car. (i don't remember if it's right hand thread, or left hand) This puts extra tension on the belt. You probably don't need much. Over tensioning the belt can cause pulley bearing failure. If you haven't done this work before, ask someone for help. It's better to tighten a little bit, a few times rather than overtighten once. 3) Don't forget to ReTighten the bolt in the center of the pulley.
If there's lots of cracks and pieces missing on the ribs or grooves of the belt you should replace it first.
Belt turns alternator, alternator charges battery.(no belt, no charging) Charge battery with a charger. Though it may start with a jump, the alt is designed to maintain the state of charge in the battery, not to fully charge it . Therefore jumping puts too much demand on alt and can damage it. or will shorten battery life considerably.
