Drive belt slipping
It is a Mitsubishi motor people just look for tensioner and tighten it a little and on your way very seldom it is anything else with that motor
Sound like a fan belt problem. it may be tight to the feel but worn in the vee groove of relevent pullys. Replacement is 100% fix option just in case it has an incorrect belt fitted .
Yes, the drive belt is the one on the engine that is connected to the pulleys. If it is slipping, then one of the following may be happening (in no particular order):
1) Drive belt is worn. Fix is to replace belt.
2) One of the devices the belt is driving is not working properly and is loading up the belt at rpm changes. Fix is to repair failing/failed component.
3) Belt tensioner is failing to keep proper tension on the belt which allows it to slip. Fix is to replace tensioner.
4) There is some oil or coolant or something somewhere on a pulley or the belt. Fix is to spray belt dressing/belt cleaner on the affected areas.
Try spraying a little silicon on the belt (very very little) it just has to be lubricated, if worst comes to worst here is a link to AutoZone for a list of belts for the make and model of your car. You can choose which belt you would like.
SOURCE: Screeches when turned on and when accelerated it hesitates
Change your drive belts and replace the fuel filter, and air filter.
SOURCE: screech in engine. after serpentine belt stops
Check if screeching is related to engine vacuum.
Briefly remove (or loosen off) the oil filler cap - if noise immediately stops high crankcase vacuum is the cause. Check / replace PCV valve to fix.
If above is not the cause, listen with a short length of hosepipe to try and narrow down noise source.
Silicon lube spray or pencil lead graphite on a selected belt should cause sound change if it's caused by that belt.
SOURCE: screeching sound when i push accelerator then
Likely a slipping belt. Accelerator makes the engine spin faster, which can let the belt slip more. There's a spray product called "belt dressing" that might stop the slipping temporarily - at least long enough to see if that's the problem. Or, you might be able to inspect the belts - with the engine off - and see if one is noticeably loose.
