engine squeeling after swap back in

[jt15833]

i took my motor out to replace the oil pump and after putting the motor back into the car it squeels pretty badly. only accesory belt on right now is the waterpump and alternator belt. im leaning that its a belt but maybe something else. any ideas?

does it sound like beltS????

check belt deflection, if its loose, tighten. If it doesnt' deflect at least a half inch or so, its too tight and its probably your bearings in the alt squealing and it will burn it up if you don't loosen it.If neither of those help, spray some belt dressing, if it goes away its belts, if it doesn't its something else. also helps to put your ear to the end of a piece of pipe, you will be able to localize the squeal.
