Hey northeast jeepers. How are you all? I got a issue with my 1997 jeep grandcherokee. Ill start from the beginning, around this time last year i replaced a leaky radiator and serpentine belt, belt was worn and easy access with radiator out so i replaced it while i was in there cause the trucks belt squealed everytime i started it. New belt still squealed replaced alternator squealing only happened if i turned my radio up over 30. (got a kenwood headunit and a 2channel amp that draws alot) so i added a 2.0 farad cap to keep the charging system up over 12volts. Had no issues at all with the noisey belt till i parked the jeep at the end of september, went to start about 3 weeks ago and battery was dead, charged it up started truck and altenator wasnt working. replaced negative battery cables but broke the stupid tiny studs that the wiring harness attaches to the altenator with. Went to autozone and with a little convincing they refunded it, put the brand new alternator in and adjusted the belt so it has maybe 1/2 of play. now when i start up the belt squeals again. usually stops within 5 min of driving sometimes right when i engage out of park into DRIVE but i notice my voltage is down around 10volts when it squeals so my altenator isnt working? or its slipping on the pulley? even if it stops itll start when i turn my radio up above 30 again. on colder days the sound takes longer to go away and sometimes comes back when im turning, only if its cold though. some people said just spray some belt dressing on it but id really like to know if there is anyway to check the belt for tension.the idler pulley has very minor pitting on it, water pump works fine, ps pump works fine (if sound stops and i turn wheel sitting still it doesnt squeal) it is alittle tighter on the side going from the AC compressor down to the altenator then it is on the top between the ac nd powersteering pump. not much it only moves maybe 1/8th of a inch more. altenator brackets are tight as they get. sorry if this got too long winded but im trying to cover all the bases, looking for any advice or a shove in the right direction, thanks.
