I know, , experience talks.
we buy new belt and the clerk gabs abox
1: wrong belt in box, last customer returned it like that.
2: clerk gave you wrong box used wrong engine table(GATES)
3: you told clear wrong and he did it wrong.
4: learn that some engines even same 1.6L displacement had 2 head types that year. or series of years.
my car here, has 3 belts sold for it, 2 are wrong, per above.
no belt brand told just 164 code (gates?)

OP never told it is a toyota , nor the year, wow no year.
3s-fse =1987 to 2000 year made. no car model told what can go wrong, answer ALL. that.
DOHC engine 2 cams. CR = 9.8 (3S-FC, 3S-FE, 3S-FSE)
2.0L engine 1,998 cc, 121.93 cu-in
step one make sure both belts new and used, laid top of each other have same number of teeth and pitch. (viewed) if not WRONG belt.
OOPS? (the new belt can be touch tighter.,old belt stretched be longer or even a wreck)
some models have VVT, in the head and may change the T belt USED, no car told no year, no VVT told.
1990 turbo?
1990 camry is gates T138
1990 turbo T125

if you buy a belt for the wrong 3s-HE engine you fail
learn what is there, first, under hood. exact engine
turbo or VVT or what, make and model and year not old.

we can only beg cars model.
Toyota Avensis (T220) Toyota Celica (T160) Toyota Celica (T180) Toyota Celica (T200) Toyota Camry (V20) Toyota Camry (V30) Toyota Camry (V40) Toyota Vista (V50) Toyota Caldina (T190) Toyota Caldina (T210) Toyota Carina (T170) Toyota Carina (T190) Toyota Corona (T170) Toyota Corona (T190) Toyota Picnic (XM10) Toyota RAV4 (XA10)

check rpm whithout the ac if its the wright rpm.
ac uses also rpm .so when its whithout allreddy stalling ,it will for sure ,when you turn on ac.

could you give me more info on the car itself. What year model is it how many miles??

you should check fuses first if its been working good then i would dought if fuse jumped OUT of fuse box , there is a fan relay also , could be bad . swap out relay with a good one see if it works. you can also check temp sensor that tells fans to come on . good luck .

Did the problem start after the alignment?Sounds like a lack of caster in the alignment.

what the timing mark setting 10 or 11, 12 for engine running system 3s st171 engine 2.o petrol toyota corona

sounds like its starting to slip have it tested at a transmission shop

Most auto parts stores like NAPA will have this item
