Help!

1. battery want stay charged/alternator wont charge the battery
2. my engine temp is running at 205
3. ac compressor squeaks bad when activated
4. whole car vibrates bad

check the wiring from the alternator back to the fuse box and then back to the battery.

temp looks fine. are your fans coming on?


also check simple stuff like the belts and pulleys...hard to say what it could be without looking at it

Sounds a lot like a belt/pulley issue. It'd explain the first three issues, possibly the last. If they routed the serpentine belt incorrectly, that would explain your electrical/cooling issues. They may not have tightened all the bolts down somewhere, which would lead to the rattle. I'd start by looking there.

number 4 is fixed but not 1-3 what couls it be? also at the back driver side of the engine where the radiator hose connects there is a cone thing inside (forget the name do to stress).. does the cone face you or no?

btw battery light on dash stays on and i looked it up and says wont stay charged...

deff a belt/alternator issue, check you're fuses to start. Then the connection between you're fuse box battery and alternator.
As far as the temp of the coolant, mine doesn't ever hit 205 when driving.. maybe at idle but i usually run around 185 but I'm blown so its a different story.
Self install or did you take it to a mechanic?

even if it hits 250 degrees your still fine....

now for No.1 have you checked the wiring from the alternator to the starter to the fuse box and back to the battery? is your alternator good, have you checked it? see how many volts its putting out...its should be putting out around 13.5-14.5 volts

and No.3 might be a bad bearing since your putting a load on it...you say it only happens when you activate it, it squeals so it could possibly be a bad bearing. dont activate it and your ok...lol

just cuz it looks good doesnt mean it is...do a voltage drop and see if you have any high resistance through any of the cables
