i found out that the motor was not in fact hydrolocked. it was a stupid busted positive side battery terminal. once i got that fixed, i drove the truck to work. on the way home, i noticed that my voltage was a bit low and the dummy light came on. i stopped by the local parts house and had them run a quick test. the results were that the alternator was had a low output. while performing the test, i noticed that there was coolant running down and pooling under the truck. upon closer inspection, i realized that the water pump had failed and was gushing coolant out of the weep hole. nice.

i bought a new water pump. i also asked for a new alternator. he had 4 different ones. a rebuilt and a new in 90 and 130 amp each. i originally bought the rebuilt 90 amp. when i got home, i got it all bolted on and hooked up. when i went to reconnect the battery, the terminal started arching and sparking and melting itself to the post. i took it back and demanded that i get the new (not rebuilt) 130 amp. no problems with the install on that one.

my question is;
what is the correct amperage... 90 or 130?
 






The 130 amp came with the Limited models. The 90 amp came with all the other models. The 130 amp can be used as a direct bolt on though.
