I noticed that after driving for about 30 minutes the water in the reserve was boiling, I have no idea what could be going wrong with it.. Also the idle is very high and I am unable to get it to normal, everyone I've asked has no clue on why it does it..

Thnk you in advance :)

could be related.

the high idle could be caused due to a vaccum leak. th is will cause it to run lean. a lean running vehicle will run very hot. this can cause it to overheat and boil your water. check the radiator cap and make sure the fluid is properly mixed.

t-stat could be bad also.
