Hey folks, I just purchased an '87 Acura Integra DOHC..the temperature guage hovers at about half way to hot. Is that normal or should I have it checked? What could it be? Also, when I turn on the AC I do not get cool air..it is warm air..could it be the AC needs to be serviced or replaced. Need a few suggestions before I go to the mechanic and have him complete the work...
