Need some help with 2 issues...please
 

Hi all, ok i have my 91 non-turbo, ive been fixing the car for few wks now. And now when i fill up the tank, the needle on the gauge goes all the way up, kool, but as the days pass it wont go down less than half tank.

2- change the radiator on the car, replaced the thermostat, replaced the hoses but my heater its not blowing hot.

Thanks in advance

1 check ur gas level float thing haha cant think of the name of it, mine was caught and wouldn't go down the reat of the way.

2 did u flush the heater core? Are the heater core hosea hooked up? Did u put enough coolant In?
