How do you change the heater core in a 73 chevy nova?

I%26#039;m having trouble removing the heater box under the dash. I%26#039;ve removed all obvious bolts and it is loose but it still won%26#039;t come off the firewall.|||OK bubba i got you the bolts or bolts u seek r under the hood yes but u can get to the 4 th and bottom one with a 1/4 drive it is at the base of the inner fender so u may have to loosen the bolts to geet to it but i do know that the damn thing wont come out with out taking the bolt out first !some people even cut a small access hole in the inner fender to get to it ?!?!? dont do that the car is a classic so take the extra time to do a job well done!|||You are approaching it from the wrong side.





If the car has A/C and a lot of options, do 1,2,3 - if not, go to 4:





1. Jack up the front of the car and place the car securely on jackstands - do not work on the car while it is on a jack.





2. Reomve the passenger side front wheel.





3. Remove the passenger side front wheelhouse.





4. Remove the two heater hoses from the engine compartment heater box inlet and outlet.





5. Remove the heater box from the firewall





6 Voila - the heater core.|||cdavidbutler2...you sure he can get at it from under the hood?? Oh man if you are right this guy just took his car apart for nothing.





I have done heater cores in Fords before...lots of fun pulling the dash.|||with great difficulty.|||Gosh that should be easy.. through glove box? bolts down side of it??|||This site has lots of info. If it does not help you might consider getting a manual, they are life savers!


Good Luck!|||Buy a shop manual, numnuts!|||check the cable to the heat to make sure it is not in the way becouse it can be get held up|||I have not done a 73 befor but the last one I done was sealed on with sealant or a gasket of some type after all mounting hardware was removed for sure like the screws ariund it and the hoses off use a tool like a putty knife or thin wide blade two seperate from firewall should work .
