i need to know how easy it is to re-hook up my heating system. i have never had heat since i bought the car 2 years ago and kansas winters are not that brutal so i could put up with it and i just moved to PA for college and it sucks the winters are brutal i believe my heater core is still good i think all i need is 2 lines but im not really for sure some pictures and directions would be great!!!

Thank You

I’ll assume that when you say you think all I need is 2 lines that you’re referring to the 2 lines from the heater tubes
to the actual heater core tubes
?

If you hook those 2 lines up and find out your heater core is "not leaking" (again I’ll assume that was the reason the 2 hoses aren’t hooked up to the heater core was because there was a leak in the heater core) then I start looking for potential vacuum leaks.

From the large vacuum T on the driver’s side on the firewall
you should have a vacuum line that goes to a check valve near the passenger side hood hinge
,
the bottom line goes into the inside and behind the heater and the other line goes to a vacuum reservoir under the passenger side fender
.
Make sure these lines are not cracked and operational. From there it’s a process of checking all the vacuum line to make sure everything is hooked up to the different vacuum motors.







Hopefully this helps?

If the heater core has been disconnected, I am betting it is going to leak if you hook it back up. That is the quick easy fix for a leaking heater core is to disconnect it. They can be really a chore to replace, and I have only replaced one and that was in a Ford Fairmont. It was an all day job nearly as the dash had to come out. If you hook it up, keep a very close eye on your coolant level, and watch for leaks. You can likely smell the anti freeze leaking inside the passenger compartment. Good luck.

now if it leaks will it drip on the floor board or from the engine compartment on the ground?

Usually the first indication of a leaky heater core is the smell of anti-freeze, or when your front window fogs up followed by water/anti -freeze on the carpet.
That usually seems to be followed by anti-freeze leaking through the plastic pipe in the engine bay.
