It's amazing how much stuff you can find wrong, under the dash and around the engine, when you replace a heater core.

Heat is overrated!!!   The heater core for me is one of the "if it aint broke, don't mess with it" parts.... LukesVette2007-04-09 18:17:56

heat, HEAT? 

Before I get off my sss and investigate a book or two,is the core worked on from engine or interior side? No motor in car,no interior in car,no hood on car.

FUGGEDABOUWDIT! My core was leaking, my buddies 75 was leaking..  We started on his car WHAT A PITA!  My car, we just bypassed it..  I'll never use the heater anyway..

Heat Gooood, Cold bad, Heat give toasty toes.

With an air car, the best way to replace the heater core if you decide to do it is from inside the car.  Remove the dash and the center gauge panel and you will have access to everything that you need.  One more thing.  Remove the right seat.  You will have more room to work.  I highly recommend replacing the seals and the vacuum hoses while you are under there.

I need to replace mine and I live in an area of the country where heat isn't a deal.It's just that I like everything to work.

It was so long ago that I replaced my heater core that I forgot that you don't have to remove the housing under the hood.

On the assembly line they had a frame, a fire wall, a heater core and THEN the rest of the car was put together - built around the heater core!!
OMG what a PITA it was!   BUT.... learned a lot and did a lot while I was there...
