heater core

i have a 1990 z24. i am replacing my heater core. can anyone help me with the eaziest way to remove it? i understand i have to remove the dash, i'm just not sure how. also i am removing the core from a sunbird and not sure how to remove that dash.

Well I don't have a 90, but I recently worked on my son's 93 Cav. To get to the heater core I did not have to remove the dash, just the glove box, some duct work, and the driver's side under-dash cover (plastic piece that fits around the foot pedals). At first I just tried to get to the heater core cover. I sooned realized that it would be easier to just get the glove box out of the way. I'm no mechanic but after a couple hours I had a new, fire-breathing heater core. Putting it all back together was no big deal after learning how it all came apart. Good luck!

thank you replying gwinters, I actually bought a 93 sunbird and started to take it apart and the first thing i did was the heater core. so i now have a new warm z24. my wife says the heater is so hot that it burns the hair off her legs, so now she seems to want to drive my car a couple times a week.
alot of the parts from the sunbird are the same as the cav, there is a web site that i cross reference the part numbers on.
thanks again for the reply...later.
