My '91 K1500 noticed a drip from the heater box and having recently replaced the heater core on an '86 I was really afraid to change it. However, GM actually made the swap easy by disconnecting the hoses under the hood, then removing a few 7mm bolts and lowering the access panel, rather than removing the entire heater block. The Spectra Premium heater core is exactly the same as the OEM core, so there are no surprises. Took me about half an hour from start to finish.
