No heat for now - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I just unhooked my heater core hoses and connected them together. I had a leak last March and did a quick fix as I was working pretty steady, no time to monkey around, so I dumped a bunch of Barr's Leak seal in the rad. It worked up to now, leak is back. So I was wondering how specific are heater cores for my 1970 GMC? I have the opportunity to pull a free one from a 1977 Chev truck, same animal? or different?

Different, I believe. A core should run you about $50, IIRC. Careful, though... my core was a full 1/2 thicker than what all of the parts stores carried. I had to have mine re-cored at a cost of about $85.
