Need instruction on changing heater core
2 questions (maybe 3 or 4 
) This is a 1985 Saab 900s. I got it for my niece 2 years ago. The valve for the heater core cracked.
What's the easiest way to fix it? I found an original replacement heater core for $75.
Should I just replace the entire thing? Or can the valve just be replaced?
Also, I'm no mechanic, though I worked at an auto assembly plant for 10 years. I have taken out & installed every part you can imagine on Toyota Corollas, Pontiac Vibes, & Chevrolet Prizms. Wondering if I can replace the heater core with my basic tool set (sockets, ratchet set, screw driver, hammer, buzz saw, etc.. ). Okay, but seriously, I'm trying to avoid taking it 90 miles each direction to my uncles. He would have to come get it (so 4 trips totaling 360 miles). I'm also trying to avoid taking it to the shop. They won't install used parts, & the part they have isn't a direct fit. They'd have to move the gas pedal over an inch at a ct'ost totaling $620. I simply don't have that kind of money for a couple months & my niece is attached to this car. It's the manual transmission IMO.
