Stuck trying to replace heater core '94 Sub.

[davek]

I've always avoided this job but, I gotta go to Florida in this land yacht to pick up a boat. It's uaually used just on ocassion and I hope it makes it. Again it's a '94 Suburban and the manual says remove screws from engine compartment. No pic so, I see 2 on the fire wall in the middle just below the air cleaner. Does anyone know if those are it and the only ones involved. I'll mush through this over the next day or so. I love that smiliy face.

Thanks for any help!
