Coolant tube bolts - ZR-1 Net Registry Forums

VetteMed · 07-13-2010

I did a big no-no when disassembling mine, but it worked out OK in the end. I used a thin-bladed screwdriver as a wedge to try to separate the coolant tube from the IH. Also, I used a dremel with a cutoff wheel to attack the bolt shaft from the tiny gap where the gasket sits. It was enough to allow a little more angle for PB Blaster to work its way into the rusted areas. Far from ideal, but it worked in the end.
