Broken Thermostat Housing

[scorcher1967]

So, I pulled the accessories off the motor to paint it, stripped a couple threads on the intake manifold, argued considerably with the emissions assembly, but all came off clean until......

Both upper bolts snapped inside the housing. The passenger side flange snapped off, and there is a fracture through the passenger side bolt hole.

Being of a mostly Ford mind and spirit, I don't know if this is a common problem on pigs, and if there is a way to prevent it. The fracture through the bolt hole looks to be from a PO over torquing. But snapping both bolts on the thermostat? In aluminum? Ideas? Anyone got a good replacement piece?

Should be an easy find! If you can't find one let me know 'cause I'm not using the "F" engine that was in my '67 FJ45LV and the parts should be interchangeable. You'd need to wait till I'm stateside though.

I would start using a torch and a little heat for the rest of them. Maybe somebody used loctite.

basic electrolosis(sp) steel fasteners in aluminium, different metals. anti sieze is your friend.

if they were overtorqued, I would think the threads would have pulled out of the aluminium

They did pull out of the intake manifold. Simple tap and rethread there...

I've got a housing that looks just like that. Broken in the same area. Anti-seize is your friend.
