**Galaxie** · #1 (**permalink**) 04-03-2011, 06:19 AM

I havent had the tstat out of my truck yet. Going to flip over coolant if I get a few other things done on time today.

Is the correct gasket to put the theromstat and housing back on I need just the black rubber o ring?

You don't need anything. Its a reusable o-ring.
Although, I would recommend replacing the thermostat. Ford sells it complete with waterneck and all for around $60

When I removed my thermostat for my coolant flush the o-ring fell out of the groove and seemed to have stretched. I could not get it to go back into the groove. I already bought a new neck and the o-ring is "glued" into place. The old O-ring is also "glued" in place,
