Is the Thermostat Supposed to Have a Rubber O-Ring?
1991 305TBI
I bought a new Thermostat housing with gasket and a new thermostat.
The new Thermostat does not have a rubber o-ring around it. I watched some videos and it looks like some thermostats have the rubber o-ring and some don't.
Is the TBI thermostat supposed to have an oring around it, or does it just sit right in the groove without one?
