After I installed my thermostat I read where the pin on the thermostat should be in the 12 oclock position. I just slapped the thermostat in place and bolted the housing.
Having the jiggle valve at the top of the thermostat allows any trapped air to escape. If there is an air pocket trapped behind the thermostat, it may not open.
on my civic there's a spot on the thermostat housing that allows for the pin to "fit in" upon installation. applying otherwise might not guarantee a tight seal. yours seems to have a different design. +1 for erik's comment. nike: just do it.
What hacks me off is that if the orientation is so important (which I understand now that it is) then why aren't there any instructions in the thermostat box?
Linear Mode
