Thermostat nipple.

So I checked the thermostat and the nipple in the side is missing.
The question is,should it be there in this application,and if not will it cause overheating?
Any takers.

What are you calling a nipple? I just looked through the parts diagram and don't see what could be missing with out causing a huge leak, other than the gauge sending unit located on the top of the T-Stat Housing.

I think in this case a picture is worth a thousand words.

Thermostat element.

Sorry, I was talking about the thermostat itself not the housing.
The sandwich plate on the thermostat element,has a hole in it with a primitive valve,I've always assumed it was for steam or air to move around the main water tap"thermostat". So if this bead or nipple is missing it allows a small flow of fluid to continually bypass. At a guess over a distance, this could cause temperature to rise. I found one like this in a spare bike I've been fixing. Just wondering what your opinion on it, would be?

I don't think it will matter. I know some will drill a small hole, but on larger cooling systems.
