Thermostat Question

Recommended Posts

I've obviously stripped a lot of bits from my 2L Zetec Blacktop acquired from GBS when I bought the kit. Things like inlet manifold, exhaust etc.

 

One of the things I came across the other day was the thermostat housing from the Zetec. I retrieved the thermostat and noticed that there was a small hole in the housing with a tiny bearing and holder to make what looks like a non-return valve.

 

Given other peoples advice on this forum regarding the problems with the Raceline water rail, which I have fitted, would my water rail setup benefit from a similar type of thermostat instead of the supplied one?

 

What is the effect of having a small valve like this in the housing?

 

Thanks

Luca

the hole is to let the air escape when filling with water

On my Pinto I did not have the small hole so I drilled one.

It can help with air lock problems common in 7's

I was wondering more about the non return-valve part of it on the Zetec thermostat.
