T-Stat question??

409 Views 2 Replies 2 Participants Last post by  sbowling
Just replaced the thermostat housing on my '02 Zetec and noticed that the motorcraft OEM thermostat has a breather hole and the "statin" does not. According to the Haynes manual the breather hole should be oriented up when installed.
Question I have is why the breather hole in the original t-stat and is this important when replacing?

Wasn't getting a response from the other forum...
