Hey guys, Just wanted to post these up.
As we all know both the SVT and Zetec have issues with thermostat housings and after replacing mine twice I did some research and found these and they are a marked improvement.
They're both older designs by Ford, the one that fits the SVT came from an old Contour and the one for the Zetec is from an early production 2000 Focus. The housings are still plastic but it's a denser material and they don't have the bonded lower portion as the originals do that's prone to cracking.
The inner lip that retains the o-ring between housing and head is thicker and stronger and the SVT version also features a screw in sensor and plug which does away with the issue of leaking o-rings.
I've had one of these on my car for several years now without even the hint of any leaks and it's a simple bolt on, plug and play mod.
Here's the pics, This tends to be the primary point of failure on both stock housings,
Stock housing on the left, stronger housing on the right,
Stock on the right, stronger housing on the left,
These are closeups of the SVT housing, the Zetec is virtually identical minus the sensor and plug holes,
SVT kit,
Zetec kit is basically the same minus the sensor.
