I'm replacing my stock lower T-stat housing (threaded sensors) with RH144 housing (clip in sensors) and RG614 (Motorcraft #) lower T-stat housing gasket. Ford pn of this gasket is 1L2A-8255-AA.
Difference between RG614 and stock gasket is significant. Stock gasket is about 1/8" wide and 1/8" tall (i.e. square profile). It has more way more contact area with block than RG614, (Ford # 1L2Z-8255-AA):
I'm skeptical this new gasket will adequately seal against block top. Don't ever want to do this job again. Would love to hear from those who've replaced their threaded type lower T-stat housing with the RH144 housing and RG614 about longevity of their repair.
EDIT
Also, my RH144 lower housing has a slight rattle when I shake it. Like a small plastic piece is loose inside. Spent 30 minutes trying to find what causes it but found nothing. All bushings are tight in their bores. Housing is stripped (no sensors or clips or thermostat), so nothing else can be rattling around.
Is this a check valve inside the body?
