Thermostat Housing Fitment, S4 to S5?
Does anyone know if the thermostat housing from an '88 (S4) can also be used without problems on a '91 (S5)? Are the mounting bolt patterns the same? I want to get rid of this damn plastic one on my '91.
Thanks.
Thanks.

The S5 thermostat housing is made of some composite which, when subject to the high-heat of the rotary, becomes brittle and likely to fracture. As a matter of fact, if it weren't for JB Weld, I'd be in trouble right now.
Thanks for everyone's responses, but I still haven't been able to get a definitive answer. Does anyone else out there know for sure about this housing compatibility?
