....Went and 'returned' the Robert Shaw 330-180 and exchanged it for the
370-180...guess what...there is NO WAY the 370-180 will fit!!...I'm a little
frustrated that the 370-180 stock number kept getting mentioned ( by a
number of members) in the list as the correct one...only to find that it was
not. As I don't think people are lying, is it possible that the 99 V6s DO
have a different size T-Stat???? Those of you who did use the 370-180, what
engine year and size do ya have????
HOWEVER
**The Robert Shaw GT755-180 appears to have the correct dimensions (I
grabbed this one just in case :-))Thanks Ron for the alternate
number!**Strange thing is that U listed this as an alternate if I couldn't
find the 370-180...but these 2 T-Stats look totally different in size &
shape!
The 330-180 and the 370-180 are listed as Robert Shaw "Extra Performance"
T-Stats...whereas the GT755-180 is a Generation 2 T-Stat. From what I have
gathered recently, the optimal type T-Stat would be the 'performance' not
the Gen-2, hence the name :-)
Bernd......as you seem to have a resource for information...is there a
cross-reference between the GT755-180 and a Robert Shaw 'extra performance'
T-Stat??
By the way, here are the dimensions of my STOCK 190 T-Stat:
The flange diameter is ~2" (I used a measuring tape so this is my best
guess)
Please note: The 330-180 and the 370-180 have a cylindrical bottom with NO
spring exposed......this is NOT the same as the stock T-Stat. The stock
T-Stat has the same appearance as the GT755-180, which has the spring
exposed with a "U" shaped bracket holding it in place.
I hope the information I have provided will lead to the correct T-Stat
number being determined for a Robert Shaw "performance" T-Stat. In closing
I'd like to mention a suggestion regarding part numbers on the DML. I think
it is important to mention the SIZE and YEAR of the engine when you list a
part number. I realize we all have a certain degree of common sense, and in
many cases the engine size doesn't matter, but I have seen a number of posts
where people simply list a part number as correct, without realizing that it
may be different depending on year and size of engine. Granted the T-stat
isn't a huge deal...as I could always just get a standard one....but I
believe many (*newbies in particular) use this list as a resource for parts
etc...and I'd hate for us to start loosing credibility because we are
passing along erroneous info, or at least info which is misrepresented. This
becomes increasingly important because we have a whole gamut of Dak owners
GenI, II, III ....oh and the 4.7s who are in a class of their own (not a
criticism :-), if anything I have envy).
...just my .02
