I know I didn't have to myself, but some others have had to.

if you go with the 180 stat then no, but if you go with the 170's then from what I read on the board, I believe you do.

Like GodFather said, the 383-180 (180*) is 63.0mm like stock and doesn't need to be ground down. The 383-170 (176*) is 63.5mm and does require some grinding and performance benefits as well.
It's really not hard at all to do, and only requires a few seconds of work on a bench grinder, or a few minutes with a hand rasp/file.

Same here. 2007, Valucraft 4128, needed a small amount of grinding - used my upright belt sander - only took a few seconds. would NOT fit, no matter what I tried, without the grinding.

You'll have to take a number. :p

FWIW, it's the 180 degree stant stat that requires no grinding.

Just put a Valucraft 180 thermostat in 15 minutes ago, P/N 4128. It was def. a tighter fit but it did pop in to where I was comfortable with reattaching everything. Hope no problems occur down the line. Also did the snorkel mod. I'll tell ya, that was simple as can be.

Good to know Drew, because I was a little concerned after I completed the install and read some of this. Phewwww!!! I got the K&N drop in too, of course. Been holdin' back on the B&G stage 2 because of all the discussion of 76% as opposed to more. Sure want the Borla S though!!! I'm thinking that's the exhaust to get. It won't be long time. :)

Wait, maybe I misinterpreted your comment. Did you have to grind down yours?

I know we talked that a 170* tstat would pop a CEL when it is less than 60 degrees...
Would a 180* tstat pop a cel when it is colder (let's say winter months.)?

I have had no trouble with codes running the 180*(winter months or not).

BTW, They are both 63.5mm-- Stroke, Are you awake yet from your self inflicted slap-a-thon, LOL!!

I just installed the Valucraft 4128 and did not have to grind anything. Should I have had to ? Will I encounter any problems? It just fit right in where the stock one was.

Mango the 4128 180 stat is a perfect fit. I installed this a long time ago with no issues. If you go to a 170 or 160/65 stat thats where the grinding is needed. Make sure you have the radiator cap changed to the new one(forgot the name) to keep that perfectly cleaned engine of yours spotless.

My experience with this install is that the 4128 is slightly larger. Maybe its the manufacturing tolorances that cause some to grind and others not to...I drug mine across a flat file while rotating it until it fit. Then I emery clothed the outside edges to get em smooth. Still a bit tight, and I will watch for leaks as this unit will expand when hot. Added Wetter Water for good measue. Will post results when they occur.

Ok, They are both supposed to be 63.5mm. see below

http://www.autozone.com/R,APP83037/vehicleId,/initialAction,partProductDetail/store,1437/partType,00138/shopping/partProductDetail.htm

The overall diameter is 2.52"= 63.5mm

1 inch= aprox 25.3mm....... I guess it really does not matter as long as it works. Since we are still beatin this, I offically had to remove a smidgeon! GC

Yup-it has begun, Andy.
For the results, here are mine-Engine temp has went from 215'ish on a 93 degree day to, if you follow the 15 before/after the unmarked big line between 185 and 215, 200'ish. Very nice. Oil temp was 225 and would go up to 235/240 when running upper rpms. Now, it is a nice 205, rising to 220 when the R's kick in...

I do not think I got "more" power, just able to retain the power I already have. Kinda sorta like when the engine just warms up vs. a hot engine. The "pop" stays with it now, instead of getting a bit lazy at the elevated temps.

Bottom line: Best 15 bux I have ever spent...well worth the time/effort.
