The one I have came out of a Stant box #13379 and 195 is stamped on the large flange.
OK great, do you have pics of the two boxes and all the numbers and labeling on them?I just went to advance auto parts and ordered one there. That one looks like josh's stat and I went ahead and did the modification to it and installed it.
The thermostat that doesn't look the same that I got initially I ordered from Rockauto. Aparently there are two versions of the same part number from stant. I'm not sure if rockautos is a newer version or older.
Car stays around 203 degrees. I tried to push it out on the road and I never got it above 204.8 degrees, so it seems to be working according to Ultragauge.
My previous thermostat was an oem one replaced last year and it usually hovered around 180.
Well it depends on how "indirectly" you meanThe oil temp affects coolant temp only indirectly.
In November I towed a 2300 pound load 500 miles with a Mk3 TDI, which had the factory oil cooler. Temps didn't exceed 230°F going uphill. Of course, with that load I wasn't driving 80 mph—55 was more like it.
You might have to try it and see.
Ok that's where I was considering putting one too, what gauge are you using? I am also using the AHU engines btw.Installed a VW sensor "at the engine inlet (post oil filter/heat exchanger)," which is atop the filter adapter on a Mk3 AHU engine.
Cool, thanks!As an experiment I put VW temp sensors in both the filter adapter flange, for oil temp, and in the coolant outlet flange for coolant temp. Ran the outputs of both sensors to a single-pole, double throw switch. Output of the switch went to the input of the MFA of a Mk2 instrument cluster. By selecting the MFA Oil Temp function the readout would show oil temp or coolant temp, depending on the setting of the SPDT switch.
As you said, at engine start the coolant heats much more rapidly than does the oil, and the small oil-coolant heat exchanger warms the oil—good for a cold engine.
After heat stabilizes, coolant and oil temps weren't much different.
I agree about the crummy coolant temp gauges on the Mk3. Mine will show a temp decline on a long downhill run, but it doesn't show an increase on a long uphill climb.
On my Mk3 I also use the MFA readout to monitor oil temp. Have a modified cluster from a V6 car…
I sent the head off to YOU in early 2015! I don’t know if you did mill the head, but said it wasn’t significantly warped. You replaced 2 valves, had some comments on head looking like it had high miles (true) sold me a cam and told me to use a machinist straight edge to check block for straightness. I got Starrett 380-24 24-Inch Steel Straight Edge https://www.amazon.com/dp/B0006J4GKK/ref=cm_sw_r_cp_api_i_QnkPCbFA0045F and I couldn’t get a piece of paper underneath it in any spot with all of the combinations that I could come up with, having the block still in car did limit it some, but I feel ok about it. I used ARP studs to bolt it down which you didn’t really like the idea of, but being a recovering MKIII Supra owner I insisted on.Dremd,
Loose head bolts? That's scary. I bet you have a warped cylinder head.

This fits, even with the added piece on the back?Gates 33209F, Amazon link
This is the [now] 5th mention of this PN (2 or 3 times under Stant) that is also a 195 °F thermostat, and first mention in this thread.
What added piece?This fits, even with the added piece on the back?
