Hello everyone,

I received a few PMs awhile back regarding PTE t-stats. I reached out to PTE via MBWorld, and he can do a production run of t-stats towards the end of this month (May 2009). Normal list is $140, but he would be able to cut that to $110 for a Group Buy.

As has been known/evident on MBWorld for quite a long time, Patrick (PTE) is a stand-up guy, and makes a high quality product. To my knowledge, these are reengineered t-stats set at 180*F, to aid our engines (especially the modded/overboosted ones) in running a bit cooler. I have one of these NIB right now, waiting to go into my C32 later this spring/summer.

I've asked PTE to create a username over here, and post up some additional information for your benefit. In the meantime, it might be helpful for him if a list is started to gauge the overall interest level in his product.

Thanks - hope this helps out for those of you who wished for additional info.

 

i'll take one.

 

Interested .

 

Look forward to PTE joining the forum and discussing his product.

If he is replacing the OEM 195*F wax pellet in the thermostat with a 180*F pellet; and not just drilling some holes or wedging the thermostat valve partially open - then I'll be interested.

I think the climate in my area is such that the normal operating temperatures of my engine coolant is almost always going to be above 200* F.

A 180* thermostat would open up sooner and prolong the warm up-time to normal operating temps, but not reduce it.

Perhaps if you live in a cooler climate this will be a great mod - but in winter months, your cabin heat may be reduced.

 

I would be interested also.

 

I'm interested, but skeptical. $110 is a lot for a thermostat.

 

Brian he doesn't drill holes it is a new thermostat made from tow different MD ones. Dave

 

It is made from two seperate MB ones, check the price on a factory one $110 group buy is a excellent price.

 

Remeber to receive full gain from this mod you should have your cooling fans re-calibrated.

 

Didnt you say that can only be done by LET and in person with the car there?

 

Cooling fan -10*C mod can be done by any shop that has access to STAR diagnostic software, and the appropriate know-how to assign the correct changes. Jerry posted a very informative step-by-step thread on MBWorld with the exact order of steps in the C32, C55 AMG forum - a search over there would probably turn it up.

 

Yeee-ow!
$110 for a thermostat?

Maybe we can get amx1397 to make one for free out of a bottle cap!

 

I ordered mine today,, I willk take pic of everything when i get it ,, jim

 

Correct......

 

LOL your funny, but i might just try that,, but then why when PTE is less than 50 miles from me in fact he is delevering my thermostat to me as he told me he has to go to miami and will be within 5 blocks of my house so he would drop it off. and i am going try to talk him into going to the track with me,. here is the pm i received from Patrick. ,,,jim

Good Morning Jim:
The parts come in from Germany. I hand build these Thermostats in my small machine shop . Even though they are called 160* They actually bring the engine temp from 210*F / 100*C too about 180* F . The 160* one , which I don't build ,would set a CEL on cold nights. Thanks for your inquiry. , Patrick T. Eves

 

That's about right if he has to purchase two t-stat's to make one.

 

For those that are interested, I made a 172 and 180 version using stant superstats elements.About $30 or so, details on a posting that I did...........

180 is as cold as you can go, in Northern Va I throw codes at 30 degrees because the engine does not reach normal settings and MB is watching out for me,,,,,,,,,,,,,,,,,,,Yawn. I do not have fan speed settings changed, to do so would possibly make that an issue at even higher temps.

180 degrees is good heat for the cabin, no issue here at 20 degrees, american cars had 180 for a long time, 190 +++ is for emissions only and not the power or heater reasons.

Enjoy, and some one will show my thread soon enough, for the simple up grade, Id get a spare tstat body and mod that so that you can change back when you want or sell or what ever if your in NDakota...............

How about that stock market today, hot damn makes my week................W DY

 

im all for a cooler stat, we have been playing with the one out of our spare motor, it is stamped 87C which is 188.6F, are you saying yours is a 195 stat (90C)?

we see 198-202f on our car durring normal driving, i havent pulled that stat yet to check what that one is stamped, maybe the one from our spare motor is different?

 

That's the temperature specification they SRT6 Service Manual uses for testing the Thermostat.

I did find a 187* Thermostat at a online parts dealer for a C32. What car was your spare engine pulled from?

 

srt6 engine, hmm crazy, ill have to pull the one in my car and possibly switch them out of thats the case, has anyone ever pulled theirs to look?
