well I finialy got around to installing my PTE Modded THERMOSTAT, if only we knew what this thermostat was going to do for us,, I would have installed it in the day i got it from Patrick ,, I have not set up the fan mod as of yet but almost don't need it , I am in south Florida where the temp stays above 80 and during the day lately we have had 95 degree temp. and my car stays one notch below the 1/2 mark.normal is one needle above the 1/2 mark being that i do not have the fan mod done yet after an hour of driving (city) my temp. goes back to factory setting,, but wait when the fan mod is in my temp will be one notch below the 1/2 mark all the time. right after the install i drove 62 miles to the track, tecked in and then let it cool,,, temp at the track was 84 degrees,, made 3 1/4 mile runs 12.71,, 12.76 ,, 12.78,, now my temp is comming up,, my last run was 13.01 the thing is this thing works to keep your car cooler and run stronger thanks patrick for this mod. jim

Please tell me about the fan mod and how it is done, thanks, Woody

hope that helps!

 

Put my PTE thermostat in this weekend. A lot messier than the last one I did in a '94 Vette.
I have not driven the car yet, but I have purged the air from the system (per waldig's clamp method and powering the i/c pump) and let it warm up numerous times to check everything.
The temp needle on mine has always resided right above the mid point of the gauge when warmed up. So far, there has been no change in where the needle sits, though I did notice that it takes longer to warm up.
Guess I'm trying to determine if the temp needle should be lower or not. In the Vette, the lower temp thermostat lowered the temperature when fully warm.
Wonder if InMotion can do the fan mod if I send my ECU in for a tune?

 

7/14/09 I installed my thermostat,, yesterday i was with (Wayne LET) and he did the mod on the fan,, My car warms up the the notch before 1/2 this takes about 15 to 20 min in 92 degree weather then it moves very slowly to a needle with below the 1/2 mark it now stays there most of the time,, running 70 on the highway it goes cooler ,,about 1/2 way between the 1/2 mark and the 1/4 mark,, so i am now happy with my thermostat and fan mod.. I will try to get some pic. jim

 

Wayne also included my fan mod when I had it dyno tuned, which goes on when the temp hits 185 instead of the stock 195. What a big difference this has made. My car now stays below the halfway mark where before it was always above during the hot days.

 

mines always just a tad above the 1/2 way mark in the heat. So this thermostat is still set at the stock temp? just has a hole drilled so its constantly leaking some? That sounds like trouble on colder nights you will throw a code, what we really need is a 180-175 factory replacement.

 

The PTE thermostat is not a drilled unit. PTE takes 2 thermostats and makes one 180 degree unit.
I have not driven mine yet, but while idling, it appears to still reach right above the 1/2 way mark on the temp gauge.
True about the cold weather. I only drive mine in the summer so I didn't sweat that too much.

 

I'm not concerned about water temps while stuck in traffic. (day to day driving) I care about the temps at wide open throttle at the track. Even without the fan reprograming, this thermostat will help keep the water temperature lower at speed. Hopefully having slightly cooler water temperature in the radiator will also help the transmission cooler keep things a few degrees cooler too. And my thermostat should arrive today! Any tips that prevent excessive spillage?

With the fan kicking on at 185 degrees, 10 degrees sooner, no one needs an upgraded thermostat. Besides, an upgraded thermostat doesn't seem to work as well. So get the fan mod folks for the best result. Not sure if it can be done with the stock computer software though....

 

with the FAN MOD you will run below the 1/2 mark, and mine in 92degree weather stays a notch below the 1/2 mark for 1/2 hour then moves to just below the 1`/2 one neddle with below the 1/2 way mark and this is 92 drgrees in traffic,, jim

 

I received my thermostat today! It's going in asap. I agree that lowering the temperature that the fan comes on is better in most situations than a lower thermostat, but I think doing both is much more effective than just one or the other. The search is on for a tech that will enable the fan at a lower temperature.

L E T can do it and can put a tune on your car too jim

 

Tell me about it! I want (need) a tune but I have reservations sending away my ECU. The mail to and from Puerto Rico is not the most reliable. But I'm giving it serious thought.

Les

 

find out what a new ecu would cost and insure it for that amount priority mail to let 2 to 3 days 16.00 next day about 60.00 insurance tracking # to amjerry ,, back by the end of the week,, did mine twice so far. list your mods and let them do a good tune on it along with the fan mod. jim

 

i just got mine in the mail today from patrick and can't wait to install it!

only question is, a member told me that i have to take of the belt and tensioner pulley to install it. does anyone know if there is ANOTHER way?.....as my tensioner pulley bolt is stripped and i dont really want to deal with replacing the tensioner pulley right now.

 

Mine will generate sufficient slack by simply pulling on the belt between the upper idler and alternator pulleys.

It’ll slide right off. No tools required.

 

the belt will just slide off? what pulley do you have? ik i can get it to slide off, but with the tensioner pulley bolt stripped, i'm really concerned about getting the belt back on. i have tried the methods stated and they just loosen my tensioner pulley for some odd reason. the 185 is huge and it takes serious cranking on the tensioner to get the stock belt back on

 

I took the idler pulley and belt off. Just used the tensioner to loosen the pressure for removal.

 

yes, i know. but putting the belt back on with the 185 crank pulley without using the tensioner is not possible. it requires ultra cranking on to create sufficient slack to slide the belt back over the pulleys.
