I can't find anyone who sells the 180 degree thermostat for my 1993 Mark VIII. I have tried: Napa, O'reilys, Advanced Auto, Autozone, and the local Ford Dealership.
Does anyone have the part number for the 180 thermostat? Or know where I can get one?

Just get the MotoRad 160 by Hypertech from Summit for $21.50.
 
I used the Napa 180 degree thermostat they have listed for a 96 Cobra. Worked great... Also I like the Motorcraft 180 degree thermostats.
 
why do u guys wanna run a 180 degree t stat? you trying to dump more fuel? just currious.
 
You don't "dump" more fuel with a 180 degree thermostat.
 
a 160 you will, but a 180 you wont. a 180 (with a factory stat of 195) will increase power, if only minutely

Now Andy how do and why do you "Dump" more fuel as you say? You have been in my car all day and I have a 160 tstat and have had it for 7 years. Was I "Dumping " fuel? in fact we were getting 27.5 mph at 75 mph.

You will NOT and do NOT "Dump" fuel with ANY tstat.
 
Come on guys, I'm sure you all know that a 160 or a 180 degree t stat will cause a computer controlled car to run a bit richer, maybe not dump fuel as I said, but it does cause it to run richer.

I have had the Snap On MT2500 hooked to my car both prior to and after installation of the 160 and there were no changes except the actual coolant temperature.

Remember these are rated T-stats and they never actually make the car run at the rated temperature. Mine with a 4 core NASCAR Griffin Radiator coupled with the 160 still sits at 185ish.
 
its an urban legend that a efi car will run rich with lower t stat,seriously,the sensors controlling engine air/fuel mixture dont care what temp the coolant is,they are measuring incoming air temp,not engine block temp,i read somewhere a few months (a year maybe) ago that t-stats causing rich conditions is one of the single biggest misconceptions about electronic fuel injected cars and their relationship to modifications(like lower tstats).
 
I run a 160 Tstat with a cooling fan bypass and digital controller. On the highway it never has any problems running 'too cold' or 'rich'. With the 'switch chip' I even run the stock program.

At the track I switch to bypass the VCRM control to the digital controller which is set to turn the fan on max at 180* and turn the fan off at 165*. This is with the 'dynotune' program or 'race' program on the switch chip.

By replacing the 195 with 160 it could result in it running it a "closed loop setting" hence running richer. That theory only is logical at startup. Basicly its just running through the closed loop a little longer, but not consistantly. Also, them 4.10's help you get that motor nice and warm and cozey. I retract what i previously said. It is just "dumping" more fuel than needed only on startup cycles.
 
Other than the friction of the T-stat and housing, the T-stat has nil effect on the normal operating temperature of a properly sized, properly operating cooling system. The stock fan on these cars do not come on until 215* and turn off at 205*(without the AC on). So in theory, normal operation will be start up, engine warms up, Tstat opens at 195*(stock), engine continues to build heat until one of two things happen. The radiator is removing heat at a pace equal to the engine making heat or the fan comes on to assist the removal of heat through the radiator. IF during operation, the operating temperature drops below the T-stat temperature, the T-stat closes. Suffice to say IF this happens, the engine is not operating in it's normal environment.
 
So does anyone know the part number for the 180 thermo. ALL of my local auto stores WILL NOT HELP w/ out the part number.
 
They don't need a part number. If they tell you they need a part number they have poor customer service and I wouldn't do business with them.
