Hi Everyone,

Just wondering if anyone know's the difference between these Tstat's.

RockAuto:
MOTORCRAFT Part # RT1196 {#3L3Z8575AC, 7L3Z8575B, RT1178, YC2Z8575AA}
3L3E-8575-AC; 190 Ex. Hi Temp $9.86

And

AutoAnything:
Hypertech Power Stat Thermostat $32.95

I realize the Hypertech has a lower setting of 160-180 degree (not really what I'm looking for just stock is fine) but that's alot of money...

Thanks for any opinions.

Lou

 

Hypertech is a lower temperature T-Stat, which isn't a popular choice for Ford Motors. Without tuning for it, fords usually run rich with a 160 T-stat so very few people run them. I would stick with the motorcraft, your in for a lot less headaches getting the motor to run right.

 

Thermostats in these newer trucks (vehicles)are touchy. Some open/close in stages, others either open or closed.

Stick with stock. I cant stress it enough. Its a headache you dont want.

Robert Shaw makes a good stock one. If it where me I would get it from the dealer. Or at least see what they are selling.

 

Thanks for the suggestions i'll give the Dealer a call and check his prices

Thanks again,

Lou
