BenKey Posted January 23, 2004 Report Share Posted January 23, 2004 i've also tried this mod more than once, never got it to work properly. I think that there may be different models of the thermostat out there. The bb didn't fit properly into the housing on the one that came off my SS, but did for the one that came off my '99 GMC. So maybe it's just a year or a model thing. The part number may be the same, but the particular one you have could be different, I guess. Link to comment Share on other sites More sharing options...

The part number may be the same, but the particular one you have could be different, I guess. I had almost the same as Ben. The one I took out of my '03 SS would not work with the BB mod. But the leftover t-stat from my '00 5.3L Silv worked just fine with the BB mod. Seems like they have different designs of the piston/shaft that pushes the stat open... btw, I tested both of these in boiling water as BigTex described...

Fun Guy Posted January 23, 2004 Report Share Posted January 23, 2004 What will this mod do exactly? Link to comment Share on other sites More sharing options...
BenKey Posted January 23, 2004 Report Share Posted January 23, 2004 Effectively lower the temp of the t-stat. Link to comment Share on other sites More sharing options...
Fun Guy Posted January 23, 2004 Report Share Posted January 23, 2004 Effectively lower the temp of the t-stat. Right, sorry, I guess I was unclear. What I was wondering was what will a 20* lower temp do for you, and will the effects be discernable? Link to comment Share on other sites More sharing options...
BenKey Posted January 23, 2004 Report Share Posted January 23, 2004 Well, for me, I want to run almost as cool as I can. Heat kills everything and robs horsepower. Being blown and already heating my cylinders up pretty good, I just want it as cool as can be without doing anything negative. A 160* stat will probably only keep you to around 180*. A stock stat, is a 190 or 195, which means temps exceed 200 easily in the summer time. Don't want that. I am more worried about protecting my engine against my driving habits.

Fun Guy Posted January 23, 2004 Report Share Posted January 23, 2004 Hmm, okay, that makes sense. I guess I was confused because I read that the optimum temp for an engine was 180* (anything more or less than that made for a more inefficient motor = less power), so I was perplexed as to why anyone would want that. So if what you're saying is correct, 180* IS the optimum temp, but you need a 160* stat in order to achieve this. Am I understanding this?????

SSMANIAC Posted January 24, 2004 Report Share Posted January 24, 2004 any problems with not getting heat from the heater after installing a low temp stat.? I'v heard that before, but not sure how true it is. Ya know the winters are pretty darn cold here. I don't think this will work for us hunter!! unless we leave the truck running for 45 min instead of 30 min. when is -10 outside like it was this morning the truck kinda have to run for awhile for heat. But who cares it is only GASOLINE. Link to comment Share on other sites More sharing options...
a1cmaw Posted January 25, 2004 Report Share Posted January 25, 2004 the 160 powerstat opens up at 175 (confirmed by boiling water) and keeps the engine at 175 (confirmed by allen nelson's computer plugged up running at operating temp). Link to comment Share on other sites More sharing options...
deezel Posted January 25, 2004 Report Share Posted January 25, 2004 So if what you're saying is correct, 180* IS the optimum temp, but you need a 160* stat in order to achieve this. Am I understanding this????? Yes. The 160* rating means it begins to open at 160. Its not fully open until about 175 or so. My engine runs at about 178. I can tune this up or down at least 5* by adjusting the e-fans controller. With a stock fan, I think you'll run between 160 and 180, depending on the weather...

zippy Posted January 25, 2004 Report Share Posted January 25, 2004 the previous days of a 160 stat though are also different in the location of where the temperature sensor is. the further away the sensor is from the stat, the higher the reading of the coolant temp is going to be which is part of the difference.

deezel Posted January 25, 2004 Report Share Posted January 25, 2004 good point zippy - temp sensor location plays a role too Link to comment Share on other sites More sharing options...
BenKey Posted January 26, 2004 Report Share Posted January 26, 2004 The sensor is located on the drivers side, It sticks out of the head toward the very front above the plug wire. Has a two-wire connector attached. Had mine out a couple of times already. A PITA to find one if you ever break it, unless you go to the dealer.
