You guys are confusing the hell out of me. So is a 160 thermostat bad or good period <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

I've been running a 160 thermostat for about 3 years and haven't had any problems. Then again...it's almost always warm in Arizona.

<strong>The reason is the water was flowing unrestricted thru the radiator so fast that it wasn't there long enough to get cooled down.</strong></font><hr /></blockquote><font size="2" face="Verdana, Helvetica, sans-serif">Totally False! If you slow the water down in the radiator, what do you think happens to the water in the block? The higher the flow, the more heat will get absorbed and dissipated.

Here is a quote from Howard Stewart, of Stewart Water Pumps:

"A common misconception is that if coolant flows too quickly through the system, that it will not have time to cool properly. However the cooling system is a closed loop, so if you are keeping the coolant in the radiator longer to allow it to cool, you are also allowing it to stay in the engine longer, which increases coolant temperatures. Coolant in the engine will actually boil away from critical heat areas within the cooling system if not forced through the cooling system at a sufficiently high velocity. This situation is a common cause of so-called "hot spots", which can lead to failures."

"I proved this to myself after I installed a 160' stat and saw the temp come down a little. I figured if a 160' stat is good no stat at all would be even better. I gutted my 160' stat and put it back in. The water temp immediately went HIGHER than it had originally been with a 180' or even a 195' stat. The reason is the water was flowing unrestricted thru the radiator so fast that it wasn't there long enough to get cooled down. I put the guts back in the 160' stat and the temp came right back down to where it had been"

if you guted an ls1 thermostat most of the coolant wont even go into the radiator, it will just circulate around in the engine. i believe they call this a bypass thermostat(not sure) but when it is closed it redirects the flow right back into the engine. gutting the thing isn't the same as opening it.

I have always heard that not running a thermostat is a BAD idea. Like you were saying, it will actually run hotter.

WS6 RULES

I have a touchless thermometer ( uses laser beam) and aimed it at the therm housing - 177 degrees, the heads - 180 degrees. 2002 WS6 with stock therm.

The engineers at GM put that high temp thermostat in these engines for federal emissions standards. A hotter combustion chamber burns off more pollutants. According to the GM technical papers on Raughammers web site, the engineers came up with a new aluminum composite for the LS-1 block. This new composite is able to withstand greater heat build up. They state this was so they could pass federal emmisions standards and still provide a high performance engine.

As stated bofore in this thread heat causes KR and other performance killing problems. Simply stated a cooler running engine (with good gas)will perform more efficiently.

I have the 160 therm. On the scan master it says my car runs around 178 deg. I also have the fans kick on early.
