RE: changing thermostat to 160
I just bought the failsafe from autozone. it was 14.99. it does everything yours does and it also locks into the open position at 180*
ORIGINAL: 2 kwik
the 160 stat can make the car run in closed loop meaning a rich condition..remember some heat is nec. and the stock stat may just start to open at 195..I use only the mr gasket 180 as it's fully open at 180 and has a bigger offic for more flow and also has the small hole in it so you don't have to burb the coolant system it's 8.50 at autozone

There is no reason to run a 160F stat.
Here is an explanation of how hotter is better (to a point naturally).
Everything in the combustion chamber, including fuel, air, cylinder walls, piston, and valves, will take on heat during combustion. The heat is what causes the air trapped in the combustion chamber to expand. The expansion of the heated gasses is what pushes on the piston. If you are putting more and more heat into the cylinder walls because the coolant keeps taking away more and more heat, then you lose power and efficiency.
There are trade-offs. Cooler intake air is denser in O2, but it will soak up more heat energy before it may combust. Obviously running too hot will destroy the motor.
The best answer for power/efficiency is probably the stock 195F stat, but 180F seems to be everyone’s favorite, as a happy compromise.
Also consider that as coolant temperatures decrease, cylinder bore wear will increase exponentially. That means that a relatively small drop in coolant temp will result in much more rapid bore wear.

^^ No they are not accurate at all. Last week I was driving and my temp shot up to like 220... I turned my lights off and it dropped 15 degrees lol
