Running with a 160 thermostat in the summer, you might as well not have one at all, as it will be constantly open, which is not how the cooling system is designed to work efficiently.
Unless you reprogram the radiator fans to go on at a much lower temp, but these engines aren't designed to run that cold.
And if you drive the car in a cold climate with a 160 stat, your (lack of) heat output is going to suck.
Putting in that 160 stat was a waste of time and money.

 

My 95Z has a 180 thermostat and the computer is programmed for the fan to kick on at around 200 degrees. In central FL where summers can hit 100 degrees almost every day and in traffic the temp never exceeds 200. When driving over 30 mph it stays locked at 180 degrees.

There is no need for a 160 thermo or water wetter, or better wetter, or bed wetter or any other item designed to lighten the wallet.

If the car is overheating and I mean actually overheating then fix the problem which is causing it. If you simply want the fans to kick on earlier then get it programmed to do that.

 

I never put in a 160 thermostat, i just kept everything stock as it should be. The car isnt overheating per se, the temp guage moves up to the three quater mark, then back down to half, and repeats this process when idling for long-ish periods of time. im just wondering if its normal for the guage to move passed half way, as on my other cars it never does. the guage never moves into the red zone.

thanks for your comments, ill assume this is normal on these types of cars then.

 

Good assumption, you're fine.
Pardon the Celsius conversion to "normal" temps, but it makes cross-reference easier for the rest of us.
Your center mark (100 C) is 212 F. The next mark up (112.5 C) is 234.5 F.
The fans turn on when the engine reaches 226 F (108 C), and you could still get a little more rise on the gauge before the fans start to bring temps back down. Couple that with the fact that the factory gauges can be anything but deadly accurate, and I'd say you're ok as long as it doesn't go past that mark.

 

Great, I feel a lot better now

Thanks for all your help everyone

 

This site is supposed to be family friendly and here you go talking about getting a "a little more rise on the gauge"

you should be ashamed of yourself

 

bleed it a couple more times and see if that helps. https://camaroforums.com/forum/lt1-l...-system-66742/

 

bahaha f**king lol!

ill give the bleeding another go and see if it makes a difference.
