  • 160 or 180 thermostat on a 3.4

    Any advice on the better thermostat for a 3.4? I've heard that the 160's cause too much variance in temperature considering stock is 195, which is bad for the engine. Which gives the better performance increase?

        the 160 may cause computer problems, and it will take a while for the heater to get warm if thats an issue

          if the 160 can cause computer problems, would that also be a problem with the 180?

            see im trying to figure if the 1608 actually causes probs..... but i wouldn't think a 180 would... it's not as big of a jump ours are 195* stock i think....

              The temperature drop on a 3.8 is only 20 degrees, and by getting a 180 on a 3.4, the difference would be 15. People with 3.8's don't seem to have problems, so I'm thinking that's the best bet.

                  I would go with the 180 man. I just flushed my cooling system this past weekend and went with a 180. I like it a lot! I keeps my engine right at the temperature I want. But with the 160 I think it would be a little cold. [img]graemlins/burnout.gif[/img]

                      i know you asked about the 3.4, but i put in a 160* on my 3.8 and its a 35* jump from the stock 195*, but i have no problems with mine. even the heater works better than most would have you believe.

                      a cooler engine is always better. the only time you might have a problem is during emissions testing. for that just let your engine sit idle for a few minutes until the fans kick in and then have them test it. should be fine.

                        Try the 180 ... or take a 195 and drill one or two 1/16" holes through the plate.
