160 or 180 thermostat on a 3.4

[CamaroKing]

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?

good info man..... i was wanting a 160* but, i didnt knw if could be bad for our cars.....

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

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]

Try a search. This has been discussed to death.

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.
