170 Deg.....Too Cold or Okay

[1Slow90coupe]

I put a 160 deg thermostat in my car just to see what it would do. Now the temp stay at 170-175. is this okay or is it too cold?

It's a little cool but should be fine. Come winter time, see how it does (or is it winter elsewhere? It's 90* here today).

Thats sounds just fine. Warm enough for it to run properly, cool enough to ckeep the under hood air cold. As long as it runs good, your good to go.

Thanks for the info. I am going to try it for a little while and see how it works out. It was 93 here today.

My opinion here is a little different than others.

I feel anything under 190F from the ECT is too cold.

Below 180-160F engine wear increases rapidly.

Power can actually decrease with lower temps

Economy can decrease with lower temps

I have never seen dyno tests on coolant temps, but if anyone has them I would love to see some proof either way.

I like to run at least 180* my truck had a stuck open fail safe t-stat and it got 8MPG I changed the t-stat to a 180 and now it gets anywhere from 14-17 mpg at worst

same thing happened to me after i installed a new water pump.. mine wont get warmer than about 160 or so.. even on long trips. worried me at first but runs great

i agree with vristang.too cool

I realy don't care about the MPG. I rarely get to drive my car, However the wear does concern me. It is just a see what it would do effort until I get a new radiator. I just can't seen to make up my mind on which one to get. See other thread on Alum vs 3 core copper brass if you can provide info

2 or 3 core copper from your local parts store.

I'm running a 2 core in my 408w.

I just realized that your using Nitrous. That is a little different than n/a. You will want more cooling capacity.

Remember that you can loose power by running too cool.

i also think you could have problems with carbon buildup running lower temps especially in colder weather...
