160* thermostat
OK...found out that the truck I bought did not come with a thermostat so I went to NAPA and was given a 160* thermostat. Is this the right spec for my '67? It has a '78 350 motor and no heater/ac system (has been deleted). I hear 180* is good, but can a 160* be used and still have good efficiency with my truck?
Also, what the heck is the difference aside price and degrees? Premium, regular, economy...LOL, what is good for my truck, ahah!! http://napaonline.com/Catalog/Result...0014%2b2014024

Re: 160* thermostat
I prefer a 185* thermostat, used 'em for decades. Our engines were designed to run around 200* IIRC.
That said, you can use that one but you may not reach full operating temp. That's okay just not preferred.

Re: 160* thermostat
I too have a 160* in my 402 BB. I was told the cooler the better. Engines burn fuel more efficiently the cooler they operate. I thought part of the reason was the physics of gasoline's volumn changing as temperature changed. Similar to the volumn of gas dispensed at the gas station with temperature change.
Have I too been misinformed? When I got my truck, I put in a 195 thermostat, but since changed to 160. Should I go back to 185?

Re: 160* thermostat
The biggest advantage to a 195 thermostat is your heater will work better in the winter.

Re: 160* thermostat
the cooler a motor runs the more gas it will use, and the less power it will produce..the intake needs to be hot to vaporize the fuel going to the pistons, a 180 would be better than a 160....but a 190 or 195 would be better than that...colder air going into the intake is good but once it goes into the intake it need to vaporize for a better burn. more power, more mileage..you may also need to change the rad. cap to like a 17 lb. cap...and add an over flow tank...i have always done this with good results....

Re: 160* thermostat
i have always read that at 180-190 the enging clearances are at spec and with a no thermo or lothermo your runnig things with closer non optimum tolarances
i have mostly used in the 190 range for my old vehicles// and when i lived up north i liked having a hot heater

Re: 160* thermostat
When I lived in Las Vegas I had a 69 C10 with a 454 in it. The only way I could keep it cool was to run a 205 thermostat. It worked for me there and since I've moved back to Iowa I still run 205 stats,, heater will run you out in the winter. I'd rather have to open a window or turn the heat down than not have heat.
I have never run anything less than a 190 stat in chevy v8's. |

Re: 160* thermostat
Here is really good article about how the cooling system works... with a good blurb on the concept of thermostats.

Re: 160* thermostat
When I was talking to my engine builder He recommended I stay with the 160 I was already running. weather it's a 160,180,195 I like the robert shaw high flow stats myself. they are less restrictive and I run a high flow water pump.
There are a few benefits to living in southern CA.. Whats this winter everyone keeps talking about ![]() On another note the new yukon temp runs at 210 and thats normal (better emissions, fuel efficiency, etc. I assume) I cringe when I see it though.

Re: 160* thermostat
My '06 Silverado K2500 6.0L runs right below the 210 mark on the Temp gauge. Once it heats up to that temp... it never moves. Whether I'm driving around town or haulin' my travel trailer... it has never heated up over that mark. I'm sure the stock T-stat is either a 195 or a 200...
I've always used the 180's in my first gen SBC's. I've never experienced any over heating issues in all the years I've been using them. Gary

Re: 160* thermostat
I use a 160 stat in the AC trucks and a 180 in the non AC Burb.
