Re: [Chevelle-List] thermostat recommendations?

[Mike Holleman]

Dan, Both guys responding are right. The 350 needs a 180 thermostat. If you have not changed your coolant lately, try a 70/30 mix, distilled water/antifreeze. This will protect you down to around 10 below and will cool better than a higher antifreeze mix ratio. Also, be sure you rad. cap is a high enough pressure cap for your system. I tried a 7 lb cap on my 283 Malibu and it would bypass and dump about a half gallon of coolant when the engine got up to temp. A 13 lb cap cured the problem and kept the coolant in the rad. to bring my operating temp back below 190. Hope this helps.

On the way to a show the other day, my car got up to about 220°F. I think the current thermostat is a 210°F unit... This was in stop and go traffic on a high 80's, low 90's type of day... I am running the stock 5 blade fan, and a full shroud. It is a 1971 El Camino 350 engine.. in a 1964 Impala Is this a common operating temp for this motor? What do you all commonly do to reduce the temp... I used water wetter in my Mustang, and it seemed to work OK, but it could have been the placebo effect...   Thanks people!     Dan McIntosh Pavement Scraping 1964 Impala SS http://www.alloldchevy.com
