Re: blazer runs to cool

^^ That's why it depends on how the heater hoses are hooked up. If the heater hose is hooked to the radiator it will by pass the t-stat and might not warm up if your running a bigger rad and electric fans. The heater hose should run to radiator if it is an auto. This was done to warm up the transmission on cold days, as to cold of trans temp can also be bad.

Put a 195 t-stat in if you needing more heat why even miss around with the cooler t-stats. Chevy motors run a little better with a little more heat anyway. Did you try switching heater hoses around?
