First Generation Firebird-L Mailing List ......................................................................... Remember, a thermostat is simply a closed valve in the cooling system designed to eliminate coolant flow until the core engine temperature reaches a desired level. Then it opens and allows coolant flow throughout the engine. Thus, a Tstat will do nothing to lower maximum engine operating temperatures, all it does is ensure the engine runs at a minimum temperature which is the Tstat temp. In fact, my view is that a Tstat on older cars is unnecesary unless you live in a cold climate.
To reduce maximum operating temperature, you need to look at multiple variables - radiator size, radiator efficiency, radiator flow rate, coolant heat transfer capacity, internal engine coolant restrictions, water pump flow/capacity, airflow restrictions in front and behind the radiator, fan speed, fan flow/efficiency, shroud design, etc Thanks, Mark Lueker 308 SYSTEMS Inc. 970-282-7006 www.308systems.com -----Original Message----- From: [email protected] [mailto:[email protected]]on Behalf Of Hugo Tafel Sent: Monday, August 24, 2009 10:52 AM To: First Generation Firebird-L Subject: Re: [FGF] cooling question First Generation Firebird-L Mailing List .........................................................................
