195 to 180 thermostat
My first visit and post to this site and I can't tell you how great it is!
I want to go from a 195 to a 180 degree thermostat on my '92 Bonneville SE (only 54,000 miles) as summers here in NJ can be a real bitch - especially when stuck in traffic on the Parkway going down the shore on weekends.
I recall a GM mechanic recently telling me that switching to a cooler thermostat might negatively effect the computerized components, upset the emissions, fuel economy, cause possible carbon build up on certain parts, and distract from the normal operating temperature the engine was specifically designed to operate at. Has anyone else heard these type of answers before and would switching do any real harm to my car or would it actually be more beneficial to go to a cooler operating thermostat?
