180 or 195 Thermostat (Page 3/3) MasterBaker AUG 12, 01:25 PM Originally posted my question over concerns of overheating. But what failed to ask is, does 1986 2.8L Fiero have overheating issues? I was under the impression they do. With living in the southeast was concerned. Is this something to be concerned over or am I over thinking this? jpeeler AUG 12, 03:46 PM quote Originally posted by MasterBaker: Originally posted my question over concerns of overheating.

I have had my Fiero in NC for over 15 years and my wife has had her's for over 10 and while mine is no longer a 2.8, neither of us ever had overheating problems on stock t-stat with a properly functioning cooling system. PhatMax AUG 12, 03:47 PM The 110deg was from a book….don’t remember which one….might have been Smokey Yunick. The air cleaners on older small blocks had the flap in the snorkel that was closed when cold…..opened when 110 was reached. Get things too hot and you get vapor lock. Trying to understand , I’m old school carb guy, when the weather is cooler out my car runs much better, when it’s hotter not quite as good. So if warmer temps were indeed better then why not preheat the fuel somehow ? Or build a shroud around exhaust manifolds and draw the air past it before it reaches the intake ? Help me out here..
