I have a 1968 Firebird 350 - 2 speed convertible. The car continually gets hotter as you drive. Pulled a small grade today and it hit 235 degrees!!!
Here is what I have done to keep this thing cool:
$700 Super Radiator, dual electric fans @ 180 degrees (eBay) Closed divider plate gap Oil Cooler w/ remote filter (removed because it didn't help) 180 degree Thermostat replaced (right side up) 19" 7 blade fan w/ clutch (now removed) Coolant Wetter 50/50 mix Engine is Rebuilt w/50 miles since rebuild Tried 8 bolt water pump and timing cover (now removed) Tried a 4 core radiator with shroud spaced 50/50 (now removed) Timing is set 12 degrees BTDC All filler panels, baffles, and inserts are there Headers removed Tried 3 different water pumps
I am at my wits end. The car has ALWAYS run hot and everything I have done hasn't cooled the car by ONE single degree. The car has a 2 brl carb (Rochester), therefor I am not racing it and driving it pretty easy.
I just ordered a Meziere electric water pump. It is supposed to pump 35 - 40 GPM. Has anyone ever tried one of these water pumps? Did it help cool the car?
