I have an 89 camaro rs its constanly overheats while driving it or sitting what can be the problem??
v6 to v8 upgrade also carborated.when i drive the express way the overheating can be tweaked if i dont give the engine gas(stick shift) on cruise is the only time it will drop to regular pressure.i've changed the radiator hose,radiator,theromostat,water pump, none of these are the reasons what could be the problem??
