I have a 91 camaro rs v8 5.0L, recently started to overheat and emitts white steam from the water pump, replaced water pump and thermostat, checked top and bottom hoses, checked radiator for buildup but nothing, still overheats. Also even while the steam is coming out the radiator is completely cool, the cap is good not loose or anything and apart from a few drops of coolent no major leaks. Is it mabey the radiator fan? Or something internal? Overheats slowly while in park or neuteral, overheats faster in drive. Runs good theres no engine knocking or anything when its idleing or when im reving it. Any help would be appreciated alot.
