i need to get a new radiator soon, i was thinking of upgrading to an aluminum one. any thoughts on this, or should i just go with a stock radiator. i have a 1985 pickup 22re 5spd. would an aluminum radiator cool my engine that much i was also thinking of getting an electric fan from flex a lite. input on the fan would be appreciated. also what companys sell an aluminum radiator for a 22re.
