another radiator question

[bigguy69]

had a little problem with truck wantin to run a little hot. 3 core radiator. just finished running prestone cleaner through it. seem to help quite a bit. it has 1 16 inch fan on it electric. sittin in traffic it will keep creepin up. so far i have let it get 210 and shut it off. i know i need a shroud, but do you think the 1 fan is enough?i also went and bought another bottom hose as the old one didnt look to healthy. i asked the guy behind the parts counter if they had one with the spring in it. he said they dont do that anymore and the only reason the factory done it then was to pull vacuum on the cooling system.i have worked on cars and trucks since i was old enough to hold a tool. first time i had heard that one. so what you guys runnin? thanks in advance
