engine still not cool enough

1st radiator capacity ??? stock 2 row ?? 3 row ??

timing set properly???? plugs white ?? tan ?? black ??? if they are white you are lean,,and it will run hotter,,,

a good factory 3 row radiator should be good enough,if all other things are correct,

i had a be cool,,,went back to a factory style with 4 row,,160 high flow t stat,,, manual flex fan,,,NO ADDITIVES,,,, runs 178 in the dead of summer on the interstate,,,182 around town,,, blown 340,,electric fan, only needed in traffic when out side temps are over 95
