Installed new radiator, Temp still kind of hot.
Hello guys, I am having a sort of problem that I can't figure out. Fist off this is sitting in an 86 s 10 I have a 350 chevy with iron heads and block. I am using a regular fan not electric. No schroud,fan sits only about three inches from the radiator. The intake is aluminum. I did have a four core brass radiator that came out of full size chevy truck early 80's. I have a 160 thermostat and a high volume water pump.
Last summer it ran around 160 to 170 all the time never got to 200 on the highway. It would see 200 rarely if I sat there and idled and was in stop and go traffic and did not get moving but once I got going it did ok temp wise and was steady at 170 to 180. Ok I just installed a griffin universal radiator with similar dimensions as my brass radiator. Its a two core with 1 inch rows and the size is 32 inches wide and 16.5 inches high core height. The old brass one was only 1 inch taller core height wise but the same length. Ok I just finally got everthing back together after changing out my gear drive for a new timing chain and finally got it up and running.
Ok there are no leaks and I checked everything. Ran it till I needed to totally fill up the radiator after the stat opened up. The temperature was running the same as it did recently with my old radiator. It went up to 160 then the stat opened up and the temperature went down to about 150 then got up to 180 and stayed there and then want to kind of creep up to 190 and almost 200. It goes kind of back and forth and I get nervous with it doing that. I have no air bubble that I know of. But I don't want it too run 200. It always ran at 180 and stayed steady last summer.
Thermostat is a high flow non restrictive for high volume water pump. I don't have a shroud on it yet. I am going to have my dad custome make one from some sheet metal. Any advice.
