i just swapped a redtop s13 sr20det in my 95 240sx, and when i drive it my temp gauge goes up to hot and the engine doesnt get that hot for awhile, but it says its hot. the radiator hose doesnt build pressure for a while so i know the engine isnt hot but the temp gauge goes past the hot line, its goes to the H. also i have a stock ka radiator and fan. it doesnt turn on when it gets hot, i dont know y it doesnt turn on. i could turn it on manually but not by itself. does any one y it doesnt turn on. i check the relay they all work, i think it might be the ecu. does any1 know the pinout (redtop s13 sr20det) for the radiator fan. im going to buy koyo radiator a flex-a-flite fans, but thats not intill i save some money. i need the fan to work for temporary. please help

THE SR DOESN'T HAVE AN ELEC FAN. WHAT ARE YOU TALKING ABOUT IN YOUR POST? Did you check for air in the system?

*Edit*

atleast the s13's don't have an elec fan stock but i could be wrong about the s14 having them
