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
