Hey guys i got my swap done about a week ago (s13 blacktop in a s14) and i work out in tampa. I've noticed over the last couple days that the temp guage is all over the place. a few people say that its normal but if I'm driving at a constant pace than it stays right at normal running temp. If I get in any kinda traffic it goes nuts! At first the thermostat was stuck shut so i took it out until i can get a new one. And I have a koyo radiator and a crazy fan that i run off ignition power so i know its running. So if anyone has any tips or suggestions it would be greatly appreciated!! Thanx!!
