Hi guys, here's the deal. Gotta a 1j in a 240sx. But as of late, its been overheating. I just bought a brand new Koyo radiator and have 1.3 bar radiator cap. I doubt the radiator has an issue because its brand new. The cap, I'm going to get a lower rating cap, but haven't done that yet. Other than that, what could be the issue? What is the proper way to bleed or burp the system? This is how it over heats. If I'm just cruising either city or hwy, the temp remains at about 185-190. As soon as I mash on it, temp rises rather quickly to about 220 or so. Then it just hangs there and will start to come down very very slowly after a long time of driving. My theory is, if the fans weren't flowing enough it would overheat in the city, but be fine on the hwy. What you guys think could be the issue? oh, and its a new t-stat. Thanks for you help.
