Overheat problem on small port 4AGE
Posted: Mon Mar 14, 2022 10:03 pm
Looking for some help here...I have a JDM red top small port with over heating problem. At cold start the temperature would stay normal (60C / 150F) for approx 10min and then rapidly raise to 105-120C / 220-250F. I've install a new themostat, also tried remove it entirely, both with same result. Tried bleed the system by open the radiator cap and park car on a slope, I can see coolant spill out when rev engine to 2-3k rpm, is that normal? Seeking for advice to how to troubleshoot the issue. Thank you!
