So I have a major question and looking to get an answer to. I have worked on my brother's 96 4.6 cobra by taking care of over heating issue. Have changed radiator from stock to mishimoto radiator, water pump, thermostat(180F) and temp sensors. Still over heating. Secondly heater core stopped working so we think it may be clogged and not busted since there's no leaks inside vehicle. But overall even after doing a bypass to see if engine would still over heat with out heater core it sure did. Only thing I can think of is a head problem or internal problem where water flow is not properly circulating. Water goes back or comes back to reservoir and shoots it out. Last of few test to do is running water through heater core and hope it comes out and also doing a leak compression test and see if we get an answer if it is a blown head gasket.
Thanks in advance if someone can help with an answer.
