So started having an overheating issue, replaced the thermostat first, still overheated, next replaced the radiator, still overheats. I've tried bleeding the air more than a few times and a few different ways with no luck. When it starts overheating the fluid will push up and flow out from the reservoir and through the cap. No white stuff in oil, no smoke, no leaks that I can see, other than overheating no other symptoms. Any suggestions?

 

block test or use a funnel and look for bubbles when the engine gets to 210 or above if you see bubbles you have warped heads.
