Help - OVERHEATING

[acessence]

Need some possible solutions or troubleshooting methods, we just rebult the head, replaced all the gaskets, etc, and now its over hearing again the friggin radiator is just boilding with coolant, like literally yah can hear it boiling. I have no idea, on what else can cause it to overheat. like just running it for 15 mins cause it to boil

Make sure your thermostat is not sticking. If your return hose to the radiator is not heating up while the supply hose is, then your thermostat is sticking closed. Tap on it a bit (not too much; aluminum housing) and it may pop loose.

do a compression test to make sure the headgasket is %100, if thats all good maybe a water pump.
