Ok recently i changed the headgasket the thermostat put in a brand new fanclutch and it was running fine until until the next day it started to overheat, its fine when its on idle but when it gets warmed up and i start running it the temperature starts going up, then i put it in neutral and let the rpm go back down to idle and it goes back down to normal slowly. do yall have any idea what this might be? People tell me it might be that because i used the same head bolts the mechanic that changed the head gasket didn't tighten them enough. Let me know what yall think about this. thanks
