I have an SR that heats up at idle and keeps climbing but when i i get moving it starts cooling down. i dont think its a warped head or headgasket issue because itcools itself back down and the coolant doesnt geyser out of the rad cap when i open it

has an aluminum rad and a FMIC

I read it might be a clogged cooling system, air in the system, a half stuck thermostat or my cooling fans.

im gonna get a coolant flush. i tried to bleed the air today but i might not have done it right (removed the bleeder screw by the exhaust side of engine)

anyone got any input on this?
