[69terra69]

hi guys i have a 92 lib gx and it seems to over heat really quick.
if its stone cold and i start it and let it idle within 5mins the coolant starts overflowing from the reserve tank and its pretty hot has anyone know whats goin wrong?

i have flushed the system brought a new thermostate and radiator cap i just have no clue whats wrong i think the radiator cap is opening b4 the thermostate ? i dont know so has anyone had the same problem ?

cheers james
