the other day i put the air intake manifold back on my car and i had to unhok some coolant hoses and after i got everything back togeather it started to over heat slowly but when i revved it , it cooled down. and when i turned the car off the coolant reservoier boiled over... but yesterday i started it up after i quickly squeezed the large hoses ..and it didnt over heat , it only went near half ..i dont know if it was because there was air in the system or not, the fan clutch or thermostat. but im worried it'll do it again. (it isnt the water pump because it pumps water into the reservoier) another thing.. i have a liquid cooled throttle body and i wasnt sure were the hoses went (one hose comes from place near thermostat and the other comes out somewhere near the fire wall. )i dont know wich one goes on top or bottom? any ideas?
