Thread: overheating 4.6

hi wayneg
im getting more of a dribble out of the rad exp tank rather then a constant stream.would this indicate a worn water pump or air in the system?

the 8mm hose runs straight from the thor manifold to the bottom of the exp tank atm, the hose had been run this way before i brought rangie.

if the radiator was blocked wouldnt the temp guage rise at a constant rate? my temp gauage sits at half way for a while than at random goes into the red and the light comes on in 2 seconds so i turn rangie off but, if i start rangie back up after 1 minute the temp guage is back to normal.this is really doing my head in.

thanks for the help

regards brett

hi all

the coolant temp sender is in the intake manifold next to a 8mm hose that runs to the bottom of the exp tank.idont think that it is an electrical problem as when i turn the engine off i can hear the coolant boiling in the exp tank but i will have a look at the engine earth.

thanx brett
