works fine and my water pump is fine ,? My bottom hose is really cold even though the top hose is really hot . . and help would be really cool.
i check thermostat its in right. i changed it cause it was reading hot . but still nothing changed
Plus i cahanged temp sending unit
Well the top hose that comes out of the thermostat is hot but the bottom is cold . i took the rad cap off and squeezed the bottom hose and fluid came out of cap area so its seems to me its getting flow .. the fan works great also.the sending unit is on the therostat housing also . i changed that
i thought the radiator going out was a rare thing
