He guys have a quick question. i have an 02 qx4 (pathfinder clone) i had to replace a hose on my water pipe. i get everything done, bleed the system but something peculiar is happening. the car is not running hot, i have my scanner and im getting temps of 187 to 194 on it. i drove several miles no over heating but the lower radiator hose is cold. my first thought was the thermostat went out but it was not giving my any trouble and on top of that im getting great heat inside. any ideas what could be causing the cold lower hose? im stumped
