I got a 2002 7.3L PSD and I have a leak that i cant find.. its a clear liquid and could be fuel i cant tell ... its on the passenger side at the back of the motor.. now i have degreased and cleaned the valley and no leak was found the next day. now I have only notice the leak for the past 4 days and it has been very cold (it has been -7 to -18 below the past couple days) can anybody help me please thanks Mike
 
you need to figure out what the fliud is. If you taste it(not swallow) and it's sweet, It's antifreeze. I just did a water pump on my mothers 7.3 PSD last month. Fuel should have a strong enough smell to it that you'd know it's fuel. Also are you low on anything ? coolant etc ? Oil would be fairly obviuos in color as well. Sure it's not ice melting trapped somewhere on the motor ? How much are you seeing ?
