Small leak spraying out of a steel pipe onto the front of the motor. This isn't my truck so I'm not very familiar with it but looks like there is a pipe that come from the water pump threw a bracket and y's and one end has a hose going to heater core n the other part is where the leak is I think it has a hose connected to it that goes to the intake. Only leaks when thermostat open.
I'm going to take it apart tonight n see what I find. Iv looked for a replacement part and found nothing so I am going to try n replace the steel pipe with hose.
I know on my 98...but a 4.6.... that tube is less than $20.00 bucks at Rock auto. Also scroll to "Cooling"...the first item is water outlet O-ring...that may be the item in question in that thread that Torky 2 is linking...not sure though.
I got the part off advance auto can get the part for 125 but I am just gunna weld it up at work. Def a stupid design plus should be made of better material. I got an oring outta a kit no parts stores had it. Also rock auto only sells the motor craft part now and had two different ones listed w no pictures so I didn't know what to get.
