WARNING - Check your heater hoses.

I was doing a CCV Re-route on my truck and noticed that the heater hose that comes from the heater core to the top of the intake had moved off the fitting some.
If you stand on the bumper, and look down to the valve cover behind the oil fill and the tranny dipstick you will see it. I had about 3/4" between the end of the hose and the point it was supposed to be.
I got it pushed back on. Just squeeze the spring clamp and push it back on.

Now I hate spring clamps and this is the reason why.
The damn hose leaked after. I drove the truck to work the next day and when I got home I noticed that truck was a little wet on the front suspension. Lost only lost about 1" in the degas bottle.


So if you have a connection leaking that has a spring clamp, replace it with a screw type one. Take the spring clamp and beat the piss out of it with a sledge hammer. I will get a count of clamps on the truck, when i do maintenance for that part, I am going to replace them all. I learned this with my 96 Impala when I got the car, but did not know what I was thinking with this truck.

The problem with the connection that was coming loose, is that it is a plastic tube that runs to the front of the motor. That plastic tube is very easy to break, so if you torque down too hard with a hose clamp you can crack it.

It leaked with the spring clamp, not the screw clamp. Just didnt have enough tension anymore I guess to hold it. I didnt have to compress it too far to slide the hose forward or off the fitting.

AND if you crack that plastic tube you have to remove the intake manifold to change it........and that means the cab is coming off. so beware!

it's sandwiched between the right cylinder head and the intake manifold, there is no way to get it out of there. it reaches the front cover underneath the intake elbow

I know this is an old thread, but this pipe is currently cracked on my truck. the reason I know its cracked is because i had to take it off when I was installing head studs.......with the cab on. So guys, please realize u dont need to pull the cab for every repair. as a matter of fact you dont NEED to pull the cab for any repair on a 6.4 it does make it easier, but if you put your purse down and use both hands it can be done. Sinner6.0L being a "ford master tech" im suprised you dont know this.
