thats a lot of nice info to have thanks a lot! not to get off subject but whats this 4.5 Diesel engine? never heard of it,was it not offered in the United States

that sucker wouold be saweet stuffed into a ford ranger thanks for the info to bad it wasnt in production long
ya then id have to have the ranger also lol..just an idea to dream about along with my heated garage and all tools needed wow im bored where is spring at getting cabin fever already
ya thanks..id be out n the desert riding if i was down there!!!!!!Swing by here! 70 degrees yesterday

IIRC they originally designed the engine with the intent to offer it in the F-150...but, the problems with the 6.0l soured the relationship to the point where Ford abandoned the idea. Shame the LCF got killed off...other than being lacking in legroom (the floor wasn't low enough compared to the Isuzu NPR, and you can't go forward on a cabover), they were good little trucks. I rented one from Budget a few times...that sucker wouold be saweet stuffed into a ford ranger thanks for the info to bad it wasnt in production long
maby they will or have reopened it since dodge has thier little diesel coming out this yearIIRC they originally designed the engine with the intent to offer it in the F-150...but, the problems with the 6.0l soured the relationship to the point where Ford abandoned the idea.

The orifice in the coolant line to the heater core is to reduce the fluid pressure not the velocity. For incompressible flows (liquid is negligibly compressible), a reduction in the flow area results in a increase in the flow velocity. Mass flow is constant therefore the flow velocity must increase when going through a smaller hole. Bernoulli figured out that as flow velocity increases, the pressure decreases.

What is used in the head is basically a restriction orifice. It reduces the downstream pressure of the fluid past the orifice so as to not pop the heater core.

Disagree.
Pressure in the system is going to be fairly constant - the entire system is pressurized. Restricting one side of the heater flow path doesn't keep backpressure from getting to it. There is some pressure differential due to the pump, but probably not enough to where not restricting the flow would cause a heater core failure.
I expect the restriction is more due to the fact that flow through the heater core essentially short circuits the engine cooling, so you don't want any more than you really need going through there.
I seem to recall reading somewhere that that thing is actually a thermostat intended to help retain heat when the engine is cold and aid warm up.
Here's another interesting document:

This time I was searching for how to determine the build date of my engine via casting marks, and found this. I should just keep thinking up unique ways to search for stuff related to my truck!
Covers 6.9 IDI, 7.3 IDI Non Turbo and 7.3 Powerstroke. Also 6.0 Diesel
