coolant filter design flaw?
If the air conditioning vacuum valve causes the air to be colder by stopping coolant flow to the heater core when set on "off" or "max a/c", then that stops the flow into my coolant filter when on "max a/c"? If that's true, you have to run it on a/c and not max a/c. That's not so great in the middle of summer, or when the fan is off.

Maybe I'm understanding it wrong. I thought the filter was receiving coolant from the heater core outlet.

That's good to know. I'm at work and was reading the ranger valve thread and thought it might affect coolant filter flow. I haven't actually looked under the hood to see if the flow would stop.

There's an "If" at the beginning of the sentence and a question mark at the end of the sentence. I know you're not attacking me, you just read it wrong.

Actually running the A/C on Max will force more coolant through the filter because everything destine for the heater core would now go to the filter. So stay cool and filter your coolant.

Keep in mind that the Ranger valve pictures are of a 7.3. You won't find that setup on a 6.0, and the difference in plumbing makes it nearly impossible to splice your coolant filter into the wrong hose. Well, not impossible, but not very likely.
You don't want to use a Ranger valve on a 6.0.

How is the coolant going to go through the coolant filter if its tee'd in up stream of the valve or in the return hose of the heater core and the valve is almost always closed because you live somewhere hot?

Capiche?
But as long as we're discussing design flaws - my complaint with the coolant filter is the limited flow through the filter itself. The Baldwin that comes with the dieselsite kit only has a 5/32" diameter outlet. That's pretty danged small and I would like to flow more. But, the question is, will the cabin heater still work efficiently if more flow were diverted to the filter? I dunno.
