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.

Not true. The filter tee should be in line before the shut off valve and flow anytime the engine is running. Mine does. Maybe you should recheck yours.

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

That's a negative. Start your engine, turn a/c to max or heater off and check the return flow to your degas bottle. It should be flowing. Mine does.

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.

You made this statement as tho this is the way yours works not that you assumed it worked this way. Not attacking you, just quoting you.

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.

He's got it hooked in the wrong heater hose. Tee it in the other hose right below the vacuum valve.

No offense but, I've never heard of anyone teeing the coolant filter into the wrong hose. This has to be a 1st.

Take a look at these installation instructions, they might help.

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?

The heater is supplied directly from the water pump, and is a bypass around the thermostat. So it flows whether the engine block is up to temp or not. In that same outlet line is the heater control valve. Your tee for the bypass filter is between the water pump and the heater control valve. The water pump will be pushing coolant at all times, even if the supply to the heater core is closed off. The tee is NOT in the heater return line. It is in the heater supply line.

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.
