Coolant flush and coolant filter install

[beemerbiker5]

I am planning on doing the coolant flush in the fairly near future. I would like to add a coolant filter, too. My question is, would it be helpful (or wise) to install the filter before doing the flush? I was thinking that running the filter for a few weeks, keep changing it as necessary, would help with the flush when I get around to it. Or would that just be a waste of several filters?

On a related note, I am thinking of changing the oil cooler at the same time. Should I flush before changing the cooler? It would seem to be a waste of time to flush after changing it, all the crud would just re-settle in there, right?

TIA

Flush before adding the filter and before replacing oil cooler.

Yup. Do your flush first, then change the cooler add the filter and fill'er up with coolant.

Do you need an oil cooler? I did my flush yesterday and then did my filter.

All the flushes took about 5 hours (even with pulling the stat). The coolant filter took about 15 minutes.

Not sure. According to my Scangauge, the cooler seems to be ok, now. I am going to do the coolant flush/filter first and see how things go. I hope the cooler is ok after the flushing, keeping fingers crossed!

What are your temps now, before flushing?

At a steady 65, ambient of around 50F, empty truck, the ECT shows 181-182, think I need to change the tstat, and the EOT is around 190.

That's the same delta I have. Only difference is, my temps are running 10°higher than yours. My ECT is running 190-192 and EOT is 200-202.

I figured since I'm going to do the coolant flush, and the tstat should be removed to do this, just as soon put in a new one, peace of mind sort of thing. Based on the great how-to by PGreen.

Just curious, why would flushing after adding coolant filter not be a good idea?
