I've seen this on other trucks, but I decided to do it on mine.

Snip the pressure expansion tank line and put a small universal filter on it. I doubt that it filters a whole lot, but it is a clever way to inspect the coolant.

Since the IDI has an overflow tank and not a reservoir, I'd reckon about 1% of the coolant ever flows through that. And good thing, too. If any significant percentage of the coolant flowed through a filter that size, it'd be done for in probably a month.

I installed a water filter just like that on my boat (Chevy) just used smaller fittings to reduce flow to filter 3/8 line works great, I use filters with out sca's in them for the boat. if you plan on installing turbo, all turbo's have a oil flow reducer orifice in the oil line as would an oil bypass filter, most turbo installation's drop the oil back where cdr was.

I just unscrewed it with an 1/4 hex socket and threaded in a 1/4" NPT barbed fitting.

I know the filter has a flow control orifice but I ordered one from McMasterCarr anyway, that way the flow is restricted right at the block.

Here's the final version of the oil junction.
