Well, as we all know, getting the sediment and rust and dirt and everything else out of these motors is a bit of a task. Pulling knock sensors, reservoirs, and everything else just to clean the system out are some of the procedures I have read and tried. But it never truly gets ALL of it out. Unless you take the engine out and hot tank all the parts of course. So with all the space we have in these giant barges, why don't we just fix the actual problem right here, right now.
So here I present you, a walk through of installing a coolant filter in your GM B body!
First thing you have to get, is a coolant filter base (Baldwin CFB5000), coolant filter (Napa 4070), some 10mm hardware, and some 3/8 inch hose and hose clamps to match. Once all those are obtained, you can start the first step; pull the top radiator brace (10mm bolts)
Then you will need to layout where you want your holes. I put mine as far to the passenger side of the vehicle as I could for the sake strength and closeness to the reservoir. Then drill holes and be careful of clearances! Measure 3 times here!
My bolt heads would not clear the webs on the bottom, so I notched them just a little bit!
From here its easy sailing. Have a washer for the head side and I put a washer between the filter mount and radiator brace. Looking back I'll probably take those out. The filter mount surface is machined along that surface and will yield more area of contact actually.
I used flanged nuts and cut the bolts to the length I wanted. Worked perfectly!
Once the filter mount is tightened down to the brace, you can put the brace back in the vehicle and reinstall the 4 10mm head screws. Tighten them down accordingly.
Now simply plumb your coolant lines from your steam pipe into and out of the filter head like so.
A 90 would have been good for the outlet, but I bought all the bits and pieces beforehand not knowing where I would place this filter. Get a 90 if you are putting your filter in this general area.
Tighten the clamps down, start it up. Check coolant level after a couple minutes and add if necessary and drive till she is clean!
Filters are relatively cheap, so replace them one or two times a year!
