Coolant Filter Installation -1987 PT38 – 8V92

Contributed by Curt Sprenger August 27.2008

Coolant Filter Base – WIX 24019

Filters – 1^st filter NAPA 4074 (WIX 24074). In a year, and each year, change filter to WIX 24701.

Parts – All Brass, all 3/8" - 4 street elbows, 1 close nipple, 1 1-1/2" nipple, 2 NIBCO T585 ball valves. Cost $68.79. You might find the part for less. I shop at a plumbing store that carries more parts than anyone in our area. They are not the least expensive but time is worth something.

Hose – measure generously – I used just under 6' - get good ½" push-on or equivalent. Cost $10.00.

Hose Clamps – 4 each.

Bolts/Nuts – to mount the filter base.

Instructions -

1 I removed the Ether Injector system and installed the coolant filter base in the same location. Or

pick a different location.

2 Loosely attach all the plumbing to the filter base, see picture, and the spin on the filter (not tight), to

get an accurate mounting position that works. Keep the coolant hose clearance/routing in mind.

3 Drill new mounting holes if needed.

4 Install filter base.

5 Install the brass parts. See photos. Shorten the ball valve handles as needed. Use thread

sealant.

6 Tighten the filter.

7 Remove the old hose at the Expansion Tank, save the coolant. Plug the hose for now.

8 Connect new hose from the expansion tank to the filter base center.

9 Connect new hose to the filter base outer connection. Run the hose to the thermostat housing

street elbow to get the length of hose needed, and cut to length.

10 With a knife, slit the old hose at the street elbow on top of the thermostat housing. Quickly

remove that hose and slid on the new hose. A terry towel on top of the thermostat housing will catch the small amount of coolant loss.

John thanks, I was thinking of one inch or what ever size makes the
loop to the potable waterheater. blockage there is of little issue
and no hot water at the sink would warn of a clogged filter. I like
the idea of the filter being in a path like the waterheater because
it is right off the pump and as the filter fills with crap, it
catches smaller and smaller particles. placed in a spot where the
path around is less restrictive will prove to become the path of
least resistance ans the filter become only moderatly full.

The other advantage of a coolant filter is you can get them
charged with additives (RobR a Canadian, but ok)

Greg,

From my research John ??? is right. All coolant filter bases that I checked out were 3/8". If you want to build one to work with larger flow (1" line), we can build you one...I like your thinking. The only caution is the filter additives...maybe too much additive getting into the coolant system in a shorter period with that 1" line. Without getting into too much here...my understanding is the filters are designed to support or do their job over a one year period. You use filters with more additive the first year, and the second and subsequent years use filters with less additive. That could vary depending on the annual coolant test results. Maybe do an semi-annual coolant test and change filters then if needed. The science is close to the same as taking care of a swimming pool.

Curt's right about worrying if you're getting too much additive in
the system. I slightly overdid it in my 7.3 and ended up having to
replace the water pump because of it. Definitely something to keep
in mind. I wouldn't worry about the restriction in the filter
pushing fluid around it, that's the whole safety factor of this type
of system. Adding the filter will help. If it plugs completely,
where are you? No worse than you are right now and a simple filter
change immediately puts you back better than where you are now.
Looks like a win/win to me. I need to do mine!!
