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.
