Direct Injection Performance

Coolant Filter

  Not only is the Direct Injection Performance Coolant filter a well built complete kit, it is sent 75% assembled.  As you can see in picture #1, all the pipe fittings are put together with teflon tape, and ready for you to install in your truck.  The only part left to you is cutting the supplied hose to the correct lengths for your install.  The kit also come complete with ball valves to make filter changes easier, an with less coolant loss.

It is very important that this kit be installed on a cold truck, with the de-gas cap removed.  The filter mounting bracket is held in by a bolt and the rubber grommet on the radiator.  As you can see in picture #2, you have to remove the tab holding the positive battery cable in order to get at the 10mm nut.  Once that nut is loose, you can get your filter bracket ready to slide in.  You will want to have the bolt and spacer in place before you slide this into place (picture #4).  The grove of the bracket will easily side into place between the rubber grommet, and you simply lift the plastic radiator covering to insert the large washer, and screw on the 9/16 nut (picture #5).  Tighten both the rubber grommet and the bolt at this time.

Picture #6 illustrates the intended position of the filter head.  This position allows for very easy access to the filter and valves.  We also found, that with the purchase of a 3/8 90 degree fitting we were able to lower the filter bracket and still have good access to the filter, with a more show like finish. Since this truck will attend car shows, we opted for the more low profile look.  The installation will be the same in either position.

Bolt the filter on with the 9/16 bolts provided in the kit and close the ball valves making sure the arrows on the filter head are flowing in the proper direction.  The coolant will be flowing from the passenger side to the drivers side..  Connect the 3/8 hose to the filter output and tighten the hose clamp.  run the hose over the fan shroud, and cut the hose so the 3/8 brass T will sit nicely with the radiator return line. (picture #9)  We found it very easy to cut all the hoses in this kit with a set of multi-purpose cutters purchased from Sears.  Insert the T, mark the cuts on the return radiator hose and cut that.  You will get a few drops of anti-freeze out of this hose.  Make sure to leave room for the barbs to insert in the hose and not contact any other fittings already in place.  Picture #10 illustrates what the fitting should look like once it is installed.

Remove the hot side CAC tube at the top and swing it over the alternator.  This gives you a clear view of the heater core line.  (Picture #11 & #12)  Hold the supplied 3/4 T in place and mark your cuts with a felt tip pen.  There are some bends in this hose, but we found we could place the T between 2 of them and get a perfect fit.  Once marked, we connected the 3/8 hose to the inlet on the filter head, routed the hose to the new T and cut it to length,  and attached it.  Once it was attached, and we checked our ball valves again to make sure they were closed, we cut the 3/4 line.  If you move fairly fast you can remove the section of hose fairly quick, and insert the T. (Picture #13 & #14)   Don't forget to put in your hose clamps, or you get to pull it apart again.  Tighten the clamps, and replace the CAC tube.

We also did another variation on the T since we needed a place for our water temp sender for our autometer gauge install.  We drilled and tapped the back of the T with a 1/8 inch NPT and screwed our sender in before we installed the T.

Once the CAC tube is back in place, and your hose clamps are checked to be tight, you can install the filter and open the ball valves.  Through this install you will most likely lose 2 gallons of anti-freeze, so replace it making sure not to over fill it.  Also, be sure to use the G-05 anti-freeze, and not the stuff that says it will mix with all other types.  Zerex was the easiest to find for me at 14 dollars a gallon.  This system will de-gas itself very easily, and filling over the max mark before starting is not needed.  Warm the vehicle with the heater on to make sure all the gas is out.  Once it is warm, carefully feel the filter and return line to make sure you have flow.

Pictures 15-18 illustrate the difference in placement that is available with this kit.

The install will take 1.5 to 2 hours to complete, including cleanup and running of the truck.  Since it is assembled together, it is a simple bolt on application, and the hardest part, if there is one, is cutting the 3/4 hose.
