Just Installed

[TOPFUELF250]

Well, I finally installed my PMM coolant filter. Very easy install but one of the fittings wanted to keep leaking. I think I finally got it tight enough to stop it. We'll see. To all of you that installed the PMM filter, you might want to take a look at how close your heater hose is to the down pipe. I ended up cutting about 2" off of the heater hose just to move it away from the down pipe. I can imagine the heat coming off of that thing might take a toll on the heater hose. Just a heads up.

I had problems with mine leaking from where the ball valve connected to the filter head. I ended up buying some liquid teflon and tightened the heck out of it. Seemed to work no leaks since.

I just used the supplied teflon tape, put it on, crank it down, unscrew, retape, put it back on as tight as you can while lining everything up, DO NOT BACK IT OUT. and repeat for the other side. Never leaked

In regards to the downpipe, there are some variations in the hose and it may need to be trimmed. We recommend if you have the heater control valve to remove it from the vehicle completely and move the vacuum line to the closed nipple on the heater box. This really seems to be the easiest install on those trucks because the length of the heater valve crimps the hose up.

As far as threads go, put a generous amount of teflon tape on the threads, wrapped in the opposite direction as the threads. Doing it the same direction as the threads essentially unwraps it as you thread it in and will ALWAYS cause a leak.

I ended up trimming off 2" of heater hose and that seemed to do the trick. I did put about 3 layers of teflon tape on the threads in the correct direction and it still wants to leak a little bit. I'm going to try the liquid teflon sealer when I get back home after the weekend.

zip-ties keep the coolant filter hose away from hot and moving parts.
