hey guys just was getting ready to peice together a coolant filter kit. I was just wondering about tying the filter bypass back in at the heater return line vs tying back in at the smallest line to the coolant degass bottle. Now I am going to put the valves at the filter both sides for less coolant loss during a filter change and possibly to regulate the flow. Is there a reason for the kits that I have seen that tye back in at that small line. I just thought that it might filter more coolant if I didnt reduce down so much. I dont know what am i missing here??? I dont care would like to hear the good, bad, ugly. Thanks for your thoughts.

 

the bigger the hose will not help out any?that is only a return line from the heater core it's not a high presser line.it's still only going to filter the same amount of coolant

 

I did my own DIY redneck coolant filter just to SEE what I was collecting in process. I can't take credit for the idea (don't remember the OP's screen name so speak up) but I did change the location for it.

The OP installed a "fuel filter" inline between the radiator and degas bottle. I originally installed a "glass fuel filter" there but was unhappy with the volume and quality of the flow. It was really a part time thing, so I moved it into the EGR cooler deaeration port line between the Intake manifold and the degas bottle since it's a full time flow. 20 miles and I was amazed what I collected but so far no reduction in coolant flow. I was also amazed at the constant parade of very small bubbles from the EGR cooler deaeration port.

 

Very interesting! I have also noticed the very small flow of water into the Degas bottle. Will be interested in your conclusions.

 

The flow into the degas bottle from the DieselSite Coolant filter is normal. When the flow stops, that means the filter is clogged and needs changed.

 

What you are missing is the restriction within the filter itself. The discharge hole out of those Baldwin filters is 5/32". Much smaller than any hoses you would use. The filter itself is the limit to the possible flow.

You can tie it back in at the heater return hose if you want. But there are a couple of drawbacks. First, have you seen where that hose is located? It goes behind the engine, along the firewall, and into a Y below the degas bottle. Second, you won't be able to see the return flow, so you won't have that to determine when to change your filters. All in all, it seems like it complicates things without any benefit.

 

I don't have a coolant filter. I experimented by adding an inline filter in the two small degas bottle lines. The one from the radiator had, at times, little to no flow. The one from the EGR cooler has flow constantly, which is what I wanted. Open the hood, easy to visually check and easy to service, plus getting MORE flow than the filter kits. I just wanted to see if I needed to flush before my Bulletproof oil cooler install.

 

I put mine in a while ago and have gone through three filters....the first two were changed at short intervals as recommended. I tore the filter apart after dryingit out but nothing was really in my system.....I got lucky I guess.

 

Ya I got looking at the filter base today and saw the same thing you mention about the discharge hole only being 5/32. The inlet was 3/8 so I think that I can run a drill bit down the discharge side of the filter base and ream it out to 3/8. And im glad you guys mentioned a sight glass i didnt even think of that. I will try to find a sight glass when i get the valves I dont know if the hardware store carries those. All i do know is that it will only filter what ever the smallest fitting will let by. Jus think about all the modifcations people go threw to put a fuel system on these trucks to get more flow change to bigger fittings and lines ect..I think if I ream the filter base out and keep the lines as big as possible tye back in at the heater return it should flow about double as the kit thats out there. I also got a peice of aluminum fish plate to make the braket out of . isnt there two diffrent mounts everyone uses. any drawbacks for either mount.

 

I got the filter base mounted today with the braket made of diamond plate. I was going to tye in at the heater supply line befor the valve.Somehow I was going to see if i could get a gallons per minute going here I will post the results of before and after i drill the discharge hole of the filter base. to see if i get an increased flow And then i was going to tye back i n at the heater return line.

 

exactly to the point, which makes the small diameter hose more than enough for bypass filtration. But there's nothing wrong to bounce ideas around, that's how new stuff's created.
