Coolant filter plumbing with engine coolant heater and cab heater

[joshs1ofakindxj]

Can someone verify my plumbing is correct? I did a lot of reading and studying pictures but I couldn't find anything matching mine exactly so I hope I got this right.

I have the engine coolant heater installed down low in the water pump by generator.

When I say rear or front, I mean in the directions of the rear or front of the truck.

Referencing the pictures, the forward, slightly lower connection on the motor goes to the forward connection of the cab heater core and connects to the outlet (top) of the napa filter base. The upper, rear connection on the motor goes to the rear connection on the cab heater core and connects to the inlet (side) connection of the napa filter base.

Well how did I do?

Hard to say, I would imagine the coolant would take the path of least resistance(meaning it would bypass the filter). Might want the lines to go to the filter then to the heater in one big loop.

I read that set-up will limit flow to the heater core, since the filter will not pass full flow volume, as it is a by-pass filter. I need my cab heat.

Looking at the filter, the orifice in the center for the return is less than 1/8" diameter.

Run it as it is!

I attached my filter unit to the side of my heater. In the winter I have the coolant hoses attached to my Heater and the filter plugged. The other three seasons of the year I have the heater plugged and the filter plumbed in. Not elegant but simple and three seasons is the year is better than none I figured. I cut open the filter at the last change and it was as nasty as all of those other pictures.

Not related to the above post, but for the record, that is the location my heater hoses went to before I put in the filter and new hoses, and I did have good heat in the cab. Smelly, but good heat.

I think Russ was just saying that he ran the hoses to the filter for most months and to the heater when its cold, not that your hoses are wrong.

 

[joshs1ofakindxj]

Yup, I got that. I was just throwing out that this isn't something I completely came up with last night for any fans following along at home.

I apologize if I came across as criticizing. I was just posting what I did. No offense meant.

I agree with gimpyrobb, your filter is simply taking up space the way it's hooked up in the picture. The only time any coolant would flow thru the filter is when the flow to your heater core is blocked off.

There's diagrams in several posts by cranetruck on this, but you'll need to go back and search them out. The addition of a filter in the deuce cooling system is a very good idea, but only if it works all the time as intended.

Your on the right track...

I might be a little slow, but can someone tell me why there is a need for a filter for the coolant? Thanks.

As far as I understand it, the block is iron and slowly rusts, the hoses are rubber and slowly decompose. The scale buildup is seen in hoses when changed show that something is floating around. The coolant filter picks this gunk up and prevents it from plugging up small ports. On other coolant filter threads there is pictures of the coolant filters cut open after being changed. The stuff filtered out is nasty and looks like mud.

Non taken. My post wasn't related to yours.

Cool, No worries

Have a look at this thread: http://www.steelsoldiers.com/deuce-modification-hot-rodding/11143-cut-open-coolant-filter-deuce.html

This filter is cheap insurance for the preservation of your water pump and other engine internals.

Plus, it's one more cool thing to bolt on my truck.

Seems like if I add a valve to block off the heater core inlet then I should get full flow to the filter when the valve is closed and then almost full flow to the heater core when open, with restricted flow to the filter due to the filter's small flow area.

Thanks for all the info.

There's also a really good write up in MVM by Cranetruck on this topic.

 

[joshs1ofakindxj]

I'm hoping he weighs in here because I'm not sure I have my hoses and engine coolant heater in the ideal locations.

 

[russ132]

One thing I was unable to figure out, is if using HD diesel antifreeze (green), and since the deuce does not have wet sleeves, is there a benefit to using the DCA additives?
