Close to my setup.

 

looks good fuzzy.the cleanest bypass type setup iv seen.i could live with that,should i notice a drastic loss of heat in the cab come winter,with a fresh filter.
got mine hooked up.
no bypass.still hurts the hand when you hold it right up to the vent on high heat.now when i notice a lack of really hot air in the cab,i'll know to change the filter.works for me.


side note;
look at the crap in the pre-filter/screen on my e-pump.
i have dual poly tanks and complete rubber fuel line.that crap came from the pumps where we pay $4 plus a gallon for.nice uh.

 

That should work. I change mine every other oil change.

 

Since this is all about cooling systems, can i put a shut off valve in the hose to the heater core to keep it from heating up?

I dont want to cause a "blockage" if its gonna hurt something...

 

yeah.you can block the heater core right off for the summer.
this is often done on older trucks where the blend door seal has deteriorated.

 

Hey XLT, you could have at least tried to match the filter head paint.

 

lol nah.im not that picky with this old work truck.

 

Well, im missing half the box under the hood, so im trying to cut down on as much heat as i can... :/

 

haha yeah.i used to have a car like that.i hear ya.

in fact the car i have now ('96 t-bird) has a blown heater core.you know where they put it? right directly in the center! you have to rip out the seats so you can pull the entire dash out!
no thanks.the fix; a buck and a hose connector.no heat,but who cares.she's totally worthless on snow anyway lol.

 

Otahyoni,
You can plumb in a bypass valve and hook it up up to the vacuum line for the recirc air damper. Then only when the A/C is set to Max the heater will be bypassed. In this way the filter works in the summer as well.

 

I did this using a bypass valve with the hoses and clamps off of a mid 90's Ford Explorer.

 

New the part is about $15. Mine is off a late model ranger. I have it on my '87 Bronco, I am trying to also rig in a vacuum solenoid and hook it to the AC compressor switch. That way it bypasses only when the A/C is on - not just when it is set to Max. Still have not found a cheap vacuum solenoid... working on it.

 

I might do that eventually, if the vacuum even works.... For now though i just want it shut off for this weekend...

 

7. What is meant by the term Fill-For-Life technology?
The Fill-for-Life alternative provides for easy, low cost monitoring of the coolant inhibitor and freeze protection levels. Fill-For-Life is an extended service maintenance program developed by Fleet Charge and Penray researchers. It is very simple. Users simply install a Penray Need-Release filter on an engine coolant system (up to 30 gallons). Every 18 months the filter is replaced. This practice eliminates scheduled coolant changes.
Fleet Charge Frequently Asked Questions

attached in the pdf's below:

Need-Release® filters now last 150,000 miles, 15 months, or 3,000 hours!

The Need-Release filter is a high-durability system that contains an exclusive, patented, membrane-release technology. As the
coolant ages, the Need-Release filter responds to the changes in chemistry in the system automatically. As the membranes
corrode, specially formulated SCA chemistry dissolves in the coolant, restoring the cooling system to an optimum environment
that guards against scale, corrosion, and liner pitting.

so i sent an e-mail to penray asking them which filter would screw into the napa 4019 which takes these filter specs:



PARTS DETAIL
Principal Application: Cooling System Filter with No Chemicals
Style: Coolant Spin-On Filter
Service: Coolant
Height: 5.214
Outer Diameter Top: 3.694
Outer Diameter Bottom: Closed
Thread Size: 11/16-16
Burst Pressure-PSI: 200
Nominal Micron Rating: 27
Note: Service: SSI

hopefully will hear back from them with good news soon.
what i'll do is use my current napa filter for another month or two,and remove it and cut it open to see if its real nasty.if so,i'll throw another one on for a few more months and then inspect that one.once i have clean results,then i'll install the penray filter and run that,provided they have one for this filter head.

well penray never did reply to my e-mail.but looking around a little, it appears 11/16 - 16 is what detroit diesel uses.but im not 100%
NF2088
Fits standard filter bracket for Detroit Diesel, Caterpillar, Cummins, Ford, etc. engines. Compatible with an 8-20 gallon cooling system capacity that has been pre-charged with 1200-1400 PPM nitrite.


and here is another one that works the same way as the penray "Need Release" but called "Additive Replenishment
Technology" for those interested.
it's called a Donaldson Endurance™ PLUS
the part number for the 11/16-16 thread is #ECF4088
you can read about these filters here:
http://www.donaldson.com/en/engine/s...ary/000376.pdf

baldwin has one as well.they simply call theirs "Controlled Release."

http://www.baldwinfilter.com/literat...ts/Form337.pdf

im not seeing how this differs from a napa/wix w/ set amount of sca though.not seeing what controls the limit of additive entered.hmm.

well interesting.seems they all may have a slow release type.here is the wix/napa 11/16-16 thread "need release" part #'s
(most likely not found in stock,but im sure they could order them in at your local napa.but if your going to do that,might as well skip the middle man and order it online yourself lol. ) :
Wix 24088 & Napa 4088 Coolant Filter
http://www.fleetfilter.com/filter/wi...ers/24088.html
though im not finding info on their technology on how they go about slowly releasing as needed.

one things for sure,you can't beat double checking these filters via test strips just to make sure they're releasing properly for you.
i wouldn't run one blind.

so you can have a complete long term trouble free coolant system like more modern diesels do by using ELC coolant,while keeping the proper recommended type coolant these older diesel coolant systems call for.
however,id do what im doing first.since the napa/wix or other standard 11/16-16 thread coolant filter of your choice are much cheaper,you may want to clean out the system with these,to get the old system flushed nice of corrosion/poor maintenance from previous owners and just to clear out the bulk of the sand casting before you spend the $ on a pricey need release type filter, that will last a long time filtering,and maintaining the proper levels of SCA/DCA for you as required.
