Had this Idea 4 months ago. I'm one of those guys how has to sit down and put it on paper first. I ve tried a couple of pumps . But right now looking at a gear pump. The 5/8" Line transmission coolers works good. But flow rate with diaphram pump is not consitent. Still working on it. I love this stuff! Sorry don't mean to rain on anyones parade. Just love these's concepts
Even if the flow is inconsistent, it hast to be relative to engine speed, and somewhere upwards of 35 gal/hr to keep up with what it was intended for.
Just buy synthetic oil it is cheaper than all that...

While synthetic may be cheaper, a 20' stretch of 1/2" tubing can be had for free at work, And I could flush my transmission cooler and use it when I do the T19 swap, so i'll be out $30 for the new lift pump because my old one was toast. So it's really more of a time thing than a money thing.
Can the oil be too hot for the diaphragm? Excellent idea, I do believe I shall do that for my zf though.
Thats part of the beauty of the idea, if it can't, and the diaphragm pops, all that will happen is the oil will go into the oil pan! If it happens more than once though, I'll start looking for different pumping ideas.
i can't think of why you shouldn't do this.it's interesting! normally you can't run the smaller lines/coolers for oil due to too much restriction,but you'd have your own devoted pump,so it wouldn't matter i guess.
for winter,you could just unhook it.
do you know what your oil temps are now?
could a little lift pump flow oil fast enough through a trans cooler to make any difference at all anyway? i guess that's the question.
that's a really frigging neat idea.
I use the heck out of my block heater in the winter, so imho that shouldn't even be an issue. The pump in it's intended use pumps 35+ gal/hr at 7psi through a 3/8" fuel line, thats more than half a gallon a minute, granted I'll be using bigger lines, it would likely be more, and it's flow rate is entirely dependent on engine speed, I think flowing half a gallon a minute trough a cooler would help a lot, it will just be one more way for the engine to shed heat, so it can't possibly make temps hotter. It would also add capacity, about 4 quarts actually iirc, so that will help too. I don't have accurate temp readings of my oil right now, but often shoot different areas of my truck with a temp gun at work when I get there, and have seen 220* on the oil pan! Thats when I decided some sort of modification would be nice.
Understand that I'm not doing this because I think my oil itself is getting too hot, but because I know that the oil carries off engine heat with it, and does a better job of doing that when it's cool than hot. It will take a little bit of a load off the coolant system, and allow me to work the truck a little harder before I start to worry. The oil probably lasting longer, and giving a better service while in the engine is just a happy side effect.
