i had coolant temp spikes 230-240 real quick and fast on the hills and long duration time with the engines cooling fans after a front mount intercooler and a large aux trans cooler were stuffed behind my grill in July and August. (well,i solved the issue in aug.)
I got to thinking,why the fast spikes? so i thought about it,and said,ahh i betcha my oil temps are getting too high (no gauge) and transfering over to high coolant temps.so i pull over at the top of a few grades after towing and hauling heavy with my truck and dump trailer and shoot the pan with my point and shoot gun and sure enough,260+ oil temps!!! and that was just a couple medium grades.no wonder.that's too much of a job to ask from the engines cooling system alone,
so i installed an aux oil cooler and moved my aux trans cooler and it solved my coolant temp spikes and long e-fan duration times nicely back in the heat of summer.
here is my setup with part numbers:
Earl's Performance Temp-A-Cure 16 Row Oil Cooler #41610A
Mocal 200 Degree High-Temp Remote Oil Thermostat #MOC-10ANHT
Perma-Cool Spin-On Oil Filter Adapter #2840
Hy-Lube 1.5-16 Remote Oil Filter Mount
Parker 426-8 ( 1/2" ) High Temperature Hydraulic Hose w/ Jic (AN) Fittings.
i didn't want to move my oil filter for anything,but do you think i could source a basic aux oil cooler/filter sandwich for the ever so popular 7.3l? not for the life of me! i couldn't believe it!
then hy-lube remote filter head was the only oem thread size so i could keep my large filter (most run the fl1995 motorcraft.i run a larger synthetic type with same threads mobil m1601) so i had to pay big too keep that too.
i was/am totally floored at the lack of 7.3l support for aux oil cooler and remote location filter heads and goods.unreal.especially since the 94.5-97 psd share the same filter thread.
i figured for such a popular engine,i could easily choose all kinds of options.i figured id just buy a oil filter sandwich with a/n fittings complete with t-stat and all like popular gas engine choices.....oh no.that would have been too easy and too affordable.no one even makes a basic sandwich without t-stat and basic npt ports......nothing.nada.crazy! so it really costs some coin to keep things "right".aww well,like the old saying goes; if it was easy everyone would do it.
pics attached.
as you can see i mounted two coolers down below the front valance behind a sheet of 1/2 wire screen stock (or whatever it's called.found locally at hardware store.)
it sets up above the front axle and mounted above fisher plow mm push plate cross bar (i know,how convenient) it is not an off road truck (well.on grass or plowing snow,but no running through the woods or trails of course lol.)
the larger rear cooler is a tru-cool aux transmission cooler (on a 180 t-stat - not shown.)
the smaller front cooler is the aux oil cooler (on a 200 t-stat - shown in pic.)
the results were fantastic.
at first i simply did the oil cooler and that cured all that ailed her really.
then i thought well how much better if i ditch that massive aux trans cooler from in between that massive 3" thick front mount intercooler and move that right down with my aux oil cooler.
then that helped even a bit more to reduce the electric cooling fan run time without that blocking air.though that was fairly minimal compared to just the aux oil cooler.the oil temps was much more of the issue than too many coolers stacked behind the grill but both went hand in hand nicely.
no more fast high spikes when at max gross pulling grades.
