I think it's an easy couple of hours to do a good cleaning of the stack. BUT motivation and outside temp really plays havoc on my time estimates. It's MISERABLE here in the desert SW right now so it's a easy 2-3 day 4-10 sixpack job. <grins>

Hey fellas, it’s been a long while since I started this thread, but I have taken my entire stack apart and cleaned it out, I was surprised what was in there.

While towing this summer on a hot day I was peaking close to 230 engine temp according to the factory gauge. The fan did no engage. And it also did not engage once all winter under the extreme cold temps during “morning sickness”.

When I was backing trailer into the house almost immediately after a steep grade my AC was blowing warm and smelt like engine compartment inside the cab. Never had those before

i cleaned my cooling stack today. it took me about 3 hrs. My stack was not bad at all. I did not pull the radiator or drain it though. It was not easy to get the intercooler out and when I do it again next time i will drain and pull the radiator.

I'm gonna do mine tomorrow. I'm gonna blow em out with a long nozzle for my compressor, the use the wash wand I made to fit between the rads (hopefully).

AxysAssault, I did blow mine out with a compressor from the back too. There was a ton of dust blowing out. There is absolutely no space between the radiator and IC to put any kind of wand in between. I managed to get the intercooler out without pulling the radiator, but I fear it took more time then it would have to just pull the radiator too.

Yea I popped the top shroud off today, then realized it's gonna take a bit more time than anticipated. I'm pretty sure my air wand will fit in between (it's like a 1/4" x 2ft nozzle), but the wash wand will most definitely not. I'll just blow it all out and hit the water from the back of the rad and hope for the best haha.

I should have done this properly when I had the motor on the floor for my head swap.....buuuut it was winter.....in Canada.

Pretty much a waste of time trying to blow it out. Had my radiator out tried blowing first, did nothing. Laid the radiator down flat soak it down with Purple cleaner & let it sit for about an hour. Then did the rinse lather repeat. Mine was plugged in the center probably about 1/4 the surface, right where you need the airflow for the fan to work.
My fan comes on now before the factory gauge hits 210.
