'86 Jimmy 4in Lift, 40’s, tons, 8.1 Swap- 700r4 said PNNNNN

This is not a dedicated trail rig, but does trailer to the destination usually. I am currently in the planning phase of doing a 52/56" spring swap, and getting back to being more road worthy.
And no, Roadkill was not an influence. I hadn't heard of them at the time. I blame Farmshow for my questionable ideas. :haha:
Haha. Farmshow. It was interesting to say the least. Great reason why farmers have questionable reputations! Dean didn't help anything earlier either! @max 02

Have you know I had a plow pump quit working one night about 2-3am, I was able to hotwire it with a scotchlok, and it kept me plowing until 7-8 in the morning when I was done. That little connecter probably cost .11 cents and made me 500+!

Any repair that gets you home is a good repair. But the minute you finished plowing, it became hack work. :haha:

Or it worked so well I kept it there, apparently the power wired that was done correctly failed.

Food for thought.
 
I'm loving this dialog. It's how my brain thinks too.

Most of the stuff I am fixing are things that were "trail fixes" or "hurry to get it going for the weekend", but then they just kept working and they never got corrected.
 
Dumb question...if you're using a Workhorse hose, what are the odds of finding a replacement when on the side of the road? I'd think the odds are pretty slim. :dunno:
It's really easy. Ask for a lower hose to any big block squarebody truck and you'll have what you need.

The workhorse and medium duty accessory bracket uses a water pump with the standard big block outlet they have used since 1965. In other words that hose is almost as common as the flex hose.

It's another bonus for using those brackets over the stock gmt800 setup he has now. But given the rarity of the workhorse brackets what he has done is a viable option.

I think I have never met a temporary repair. That ratchet strap has been on there so long I'm back to thinking about another engine swap. At which point I won't need that exhaust setup anymore.

That "temporary" exhaust strap might outlast the whole drivetrain! :eek1:
 
On those flex hoses, I always wondered how much the flexy bits hurt the coolant flow. Enough to noticeably effect temperature??

I agree bout the comp being a smidge close to the radiator outlet, can you move it to the other side of the bottle closer to the hood hinge?
 
I would bet that the heat is higher farther back. The fan blows heat towards the firewall, and the exhaust heat is back there too. There won't be a great amount of airflow behind the headlight, but the heat sources ahead of it are low.
Factory Duramax trucks have the TCM mounted on the back of the fan shroud.
:dunno:

This is what I based it's position off of. And it's high enough that if my top headlight is under water, I am going to be having more issues than a wet ecu.
 
Also, the radiator is at least 8" away from the ECU. I'll get a different angle on the picture tonight.
 
I just checked out the company truck to remind myself. It is only a 6.0 truck, but still. It sits lower than you have yours positioned.

I can tell you, no they don't effect coolant flow at all to effect temp. I have those universal hoses on the upper and lower radiator of my 8.1 swap that only see's tow duty. Even towing the below load (estimated about 17K GVW), it never got above 190*, even on hills.

You gonna do a build thread on that green machine you're building?
