As my title says, so my knowledge on this type of engine is ZERO.

It's a 2000 K3500 dually with 151,000 miles. I got it from the second owner who had it for 10 years. When I buy a new to me truck or car, that calls for a tune up.

I been looking around on the forms and reading on this topic to get a better idea of what parts to get. So far i have

Glow plug- Bosch 0250202253

Injector- Bosch 0432217276

Here is where I need some advice, what brands do you recommend for fluids?
I usually run Amsoil. Im going to drain and flush tranny, rear diff, maybe the radiator.

What else do you guys think I should replace or inspect?

I live in Minnesota so the cold is bad. Is there some where else you would want a block heater? or install a heating pad?

Thank you all for your time!

If you have access to Amsoil, then keep using it.

Remember about the front diff (gear oil) and the t-case (ATF).

Congratulations! I don't know that you can go wrong with any brand of oil these days, as long as its diesel rated. Anything off the shelf is better than what you could buy when the truck was new. Personally I think Amsoil isn't worth the extra cost, but nothing wrong with it for sure. I'd rather use Delo/Delvac/Rotella/whatever's on sale and change it frequently.

If your batteries, starter, cables and glow plugs are in good shape, you shouldn't have trouble starting in cold weather. Just ask some of the hardcore Canadians here who say block heaters are for weenies. :HiHi: It is easier on the truck to preheat it though.

In extreme cold, 5w40 synthetic will help get the oil flowing quicker on startup. Good luck and have fun getting things sorted out!

If you use amsoil, look into their duramax (same dilter as the 6.5)remote oil filter with bypass soot kit... will drastically extend your oil and motor life.

No matter WHAT oil you use, if you have the stock oil cooler lines, ditch them and install a set of replacements from Leroy or lubrication specialists...

You did not say if your trans is auto or manual. If manual you must use special fluid made for the NV4500. You can get it from GM or Dodge. Use of any other fluid will toast the syncros. Amsoil may make a fluid compatable to the NV4500.

Any truck sold in the north seemed to come with a frost plug heater so have a look around for the cord, there may be one there. I just bought a 98 that came from Washington state and the cord is still neatly zip tied from when it was installed new.

15w oil makes for some hard starts when its below freezing but a 5w really helps which I assume Amzoil has as an option.

Are there signs of injector issues or do you know when they were last done?

You should look at the damper. If there are any signs of cracks get it replaced asap if not sooner.

There are a few of us in and around the metro area.

Yes, rebuild or replace every 100,000 miles. Injectors can be the "silent killer". New injectors also help cold starting because they atomize the fuel better. Better mpg is another bonus.
