You can't measure temperature at a dead end, it has to be somewhere with flow. It's easy to get the pan off the truck. Put the temp sensor there. I will repeat, however, oil temperature is unimportant on these engines. If you want to know the oil temp, just add 10°F to the coolant temp.

It's in a difficult spot to see. It's on the passenger side, behind your alternator next to the timing cover, just below where the head meets the block. I actually permanently tapped mine with a stainless steel tube so I can get oil pressure from it.

The threads are not the sealing surface in either inverted flare or tube-o. You must use the correct fitting geometry. The female inverted flare fitting has an angled seat that the tubing bottoms out against. This is where the seal occurs. The Tube-O female has a pilot that an o-ring slides...

If the threads did engage where is the seal going to happen? The fitting on the truck has an o-ring, inverted flare does not. Also, the Tube-O fitting on the truck is 3/4-16.

The transmission lines are inverted flare. The oil cooler lines are "Tube-O" fittings. They use an o-ring to seal. The correct hose end for the oil to connect to the oil cooler is Parker 15G26-8-8...

Don't forget to get the busting strength is much bigger than the unbusting strength on impact wrenches. I suggest observing the amount of rotation required to loosen a properly torqued fastener and observing this rotation when tightening by impact. With heavy duty diesel engines a lot of...

Veggie oil also turns in to paint as it oxidizes. That makes your cast iron pans non-stick but it's not so good for engine surfaces. Vegetable oils were the first alkyd enamels.

There are a couple of major drawbacks to running oil. It's very viscous and tends to flow laminarly instead of turbulently. This means boundary layer are very thick and they act as insulation preventing heat transfer. Oil has a very low specific heat. More oil has to be pumped through the...

Just remember that anti-seize is meant to protect from galling during the tighten of fasteners. It is not primarily intended to prevent corrosion or wear. There are other products that work much better.

I always despised the international symbols. I can Google a word from a foreign language that I don't understand but I can't Google a symbol.

Try the 734...

You can buy it from McMaster https://www.mcmaster.com/standard-electrical-wire/mil-spec-wire However, for vehicle wiring it's a but stiff. SAE J1128 or J378 are better suited standards.

I like the 734 because it's low viscosity and flows to cover the connection more neatly.

If you want RTV use Dow Corning 734. If you want grease use Dow Corning 111 If you want upgraded grease use Ulta Safety Systems Ultra Tef-Gel.

A straight driveshaft is not necessarily a good thing. In fixed applications it's standard to build 7-15 degrees of offset into cardan shafts because you need oscillating motion to keep them lubricated. My experience is transmission between to fixed locations.

If you don't buy a heavy duty "conventional" coolant you're supposed to add SCA on the initial fill and again every 300 hours or so with a change at 3000 hours Conventional coolants are available to purchase through Caterpillar but not many other sellers even have it. Heavy duty ELC coolants...

Something to keep in mind, whatever antifreeze formulation you use, they cannot protect dirty metal. The corrosion inhibitors are film forming additives that react with the metals to produce the protective films. Rust and other dirt will prevent the formation of protective film and the corrosion...

No, SCA does not affect the freeze point. Count the SCA volume as water. Do not use SCA with organic acid technology coolants (extended life coolants). https://www.fluidlife.com/blog-coolant-effects-of-sca-on-elc/

Well nuts are able to be installed in blind holes. If the hole is 3/4" diameter the 3/8 well nut is a drop in. No special tools. Well Nuts, 3/8"-16 Thread Size, for 0.015" to 0.437" Material Thickness https://www.mcmaster.com/93495A441

Food for thought, control modules with batteries are typically designed for a 25 year life expectancy. That can get much shorter at higher temperatures. I have successfully replaced batteries in one specific control module.
