In diesel engines, small diesel engine problems don’t stay small.
A slight drop in oil pressure. A little smoke at startup. A minor coolant leak. An injector that’s “just a little off.”
These are easy to ignore, especially when the truck is still running.
But in heavy-duty diesel engines, those early warning signs are not minor inconveniences.
They are the beginning of a much bigger failure.

Older Cummins engines – especially Big Cam and NTC/N14-era platforms – used two different cooling system designs:
- Low-flow cooling systems
- High-flow cooling systems
These systems are not just minor variations.
👉 They are fundamentally different in how coolant moves through the engine.
And that matters when you’re trying to solve overheating – or considering a conversion.

If you want to prepare your diesel truck for winter, it starts with understanding how cold temperatures affect your engine, fuel system, and overall performance.
Cold weather introduces challenges that diesel engines are particularly sensitive to, including fuel gelling, reduced battery performance, and increased wear during startup.
Preparing ahead of time helps prevent breakdowns, hard starts, and costly repairs.

Diesel engine belt noise is one of the most common drivability complaints on heavy-duty trucks and equipment.
The noise may sound like:
- A squeal
- A chirp
- A screech
- A grinding or growling sound
However, the belt itself is not always the actual problem. In many cases, the noise is caused by:
- Improper belt tension
- Pulley misalignment
- Worn bearings
- Oil contamination
- Failing accessory components
Accurately diagnosing diesel engine belt noise is important because replacing only the belt may not solve the root issue.

If you’ve already invested in diesel engine parts, you already understand how critical performance and reliability are.
But there’s one system that impacts everything else, and it’s often overlooked:
Your lubrication system.
Clean oil is not just about maintenance. It directly affects how long your components last and how efficiently your engine operates.
