Imagine this: You just spent money replacing the new coolant pipes, thinking the problem was solved. Three months later, the radiator starts leaking; two months after that, the coolant reservoir cracks. Your Dodge Ram keeps running to the repair shop, disrupting work schedules and towing plans.

This is no coincidence. For owners of 2013–2018 6.7L Cummins diesel vehicles, the cooling system parts are designed to age together. Thermal expansion and contraction, high temperatures in the engine bay, and vibrations from long-term towing cause the factory plastic pipes and rubber radiators to fail prematurely. Replacing them one by one not only triples the labor costs but also leaves the vehicle unavailable for days on end.

Why do cooling parts age together?

Every time you drive with a load, climb hills, or tow a camper or work trailer, the cooling system is under stress. Coolant circulates thousands of times a year between the lines, radiator, and reservoir. Plastic becomes brittle, and rubber hardens and cracks. Parts that worked fine at 60,000 miles may start thinning in the radiator, leaking in the hoses, or cracking in the reservoir by 150,000 miles.

Instead of waiting for parts to fail on the road, fix it all at once.

SPELAB Cooling System Update Kit: Replace once, enjoy peace of mind for years

This kit, designed for 2013–2018 Dodge Ram 2500/3500 6.7L Cummins, has a simple core logic: replace the three parts most likely to fail together at the same time.

• Upper Coolant Pipe: Replaces the factory plastic and rubber lines. This is the most problematic area on this generation of vehicles, long exposed to high engine bay temperatures. SPELAB upgrades it with more durable materials.
• Aluminum Radiator: The core heat dissipation component of the entire cooling system. Compared to the factory radiator, SPELAB’s aluminum radiator provides more stable cooling performance. Professional installation by a technician is recommended.
• Coolant Reservoir: Manages system pressure and coolant expansion. It’s a small part, but if it cracks or leaks air, the entire system’s pressure will be disrupted.

The kit also includes all necessary mounting clips, connectors, and other accessories—no need to hunt for parts separately. Colors available in black, red, and silver to match your vehicle’s style.

One installation saves three downtime periods

From a cost perspective, the kit’s logic is clear:

• One service replaces three separate replacements’ labor
• Completed in one day, no need to visit the shop multiple times throughout the year
• One-time expense, avoiding a series of unexpected repair bills

If you use it for towing, hauling, or earning a living with this vehicle, this “predictability” is the greatest value. You no longer have to guess which part will fail next—upgrade the three most likely to fail at once and continue driving with peace of mind.

Pre-installation reminders

This kit isn’t plug-and-play. After installing new parts, the system requires complete bleeding and refilling with coolant, which is standard procedure for any cooling system work. SPELAB also recommends professional installation (especially for the radiator section) due to the extensive coolant handling and steps involved—leaving it to experts saves time and hassle.

Additionally, this product is positioned as a “durability upgrade,” not a horsepower increase kit or a performance mod guaranteeing temperature drops. Its value lies in replacing the three most failure-prone parts before they break, avoiding future roadside breakdowns or high unexpected repair costs.

Who needs this cooling system update kit the most?

• 6.7 Cummins owners with over 100,000 miles
• Users who frequently tow campers, construction trailers, or heavy loads
• Those who don’t want to replace parts one by one and want to solve the aging cooling system issues all at once
