Importance of Surge Tanks
Surge Tanks More Reliable Then OE Plastic Ones!
Benefits
- Direct OEM Fitment and Compatibility: Built to OEM specifications, these tanks align directly with factory mounting brackets, hose routings, and sensor ports, ensuring seamless drop-in replacement across major commercial chassis (such as Freightliner, Kenworth, Peterbilt, and International) without costly modifications.
- Superior Pressure and Thermal Management: Designed to absorb internal pressure spikes and fluid expansion during heavy engine loads, preventing localized boiling, air pocket formation, and water hammer effects in the cooling loop.
- Elimination of Cavitation and Overheating: By consistently separating entrained air from the coolant stream, they ensure smooth, bubble-free flow to the water pump, mitigating cavitation damage and hot spots in the engine block.
- Robust Heavy-Duty Construction: Unlike stock plastic expansion tanks that degrade, crack, and leak under severe thermal cycling and road vibration, SouthPOINTE tanks feature precision-welded metal fabrication engineered to survive harsh long-haul conditions.
- Reduced Fleet Downtime and Cost: Long-term fatigue resistance minimizes roadside coolant losses and preventable engine shutdowns, lowering maintenance overhead and total cost of ownership for commercial fleets.
Engineered for the Long Haul: Heavy-Duty Truck Components Built to Outperform
Premium Heavy-Duty Brackets, Heat Exchangers, Air Tanks & Coolant Solutions — Proudly Crafted in Michigan.
When thousands of miles, brutal weather, and intense engine loads push your equipment to the limit, factory plastic and thin-gauge components can fail. At SouthPOINTE Manufacturing, we engineer and build heavy-duty commercial truck parts that eliminate common failure points, reduce shop labor, and keep your fleet on the road where it belongs.
Backed by over 40 years of specialized heating and cooling expertise, our American-made components deliver exact OEM fitment with superior, heavy-gauge durability.
Built for Major Commercial Platforms
Whether you are maintaining a regional distribution fleet, running long-haul sleeper cabs, or managing vocational dump trucks, our components offer verified cross-references and fitment for:
- Freightliner (Cascadia, M2, Classic)
- Peterbilt (389, 579, 386)
- Kenworth (W900, T680, T800)
- Western Star (4900, 5700, 49X)
- International & Mack vocational and highway models
What Fleet Managers & Technicians Are Saying
"We were replacing stock plastic coolant surge tanks every year on our severe-service trucks until we switched to SouthPOINTE metal replacements. Zero leaks, exact bracket alignment, and no more surprise downtime."— Shop Supervisor, Midwest Logistics Fleet
