Caterpillar C32 Marine Diesel Engine Heat Exchanger Plates, Gaskets & Seals
Precision-engineered heat exchanger components for CAT C32 marine propulsion engines—OEM-quality performance, corrosion resistance, and global delivery.
Caterpillar C32 Heat Exchanger Gaskets, Plates & Seals
The Caterpillar C32 marine diesel engine is a 12-cylinder, 32.1-liter powerhouse delivering up to 1,800+ horsepower, with certain C32B models exceeding 2,000 HP. Built for demanding continuous-duty applications, the C32 powers luxury yachts, sportfishing vessels, offshore supply boats, and commercial workboats requiring exceptional reliability and performance.
At the core of the C32’s cooling system is its titanium or stainless steel plate-type heat exchanger, which uses raw seawater to regulate engine temperature. This closed-loop system keeps the internal coolant isolated from seawater—transferring heat efficiently while protecting critical engine components from corrosion and fouling.
MechPro supplies complete C32 heat exchanger gasket kits, plate packs, bolts, spacers, seals, and replacement components compatible with all major C32 variants, including C32 ACERT and C32B. Every component meets or exceeds OEM quality standards to ensure long service life in harsh marine environments.

Product Overview
Heat Exchanger Gaskets
Create a tight, leak-free seal between exchanger plates. Essential for efficient operation and fluid isolation.
Heat Exchanger Plates
Precision-engineered titanium plates maximize heat transfer efficiency, ensuring consistent cooling for C30 engines.
Heat Exchanger Seals
Durable elastomeric seals prevent leaks at joints and maintain proper pressure within the system.
Together, these components sustain optimal engine cooling performance, prevent overheating, and extend engine life.
Maintenance Recommendations
Routine maintenance of your C32 cooling system ensures optimal temperature regulation and engine longevity:
Inspect and clean plate stack every 1,000 hours or annually
Replace gaskets during each teardown to prevent leaks
Flush seawater system with freshwater after extended operation
Check raw water pump impeller for wear or blockage
Monitor coolant levels and maintain correct inhibitor concentration

Frequently Asked Questions (FAQs)
Q: What are typical marine applications for the CAT C32?
A: The C32 is used in luxury yachts, sportfishing vessels, offshore supply vessels, commercial trawlers, and patrol boats, providing high power with proven reliability.
Q: How often should heat exchanger plates and gaskets be replaced?
A: Plates should be cleaned and inspected every 1,000 operating hours; gaskets must be replaced at every disassembly to maintain sealing integrity.
Q: Are MechPro parts compatible with C32 ACERT and C32B engines?
A: Yes—MechPro supplies plate and gasket kits for all C32 variants. Provide your engine serial number (ESN) for an exact match.
Q: Do most CAT C32 engines use shell and tube or plate and frame heat exchangers?
A: Most CAT C32 engines use either a shell-and-tube or a plate heat exchanger, depending on the specific application and configuration. Marine versions of the C32 often use a plate-type heat exchanger for efficiency in a closed-loop seawater cooling system, while some industrial and generator sets may use a shell-and-tube design for the jacket water cooling circuit, as seen in certain generator set configurations.
Plate heat exchangers
- Used in: Most frequently seen in marine applications.
- How it works: Uses raw seawater to cool internal engine coolant in a closed-loop system, which keeps engine components from corroding or fouling from seawater.
- Advantages: More compact and can be more efficient than shell-and-tube designs in specific applications.
Shell and tube heat exchangers
- Used in: Some configurations, particularly for the jacket water cooling circuit in certain marine generator sets.
- How it works: A bundle of tubes is housed inside a cylindrical shell, with coolant flowing through the tubes and a separate fluid flowing around them in the shell.
- Advantages: Can be more robust in very harsh environments and easier to clean and repair in some cases.
