Precision Cleaning and Restoration
Without the Marine Markup
When it comes to marine engines, keeping your heat exchanger in top condition is critical for performance and reliability. At Welshpool Auto Service, we provide full-service overhauls for marine heat exchangers – without the inflated costs often associated with marine-specific workshops.
Whether you operate a small commercial vessel or a recreational cruiser, we can help maintain the components that keep your engine cool and protected.



Our Process
Every marine heat exchanger we service undergoes a thorough multi-stage overhaul:
- Hot Wash – To remove oil, salt, and grime.
- Disassembly – Complete teardown to access and inspect all components.
- Vapour Blasting – Safe, effective removal of corrosion and buildup from metal surfaces.
- Ultrasonic and Chemical Cleaning – To clean internal galleries and fine passages.
- Flow Testing – Ensures coolant moves freely through the core with no obstructions.
- Reassembly with New Gaskets – To OEM standards or better.


Why Overhaul Your Heat Exchanger?
- Prevent Overheating – A blocked or fouled core can cause serious engine damage.
- Improve Efficiency – Clean surfaces mean better heat transfer and engine performance.
- Avoid Expensive Replacements – Restoration can extend the life of original parts.
- Quick Turnaround – We know downtime costs money, so we work fast and efficiently.
