The Right Heat Exchanger and Manifold for your Perkins Engine

For Pricing Please Inquire Below.

Perkins Heat Exchangers and Exhaust Manifold Assemblies, Bowman Heat Exchangers and Manifolds are IN STOCK & ON THE SHELF at Trans Atlantic Diesels. We have specialized in Perkins Engines for 35 years for which we carry a comprehensive range of cooling components, parts, and Bowman products. That gives us the experience that others don’t have to help you with your Bowman replacement, or retrofit/upgrade. Don’t wait for your parts to be shipped across “The Pond” and delayed in customs. We normally ship same day from our shelves, with competitive pricing.

We also can order Bowman cooling components for many engine lines including: Perkins, Ford, BL British Leyland, Cummins, and others. Call for availability on engines not listed.

We don’t just sell, we service. We have the expertise to help with installation questions; we can also supply the necessary gaskets, hoses & hardware with our retrofit kits. These are typically used in cases where the original part may be no longer available.

Streamline Your Engine

If your Perkins 4.108 - 4.154 (Standard Equipment) - 4.236 - 6.354 is currently fitted with separate cooling components (i.e.: Header Tank, Wet Manifold and Heat Exchanger) and is in need of replacement, consider retrofitting the Bowman Combined Manifold, Header Tank and Heat Exchanger all-in-one unit. This will streamline your engine, giving more room in the engine compartment for engine accessibility.
