What This Part Is
R024006A is the genuine OEM 90° elbow fitting used in the cooling water circuit on compatible Crusader and PCM marine engines. It connects a 3/4 NPT threaded port to a 1 in. cooling hose and is typically found in the thermostat housing area or engine water routing plumbing. Confirm fitment from the engine parts diagram for your specific model and serial number.
Compatible Applications
- Crusader and PCM (Pleasurecraft Marine Engine Group) marine gasoline engines where the parts diagram specifies fitting R024006A
- Cooling water circuit plumbing requiring a 3/4 NPT male × 1 in. hose barb, 90° elbow
Serial Number & Fitment Notice
Verify fitment using your Crusader or PCM engine serial number and the corresponding parts diagram. Cooling system fitting specifications vary across engine configurations and production ranges. There are multiple R024-series elbows with different thread sizes and barb diameters — confirm the exact part number from your engine diagram before ordering.
When This Part Needs Replacement
- Fitting shows cracks, corrosion, or thread damage
- A coolant leak is traced to this fitting or the hose connection at this location
- The hose barb is damaged or the hose no longer seats securely
- Cooling system overhaul where all fittings are being inspected and replaced
Installation Notes
- Use a thread sealant rated for cooling system applications (such as PTFE tape or a liquid sealant compatible with antifreeze) on the NPT threads
- Do not overtighten NPT threads — follow the torque specification in the Crusader or PCM service manual
- Inspect the mating hose and clamp during installation and replace if worn or cracked
- Confirm the 1 in. hose barb matches the inside diameter of the hose being connected before assembly
- Pressure-test the cooling system after installation and check for leaks before returning to service
Technical FAQ
What is the difference between R024006A and other R024-series fittings?
The R024 series covers several 90° elbow and straight fittings used throughout the Crusader / PCM cooling circuit. Each has a specific thread size and hose barb diameter. R024006A is a 3/4 NPT × 1 in. hose barb 90° elbow. Confirm the exact fitting required for your location by referencing the engine parts diagram for your specific model.
What thread sealant is appropriate?
Use a sealant rated for engine cooling systems — PTFE tape or a liquid thread sealant compatible with antifreeze/coolant. Avoid sealants that may contaminate or degrade cooling system components.

Parts Desk Insights
Best use case: R024006A is the correct OEM choice when a cooling water leak is traced specifically to the 3/4 NPT elbow in the Crusader or PCM engine cooling circuit, or when all cooling fittings are being replaced as part of a scheduled engine overhaul. Using the OEM part ensures the correct thread specification and barb size for a leak-free, long-lasting installation.
Common issue: The most frequent ordering mistake is confusing R024006A with other R024-series elbows in the Crusader / PCM cooling system. Several fittings in this range look similar but have different thread sizes and barb diameters — none are interchangeable without risking leaks or hose fitment problems. Always confirm the exact part number from the engine parts diagram for your specific model before ordering.
