HP5826  Seastar Oil Cooler 

• Offered is our replacement for the HP5826 Seastar Oil Cooler. This cooler is a drop in replacement for the OEM cooler and is guaranteed for fit and function with a 2 year warranty per our terms and conditions. We build this part with equivalent baffling and materials so that it will properly cool your transmission.
• One thing of note is that we use a cast seawater endcap. You may see competitor products offered with a stamped end cap, which are not equivalents.  This cast end cap creates a more stable connection to the cooler resisting electrolysis and corrosion longer than stamped caps.   You might find it easier to obtain access to zincs when replacing them as well. This is a longer lasting configuration and equivalent to the OEM’s design. We have added an additional zinc so that you can optionally use one for a dripless shaft if you would like. There is also a ground stud and a drain which could be used for the same purpose. 

• This part also has a our OEM Equivalent Hard Coat finish and is color matched to what the OEM uses on this part.  A big improvement on the paint that is commonly used in the aftermarket. It makes the part more durable both visually and functionally, resisting surface corrosion. This is the part you want.
