Hose can be had from Macmaster Carr. The injection elbow itself. 316L stainless ones can be had for the same price as the black steel Westerbeke one. As mentioned fabricated your own nipple
Hello Everyone!
Following up on the coolant ‘leak’ and possible heat exchanger replacement:
As noted previously, I took a risk and ordered a new heat exchanger. without testing the old one. Mr. Cool’s customer service was very good, and answered some questions/provided good input/clarification on 1 or 2 follow-up calls. One call involved using the brackets that came with the new heat exchanger - I wasn’t clear on how to attach them. The Mr Cool rep was very patient while explaining how to configure the new brackets to replace the old brackets. However, one bracket wouldn’t work without modification as the engine housing blocked the bracket placement and I would have had to perform some surgery on the bracket to remove some of it’s corner to make it fit… I decided I would re-use the original brackets if I could get them off of the old exchanger… they are solid brass, but I was able to spread the arms far enough apart, using just my hands, to get them off of the old exchanger and onto the new.
After figuring out the bracket issue, everything else went smoothly and I used the correct size tailpipe (no need to step down hose sizes) that I ordered from Nassau National Cable (price was right, though shipping took a little longer than expected (surprising as they aren’t that far from where I live).
Ran the engine (sometimes with some load) on multiple occasions for an hour to two hours each time, and coolant level remained stable (and no leaks)!
Here are a few photos of the old exchanger coming out, and the new one going in:
Had to move (but left all connections in place) the fuel pump (black cylinder w writing) to get to the heat exchanger - luckily, not difficult
The original heat exchanger brackets - 1 with 1 without the bolt in place.
Old exchanger removed
Old exchanger out! Couldn’t get the old tailpipe (left side facing camera) to budge… glad I ordered a new one!
New exchanger in place with hoses reattached (except for new tailpipe (left side) hose that goes to the
transmission oil cooler - did that after this photo was shot), Fuel pump et all re-mounted.
Again, thank you to those who supplied input for this venture!
