Intercooler cleaner

Intercooler cleanerSo here's the somewhat Heath Robinson device I've made, with Fred's help, to flush out the internals of the intercooler.

This is based on the idea posted anonymously last week.

This picture is obviously taken before filling the system.

You can see the 'header tank' at the top, with pipework leading into one side of the intercooler, and the drain pipe out the other side. You can only just see the pipe from the pump, which is sitting in a bucket, as it loops past the drain pipe valve back up to the header tank.

In the event, cutting the perspex plates and setting up the pipework proved to be pretty straightforward. All this was completed before a slightly late lunch.

I'll post the results of our handiwork tomorrow.

On a separate note, there has been some comment on the piping blanking flanges to and from the intercooler. These have been there like that since I've bought Lady Jane.

My assumption on the blanking plates is that they are there in case the seawater flow through the intercooler needs to be shut off for some reason. Maybe a repair while at sea with the engine running, or blanking off in case of a seawater leak into the engine while under way.

There are a few of these blanking plates built into pipework elsewhere on Lady Jane.

    Gosh, I hope it works -- I feel like my reputation is on the line now!

    It looks like the edges around the perspex are sealed with silicone or something similar. Should hold the solvent allright.

    I'd be curious to see the pump and the fittings on the far side. Maybe next time.

    Once you have the thing full of solvent and the flow going I would think you could just leave it for a few hours and carry on with paiting or what-have-you. It might take some time to soak off some of the crud, but you could easily let it run for hours at a time.

    If you have to actually leave it, I would drain the solvent to a safe container and switch off. The last thing you'd want is for a leak to develop when you're not there to deal with it.

    If any implementation of this crazy idea could work, this one will. Fingers crossed. I can't wait to see how it turns out.

    No problem with your reputation, mine is looking a bit shaky though.

    See today's post :)
