Intercoolers

[Scarlett]

I pulled my intercoolers for cleaning. It is a pretty easy job, 20 bolts and nuts of which 19 were very easy to remove. One of course was almost impossible to get a wrench on and required me to make up this tool to remove it. Just a normal boat job.

Remember grease on fresh hose connections & Tef-Gel on the machine bolts during re-assembly. Next service will go much smoother.

[Scarlett]

Thanks Ralph, it was very surprising how easy the bolts came out, I guess the last person to do them used your advice.

[Captain Ralph]

So, fill us in; why were they removed? Lots of crust in the raw water side?
Lots of turbo crud on the charged air side?

It was cold and you needed to be abused?

[Scarlett]

Really bad water flow on the outboard side of one engine. I had just done the main HE so I knew it had to be something else and the Intercooler on that side was really plugged up. We have a great radiator shop here that does tons of HE’s.

[Captain Ralph]

It's good to have a local shop like yours.
So many shops are closing up around here.

Keep us up.

[Scarlett]

Just took my intercoolers to the radiator shop where they had maybe 2 radiators and about 30 heat exchangers, many of which were from Detroit’s. I think I am in good hands.

[Dan Mapes]

Would the acid flush have cured that? I used to flush through the whole system except the transmission heat exchanger.

[Scarlett]

Probably would have if it would have been done on a regular bases, but it wasn’t.
