Flushing engine

[Dave Galehouse]

6 CTA Cummings – I flushed my engine a few weeks ago with barnacle buster. Last weekend I wanted to take a peak inside the heat exchanger and replace the end cap gaskets. It was pretty clean but my assumption was that the heat exchanger always has water in it. Since it doesn’t, what’s the best way (without removing the heat exchanger) to flush it if barnacle buster isn’t actually staying inside the heat exchanger?

Disconnect hose off your raw water pump, and also your hose exiting the heat exchanger. Rig a temporary hose and circulating pump between those two lines with a bucket of barnacle buster or ryde lyme or whatever plumbed into the loop, and circulate the goodies in the system for several hours.
