How to clean a marine heat exchanger on Perkins 4108 

I was going to look for a radiator shop to dip mine but now I’m gonna try this🙏

I need to do this soon. Thank you for the video.

thats the concentrate supposed to dilute it.. that bottle is 70$

Could u do while the heat exchanger is still on boat bolted on

"not too bad, almost..." can I quote you ?

if you are going to do it in situ - flush through 45 mins one way - and then reverse the cycle for 45 mins in the alternative direction

Is that the zinc that was bubbling for so long?

Toilet bowl cleaner will take every bit of this stuff off.

Looks like the Anodes are either non existent or need attention. Hydrochloric Acid and water (1 Acid - 10 water) can be used. Just like doing a pool salt water chlorinator.

Why do you keep calling this bunker buster. The text above calls it by its proper name, Barnacle Buster. Had me confused there for a bit...

Is this a Sen dure heat exchanger?
