Flushing motor

[Pocketfisherman]

Restricted fuel flow will sound the same alarm horn as overtemp on many makes of motors. Next time it happens, try squeezing the priming bulb and see if that makes it stop.

Use build up buster or other similar acid wash. Gunk builds up in the cooling passages over time and restricts flow. Water pressure will be fine but the flow is restricted, kind of like atherosclerosis in your coronaries. Acid flush once a year cured a similar problem for me.

Don't know about your gunk problem but have always been a believer in Salt Away type flushes. I do my own water pump impeller replacements and Zinks in the block and they are pretty clean.

my mechanic told me to squirt some dawn dish soap or salt away in the hose before attaching to motor. Run motor until it stops throwing soap

Now I am wondering how often something like this happens.

I had flow issues with the motor on a boat I picked up close to 3 years ago. I decided to flush it myself so I pulled the lower unit and thermostat. Then I rigged up a continuous pump to run some Simple Green lime scale remover through the water jacket for about 3 hours. I saw lotsa trash come out and noticed that it did seem to pee a little stronger once I got it back together.

Then I got it out on the water and ran her. Started out fine, but then I noticed a loss of power. I figured I had a carb issue. Nope, turns out I scorched a piston.

Not sure if flushing the motor caused the issue, but definitely makes ya go hmmmmm?

Muriatic acid???? Sure that isn't good for the gaskets or gasket goo if you had goo used by a lazy mechanic that didn't have the seal kit on hand. That stuff eats concrete.

This is what I am wondering. I flush with the salt terminator 1 in every 3-4 times out. THen about 1 time year I put it in a large ice chest and run it the motor with about 1/3 bottle of the stuff along with some vinegar. Always have some debris in the bottom.

But this does this does not clean the green gunk out. I am wondering if a degreaser like dawn would break it up and clean it out even more...

You can pull the thermostat and take a tube of Lime away ....squeeze half down each hole

Give is 10 min then flush .... easy way to get crud out

i suppose you don't change the oil in your vehicles either? but run them til they're empty and then refill, similar to the windshield washer reservoir???

Oil is overrated. &#x1f61c;
