My perkins T6.354 was running a little hot, about 195, up from the usual 180.
The strainer was clear, the impeller was good. Today I ran some Rydlyme through the raw water side. While I was doing this I also changed the thermostat. To change the thermostat I drained the coolant from the tank. It was green and looked good.
I also got a new 7lb coolant tank cap. The cap was not on the tank while the rydlyme was running.
After a while I noticed the rydlyme/water mixture in the bucket was about one gallon lower than when I started. I looked in the coolant tank and it was almost full. I put the cap back on the tank and continued to run the Rydlyme. The tank did not overflow.
When I finished with the Rydlyme I did a flush with fresh water, put the impeller back in, and hooked up all the hoses.
I also emptied the coolant tank again. This time is was not nice green coolant but somewhat like a light brown water.
I have not refilled the coolant tank and have not run the engine.
I am thinking I have a heat exchanger problem that has let raw water into the closed coolant side.
Any suggestions on what I should do next, or if I did something wrong when I was flushing the raw water side?
