So, I tore apart one of my pumps today since it apparently wasn't working ...

I have the dreaded D45 red light and I cannot seem to solve the issue. I know its not the the thermal paste - successfully changed that on other TMs with no issue. I used a mechanics stethoscope to listen to the pump and it seems normal, shows a normal RPM on the STATS page but for whatever reason (according to the diags) the cores overheat and immediately shuts down one board. Tried swapping the connectors, pulling the J11 and a few other things but no luck...

For what its worth, I haven't taken apart the other side of the pump since I didn't have fluid to replace what I would have lost had I done so. Does anyone know what type of fluid it uses? Perhaps I'll try that and take some pictures next.

Hi,

I have had 3 radiator hoses spring leaks over the past few months so this is what I did- and I think it keeps things even cooler than the stock coolers.

To replace a leaky hose, remove the entire radiator / cooling block apparatus. Place it on it's back with hoses facing upward and cut off the leaky hose (you will loose no more than 10 ml of coolant, the precise amount is not important). Go to your local hardware store or Home Depot and buy a length of polyethylene tubing. Its the same hose that is used on your refrigerator ice makers or if you can find what Cointerra used that's ok too but the polyethylene is much, much stronger so it's never going to leak again. Cut the correct length and replace the hose but...

Connect the 1st end to the radiator and before you connect the other end to the block, fill the radiator up with as much "automotive anti-freeze". If you want to dilute the antifreeze with a little distilled water you can but its not necessary as most all antifreeze comes already diluted. After the radiator is filled up with as much antifreeze as will fit, attach the other end of the hose and replace the radiator back in the miner. A few air bubbles are unavoidable and does not affect the miner operation that I can see. My refitted automotive antifreeze miners all run on power level 9 with temps running in the mid to high 50s deg C.

Hope that helps.
