So if you have your motor out or have a coolant leak check your hoses, I just got this damn sled put together only to find I had a coolant leak. I pulled the motor out and inspected everything, it turns out the leak was from the hose that run from the bottom of the coolant bottle to the back of the motor aka the water pump. Right where the hose has premolded bends in it is the problem are, I have a few 900 motors laying around and 2 out of 3 were worn out or showing signs of wearing out.
