I swapped out the radiator the other day and today filled it with coolant/distilled water. I fill from the reservoir until full then I pull the upper hose off the radiator then fill it into the hose until fill then reattached. I then started it up and ran it for probably 10-15 minutes. Temp rose steady till it hit the normal operating temp on the gauge. I then took it out for a test. As soon as I pulled onto the street temp started climbing. I immediately pulled back into the shop. Nearest I can figure is I thought I got it full from the top hose but must not have. I could not feel any water in the hose when squeezing it. I then loosened the cap a little and it had quite a bit of pressure enough to where fluid started coming out. I ran it for a few minutes on high heat before doing this. After releasing enough pressure I pulled the upper hose in again and it was dry. Filled in a whole gallon of distilled water in there and topped off the reservoir. Started it back up and it did not start getting hot but after a few minutes with the cap left off coolant started rising up and flowing out of the tank. Shut it back off, pull the upper hose again and it still appears to be dry. I filled in some more water and also filled in the reservoir until it was flowing out of the top outlet of the radiator. Reconnected hose and put cap back on then started it up. I ran it for about 5-10 minutes and temp was fine, but upper hose seemed stiff. I don’t recall it being stiff before while running. Temp was still good so I shut hood to take it out. Got back in the car and temp was now up to about half way between the line above 80 and the next line next to red. Too warm for me. Shut it down. Upper hose is rock hard.
I suspect the worse but will let it set until tomorrow and see what it does. I guess I didn’t get the the engine filled the first time so it was running with no coolant circulating and didn’t show up on temp gauge. Quite disappointing and all my fault if really blown. Now I’m going to crawl under the 240d and start pulling the slave cylinder and master.
