Strange Cooling loss !!
Please bear with me a little with this tale. I have had the car now since 2017 and carried out a fair amount of work to get it to be a nice reliable car. I have never had a loss of coolant, and I check all the fluid levels once a week.
About 3 weeks ago, my wife and I set off very early one morning to go and see her mother (130 mile journey). I had gone only a mile or so when I got the low coolant level alarm up. I drove the car back onto the drive and had a look, and it was at the low level. As we were in a hurry, we transferred everything into the wifes car and left. When we came back the next day, I had a look under the car and there appeared to be a coolant patch under the front near side. I refilled the bottle to the correct level and started the car - no leak visible. Ran around the block a few times - no leak visible. Did this for a week. No loss of coolant and no leak visible. Bought some coolant dye and put it in - no leak visible and no loss of coolant. I have been running it for short journeys now for a couple of weeks and no loss of coolant. What the heck ?? If I could see a leak (or had one) I could fix it, but at the moment I'm afraid to do a long journey in case it goes again for some reason. If it wasn't for the alarm coming up, I would have thought it was just an abberation of mine. Am I missing something obvious that may have happened? Thanks

The nearside leak location?
Was it radiator, engine block or bulkhead position, approximately. |

In a recent video, I show how I use my Sealey brake bleeder to mimic cooling system pressure whilst the engine is off to make leak detection easier on a stationary car.
It's worth it's money as a brake bleeder just on its own but having the ability to test cooling systems too makes it a worthwhile investment. Also see this thread whilst although a D5 shows that tiny leaks in the system can be found.

Has anyone been at the radiator drain screw, broke it and done a creative repair?

I'll have a look when I get under - another good thought. Thanks!
