So this past weekend I took the Lotus out for a small cruise (around 100 km) with the German Lotus Club. It was the first time I'd really had the car out for a good boot, and it was mostly behaving well.
After parking it (warm) for a while I came back and found a big puddle underneath. Maybe a litre of coolant had come out from somewhere after I'd shut the car off. First time I'd ever seen it happen. I couldn't find anything immediately wrong so I drove it an hour back home where it did the same thing. (It's not condensation from the A/C before anyone asks - it's antifreeze.)
There are no drips or squirts when the motor is running and I stayed and watched for a few minutes after I'd shut it down, but I didn't see it come out right immediately. It looks like it all came out in one big go because the whole crossmember was wet underneath.
The temperature is fine when driving (according to the gauge which may or may not be accurate - some of my other gauges aren't working right at the moment), the fans come on normally, I don't HEAR the coolant boiling or anything to indicate I'm overheating. No idea what's going on here.
Some suggestions of things to look at would be much appreciated!
