Just interested in getting peoples thoughts.....
so, I was merrily driving along the motorway in my mk1...not pegging it. All the gauges were happy and pointing in the right direction. Before I knew it, the water temp gauge was rapidly going up...and I noticed drops of water escaping out the side of the bonnet. Sod's law dictated that this had to happen when there was no hard shoulder, so I had to limp along for approx 1 mile until i could safely pull over.
Once pulled over, the gauge had gone nice and ballistic and up to 110-115. Anyway...obviously I had switched the engine off and let the thing cool down. Whilst waiting for cool down, I noticed the cause of the problem and it was the rubber hose had come off the end of the copper bypass hose that is in front of the rocker cover. Took about 30 seconds to rectify that.
Once I had refilled with magic sauce a.k.a coolant, I fired the car up and drove home...no issues whatsoever and temp was perfect.
However, although all 'seems' well and it drives fine...I'm more concerned about what I can't see/tell. So far I can't see any leakages, oil is still the right colour (no water seems to have mixed itself in)
Any thoughts on whether something nasty might have happened during those few minutes?
