Can anyone suggest what damage may have been caused by overheating ? I bought myself a nice 55 reg Astra 1.7cdti and only found out on driving it the 200 mile journey home that these cars are not fitted with a low water level light, the level was correct when I set off but had been leaking all the way back through a pinsized hole in a small hose. The car had seemed fine, but stalled when I slowed for a roundabout and when I checked under the bonnet was obviously very hot and steaming from the bottom left rear of the engine which is strangely nowhere near the damaged hose. Since then the engine seems to have a rumble low down and I can only describe the power output as more fluffy. I'm disgusted that Vauxhall dont fit a warning light, I understand the hoses fail often so thought somone might have done a repair or two. Any help appreciated.
