Overheating and whining noise
Posted: Wed May 27, 2009 11:18 am
Hi all,
We've been extremely diligent at checking coolant levels since getting the Bongo, but have now succumbed to the dreaded overheating problem. It wouldn't surprise me if the cylinder head was cracked (diagnosis tomorrow). My question is has anyone else heard a whining noise coming from the expansion tank area? We suspected it was steam escaping from the expansion tank overflow pipe (almost sounds like the horn actually). The noise generally occurred when the needle (original temp gauge) moved from 11 o'clock to 12 o'clock. The needle would then go back down after a few seconds.
Learnt a few lessons this last week (including fit a coolant alarm - £1500 for a replacement head is a damn sight more expensive than an alarm, eh Haydn?)
