Brother and I are now reaching the end of our tether with the old girl. Sorted the transfer box, and XYZ switch. With the recent hot weather decided to sort out the air con that needed re-gassing. Found a major leak on the top corner of the condenser - how it got punctured there I do not know but such is life. Replaced that and now re-booked in for regassing.
NOW the old girl has decide to play up on coolant.. After a six mile run found water rushing out of the expansion tank overflow. The coolant temperature gauge shows normal temp, The coolant is clean in the tank - no sign of oil or any other muck. The old girl was leaking some coolant with no obvious leaks but O-rings in the cap were looking dodgy so replaced them with new ones and the cap is looking past its best. So the first plan is to put the old ones back in and see if that improves it.
Don't think its the head gasket as there no sign of over-heating or contaminants in the water. Mayne the tank top needs replacing?? Any other suggestions would be appreciated. Cheers Mike
