I noticed last night that the old girl was running a bit hot (but enough about the wife :D ) On getting home I found a puddle of coolant behind the front nearside wheel. I can't see any evidence of leaking or burst hoses and so I reckon it's the heater matrix.
Can anyone advise on whether that is likely to be the problem and whether I would need to replace the whole heater matrix?. Any technical tips would also be appreciated if they can save me some time or further grief in the future (i.e. replacing something else at the same time while I've got it in bits)
Cheers
Phil
