Quick query folks - not found anything specific on the search though lots of threads suggesting what I may end up doing. My 2002 Mk4 Astra SXi 1.6 16v LPG is nearing 120,000 and is due a full service, cambelt kit etc etc.
I've added ~1 litre of water to the coolant in the past month - I have never had to add water or oil between services in the lifetime of this car which I've owned from new (FSH etc) so I am a little curious what the issue may be. I was advised at the last small service to request the water pump be changed at 120,000 as it is an easy job if the cambelt etc is already off. This I am going to get done, seems sensible.
I am now curious whether I should also consider getting the head gasket done aswell? The service is going to cost enough anyhow (though given up on main dealer pricing now so will save a little there, trust the new garage etc), given I'm now starting to lose water, and the next full service is 40,000 miles away (though only 18 months with 25,000 per year)...is it a simple enough job to do the head gasket if the engine is stripped for the cambelt change anyhow or will it make little difference to the labour charges?
I have not seen any water under the car, there is no trace in the oil nor is the coolant looking a dubious colour (still pretty clear), only issue is I need to get the EGR (and maybe stepper motor) cleaned, not a biggie. Need to do a better visual check on the leak when it stops raining and I remember but it isn't an obvious leak. Nothing weird from the exhaust on startup either. This car ideally needs to last another few years yet, bought it new to keep it as long as possible Nice car too which helps! Never stopped enjoying driving it!
