Hello to all
Way back in September The wonderful workhorse developed a water leak but not from anywhere obvious. It was eventually tracked by the garage to be a hole in the heater matrix. We saw the damaged part. The garage were not excited about doing the job as access to the heater matrix take a long time.
Part replaced and all went well for 6 weeks when the part failed. The garage had used an after-market part and replaced it with a different make of after-market part. At Christmas this part also failed. The car is about to have a genuine Citroen part fitted hopefully this week.
My question is why would the parts be failing? The garage is an MOT centre with a good reputation in the area.
I wonder if the antifreeze could be unsuitable in some way? I don't think that the engine has ever been flushed out and the car is 12 years old. However in that time the car has always been serviced and maintained following the car service book that came with the car. The water in the radiator when the first matrix failed looked dirty brown and scummy.
I wondered about antifreeze after trying to buy some and finding the variety available now makes it quite difficult to choose. A mechanic in another garage said that the antifreeze needed to be all one type as antifreeze types do not mix and may react with each other.
I have never before needed to top up the radiator but whether a garage at some time has added a different antifreeze from the blue one it started with I just do not know.
Any ideas would be much appreciated.
