Due to recent water hose failures on my mk2 I have decided to replace the lot with silicone hoses.
Today I decided to remove all the coolant hoses to check there condition. I found that four of the coolant hoses including one recently changed had gone brittle inside, looked fine from the outside!
Never had this problem before and am wandering if it was due too using summer coolant this time.
For a while I wondered if I had a head gasket problem due to hoses bursting but carried out a few checks to find its all ok.
I have ordered a new parts from AVS to get me by until my silicones arrive (bet you can't guess the colour?) as they estimate they will be four to six weeks and I cant go that long without my car. sad but true!
