Weird Gunk in the Coolant resvoir.
My beloved GTV 3.0 V6 has been giving me a bit of bother recently. One of the flexis went on the exhaust so I have just changed both the front pipe as I figured the other one would not be far behind.
Whilst under the car I noticed a small leak on the radiator. I have now changed the radiator, which was abit of a pain. You have to have drop it out the bottom!! Obviously!!
I have just checked the coolant level now to make sure it all still there and some air hasn't settled out of the system whilst it's been running and it is still full. But, there is some creamy gunk stuff on the inside of tank above the coolant level!!
Does any one know what this is?? Could there have been some oil in the new radiator left from the manufacture process and the gunk is caused by this?? I've checked the oil fill cap on top of the engine and there is no gunk there, thank goodness.
Any help is much appreciated
