I've had my 2000 superlight for a a little over a month now. Now I know the car has been looked after well and the service history stamps verify this. One of the first things I noticed while poking about was that the coolant was errrrh brown !
As I was going to replace the stat for a 82 deg anyway now was a good time to do it. I drain the system and all the hoses have a thin brown slime coating the interior. I pushed water through the system until it flowed clean (didn't clean all the hoses) drained again then refilled with the correct coolant. So now he system is filled with purple liquid :o). However after a month of usage it has gone brown again. Not as bad as before, you can still just make out its abit purple but mostly brown. Is this normal ? What is the brown slime?
The engine appears in good health with all temperatures and fluid levels remaining stable.
Does this happen to anyone else ? How long does your coolant usually remain its original colour for ?
am I worrying for nothing and basically just need t give the coolant system a good flushing with something other than just plain water ?
Thanks
