Anyone know the answer to this puzzle ?
My Td5 boils over and loses a small amount of fluid after any reasonable run when it get up to temp. . It doesn't overheat during the trip regardless of speed, length, gradients etc. The needle stays smack in the middle.
There is no other leak on the system.
Intersting eh ? Tee's me off though !
so Scothern was, like...
Are you overfilling it? If there are no leaks then possibly it is just dumping any excess and will stay at that level from there on, provided you don't go filling it up again.
IIRC, the Td5 doesn't need much in the overflow tank - just enough to cover the inlet pipe to prevent it syphoning air back in when it cools down. Always check the level when it's cold.
Try *not* topping it up next time and just keep an eye on the level.
OTOH, if it's *really* boiling, then you do have a problem.
Are you sure it is coolant? Do you have air con, because this dumps extracted moisture which can look like a coolant leak after a run? Just a thought.

A previous 300TDi of mine did this when you slowed right down, turned out to be the head gasket!!!
