Hi
I recently had a head gasket change because there was oil getting into my coolant but now i have oil left in my coolant system.
What is the best way to flush the remaining oil residue from the coolant system please?

Any oil free in the system should work it's way back up to the header tank which you could remove and flush if it worries you. Any in the system that is not showing should not cause any problem, treat it as extra lubrication.
So where does this bit go then ?

Drain coolant, put in a litre of traffic film remover, top up with water and run for a few days.
Drain it all out and thoughly flush it. Any oil left will attack coolant hoses.

That's the stuff but it's much cheaper at the like of euro car parts etc.

Just want to point out was it your head gasket that had gone if not you need to look at the oil cooler leaking oil in to the coolant .

Before the days of " high performance " diesel engines the use of washing powder - surf persil etc - was a good cleaner so I suppose a couple of dish washer tablets would suit this modern age .... don't leave them in for too long though !!

Geoff you are quite right, it's just that traffic film remover is a very high detergent that doesn't foam, I just prefer it.
