Hope someone can help. How long should i leave radiator flush in the system before draining? Just had the cylinder head done (yes the rover!!) .. And the system was a bit messy and was advised to put a bottle of the flush through..

it is usually only a short run then flush it through, they can be quite caustic, so if left too long may cause leaks.

define short run?
about fifteen minutes is what the packets usually say iirc

you sure you dont mean oil flush? this is the water?
Think my last rad flush to shift scale from a Metro was 30 minutes and I got a slurry of scale out. I'd be worried about leaving it in too long on an alloy engine.
No, really? This group is getting worse...
