coolant detergent / flush
« on: 17 May 2011, 22:19 »
is there any form of coolant flush/deterent i can run to remove the traces of oil from the system from when my head gasket popped last week?? have flushed with water a few times but it dosnt seem to shift the oily residue from pipes etc, all is running fine since i rebuilt it but all the smeg from the system is making its way to the top (expansion bottle) and would really like to rid this so i can check all is running as it should be!! , oil has been flushed and is fine, hasnt used a drop and is clean, so just want to get this cleaned 100% so i can monitor it to make sure nothing is mixing any more?

cheers for any help

Just be aware that any bio agent will begin to degrade your rubber hoses, o rings, gaskets etc as they are all oil based as well.

Use a mug of non bio Persil, in the system, and run up for 15 to 20 mins, flush out thoroughly, and fill with 50/50 water antifreeze mix.

hhmm food for thought, its a 20 year old car i dont want all perishable bits to go faster than they are already so maybe the flush isnt a good idea?? but then the thought of putting persil in the car seems wrong, might make it smell nice though :)

Just stick in two part Holts rad cleaner Gaz, then stick a hose on the end of the pipe and flush it all out
For the sake of £8 quid I'm sure there is more harmful products in detergents than stuff thats been tried and tested. I know they stick alot of sodium in detergents which is not good for the car LOL.
