I seem to remember posts on here recommending the use of some kind of detergent tablets in the coolant to shift crap from the system. Can anyone confirm and remind me what they were, please?
Ron.
That would be me after my oil cooler went from a few spots of oil too totally knackered while doing a steady 80 ish about 50 miles from home
As Al says, if its oil, its a good 6 or 7 tabs opened up and the contents straight into the water tank.
Loo_Knee's way is to remove the radiator then fill with Fernox.
Shake it around for a bit then leave it lying flat over night.
Sieve it out through a pair of your old tights
to get the sludge out then pour the Fernox back in and repeat as many times as time allows
I wouldn't recommend leaving it in the cars cooling system for too long.
Liquid tabs do make the car smell nice too
