I have flushed my block , had it hot tanked (during rebuild) , pressure washed internals , used coke - non diet , white vinegar ,
car is on the road , tried unipart antifreeze , went rusty again - almost like sea water used
flushed thru , vineagared it again , used OAT (red antifreeze) , still rusty
can I use treacle (molasses) & use the car for a week , then flush out (1/3 treacle / 2/3 distilled water)
then a good flush & antifreeze
have heard about treacle used on blocks (non running) - never heard it used in a running engine
what can possibly go wrong - will it eat head gasket or water pump seal , or heater matrix / rad ?
will it go sticky & block up internal water ways - will probably take thermostat out while doing this
what do you reckon ? - maybe less treacle as it's getting hotter ? - what mix ?
I should probably leave it rusty - but don't like the look of rusty water
